At the beginning of February we start with the first greenhouse plantings. The selection of suitable potting soils is an important prerequisite for successful plant rearing. As the most important organ, they are responsible for the growth and health of the plants. For our potting soils we therefore use selected and best composts from our own production. These have usually been turned twice a year by hand. They are also treated with the biodynamic compost preparations prepared in the WALA garden from the medicinal plants valerian, stinging nettle, oak, chamomile, dandelion and yarrow. The addition of these preparations lastingly enhances the vital forces and processes in soil and plant. In addition they increase the vitality of the plants and the soil and their resistance against disease and pests.
