The Plant Doctor: Bringing amaryllis back to bloom time again

By Harvey D. Goodman

Amaryllis (Hippeastrum hybrida) is probably the most popular, and least understood indoor plant.

Its popularity is tacit and appreciated.

Amaryllis produces a most magnificent cluster of trumpet-like flowers averaging about five or six inches across, suspended on thick stalks producing a floral display of outstanding beauty and envy compared to other blooming houseplants.

Amaryllis belongs to a group of temporary display bulbs, sometimes referred to as flowering pot plants. They are left on display until flowering is over and then moved out of sight.

Some care tips to ensure long lasting blooms and sometimes a second bloom.

Keep the plants in bright light until the flower opens. Once in bloom, move the plant out of direct sunlight and beyond areas where there is excessive heat.

Each stem should produce about four or more flowers. As each bloom fades, snip it off. When all the blooms have faded, snip the stem off about one inch from its base. Don't assume that the show is over. In some cases, the bulb may produce a second stem and more flowers.

For most people, once the Amaryllis loses its flowers, the plant is discarded. What a terrible waste. Amaryllis bulbs have evolved to produce new flowers for many years to come.

You simply have to know how to cater to their particular needs.

Let us begin with the growth season – about one month after the bulb has been planted. During this time of rapid growth the plant should be fed with a regular houseplant food such as Miracle Gro about once a month. Select a pot that is neither too large or too small for the bulb. Most Amaryllis fit comfortably in pots that average between 6-8 inches across. Keep the soil moist, never soggy. Keep the plant in bright light until the blooms are displayed. Over the summer maintain the same routine – indeed it is even advisable to keep the plant outdoors.

In September, bring the plant indoors and stop watering it for 8 weeks. To reflower the bulb, place the bulb (still in the pot) in a dry, cool place or closet for 8-10 weeks. After this period, repot the bulb after gently cleaning old foliage and any old roots. Leave healthy roots intact. The healthy roots will be a creamy white, firm and plump.

When repotting the bulb, leave the “shoulders” of the bulb exposed. The “shoulders” are the top third of the bulb. Select a pot only slightly larger than the bulb itself. Remember, the pot must have drainage holes.

To initiate growth, place the potted bulb in a warm place – about 70 to 75 degrees is best. Water thoroughly to “start up” the growth process. Once growth emerges, water regularly to keep the soil moist and resume the fertilizing.

If you followed these steps, or get close to following most of the steps, you can expect the Amaryllis to bloom again in about eight weeks after the first watering.
