Cultivation Methods for Scilla rupestris Van der Merwe
Scilla rupestris Van der Merwe, commonly known as rock scilla, is a beautiful flowering plant that is easy to cultivate and care for. This plant prefers well-drained soil and full sun to partial shade. It can be propagated through seed or division of bulbs.
The ideal time for planting Scilla rupestris is in the fall, just before the onset of winter. The bulbs should be planted at a depth of 3-4 inches and spaced about 4 inches apart. When planting in groups, keep about 8-10 inches between each group to allow the plants to spread out.
Watering Needs for Scilla rupestris Van der Merwe
Scilla rupestris Van der Merwe needs moist soil for proper growth and bloom. However, it is important not to overwater the plant as it is susceptible to root rot. Watering should be done regularly but moderately.
