Patience is a virtue it is said. That is one virtue some of us lack when it comes to growing amaryllis flowers. Fortunately, we can trick the bulbs into thinking it is time to flower. There are some schools of thought that say forcing amaryllis bulbs in soil versus water is the best method. Here are some tips on how to force amaryllis bulbs in soil for a successful project that will brighten your home and your mood.

How to Force Amaryllis Bulbs in Soil

Purchased forced bulbs allow you to enjoy flowers earlier than they are produced in nature. This jump start on spring can brighten the dark spaces in the winter home. Amaryllis forcing indoors is easy and allows you to watch the tall stems grow right before your eyes. Take a do-it-yourself approach and try amaryllis bulb forcing. Kits are available readily or you can force the previous season’s bulb, provided you kept it in a dry location.

The first step is to make sure you have healthy bulbs. Choose large bulbs without blemish or mold. If you stored them from the previous year and they got moist, rot may have set in and these should be discarded. Forcing amaryllis bulbs in soil is best since it minimizes the chances of any rot forming on the bulb. Some people force amaryllis in water, but if your home is humid or the bulb is too low in the water, fungal damage can occur.

The next step is choosing the proper container. The bulbs don’t need a large pot in spite of their massive blooms and tall stems. Pick one that drains well and is about 1 or 2 inches wider than the diameter of the bulb. Planting the bulb at the proper depth comes next.

Fill the bottom of the pot with a couple of inches of soil. Situate the bulb about midway in the container and fill up to the top with soil. The bulb should have the top third sticking out of the soil when you are finished. Push in a bamboo or other type stake just to the side of the bulb. This will help support those leggy leaves and stem when the growth becomes tall.

Water the soil well, ensuring excess moisture is draining from the bottom. A key to amaryllis forcing indoors is temperature. Best, most rapid growth will occur if the container is in a room that is at least 70 degrees Fahrenheit (21 C.).

Do not water the container again until you see green growth. Provide bright indirect light and evenly moist (not soggy) soil once the leaves have begun to appear.

Amaryllis Bulb Forcing Care

It might seem that faster growth would occur with a little plant food but hold your horses. Wait until you see green. It can take anywhere from 2 to 8 weeks for growth to appear. You can try to stimulate the bulb by placing it on a warming mat. Then fertilize with a diluted (by half) water soluble food every 2 to 3 weeks.

Rotate the pot every few days as growth continues to keep the stalk straight. Depending upon the variety of amaryllis, blooming should take place 6 to 8 weeks after potting. Once the flowers appear, move the plant to a location with indirect light to prolong the blooms.

Amaryllis bulb forcing in soil is one of those no brainers once you have a few tricks up your sleeve. In no time you will be face to face with one of the most brilliant flowers available.
