Question: My snapdragons don’t bloom as well as I had expected. What can I do to keep them flowering longer at a time?
Answer: Snapdragons have blooming cycles. They’ll flower beautifully for a few weeks, then they have to regrow and produce new flower buds. Keep the old flower stalks pruned off immediately after they finish blooming, so the plants won’t go to seed. Apply a complete-and-balanced, water-soluble fertilizer with each watering to keep them vigorous. They should bloom three or four times before late spring’s warm weather finishes them off.
