I bought some beautiful apple blossom, trailing snapdragons this year and am not sure if I should deadhead these flowers or not. If so, where should I cut them? There are blossoms all along the stems.
Deadheading will help keep your snapdragons blooming throughout the summer. Remove the faded flowers just below the flower stem and above a set of healthy leaves. This will keep the new blooms coming. If the plant becomes leggy (long stems and few leaves) prune back further along the stem. This will delay flowering but encourage branching and new growth to help fill in the base of the plant. Don't be discouraged if your snapdragons stop flowering during the extreme heat of summer. As soon as the temperatures cool, they will start blooming again.
