I dot Not plant seeds in the soil, the soil may be infected you will have a weak plant prone to pests. I therefore sow seeds on Foam, safe from any infection I healthy plant is on the offing. When these grow 3/4 inches, place it in flower pot in an Organic compost mixed with soil, when it about 8 inches I place it in the garden I healthy plant resists infection easily My garden is solely maintained on Organics
