One of the most dangerous diseases is powdery mildew, which threatens the cucumber harvest.
Unfortunately, this disease is quite common.
It is extremely important to carry out adequate disease prevention when growing vegetables in greenhouses, notes Anastasia Kovrizhnykh , landscape designer and agronomist, expert of the online publication BelNovosti.
How to properly protect cucumbers from disease
First of all, it is worth noting that the plantings should not be too dense. Any gardener tries to grow more cucumbers, so he does not always thin out the seedlings.
For this reason, powdery mildew often appears. Therefore, make sure that the cucumbers are not located too close together. If there is not enough space in the greenhouse, some of the vegetables can be transplanted into open ground.
This is not the only condition that helps protect against the development of powdery mildew. It is extremely important to ensure that there are no drafts in the greenhouse. It is especially important to monitor this point on cold days.
It is important to make sure that it is not too cold at night. It is best to keep the temperature at 18 degrees.
It would also be a good idea to treat the soil with fungicides.
