Dwarf sunflower for containers and small garden beds, perfect for children to plant! Big Smile has the classic bright sunny-yellow petals with a dark center. Compact, branching plants are 25-38cm when grown in pots and slightly taller at 30-60cm (12-24”) when grown in the garden. Bears Pollen.
How To Grow, Timing: Direct sow repeatedly after the last frost date. Starting indoors is possible, but does not gain much time. If sunflowers are allowed to get root-bound, they will lack stability at transplant time, and will require staking. Optimal soil temperature for germination: 21-30°C. Seeds should sprout in 10-14 days.
How To Grow, Starting: Sow seeds 5mm-1cm deep. Space dwarf varieties 15cm apart, but give the giants lots of room at 1m between plants.
How To Grow, Growing: To grow really big plants with really big flowers, enrich the soil with organic matter and incorporate 2 cups of balanced organic fertilizer per 3m of row, and irrigate regularly. When the plants are 30cm tall, dissolve 5ml of borax (for boron) in 350 ml of water and spread the solution over 5m of row. Be careful not to over-apply this solution. This application of boron will produce bigger seeds and flower heads. Do not apply boron to other garden plants. When the back of the flower head turns yellow, it is ready to be cut from the plant.
