How to Grow and Care

Snapdragons will bloom most profusely in full sun to partial shade in the spring. Once the temperature heats up, they may stop blooming altogether. Planting them in partial shade and keeping them well watered will help them make it through the summer to begin blooming again in fall.

Regular deadheading will keep your Snapdragons blooming longer. They won't need much care early in spring, but mulching to keep the soil cool and moist can help them handle summer better.

Some of the taller varieties will need staking unless they are planted close enough to other plants to lean on them.

Snapdragons are tender perennials and may die off in colder climates. If they do survive the winter, prune them back by about 1/3 to encourage new growth. Don't be too disappointed if they don't last long. Snapdragons tend to go downhill after their first year, and it's best to start fresh every year. Many varieties will self-seed and come back on their own, although they won't always look like the original plants you planted. See more at: How to Grow and Care for Snapdragons.
