Hippeastrum, or giant amaryllis bulbs are sold in fall each year, they are basically a hybrid which has been developed over the years from Hippeastrum species plants. These bulbs are typically planted in pots at Thanksgiving for bloom at Christmas. Bulbs usually produce one or more stout-but-hollow leafless flowering stems (scapes) that grow about 12 to 18 inches tall. You will get 2 to 6 amaryllis flowers, mostly in shades of red, pink and white with interesting spotting and banding that bloom atop each scape. Bloom time is about 5 weeks from when you pot your bulb. Large strap-shaped green leaves begin to grow at about the time the flowers open.

How To Make Your Giant Amaryllis Bulbs, Hippeastrum Thrive

These bulbs should be grown in pots or containers at least 6 to 8 inches wide (there should be about an inch to a half inch distance to the rim from the bulb). Plant each bulb neck up with half of the bulb above the soil surface in a humusy, well-draining potting soil mix. If this comes as a box kit this may be provided for you. Plants enjoy bright locations in the home with some morning sun, but not direct afternoon hot sun. Sun dappled shade or bright shade is best for plants taken outdoors.

Bulbs are commonly planted in pots between mid-fall and late winter, or in succession every week or so during such period for bloom approximately 5 weeks later. Bulbs may also be started indoors in early spring and moved outside for late spring to early summer bloom. Regardless of growing cycle, bulbs need a period of recovery and rejuvenation after bloom when flowers are removed but foliage is left intact and watering is continued, albeit reduced and then a subsequent period of dormancy (about 6 to 8 weeks) before starting the bloom cycle over.
