Water snapdragons often to keep them blooming. Water them from the ground, because wetting the foliage can sometimes cause mildew and rust. Keep the area around the plants clean, and don't let plant matter and debris pile up.

Feed snapdragons regularly throughout the growing season to keep them blooming. Use a balanced water-soluble fertilizer, applied according to the manufacturer's directions.

Stake tall varieties of snapdragons to keep them growing upright in windy conditions. Drive the stake into the ground carefully, and connect the snapdragons to the stake with a piece of soft twine. Shorter varieties have sturdy stalks and require no staking.
