During August, cucumbers require frequent feeding to produce plump and crisp fruits. One effective and time-tested method involves using a simple fertilizer, popular since the Soviet era.
Start by preparing an onion peel infusion. Place the peels from 6-8 onions into a jar, pour a liter of hot water over them, and cover with a lid. Allow this mixture to sit for 24 hours. After this period, strain the liquid and add one tablespoon of potassium sulfate. Dilute this mixture to make 10 liters of the final solution and spray your cucumber plants with it in the morning. A single application in August is sufficient to rejuvenate your cucumbers and enhance their yield.
