The amaryllis bulb, though large, is one of the easiest bulbs to grow and will normally bloom within 6 to 8 weeks from the time they’re potted.
Planting
Plant bulb without undue delay. If you must delay planting, store in a cool place, 40°F to 50°F. Never expose bulb to temperatures below freezing (0°C or 32°F).
Find a pot at least 2” larger than the diameter of the bulb and bury the bottom 2/3 in potting soil. Choose a potting soil which drains well. You will need room for watering so don’t fill the pot with too much soil. Press firmly around the bulb to be sure that it’s steady but be careful not to damage the roots. Place your potted amaryllis in a light, constantly warm position to encourage growth. As the first floral stalk lengthens, rotate pot through a half turn every day or so. This keeps it from bending towards the strongest light source. If necessary, stake foliage and stalks.
Watering
Soil should be kept only slightly moist - by adding tepid water around the bulb if necessary. Over watering will inhibit root formation - and any water found standing in the saucer should be emptied out. Once the flower stalk is well out of the bulb, water more frequently.
The Amaryllis is a rapid growing plant when developing in warm room temperatures and in direct sunlight. The beautiful flowers last for about two weeks.
Paperwhite Bulbs
Paperwhite bulbs are easy to grow indoors and usually bloom within 4 to 6 weeks after planting. They do not need to be chilled before planting.
Planting
Plant bulbs soon after receiving them. Place them pointed side up in a shallow container with potting soil, gravel, or decorative stones. Cover only the lower half of each bulb, leaving the tops exposed.
If using soil, water lightly after planting. If using stones or gravel, add water until it reaches just below the base of the bulbs. Do not let the bulbs sit directly in water.
Place in a cool, bright spot until roots and shoots begin to grow, then move to a warmer, sunny location. Rotate the container every few days to help stems grow straight.
Watering
Keep soil lightly moist, but not soggy. If growing in stones or gravel, maintain the water level just below the base of the bulbs.
Once in bloom, paperwhites can be moved to a slightly cooler location to help the flowers last longer.
