The drain of soil is an essential factor. Heavy clay soil or soil with little organic matter drains inefficiently. They keep too much water around the roots. This makes plants wilt and lose a life.

If you want to improve the soil before planting cucumbers, use organic materials. For 6 inches of clay soil, you must sprinkle 3 to 4 inches of compost or rotted manure. For 6 inches of sandy or loam soil, you need to sprinkle 1 to 2 inches of organic material. You also can try to use mounds.


The temperature of the water, soil, and air is also essential. Cucumbers will become weak in air under 50 degrees Fahrenheit and soil under 62 degrees Fahrenheit. You should change the temperature, so plants have the best condition.

Both vines and leaves wilt; consequently, the plant stops living rapidly after the infection starts.

You must remove and bury infected plants as soon as possible to stop the infection.
