To get a harvest of cucumbers, they require constant care.
The bushes are also attacked by swarms of harmful insects and fungal diseases, which are not so easy to combat.
Here are the reasons why cucumber leaves dry out in greenhouses:
- violation of the rules for watering cucumbers;
- through fungal diseases such as ascochytosis, downy mildew, and false powdery mildew, which affect the entire plant, starting with the fruits, stems, and leaves of cucumbers - everything begins to dry out and fall off;
- the infestation of cucumbers with harmful insects: aphids, scale insects, mealybugs and mites, which feed on the plant and weaken it, so it begins to dry out;
- if the soil has a very high concentration of organic fertilizers or a lack of them.
Reasons why cucumber leaves dry out
Cucumber leaves dry out when there is a lot of organic fertilizer in the soil. To eliminate the problem, water the cucumbers with plenty of warm water to reduce the concentration of fertilizer.
If the lower leaves of cucumbers dry out, this means that the plant has become ill with root rot or fusarium wilt.
Drying of cucumber ovaries in open ground
When the ovaries on cucumber bushes dry out, it means that they don’t have enough moisture.
Due to fluctuations in air temperature, when the average daily temperature is less than 15°C, the plant weakens, the ovary on it turns yellow, dries up and falls off.
Also, if there is a lack of useful elements, especially calcium, or due to illness\
Processing cucumbers
If cucumbers are affected by disease, treat them with fungicides such as Bordeaux mixture, copper sulfate, Kuproksat, Fitosporin.
And treat against pests with acaricides: Actellic, Aktara, Biotlin, Agravertin, Fitoverm and others.
The main thing is to constantly destroy sucking insects that carry various infections from plant to plant.
Water your cucumbers abundantly and on time at least three times every 7 days.
Cucumber bushes require constant feeding, as they periodically bear fruit, releasing many useful elements from the soil to form a large harvest. A complex balanced fertilizer is suitable for this.
