A guide for the care and feed of amaryllis plants

Getting Started
Amaryllis are the perfect flower for growing indoors during the cold weather months. People often ask me how to care for these bulbs so they produce flowers year-after-year. I’ve outlined my process below in five simple steps.I hope you find them helpful.
Five Steps for Successfully Growing Amaryllis
To grow Amaryllis you only need three tools: a garden pot or vase, the growing medium, and one or more amaryllis bulb(s).
- Choosing the right bulb is of utmost importance. Amaryllis come in all kinds of varieties producing various stem lengths and flower colors. So go crazy and pick out a good one. After selecting the variety, bulb size is equally important because the bulb size generally determines how many stems and flowers the bulb will produce. (Bulb size is a measurement of the bulb’s circumference taken at the widest part.)
Longfield Gardens published the below metrics for how many stems and flowers each size bulb is likely to produce:
26/28 cm – 1 stem (occasionally 2) with 3 to 4 flowers
28/30 cm – 1-2 stems with 3-4 flowers per stem
30/32 cm – 2 stems with 4-5 flowers per stem
32/34 cm – 2 stems (occasionally 3) with 4-5 flowers per stem
34/36 cm – 3 stems with 4-5 flowers per stem
2. Growing medium is probably less important for amaryllis. Amaryllis are known to thrive in circumstances of neglect, e.g., in wax housings or glass vases filled with rocks. My preference is to set the bulb on top of organic potting soil. Remember, the bulb should be fully exposed with only 1-2 inches of the base covered by soil or other potting medium. You can cover the soil with moss if you would like to add more interest to the pot.
3. Regarding the container, you can use a glass vase or a 4-6″ garden pot. You don’t need a lot of room unless you are planning to put multiple plants in a single container. (If so, adjust the pot size accordingly.) You may want to stake longer amaryllis stems with, e.g., bamboo, etc. (18-24″ inches tall) and secure with Velcro tape.
4. Amaryllis do not like wet feet, so water only as needed. The soil should feel damp to the touch but not wet. My rule of thumb is to water every 2-3 days with a small amount. If you think you over watered the plant, turn the ceiling fan on to help dry the top soil. Your amaryllis should begin to flower within 2-3 weeks of bringing the plant indoors, with larger bulbs blooming for up to two months.
5. After the flowers are spent, remember to cut the stems down to the bulb to make room for more stems to grow, taking care not to cut the leaves. After all flowers are spent, you should have a plant with long chunky green leaves.
Post Harvest Care
Consider the bulb as a power station for your flowers. Taking care to feed the bulb’s energy needs throughout the year with plenty of sun exposure, the bulb size will increase incrementally and produce even more flowers and thicker /stronger stems for years to come. You can keep your plant going throughout the year by setting the pot in a sunny window indoors and outside in the summer. I generally let my amaryllis go through to October and then cut the leaves down flat against the bulb (removing all plant matter). You can store the bulb in a cool dry place, e.g., in a paper bag, until you are ready to start again. I usually start mine in early December. You don’t need to water the bulbs while they are dormant (in storage).
Happy Growing!
