In September, you can begin actively restoring the soil in greenhouses.
Most often we grow tomatoes and cucumbers here.
This means that the selected green manures should primarily prevent fungal diseases and suppress the activity of pathogenic flora. It is also extremely important to restore the balance of nutrients, since the plants actively consumed them.
Which green manures are the best choice for a greenhouse
For nitrogen and potassium
The best options may be any legumes. They will help make the soil fertile and increase the nitrogen content in the soil.
The best in this category are peas and vetch. If we are talking about the balance of potassium, then it is worth paying attention to oats. Also, the use of the crop increases the phosphorus content in the soil.
Mustard
It is worth knowing that planting white mustard is the best prevention of late blight. Also, this green manure generally improves the soil and stops the activity of harmful microorganisms.
Rye
This green manure is also an excellent preventive measure against almost all fungal diseases. Some gardeners advise combining mustard with rye, which will increase the efficiency of using green manure.
