How to Plant Snapdragon

Overview

Snapdragons (Antirrhinum majus) are a member of the scrophulariaceae (figwort) family. They are indigenous plants to regions in the Mediterranean and North Africa. They are considered perennial flowers but are usually grown as annuals. They can be grown in all zones and come in tall (36 to 48 inches), medium (18 to 24 inches) and dwarf varieties (6 to 9 inches) and in a variety of colors. The original basic shape of the tubular flowers resembles a dragon's mouth, which gives it its name.

Step 1

Purchase some snapdragon seeds. Or if you have access to some snapdragons that have gone to seed, collect the seeds by clipping off expired buds and turning them upside down over a sheet of white paper.

Step 2

Approximately six to eight weeks before the expected last frost in your growing region, fill up your planting cells with a seed-starting mix. Saturate the soil in each of the planting cells.

Step 3

Sprinkle a few snapdragon seeds (four or five) onto the surface of your moistened seed starting mix. Snapdragons require plenty of light in order to germinate, so push them into the surface of the soil, and do not cover.

Step 4

Mist the surface of each of the cells with your plant sprayer or garden mister, just enough to dampen the soil.

Step 5

Place the planting cells in a light-filled, warm environment. Keep the seeds moist, and check on them frequently, at least once a day. Snapdragon seeds are very minute, and watering from above can displace the seeds. Floridata.com suggests watering your snapdragon seeds from below. Try to maintain the temperature at approximately 60 to 70 degrees with at least eight to 10 hours of light per day. Germination for snapdragons varies but is typically 14 to 21 days.

Step 6

When your snapdragons have reached about 3 inches in height and have several sets of leaves, decide where you want to plant them. Snapdragons can be planted into barrels or other growing containers or in your flower garden. When choosing where you want to plant your snapdragons, consider that snapdragons thrive in full sun, but some varieties are known to grow well in light shade. But all varieties prefer a sandy, or loam-type, soil that is fast draining.

Step 7

Work in 2 to 3 inches of organic matter, such as compost, in the area you plan to plant your snapdragon seedlings by turning the soil over with your garden fork or shovel.

Step 8

Dig holes slightly larger than the diameter and depth of each planting cell. Space each hole at approximately 10 to 12 inches apart in rows about 10 to 12 inches apart. Fill up each hole halfway with water, and proceed after the holes have drained completely free.

Step 9

Extract a snapdragon from a planting cell, forcing it up gently from the bottom of the cell. Remove the snapdragon carefully in order to not damage its roots.

Step 10

Place the snapdragon seedling into one of the holes, making sure to keep it just slightly above (about a half inch) the surface of the surrounding soil. Hold the seedling in one hand while you fill up the hole with soil. Push a planting stake in near each of your snapdragon seedlings, to offer them support as they grow.

Step 11

Water each snapdragon seedling at its base, not from above. The less damp the leaves and stems are, the less likely your snapdragons are to develop rust.
