It is important to respect the planting depth... If the seeds are planted deeper, there is a risk of losing 50% of the crop.

The soil

How to grow radishes in a greenhouse? The soil is prepared in autumn, plant residues from previous crops are removed from it. It is dug up and fertilized with humus.

During the growth of radishes to the beds light loosening and weeding is necessary from weeds.

Disease prevention

The greenhouse uses the same land as the vegetable garden. And just like the rest of the vegetables, radishes are susceptible to diseases... For their prevention, seedlings are sprayed with a solution of laundry soap and wood ash in a 1: 2 ratio.
