Planting your bulb
You may grow your bulb in a small pot about 4-5 inches (10-13 cm) wide and tall. The pot must have drainage holes.
Use a well-draining soil mix, such as 2 parts potting soil to 1 part perlite (use small- or medium-size perlite, not large chunks) or coarse sand. Or you may use equal parts of coco fiber and perlite, with some slow-release fertilizer mixed in.
Bury the bulb so the top of it (which is the pointier end) is about 1/2 inch (2 cm) below the surface. Add just enough water until the soil is lightly moist throughout, and keep it this moist until it sprouts. Don't fully saturate the soil.
Until it sprouts, try to keep it between about 65 and 80 degrees F (18-27°C) during the day (a little cooler at night is ok).
The bulb may take anywhere from 2 weeks to 3 months to sprout, depending on when it went dormant. Once it sprouts, keep the soil evenly moist (don't let it dry out, nor stay constantly saturated).
Give it bright light, but shade it from strong afternoon sun. It does not need much direct sunlight to thrive - just bright light (See: "Growing indoors with LED lights").
Feed it about every 3 months with a general-purpose fertilizer that contains micronutrients. Follow the dosage on the package.
The bulb eventually goes dormant for 2 or 3 months, and when it does, reduce the watering until the soil slightly moist (not fully dry) and at the temperature range mentioned earlier until it emerges from dormancy. If you wish, you may separate any baby bulbs that have emerged, while the plants are dormant.
Pests to watch for -- Mealybugs may attack the bulbs (look for cottony growth where the leaves emerge from the ground). To control mealybugs, try using an insecticidal soap soil drench.
Have fun growing it!
