Crispy cucumbers - a dream of every owner of a small garden. Agree, your own harvest is always tastier than vegetables from the market. In addition, the cultivation of cucumbers - it's almost insufferable. True, sometimes gardeners face some problems. For example, one of the most frequent is the twisting of leaves in plants.
Why are the leaves curled in cucumbers?
The most common reason why cucumbers are twisted young leaves is the lack of essential nutrients, most often nitrogen, magnesium, calcium or sulfur. The same phenomenon occurs with a lack of moisture and drought: in hot weather, the plant has to twist the sheet into the tube, thereby reducing the area of evaporation. In addition, the leaves of cucumbers are curled and dry because of a viral disease or pest, for example, wireworms, aphids, etc. When growing the same in a greenhouse, cucumbers react in this way to high humidity.
The leaves of cucumbers twist - what should I do?
It is clear that the methods of treatment of a favorite vegetable depend on the cause that caused the folding of leaves:
- If you suspect that your pets respond so to a lack of moisture and drought, your actions should be reduced to the next. First, carefully gently ground around the roots of the plant. Then pour abundantly on the soil of the beds. And, by the way, do not forget to cover the land with mulch to reduce the evaporation of moisture. To remove stress in plants, spraying or watering with a solution of a biostimulator, for example, Epin, Regoplant, Biolan, Radostim and others, will help.
- In the event that you have all the prerequisites that the leaves of cucumbers are curled inward and pale because of a lack of nutrients, you will have to make the necessary additional fertilizing. A good result is after the introduction of a complex fertilizer, for example, Diammofos, Sudarushka, Agricola, Master and others. The agent is diluted in water according to the instructions or introduced into the ground in the form of a powder. It's important not to overdo it! By the way, simple spraying of the ground portion of the cucumber with a weak fertilizer solution also helps.
- Pests are a separate problem. Most often there is a mite and melon aphid, whose colonies settle on the inner sides of the leaves. As for what to treat, when the cucumbers are twisted leaves, many experienced vegetable gardens recommend to process the beds with a solution of laundry soap. It is prepared from a bucket of water and 150-200 g of soap shavings. A good result from pests is the so-called lye, obtained by mixing in 10 liters of water, 50 g of ground soap and 200 g of wood ash. If you do not want to bother with the preparation of solutions, purchase an insecticide at a specialized store, for example, Metaphos, Dash, Carbophos, Kinmiks, IntaVir and others. However, keep in mind that these chemicals can only be used three weeks before the ovary, since they are toxic and can accumulate. Biopreparations are considered safe, for example, Bitoksibatsillin, Fitoverm, Aktofit. Across
Two days after the treatment of the fruits can be safely eaten. - Cucumbers, folding in a closed ground due to high temperature and waterlogging, are treated with frequent airing of the greenhouse and loosening of the soil. It is important to establish the correct temperature regime and watering.
- If we talk about how to spray cucumbers, if the leaves are twisted because of a viral disease of powdery mildew , then you can try infusion of mullein by diluting it with 1 part with 4 parts of water. From false powdery mildew helps sprinkle with infusion of wood ash (1 tablespoon diluted in a liter of boiling water) or Bordeaux liquid .
