What to do if there are white spots on cucumber leaves

1. Avoid direct cold air

Reason: If cold wind blows directly onto warm leaves, it will cause the leaves to lose their green color and form white spots.

Solution: When letting in air, you should let it in with your back to the wind, and the air outlet should be gradually increased from small to large, and you should not act too hastily. Alternatively, you can hang a piece of plastic film on the inside of the vent to prevent the cold wind from blowing directly at you.

2. Keep warm in time

Reason: If the temperature is above 0 degrees for a long time but lower than the normal growth temperature, the leaves will easily have yellow-white chlorotic spots, and may even cause death. There will also be slow growth or the plant will not take root.

Solution: Find out the cause of the low temperature, adopt insulation measures, control the daytime temperature between 25 and 30 degrees, and the nighttime temperature must not be lower than 10 degrees, preferably between 10 and 18 degrees.
