All gardeners love to feast on cucumbers; in Russia, this vegetable is grown annually. But summer residents often complain that the once juicy and green foliage is covered with yellow spots, dries and fades.
There can be many reasons for this phenomenon, sometimes gardeners take care of the crop incorrectly, allow a lack of moisture or fertilizer.
And with proper care, cucumbers deteriorate, leaves turn yellow - what to do in such a situation and how to help the plants, this article will tell.
Causes of wilting cucumber seedlings.
Often, yellow spots lie in wait for young plants growing on the windowsill. There are several reasons that cause unpleasant changes:
- lack of space;
- attack by pests or disease;
- improper care of sprouts.
Lack of space.
It is important to know that cucumbers are prone to growth and require a lot of space for the full development of the root system.
Peat pots and other containers for seedlings are too cramped, so transplant young plants to a permanent place in time, this should be done after the appearance of a couple of true leaves.
Pests.
Nevertheless, carefully inspect the seedlings and substrate, if necessary, treat them with special means.
Micronutrient deficiencies.
Sometimes the leaves of home seedlings turn yellow due to a lack of fertilizer, and an excess of top dressing can harm young plants.
Replace the soil with a lighter one or add the missing additives.
- With a deficiency of phosphorus, magnesium and potassium, the lower part of the sprout changes,
- but the lack of iron affects the top.
If you have overfed the bushes with nitrogen fertilizers, treat the ground with ash to alleviate the condition of the cucumbers.
Cucumber seedlings are very delicate and plants should be taken care of.
If the pots with seedlings are located on the south window, then you cannot do without a source of shade, because the bright sun's rays will burn the young leaves and the sprouts may die.
Causes of yellowness on cucumbers.
Agricultural technology for growing cucumbers and the appearance of yellowness.
The cucumber leaf often turns yellow due to improper watering of this moisture-loving crop.
Plants need to be irrigated abundantly, otherwise the water will not saturate the entire root system, while scarce and regular watering is considered to be a well-known mistake of gardeners - this provokes the roots to reach the soil surface.
Water generously.
Thus, the culture lacks nutrients, and the tops become covered with yellow spots.
- The watering schedule should directly depend on the weather conditions; in the heat and drought, water the cucumbers every day.
- And at a neutral temperature, it is enough to moisten the soil 2 times a week with settled and warm water.
Don't pour ice water.
It is worth noting that another mistake gardeners make is irrigating a vegetable crop with ice water, thereby summer residents provoke the death of the root system and general oppression of plants.
Apply the liquid strictly under the root, avoiding drops on the greens.
Sunburn also causes the leaves to turn yellow and dry.
In rainy weather.
Top dressing of cucumbers against yellowness.
If the true cause of the appearance of yellowness has been identified and you want to save the plantings, use folk remedies.
The following additives are suitable as fertilizers:
- herbal infusion;
- kefir and bread.
Onion peel.
If the tops brightened during the fruiting period:
- Add 1 cup of onion skins to a large pot of water and bring the mixture to a boil.
- Dilute the filtered broth with water additionally at the rate of 1 liter of top dressing per several liters of liquid and use for irrigation.
This remedy is rich in trace elements and phytoncides that nourish plants and protect them from insects.
Herbal infusion.
Newly planted plants can be protected from yellowness with the help of herbal infusion.
- Mix it with wood ash.
- Which can be supplemented with 10 drops per bucket.
And water the crop with a nutritious and simple fertilizer.
Watering with kefir.
If the lower leaves turn yellow, dilute 2 liters of any kefir in a bucket of water and spray the plants with the resulting composition.
Feeding bread.
Bread top dressing also returns a rich color to cucumbers and saturates the bushes with the necessary components.
Experienced gardeners advise soaking the loaf in a bucket of water for at least 8 hours, then the solution is used to spray the foliage.
The role of biological factors in the yellowing of foliage.
Cucumber leaves turn yellow in the greenhouse due to plant damage by fungal infections.
Diseases such as fusarium and powdery mildew cause clarification and death of the leaf plate, and frequent watering and prolonged rains provoke the reproduction of the pathogen, thereby the culture dies.
The attack of pests also harms cucumbers - aphids suck out all the juices from cucumber tops, so it becomes stained and does not respond to watering and top dressing.
Garlic infusion.
How to deal with misfortune folk remedies?
Garlic infusion will help to cope with a fungal infection.
- Add 50 g of chopped vegetable to 1 liter of water.
- Then put the container with the mixture for 24 hours in a dark place.
- The finished product is diluted with warm soapy water and filtered.
The infusion is very economical - add 1 liter of this folk remedy for each bucket of water.
Bordeaux mixture.
If your garden is affected by pests or causative agents of bacterial diseases, prepare a Bordeaux mixture from the following components:
- copper sulfate (100 g);
- lime (100 g);
- water (10 liters).
Take also 2 plastic buckets:
- In one container, mix copper sulfate and hot water until completely dissolved, add more liquid if necessary.
- And in the second vessel, add lime mixed with water.
- Now pour diluted copper sulfate into the lime mortar
And treat the yellowed leaves of plants. It is best to make 2 treatments every 14 days.
Cucumbers are unpretentious and moisture-loving plants, which means that a gardener needs to make a minimum of effort to get a generous harvest of vegetables.
That's all. It is easy to avoid the appearance of yellowness if you observe crop rotation, water the bushes correctly and use only fertile soil to create beds.
