What to do when the leaves of cucumber seedlings turn yellow


Many gardeners use the seedling method of growing cucumbers to get an early harvest. Anxious care of seedlings does not always give the desired result. One of the most common problems is that the leaves begin to turn yellow. Seedlings are also susceptible to this. Why this happens and what to do - this is the article about this.

Reasons why cucumbers have a yellow leaf

Why can yellow or white spots appear, diseases develop, fruits fall off, stems dry out? The yellowness of the leaves can appear for a number of reasons. You should not immediately get rid of damaged shoots, first you need to figure it out. The general picture of the state of the soil, the root system will prompt the criticality of the situation and help determine what to spray cucumbers with and what other activities should be started immediately. Gardeners distinguish the following among the main reasons for yellowing of leaves:

  • lack of light, it does not allow the plant to develop;
  • deficiency or excess of nutrients in soil (especially nitrogen and manganese);
  • violation of the irrigation regime (waterlogging or drying out of the soil);
  • overgrowth of the seedling (there is little space for the roots in the container used for germination);
  • unstable temperature conditions;
  • the effect of toxic substances (observed when using foam and other polymers for growing seedlings);
  • disease damage to the plant or pests.

What causes the seedlings to turn yellow and dry, how to save it

If the cotyledon leaves turn yellow on the seedling material, begin to dry out, then the reason lies in the new shoots with which the seedling grows. To rectify the situation, it is enough to remove unnecessary branches or ovaries. Violations in agricultural technology are also not excluded. Experts recommend, before starting seasonal work, draw up a schedule of necessary activities, sow, plant and transplant, spray and fertilize on time.
Greens of seedlings can turn yellow from low temperatures (especially with night frosts on the ground). That is why, when planting seeds on an open bed, you need to cover it overnight with a film or agrotextile.
Seedlings are sensitive to the lack of useful trace elements, in particular potassium, and this must be fought. It is important to adhere to the timing of top dressing, so that the developing plant has enough strength and energy for normal growth.

When yellowness appears on seedlings only in a certain zone of the beds, it is rather associated with an incorrectly chosen place. The problem is most likely in the composition of the soil or in the lack of light. When growing seedlings on a windowsill, it is important to prevent the soil from drying out and direct sunlight, they can burn, light shading is required.

Yellow leaves of seedlings in a greenhouse, with what to fight

When growing cucumbers in a greenhouse, the moisture and temperature regime is often violated. Excessive moisture in the air and soil leads to the development of fungal diseases. The plant reacts to a deviation in the external environment with yellow leaves. At first, the tips turn yellow, then the entire sheet can be covered. You should not ignore this signal.

Normal conditions for the development of seedlings provide for a temperature in the range of 22-26 degrees. If the indicator falls below 14 ° or exceeds + 42 °, cucumber shoots stop developing, and just one degree of frost leads to death. Yellowing leaves and embryos can signal a violation of the temperature regime.

Other possible reasons include:

  • insufficient pollination, as a result of which ovaries are poorly formed on the plant;
  • congestion of the shoot with ovaries;
  • fungal or insect damage;
  • lack of nitrogen and other microelements in the soil.

Yellowness on street plants, diseases

When growing cucumbers in open ground, the yellowness of the leaves often indicates a violation of watering: a lack or excess of moisture. In extreme heat, it is recommended to water the bushes daily (morning or evening). If the summer temperature is moderate, then it is enough to irrigate the beds 2-3 times a week. But before each procedure, it is worth assessing the condition of the soil in order to prevent stagnation of water. You should also loosen the soil in a timely manner.

If we are talking about the defeat of the plant by diseases, then the yellowness or white dots on the greenery indicates fungal infections: fusarium, pityosis, etc. The leaf does not react to watering, it remains sluggish. It is necessary to treat: it is necessary to treat with special preparations, you cannot do without it. The main thing is not to waste time so that the affected area does not spread to neighboring bushes. And there is no need to rely on folk methods, it is better to act according to science.

Yellowness or a white spot on the leaves may indicate pest infestation. Among the most dangerous parasites are spider mites, whiteflies, and aphids. Insects suck the juices from the plant, which leads to its death. In this case, you cannot do without processing the beds.

