Sowing March-April in the box. In a fixed location to replant in May. Since mid-May it can be sown directly into the ground in seedbed. Leaving plants every 20 cm. Marigold is one of the least involving of ornamental plants. They tolerate drought and heat. There aren’t  also any special requirements for soil - even grow on sterile soil. They prefer sunny positions, but also feel good in partial shade. They bloom continuously since June till the autumn frosts in October. Removing faded flowers will provide long, continuous flowering.
