Crinum is a genus of flowering bulbous perennials native to tropical and subtropical regions around the world. They produce flowers in early summer that can be pink, red or white in color. Crinum bulbs are most commonly planted in pots and grown indoors where their environment can be readily manipulated to suit the plant. They require little care once established and provide a splash of color indoors.
Fill the pot with a a soil mixture made of two parts potting soil to one part organic compost. This mixture will provide optimal fertility and drainage. Form a small hole slightly larger than the crinum bulb in the center of the soil.
Place the crinum bulb directly into the hole with the pointed side facing up. Refill the hole with soil, but allow the tip of the bulb to remain exposed above the soil. Water slightly to dampen the soil and bring moisture into contact with the bulb.
Add a bulb booster fertilizer to the soil after planting to encourage growth. Follow the directions provided by the manufacturer for proper application and dosage.
Spread a thin layer of mulch over the potting soil. Do not cover the tip of the bulb with mulch, as growth may be impeded. Refresh the mulch as needed to keep the layer about 1 inch thick at all times. Set the pot in a window that receives bright sunlight for most of the day.
Water once per week until new growth emerges from the tip of the crinum bulb. Reduce frequency of watering to once every ten days during spring, summer and fall. Apply water once every two weeks during winter.