How to deal with yellowing of leaves

One of the rules for caring for cucumbers says that damaged areas should be removed to localize the problem. In the case of yellowing of the leaf, there is no need to rush, treatment is necessary here. To begin with, you should control the ambient temperature, soil condition. This will help identify violations and correct them.

Top dressing - improve the soil in the greenhouse

In addition to moisture and looseness, the soil must be nutritious... Growing seedlings remove most of the microelements necessary for development from the soil. Therefore, in agricultural technology, there is a schedule for the introduction of dressings, which enriches the environment with useful substances, helps to strengthen the plant's immune system. There are two ways to introduce a beneficial substance. One is to sprinkle with the ready-made solution, the second is to sprinkle dry granules of factory production according to the instructions and pour plenty of water.

If the leaves turn yellow and dry at the edges, then most likely there is a lack of potassium and magnesium. And if green veins remain on the yellow leaf, we can talk about a deficiency of manganese and iron. In case of yellowing of the upper part of the bush, a copper deficiency is diagnosed.

To fix the situation you need to carry out complex feeding in a timely manner... Alternate organic with mineral, as well as root and foliar. Nutrient administration schedule:

  • the first time to feed the cucumbers should be when one leaf appears on the seedlings (ammophoska; azofoska; manure; bird droppings; herbal infusions);
  • the second time falls at the beginning of the flowering period (solution of water and wood ash 10 l / 1 glass; potassium and ammonium nitrate 20 and 30 grams, superphosphate 40 grams per bucket of water);
  • the third feeding is carried out during the active period of fruiting (solution of nitrophoska 10 liters of water per tbsp. l. means; solution of water 10 liters, mullein 0.5 liters and potassium sulfate 1 tsp);
  • the fourth top dressing is used for varieties with a long fruiting period (a solution of wood ash, manure or bird droppings).

Proper watering does not allow the soil to dry out

It is necessary to correct the irrigation error taking into account the following factors:

  • type of soil;
  • the age of the cucumbers;
  • features of agricultural technology varieties;
  • weather conditions.

To protect the plants from drying out, it is recommended to cover the beds with mulch. This will keep soil moisture longer in hot weather. In this case, you do not have to flood the plants, as a result of which a fungal disease may develop.

Important!
When choosing an irrigation system, give preference to sprinkling and drip irrigation. Dosed moisturizing will also prevent powdery mildew, root rot, and olive rot.

Organizing automated hydroponics for a novice gardener will not be possible.
In the open ground, you need to moisten the garden more often than when growing greenhouses in a greenhouse... Beginners should use watering rates per bush as a basis:

  • with an shoot age of up to 1 month, 0.5-1 liters of water will be required;
  • from 1 to 2 months, the water rate increases to 1.5 liters;
  • from 2 to 3 months - up to 2-2.5 liters;
  • over 3 months - up to 3-3.5 liters.

Light and temperature, do not let the plant turn yellow

A characteristic sign of a lack of light is yellowing of the lower leaves on the bushes. It is impossible to change the landing site of developed bushes, therefore, weeding should be carried out in a timely manner so that weeds do not form a shadow. Also, during the formation of the lash, you need to take care that neighboring plants do not spread on top of each other. This will not happen if the recommended layout is taken into account when disembarking. Observance of the intervals will help to prevent the bed from becoming thick.
Temperature changes also affect the color of the cucumber leaf. It is impossible to influence nature, but it will be possible to save the plant from low temperatures by constructing a frame and covering with a film... If the climate is arid, then the planting of cucumbers should be done between corn or sunflower. Neighboring crops will scatter sunlight, prevent the formation of burns on the green.

Errors when landing in open ground

It is often difficult to correct mistakes when yellowness is detected on the sheets, because the reasons may lie in the wrong planting of seedlings or seeds. Therefore, it is important to comply with the basic requirements at the beginning of the formation of beds:

  • every season change the place for cucumbers (you can return to the previous one after 3-4 years);
  • observe the distance between the holes, do not save on the aisle;
  • do not use more fertilizers than indicated on the package, excess nitrogen, for example, burns out a young plant;
  • before planting seedlings, it is hardened for at least a week;
  • when choosing neighbors, the coexistence of cultures is taken into account.

