   Amaryllis: Year Round Care
 



When Hippeastrum bulbs have finished flowering, many people throw them out because they consider the plant to be awkward and ugly looking. If you fall into this category, make sure your bulb is finished flowering first. Sometimes they can finish with one flower stalk, then shoot up another one three weeks later. As these bulbs are rather expensive, you want to make sure you get the most bang for your buck.

For those of you too soft-hearted to throw out a living plant, no matter how ungainly it looks, I have good news. You can get your Hippeastrum to flower for many years to come, and it will often create baby bulbs that will eventually flower like their parent bulbs.

Usually, when your bulb is finished flowering, it will begin to produce long, strap-like leaves. It's best to move it outside in the summer, if your growing season is short. It must gather enough energy inside its bulb to flower again the next winter. Direct sun all day outside may burn the leaves, so try a partially shaded spot at first. Hippeastrum can be planted directly into your garden for an interesting shape and contrast, but be sure to leave a third of the bulb above ground, and be careful to avoid wet conditions. You can fertilize throughout the summer, after the plant has grown leaves. Use a regular houseplant fertilizer at about half the dosage recommended on the container.

By September, Hippeastrum should begin its rest period, so stop fertilizing, water less frequently, then stop altogether. If your bulb is planted in the garden, you will need to lift it out to protect it from the rain. Allow the leaves to turn yellow and then cut them off. Keep the bulb dry and cool for six to 12 weeks. Most people place their resting bulbs in the basement or garage. The ideal temperature for this rest period is between 45°F (7°C) and 59°F (15°C). You may leave your bulb in its pot (as long as the soil is dry) or pack the loose bulb in wood shavings or dry peat. Don't put your bulb in the fridge, as this can cause it to dry out.

When the rest period is finished, bring the bulb out, give it a light watering and put it back in its sunny windowsill to start the cycle over again.
