Giant Sunflower Growing Instructions Print

Giant Sunflower

Be sure that the last freeze date for your area has passed and that the soil is soft and warm. If you're starting seedlings indoors to transplant, you can start them about 2 to 3 weeks prior to your area's last frost date. Sow the whole seed 2 cm deep. It needs at least 20 degrees Celsius.
Your sunflowers will appreciate at least 6 hours of sunlight per day for their best growth, and will point their heads toward the sun regardless of where you plant them.
