Growing Info

Direct seed (recommended) - After last frost, sow 1/2" deep. Transplant - Sow into 72 to 50-cell flats 2-3 weeks prior to planting out. Plants dislike root disturbance, but sowing indoors and then transplanting the first crop outdoors can be a successful way to get first-early sunflowers. Do not pinch plants. Pinched single-stem sunflowers will produce low-quality blooms or no blooms at all. Succession-sow every 1-2 weeks and/or plant multiple varieties with varied days to maturity for continuous harvest.
