Planting summer-blooming bulbs


Most summer-bloomers, such as gladioli, calla lilies, dahlias, tuberous begonias, and crocosmias, love warm soil and toasty summer sun. If you garden in a mild climate (Zones 8 to 10), you can plant these bulbs in the early spring and expect flowers by summer. If you garden in a colder area, early spring planting isn’t feasible. Instead, wait until late spring or early summer — the same time locals plant tomatoes outside — or start bulbs early indoors in a warm spot and care for them until danger of frost has passed; then you can move the plants outdoors. In either case, regular doses of all-purpose fertilizer (applied according to label directions) can nudge your plants into faster, more robust growth and more and better flowers.
To get flowers earlier and longer from these summer bloomers, visit a nursery in late spring or early summer (or place your order then with a mail-order house, either via catalog or Web site) and buy a larger, pre-started plant.
