Part 1 Germinating Sunflower Seeds
- Check the outdoor temperatures. While sunflowers can be started indoors, they work best if they're started in the ground.
- Select a sunflower variety.
- Fold the seeds in a damp paper towel.
- Keep the paper towels in a plastic bag.
- Clip the edge of the seed shells (if necessary).
Simply so, do sunflowers grow back after you cut them?
Cutting off a sunflower (Helianthus spp.) bloom can serve several purposes, depending on the type of sunflower you grow. With annual varieties, the only reasons to cut off the dead blooms is to harvest the seeds. But perennials can grow new blooms if deadheaded, in addition to providing you with seeds.
How do sunflowers regrow?
In sandy soil, 2 inches deep is better. Cover and keep watered until seeds sprout in 7 to 10 days. When first true leaves appear (the second set of leaves); thin plants to about 2 feet apart. Depending on the variety, sunflowers will mature and develop seeds in 80 to 120 days.
Can you cut back sunflowers?
Pruning Sunflowers. Perennial sunflower stalks are pruned in spring before they begin to bud; avoid pruning annuals, which can kill them. Perennial stems can be reduced by half or more in late spring or early summer to reduce the mature flower's height and avoid the need for staking.
