Healthy green leaves are the key to long fruiting of cucumbers. But if they have begun to lighten, turn yellow or dry at the edges, it is not worth waiting that the problem will disappear by itself. The earlier you find the cause, the more chances to keep the bushes strong and obtain a rich harvest.

Why the leaves lose the green colour

• Lack of moisture. Cucumbers are very sensitive to drying out of the soil. Even several hot days without sufficient watering can lead to yellowing of the leaves.
• Watering with cold water. If water is used directly from a well or borehole, the roots experience stress, and the plant begins to weaken.
• Lack of nutrition. When the bushes lack nitrogen, the leaves become pale. If yellowness appears at the edges, most often this speaks of a lack of potassium.
• Heat and scorching sun. In strong heat the leaves quickly evaporate moisture and can receive burns, especially if drops of water remain on them after daytime watering.

What to do so that the leaves do not dry out

• Water the cucumbers only with warm water in the morning or evening.
• After each watering slightly loosen the soil or mulch it with grass, straw or hay. This will help preserve moisture and protect the roots from overheating.
• Once every 10–14 days feed the plants with fertilizers containing potassium and microelements. Such feedings help the bushes more easily endure heat and remain green longer.
• Regularly remove yellowed and diseased leaves so that the plant directs strength to the growth of new shoots and fruits.

Do not forget to examine the bushes

Sometimes the cause of yellowing becomes pests or fungal diseases. Examine the leaves from both sides at least once every few days. If you notice spider web, small insects or spots, it is better to carry out the treatment at once, without waiting for the spread of the problem.

With correct care cucumbers recover quickly. Timely watering, feedings and regular examination will help keep the leaves green, and the bushes will delight with an abundant harvest until the end of the season.
