Bulbs in the Landscape

Spring bulbs will soon fade, and the foliage of hardy summer bulbs will start to emerge. Even though it may be tempting, do not remove foliage from the faded spring bulbs that have past their prime. These leaves are necessary for photosynthesis to occur which will produce carbohydrates to be stored in the bulb for next year’s flower production. Do, however, remove old blooms from the spring bulbs; this will allow the plant to send energy toward rebuilding the bulb instead of producing seeds.

Once the fear of frost has past, hardy summer bulbs, such as dahlias, lilies, cannas, and gladiolus, can be planted. This is typically around April 15th in the upstate, but watch the forecast in your region for a better estimation. Select a planting location with well-drained soil and the amount of sun or shade best for the bulb species. For more information, see HGIC 1155, Spring-Flowering Bulbs, and HGIC 1156, Summer- and Fall- Flowering Bulbs.
