Prepare soil before planting. Clean the place where you want to plant the seedlings from pollutants (concrete, stone, metal waste, etc.). In the season before planting the crop it is recommend to cultivate e.g. beans, peas, lupine and vetch, which should be digged in full flower period, before the joinder of the seeds.
Natural organic fertilizers are conducive to the good development of the vine. You can fertilize with manure in a dose of 5-7kg/m2. The manure is spread uniformly on the surface of the soil and digs in to a depth of 30cm. In the gardens where the manure is not possible, it can be replaced with compost. Compost is used in a dose of approx. 10 kg/m2.
