To grow up worthy harvest of cucumbers on the garden site, it is necessary to look after properly culture, to try to create the conditions, most favorable for growth, for saplings. If to ignore some agrotechnical the moments, then, most likely, it will lead to withering of leaves and lashes of plants.
Leaves and lashes of cucumbers are quite sensitive to external influences therefore happens quite difficult to define because of what there is withering of green part of plants. And to prevent the similar phenomenon, it is necessary to give to cucumbers due care, having considered all whims of culture. So, to fade leaves and lashes of cucumbers can because of:
- insufficient watering. Cucumbers - culture hygrophilous, for normal development is required to plant a lot of water. The lack of watering or its rare carrying out always affects plant, at the beginning it is possible to notice withering of some leaflets, however if not to carry out the procedure of watering systematically, then it will lead to death of saplings.
- wrong landing. At frequent landings the cucumbers lack light, water and nutrients, in most cases weaker saplings perish.
- shortcoming or surplus of fertilizers. Cucumbers well grow at enough nutrients in the soil, and here the shortcoming or surplus even of one-two minerals affects culture not in the best way.
- hits of herbicides. Cucumbers are very sensitive to these substances.
- improper neighbourhood. Quite often cucumbers put in one hotbed with other thermophilic cultures, for example, with tomatoes or pepper, and so the similar neighbourhood can negatively affect both cultures. The fact is that plants need different conditions of keeping: some love heat and high humidity, others - the moderate temperature and average air humidity.
- It should be noted that temperature drops do not transfer cucumbers at all therefore it is important to protect saplings from it. Contents in the greenhouse - the best option.
- defeats by wreckers, diseases. To wither to flow and lashes of cucumbers can because of the attack of plant louses and pincers (these insects can be seen on reverse side of leaves), defeats by fungal diseases. Culture is most subject to white and radical decay, in the first case the withering and falling off of the top leaves, in the second - lower is observed. And in that and other case on lashes brown spots appear.
The reasons are found out, now it is necessary to understand what to do to avoid withering of culture. First of all it is necessary to adjust watering and fertilizing. In hot weather it is desirable to water plants daily, but in the small portions, trying to pour in water under the backs, without touching green part. It is better to feed up saplings complex fertilizers not more often than once in 3-4 weeks. For the night it is worth closing the greenhouse (exception - warm nights), to hold doors and window leaves of hotbed open in the afternoon.
At the first signs of the desease of culture or the attack by wreckers not to neglect processings by special means. And to reduce infection probability, healthy plants should be sprayed each 3-5 days with weak solution of potassium permanganate.
