How to Grow Snapdragons Inside
Snapdragons are a common, bright resident of many flower gardens. Thriving in full sun, snapdragons prefer slightly cooler soil and may suffer if the soil they grow in becomes too warm. If you have a sunny window indoors, plant a dwarf snapdragon plant in a container and you may soon see steady growth and prolific blooms from a beautiful snapdragon plant.
Fill the container approximate three-quarters full with potting soil. Remove a snapdragon seedling from the temporary plastic pot and place it into the center of the container. Situate the snapdragon so it will be growing at the same depth as it was in the temporary pot. Add more potting soil around the roots of the snapdragon and pat the soil down firmly with your hands.
Water the newly-planted snapdragon plant generously. Place the plant in a location that receives direct sunlight for at least four hours each day. Provide enough water for the snapdragon plant so that it does not dry out between watering. Do not saturate the soil so much that it's soggy.
Remove the top third of all stems with pruning shears after the snapdragon plant has acclimated to the container and is growing well. This will encourage the snapdragon plant to put forth new and bushy growth.
Fertilize the snapdragon plant by mixing the fertilizer with water according to package recommendations. Add the fertilizer around the base of the plant, being careful not to splash fertilizer onto the foliage. Fertilize approximately once per month.
Prune the snapdragon plant immediately after it finishes blooming for the first time. Cut back all of the stems to approximately 6 inches long and fertilize the snapdragon again. The snapdragon will likely bloom a second time.
Grow Snapdragons In A Pot
Fill peat pots with a soilless seed-starting medium the night before you intend to plant your snapdragon seeds. Soak the medium thoroughly and allow it to drain several times, until the seed-starting medium is a dark brown color and moist to the touch. Move the pots into a room that is 60 to 70 degrees and allow them to come to room temperature overnight. Scatter a few snapdragon seeds in the center of each peat pot, lightly pressing them into the medium with your fingers. Monitor the seeds carefully over the next 10 to 14 days. Fill a large, well-draining pot with enough potting soil to reach within 2 inches of the rim. Water the pot thoroughly and place in a protected, shaded outdoor location. Remove fading flower spikes to encourage continual flowering. Allow the plants to die back when summer temperatures rise, but continue watering them if they remain green -- your snapdragons may begin blooming again as fall approaches.
