How can we easily use harvested rainwater?

Water cucumbers properly

Cucumbers are heavy eaters and need a lot of liquid to grow. So that the fruits can develop well and do not taste bitter, you must water the cucumber plants regularly and sufficiently.

The composition and nature of the soil also have an impact on how often cucumbers have to be watered: The soil should be rich in humus and loose, be able to warm up easily and be able to store sufficient moisture. Because: cucumbers are shallow-rooted and hungry for air. If the irrigation water seeps away too quickly because the soil is very permeable, the cucumber roots only have a short window of time to absorb liquid from the earth. Compaction and waterlogging, on the other hand, also damage the vegetables and can be reasons for the fact that only a few, too small or no fruits develop.

How to properly water cucumbers

In order for cucumbers to have uniform soil moisture, they must be watered in good time. Always water the vegetables in the morning using warm water that has been collected beforehand, for example in a rain barrel or watering can. The lukewarm or ambient warm rainwater is important so that the cucumber plants do not suffer a cold shock. In addition, the summer vegetables do not get the tap water, as it is often very hard and calcareous. As a guide, a cucumber plant needs twelve liters of water for each harvested cucumber during the entire cultivation phase.

If possible, only water around the root area and avoid the leaves, as damp leaves can encourage infestation with diseases such as downy mildew. In the case of free-range cucumbers, it is also advisable to mulch the soil with a layer of lawn clippings or straw. This prevents excessive evaporation and protects the soil from drying out prematurely.

Pay attention to regular watering, because too dry a culture can easily lead to powdery mildew and bitter fruits. With snake cucumbers, also called cucumbers, which are mainly grown in the greenhouse, you should always ensure a warm and humid microclimate. A humidity of 60 percent is ideal. Therefore, on hot days, spray the paths in the greenhouse with water several times a day.

If you adhere to these rules and other care tips for growing cucumbers and fertilize the cucumber plants twice over the summer as soon as the first fruits have formed with a strengthening plant manure, for example nettle manure, nothing stands in the way of a rich cucumber harvest.

More and more hobby gardeners swear by homemade manure as a plant strengthener. The nettle is particularly rich in silica, potassium and nitrogen. In this video, MEIN SCHÖNER GARTEN editor Dieke van Dieken shows you how to make a strengthening liquid manure from it.
