crinum

Water crinum plants deeply but infrequently to encourage strong, healthy root growth. Aim to water the plant deeply once a week or every 10 days in the summer months and every 2 to 3 weeks during cooler times of year. However, adjust this schedule as needed, according to the weather and soil conditions. If the soil is light and well-drained, for example, the plant may need more frequent watering. Consider adding a layer of mulch around the base of the plant to help insulate the soil and conserve soil moisture.

Crinum bulbispermum requires full sun exposure of at least 6 hours per day. For optimal plant health and growth, the best location is a sunny, well-ventilated spot with indirect sunlight from morning till evening. The plant should be placed out of direct sunlight during the hottest part of the day, such as midday. During spring and summer when days are bright, the crinum bulbispermum will enjoy plenty of sunlight and may even be fine with more than 6 hours of direct sunlight per day. In the late summer and winter, plants may benefit from less direct sunlight, although still plenty of light for growth.

Pruning for Crinum (Crinum bulbispermum) should be done once a year, in late winter or early spring. It is best to prune just as the new growth is emerging. Trim off the old, dried flowers and foliage to encourage new growth. Cut as far back as you are comfortable, but do not prune more than 1-third of the plant at a time. Doing so risks leaving too few leaves to support the plant's bloom. Remove any dead or damaged leaves or stems at the base of the plant. Remove dead or diseased flowers to keep the plant healthy.