Pest control, remedies

If the garden bed is attacked by pests, treatment with insecticides and acaricides is carried out. Among the popular drugs, the following are noted:

  • Aktara (spraying the plant with a solution of 10 liters of water and 2 gr.);
  • Actellik (spraying plants with a solution of 10 liters of water and 30 ml of the product);
  • Thunder (applied to the soil with a depth of 3-5 cm 30 g / 10 m2);
  • Thunderstorm (granules are scattered in a row spacing of 30 g / 10 m2);
  • Fitoverm (before planting seedlings for 2-3 days, powder is scattered over the surface of the soil 200 g / 1 m2, followed by deepening by 15 cm).

Prevent yellowing, spray with nutrient mixture

For prevention purposes, it is recommended to follow simple rules:
before sowing, carefully prepare the soil, enrich it with nutrients in the right proportions (you should not increase the fertilizer consumption rate);

  • change the place for a cucumber bed annually;
  • seedlings with 2-3 leaves should be sprayed with a nutrient mixture of water (10 l), milk (1 l), iodine (30 drops) and laundry soap (20 g);
  • for watering, use the nutrient liquid obtained after infusing bread with water;
  • dusting the surface of the soil with wood ash will not only neutralize the acidic soil, but will also protect against pests.

You may not even encounter the problem of yellowing if you follow all the rules of care and prevention in a timely manner. It is much easier than spending energy and nerves to restore the affected plant.


Cucumber is an extremely thermophilic crop, so its cultivation most often takes place in greenhouses and greenhouses. The close proximity of plants, as well as not always favorable conditions for growth, can lead to yellowing of the leaves of this plant. What to look for the cause of this phenomenon and what needs to be done for prevention and treatment is described below.

The main reasons for yellowing of leaves in a greenhouse:

    Insufficient watering... The moisture inside this structure lingers for a long time, but with increased dryness in the greenhouse, the plant may turn yellow. To prevent this from happening, it is necessary to carry out regular ventilation, as well as to ensure a comfortable temperature.

  • Watering with cold water. Experienced gardeners know for sure that for watering cucumbers it is necessary to harvest water in advance. It is better if it has time to settle for at least a day, and experts advise keeping a special container on the site, the water level in which to restore after each watering. So for cucumbers and other capricious crops there will always be warm, settled water in stock.
  • Poor soil composition... Constant planting in the same place depletes and depletes the soil composition. It is for this that the rules of crop rotation are used, and planting of green manure plants is also carried out, which enrich the soil after mowing.
  • Drafts in the greenhouse... Good ventilation helps cucumbers grow, but uncontrolled gusts of wind can kill plants. For ventilation, it is advisable to provide an opening sash, but perform this procedure only as needed. It will also be helpful to learn about what varieties of cucumbers look like for growing in a barrel.

    In addition, cucumbers are often affected by diseases and pests. The juicy stem and fruits become a favorite delicacy for many garden "newcomers", and sometimes, for effective protection, you have to use not only folk methods, but also purchased products.

    Possible diseases and pests - the reason for the yellowing of cucumber leaves:

      Powdery mildew... The most common disease. Leads to gradual blanching of leaves and curling of their edges. The disease is caused by a separate fungal stamp, therefore waterlogging is considered the main cause. You can fight this scourge with the help of special means. Such preparations are perfect: "Baylon", "Karatan", "Kuproksat", "Acrobat" or "Bravo". But how to remove powdery mildew from gooseberries, this information will help you figure it out.

    Spider mite... A small insect that causes considerable damage to plantings. In addition to special preparations, you can use a solution of laundry soap. With the help of a sponge, the outer and inner parts of the leaves, as well as the stem of the seedlings, are processed. But how to get rid of a kidney mite on currants is described in great detail in this video.

    Melon aphid... Ordinary soap solution is also effective against it. Treatment can be carried out for prevention and treatment no more than once a week. And by clicking on the link, you can find out more about the gall aphid on red currants, and how to deal with it.

    Root rot can also kill crops.... The factors that provoke the risk of such a disease are waterlogging and watering with cold water. "Previkur" is considered an effective remedy for combating root rot. Processing is carried out according to the instructions with an interval of two weeks. It will also be useful to learn how to spray tomatoes from black rot.

    Fusarioh - a fungal disease against which most fungicides are powerless. Prevention methods are considered to be regular loosening of the soil, as well as a change in the place of growth and disinfection of the land, carried out every season.

    A timely identified pest is the key to successful treatment of cucumber seedlings. At the same time, you need to know that with constant problems of a certain culture at the planting site, you may have to completely abandon the cultivation of plants on this soil.

