Bloom Length of the Amaryllis

Amaryllis are among the easiest to grow and showiest of indoor bulbs. Many factors influence how long they will bloom for you, but in general you can expect a six-to-eight-week show of color.
  1. Factors of Bloom Time

    • The more light, water and food you give your amaryllis, the longer it will bloom.

      Many factors influence how long an individual amaryllis will bloom. How much light, water and fertilizer each amaryllis receives dictates just how long it will bloom. Age is a factor, as well. The older the bulb, typically the more floriferous it will be.

    Prolonging Amaryllis Blooms

    • Keep your amaryllis blooming for longer periods by moving it to a cooler location.

      Once your amaryllis starts blooming, you can prolong the length of bloom by moving it to a cooler location. A spot between 55 degrees and 65 degrees F. will keep your amaryllis blooming longer. The cooler air slows down the senescence of the flower.

    Forcing Rebloom

    • After your amaryllis has stopped blooming, you can force it to rebloom by withholding water and nutrients for several weeks.

      After the initial bloom, you can encourage your amaryllis to rebloom. Cease all watering and fertilizing for eight to 10 weeks post-bloom. Remove the leaves and stalk as they wither and die. Once you see new growth, repot the bulb into a slightly larger container and resume watering and fertilizing as before.
