• Bulbs should be planted about 2/3 way down in soil, with top third showing above the soil (or 1/3 of the way down if you're planting in small rocks).
• Don't overwater paperwhites or bulbs can rot.
• Never let the water rise above the bottom of the bulbs.
• Water amaryllis very infrequently until they start to grow.
• Pack soil firmly at the surface to prevent bulbs from lifting out of the container.
• If bulbs start to fall over, either loosely tie a string around all of them--about 1/3 of the way up from the bottom--or place sticks around them and tie a string around the sticks.
• Don't worry about crowding bulbs--they like to be smooshed closely together.