    Cucumber leaves turn yellow and dry in the open field

    Let's start with the reasons why cucumber leaves can turn yellow. And there are several such reasons:

    1. Plants lack nutrients. Or, if there is an excess of trace elements.
    2. Insufficient watering or, on the contrary, waterlogging.
    3. The plant is sick or pests interfere with it for proper growth and development.
    4. Climatic conditions.

    And briefly about each of the reasons.

    1. The plant assimilates liquid mixtures and complex fertilizers better.

    For the entire growing season, you need to carry out 3 dressings:

    • With the appearance of two true leaves.
    • During flowering.
    • With the appearance of the first ovaries.

    In order not to "overfeed" the plants, you need to strictly follow the instructions that come with each fertilizer.

    Yellow spots indicate a lack of potassium, and light green spots are a sign of magnesium deficiency. So, the cucumbers need to be fed. Yellowing upper leaves are with a lack of copper.

    2. There is a misconception that the more water for watering cucumbers, the better. In fact, even a large amount of water will not save if the irrigation was not correct.

    • Water the bush at the root, not on the leaves.
    • Watering time is early morning or late evening, when the sun is no longer baking.
    • It is better to use warm water, the one that has settled under the sun.

    3. Such fungal diseases as fusarium or pityosis can appear due to temperature changes, and are manifested in a change in the color of the leaves on the bush. To prevent these diseases, it is worth treating cucumber bushes with "Fitosporin".

    From pests such as whitefly or spider mite, will save "Antiklesch", "Fitoverm", "Apollo". Deal with fungus a 1% solution of Bordeaux liquid will help.

    From aphids you can spray the cucumbers with a solution of nitroammophoska (3 tablespoons per 10 liters of water). A solution of colloidal sulfur (80 g per 10 l of water) will cope with a spider mite.

    If the roots of the cucumber are eaten by pests, or they were damaged when planting seedlings in the ground, during weeding or loosening, the leaves will inevitably begin to turn yellow.

    Do not thicken the planting. First, it limits the sun's rays from reaching the bottom of the plants, causing the leaves to turn yellow and die off. Secondly, fungal infections appear.

    4. A sudden change in temperature or heat may cause a problem. A properly selected shady landing site or a stretched mesh that shades the landing will save you from the heat. Treatment of bushes with a solution that stimulates growth will help from a cold snap. To prevent fungal diseases from developing, regulate the humidity by ventilating the balcony or greenhouse.


    Leaves of cucumber seedlings turn yellow: what to do if they dry

    Often, gardeners, when growing vegetables, are faced with the problem of yellowing foliage. Consider why the leaves of cucumber seedlings turn yellow and how to deal with it.

    Causes of yellowing of leaves in cucumber seedlings and treatment methods

    Main reasons

    Cucumber seedlings turn yellow for several reasons. If the source of the problem is discovered in time, then the plant can be saved.

    Tight capacity

    As the seedlings grow, they build up the root system. When the crops are thickened, the plants suffer from a lack of moisture, nutrients and space, reacting to this by wilting and yellowing of the aboveground part.

    Lack of nutrients in the soil

    It is possible to determine from the lack of which element the sprouts suffer from by the place of yellowing of the cucumbers: along the edge - a sign of a lack of potassium, in the area of ​​the veins - the seedlings lack magnesium.

    Toxin poisoning

    Usually, the seedling boxes are placed on top of a foam pad, which, when in contact with fertilizers or moisture, can release toxic substances.

    Harmful components cause yellowing, wilting and drying of leaves and pose a great danger to both plants and future fruits.

    Temperature violation

    If the temperature in the room is below 18 °, the process of hypothermia of the soil occurs, as a result of which the plants are not able to fully accept nutrient components.

    Improper watering and lighting

    Often the reason lies in a lack or an excess of moisture - watering must comply with the norm.

    Also, seedlings grown on the southern or southwestern windowsill turn yellow and curl, where the sun is especially active at midday.

    But do not forget that with a lack of lighting, the seedlings will suffer no less.

    Disease and pests

    Yellowness can be the cause of the appearance of fungal diseases - powdery mildew, downy mildew, fusarium wilt or root rot. Or a consequence of an attack of parasites - spider mites, aphids.

