How to grow sunflowers in the basin? Sunflowers used for potted plants have a short growth period and can blossom in about 50 days. At the same time, 'vitality', 'happy dwarf', 'Beibei bear', 'golden Monica' and other ornamental sunflowers suitable for potted plants also have more branches, which can produce a lot of bright and beautiful sunflowers one after another, prolonging the viewing time. What is more unique is that none of these varieties have pollen, and people who are allergic to pollen can have close contact with beauty.

Covering soil after sowing, light suppression, such as raising seedlings in winter and spring, can be covered with plastic film to keep warm and shorten the time of seedling emergence. Keep the soil moist after sowing, generally 3 to 5 days in summer and 5 to 10 days in winter and spring. Transplanting as early as possible can not only shorten the slow seedling time, but also prevent the emergence of "tall seedlings". The plant can be transplanted when it grows a pair of true leaves.
