Cover most bulbs with about 2 inches of soil. Some like the amaryllis and crinum like to have the neck sticking out of the soil. Most grow even if covered with too little or too much soil. Keep the planted containers in a sunny spot. Water when the surface of the soil begins to dry.
Most bulbs start to grow in a week or two.
When you notice the shoots, you can begin feeding the plants every other week with a fertilizer solution mixed according to label instructions. Some bulbs like the amaryllis send up flower stalks about the same time the leaves begin to form. Others grow leaves first and flower a few weeks later. The caladiums are enjoyed for their colorful foliage. Flowers are produced, but they are hidden by the leaves.
