Most forced spring-flowering bulbs should be discarded after flowering. Maintain high humidity around the plant and keep the soil uniformly moist. High temperature and low light intensity will result in flower bud drop. Gardenias decline rapidly after flowering and should be discarded. Geraniums - Potted geraniums are typically available March through June.
Many new types are available, including vining and hanging basket cultivars.
Bright light is essential to keep geraniums flowering. Geraniums respond favorably to having the soil dry out between waterings. Keep them in pots or transplant into the landscape once the danger of frost has passed. They are not winter hardy and must be brought indoors before frost if you wish to over winter them. Keep the soil uniformly moist.
