How to Grow Climbing Snapdragon


Climbing snapdragons are flowering vines that are perennials, but are often grown as annuals for use in hanging baskets. They can grow and twine on trellises, walls and fences, or they can grow wide as a ground covering. Climbing snapdragons grow in USDA zones 9 and 10, and require full sun or partial shade.

Step 1

Plant snapdragon seeds in a sunny area outdoors in all-year warm climates. Scatter the seeds and water well. Keep the ground moist for several weeks. Alternatively, plant seeds indoors in a small planting tray with all-purpose potting soil. Scatter the seeds, water lightly, cover them loosely with plastic wrap and place in the sun. It will take between 8 and 12 weeks before you can move the climbing snapdragons outdoors, so plant them indoors 8 to 12 weeks before the last frost.

Step 2

Dig holes as deep as the root and several inches wide. Plant multiple climbing snapdragons about 6 feet apart. They will grow to fill in the gaps over the next few seasons. If planting in a hanging basket, plant several snapdragons together in one pot.

Step 3

Thin the snapdragons out, as necessary, as the vines may naturally multiply. If you planted seeds outdoors, thin them out after the seedlings begin to grow so there is one plant per 6 feet.

Step 4

Water periodically, especially during dry spells in the warmer months.