    Treatment methods

    We process to eliminate fungus

    Different methods of treatment are used for yellowing of cucumber seedlings.

    1. If the plants wither from fungal diseases, it is necessary to carry out treatment with biological preparations - Albit, Alirin-B or Gamair. These funds are effective at the initial stage of infection. In a neglected form, fungicides are used - Topaz, Bayleton, Tiovit-Jet, Raek. From folk remedies, an ash solution is successfully used (for 5 liters of boiling water, 1 liter of wood ash), it is infused for a day, then 40 g of crushed laundry soap is added. Irrigate twice with an interval of 7 days. Also, seedlings can be treated with a solution of soda ash (1/3 teaspoon of soda is placed per liter of water).
    2. When pests appear, use any insecticide (Skor, Actellik or Aktara). Some gardeners use milk whey or kefir in the fight against aphids and spider mites: dissolve 1 liter in 5 liters of water, then irrigate the soil and the aboveground part.
    3. For resuscitation from sunburn, seedlings are irrigated, not in the afternoon, but in the morning or evening. Provide sun protection during midday hours.

    Preventive actions

    Prevention of yellowing of cucumber leaves will be proper care and adherence to all rules of agricultural technology.

    1. Temperature range within 22-25 °. This condition applies to plants grown in a greenhouse and at home.
    2. Lack of drafts and sudden temperature changes.
    3. Regular moistening of the soil from a spray bottle and only as the top layer of the earth dries out.
    4. To prevent the seedlings from turning yellow, they need diffused daylight, with protection from the scorching sun, at noon hours.
    5. Regular nutrition with nitrogen-containing preparations that contribute to the growth of the root system and green mass. Seedlings are fertilized once, 10 days after sowing, with a solution of mullein diluted with water (1:10) or with a solution of poultry droppings (concentration 1:15).
    6. To restore damaged roots after transplantation, a complex fertilizer should be carried out - superphosphate with potassium salt. These components help to repair damaged tissues and stimulate their growth.

    Helpful hints

    There are many reasons for the yellowing of cucumber seedlings. In order to avoid this phenomenon from the very beginning and get strong shoots, you need to follow all the rules of planting and care - then you will get a healthy and rich harvest.

    For planting, you need to take only high-quality seeds - without signs of yellowing, mold, and disease damage.

    First, they should be etched with a solution of potassium permanganate, and one of the biological products for vegetable crops, Albit or Gamair, should be added to the soil.

    Why do the leaves of cucumber seedlings turn yellow? Causes and Effective Solution of the Problem. Why leaves turn yellow on seedlings and how to fix it. Causes and elimination of yellowing of leaves!

    [/ su_box] When planting, use spacious seedling boxes or containers with a height of at least 15 cm. To eliminate the risk of overflow, use containers with drainage holes.

    The soil is disinfected, which helps to avoid pest and disease infestation. There are several methods of sterilization - calcining in the oven, spilling with boiling water or a solution of potassium permanganate.


    The appearance of yellowness on the leaf blades - in the middle, along the edge, twisting of the border, wilting - all this can be caused by various reasons. Sometimes it is enough to reconsider something in the care of plants; in other cases, drastic measures will be required.

    Ask and get useful advice from professional gardeners and experienced summer residents. Ask a question >>

    Why leaves turn yellow and dry:

    • violation of the irrigation regime. An excess of moisture or a deficiency is equally dangerous for seedlings. An excessive amount of water in the soil provokes rotting of the roots, the leaves turn yellow, dry, die. Drought causes stretching and also yellowing of plants (see photo)
    • lack of sunlight. Although cucumbers are not sown for seedlings as early as tomatoes or peppers, the problem of low light exists. On the windowsills in the apartment in the spring, it can be difficult for gardeners to arrange boxes and cups with seedlings of many crops, and therefore someone has enough light, while others do not.
    • burn from direct sunlight. The spring sun is bright, burning, and therefore dangerous for young and tender cucumber seedlings. Watering when water gets on the leaves can complicate the problem. Under the rays of the sun, the drop "works" as a lens, increasing the temperature many times over, causing the plant to burn the leaf blade
    • malnutrition. Strong healthy seedlings are grown only on fertile soil mixtures. If a poor-quality mixture with a small amount of nutrients is used for seedlings, then almost immediately the seedlings will "declare" a nutritional deficiency with the appearance of yellowness and poor growth. But there may be another situation - an excess of minerals, when the plants are "fed" and begin to turn yellow
    • wrong pick. Cucumbers do not tolerate transplanting well, they adapt for a long time to new growing conditions, and get sick. If the roots are damaged during a dive, the cotyledon leaves dry out, and then yellow spots may appear throughout the plant
    • the use of low-quality containers (pots, cups), as well as improvised materials that emit fumes harmful to plants
    • lack of space in pots
    • sudden changes in temperature
    • diseases of cucumber seedlings (fungal, viral)
    • pests (aphids, spider mites).

