Amaryllis is a striking winter-blooming plant that produces large red, pink or white blossoms on 18 to 36-inch flower stalks in midwinter. The flower stalk produces four or more blooms that may be bicolored with a white or pink center on each petal. Amaryllis is often sold as a bulb that you can pot up in November to have blooms by Christmas. They are easy to pot and require minimal care once they are up and growing.
Choose large bulbs with no signs of rot or disease. Look for bulbs that are firm and smooth with no soft spots.
Use pots that are no more than 2 inches wider than the circumference of the bulbs. Use pots with predrilled drainage holes in the bottom.
Place 1 to 2 inches of potting soil in the bottom of each pot. Set each amaryllis bulb on top of the soil with the root side facing down and the stem end up.
Fill in around the bulbs with potting soil, gently firming it with your hands as you fill. The soil level should come two-thirds of the way up the bulb, leaving the upper third above the surface.
Water the soil with lukewarm water until it is moist throughout. Allow the soil to begin to dry between waterings.
Once new growth appears in the stem area, place the potted amaryllis bulbs on a sunny windowsill away from drafts. Water whenever the soil surface begins to feel dry.
Fertilize with water-soluble houseplant food every two to four weeks while the plant is actively growing. Blooming will occur within six to eight weeks after planting the bulbs.
