How to Take Care of Snapdragons

Snapdragons are available in sizes from less than a foot high up to about 3 feet tall. Their flowers come in all colors, except blue. Snapdragons bloom until hot summer weather sets in, and then they fade. Rather than pulling your snapdragons out, cut them back and water them. When fall's cooler temperatures arrive, your snapdragons will bloom again.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

  • Garden trowel Granulated fertilizer
  1. 1

    Choose a site for your snapdragons that is in full sun. They're not heavy feeders, and grow well in average garden soil. Rake the soil smooth and remove large rocks or stones.

  2. 2

    Plant transplants 6 to 8 inches apart in the spring, about the time of your last frost.

  3. 3

    Water regularly and remove weeds as they appear.

  4. 4

    Cut the plants down to about 5 inches high when hot summer weather arrives and the plants stop blooming. Water well and feed with an all-purpose granulated fertilizer according to the manufacturer's recommendations.

  5. 5

    When cool fall weather arrives, pinch off the faded blooms, one by one. They will bloom for several weeks, until killed by frost.

Tips & Warnings

  • If you want your snapdragons to reseed themselves, leave one or two plants uncut to form seeds when you cut the others down in the heat of summer.
  • Snapdragons are mildly toxic if ingested; keep away from children, or provide adequate supervision.
