Tips for watering cucumbers

Growing cucumbers in a greenhouse during the warm season requires maintaining the right level of soil moisture. Before the plant begins to flower, it is recommended to water in the morning. Once flowering starts, the best time to water is in the evening, after sunset. The optimal water temperature is +21–25°C and should never be lower than +12°C.

Young plants need about 4–5 liters of water per square meter every 2–3 days. At this stage, cucumbers do not produce many leaves but focus on forming shoots. When the plant begins to flower, water requirements typically increase to 10–12 liters every 3 days. Once fruit development starts, plants may need as much as 12–13 liters of water per square meter. Determining the exact amount of water for each plant is not easy, but a simple rule can be followed: if you grow 3 cucumber plants per square meter, divide the recommended water amount by 3. This gives an approximate rate of 3–4 liters per plant every three days once flowering begins.

How to tell if cucumbers are getting the right amount of water?

Yellowing leaves, slow growth, mold, fungus, or rotting roots indicate overwatering. If you notice these problems, immediately reduce the amount of water and allow the soil to dry more thoroughly before watering again.

If cucumbers receive too little water and soil moisture is low, growth will slow, the soil will appear overly dry, and plants may wilt or curl their leaves. To ensure optimal growth, it is recommended to regularly inspect and assess the plant’s condition. The best time to do this is during the hottest part of the day, when wilting is most visible.

How to determine whether cucumbers receive the optimal amount of water?

If your cucumbers are given too little water and the soil moisture is low, you will experience slow cucumber growth, the soil will look too dry visually, and your cucumbers will wither or curl their leaves. In order to ensure optimal growth of cucumbers, it is recommended to regularly inspect and assess the appearance of the plant, it is best to do this during the warmest time of the day, as wilting of the plant is most obvious at that time.