    It is necessary to find out as soon as possible the reason for the change in the color of the leaves, to be in time before the dying off of the root system of cucumbers. It is expensive every day, otherwise the seedlings will be ruined, and re-sowing is a waste of time.


    Why do cucumber seedlings turn yellow

    The following main reasons for the appearance of yellowness on cucumber seedlings can be distinguished:

    • The reason for the yellowing of the leaves of cucumber seedlings may be a lack of light. In this case, yellowness may be observed on the lower leaves of plants, followed by their withering away. This is due to the fact that the penetration of sunlight to the lower tier can be limited due to the volume of the upper foliage. With such a phenomenon, it is necessary to remove the wilting leaves in a timely manner so that the dying leaves do not draw on some of the oxygen and nutrients.
    • Next possible the reason for the yellowing of cucumber seedlings - excess or insufficient amount of moisture. In moderate weather during the summer, cucumbers need to be watered abundantly three times a week, and in case of rather hot weather, watering should be done daily. If the roots of cucumbers do not receive the required amount of water, they tend to rise, which contributes to the release of the root system from the ground, followed by their drying. If we talk about an excess of moisture, then in this case, the root system begins to rot, which ultimately also manifests itself as yellowing of the seedlings.
    • Influence the seedlings, maybe plant damage by fungal diseases, which is manifested by the appearance of rusty spots on the leaves, followed by wilting of seedlings. As a rule, the appearance of fungal diseases can be affected by a sharp change in the weather.
    • The appearance of harmful insects can also cause the appearance of yellowness on the plant. The spider mite or whitefly drinks the juice from the cucumber tops and leaves, which, as a result, leads to the death of the plant. You can fight pests only by spraying cucumbers with special chemicals that are sold in specialized gardening stores... But if there is a need to get an exceptionally clean crop, then the independent preparation of organic solutions for the destruction of insects will help here.
    • The most common reason for the appearance of yellowness on the leaves is considered a lack of nutrients. It happens that cucumbers are grown in the same areas of the garden for several years. It is important to remember that leads to soil impoverishment... Lack of micro- or macroelements can be manifested by yellowing of the edges of the seedlings, followed by their drying. In order to avoid such problems or to eliminate them, timely feeding of the plant will help in compliance with the rules of agricultural technology.
    • The manifestation of yellowness can be a signal that the plant has undergone hypothermia. The Indian jungle is considered the homeland of cucumbers, in which there is a rather hot and humid climate, so the thermophilic plant suffers greatly at the time of cold snaps or prolonged rains.
    • Damage to the roots of cucumber seedlings also leads to the appearance of yellowness. This phenomenon is due to the fact that the nutrition of the plant passes through the root system, and if its normal functioning is disturbed, the plant begins to die, and this manifests itself first through the leaves. This phenomenon can occur when the seedlings were planted in open ground too early, or if the roots close to the surface were mechanically damaged when removing weeds or loosening the soil. Therefore, it is best to replace loosening the soil with mulching, and pulling out weeds with cutting them at ground level.
    • Yellowing of foliage can be the result of sunburn, which manifests itself on the plant in the form of pale yellow spots. In order to avoid such a phenomenon, it is necessary to water the plant exclusively at the root, and during greenhouse cultivation, monitor so that condensation does not collect on the leaves. As a rule, in this case, there is no particular reason for excitement, the main thing is to prevent the repeated ingress of moisture on the cucumber seedlings in the future in bright sunlight.
    • In addition to the main listed reasons caused by external stimuli or negative factors, one should not forget about an absolutely natural phenomenon that causes yellowing of foliage - physical old age of the plant... Thus, seedlings may turn yellow at the end of the season, when the plant is already starting to die off.
