Dortmund – Even if you take good care of your cucumber plants in the garden, they can still develop yellow leaves. In this case, you need to act quickly. But how can the discoloration occur in the first place?
Cucumber gets yellow leaves: amateur gardeners need to act now
Yellow leaves can be caused by a number of factors, including poor care. Too much moisture, for example. A lack of nutrients can also cause discoloration. In this case, the Lubera gardening platform recommends reducing the amount of water given to the plant “until the substrate has dried out a little.”
If you have never fertilized your plant, you should do so now. Because: “Cucumbers are heavy feeders and need additional fertilization during the growing season in addition to the nutrients found in conventional potting soil.”
Cucumber gets yellow leaves: home gardeners should act immediately in case of fungal infection
Does the plant have yellow leaves even though you have given it plenty of fertilizer and water? Then the cause may be a fungal infection (cucumber wilt, powdery mildew, and downy mildew), explains the website hausgarten.net. “When a plant is infected with mildew, the first thing that appears is a whitish coating” – only then do the leaves turn yellow and fall off.
Although home gardeners cannot save their plants after a fungal infection, they should dispose of the affected plants immediately. It is not advisable to throw them on the compost heap. “The pathogens can survive there and later spread to other plants,” the website explains. It is better to burn the affected plants or dispose of them with household garbage.
