How To Grow Amaryllis

Amaryllis are beautiful houseplants that are easy to grow if given the proper care. We recommend growing in a pot as opposed to soil, as these are indoor plants that can be finicky about temperature. Be sure to choose a pot that has good drainage, and plant using a nutrient-rich potting mix, watering often to keep the soil moist.

Aside from the logistical aspect of growing, you’ll need to be aware of exactly how to care for the flower bulbs. Amaryllis bulbs take a little bit of love and care, especially if you are looking to grow year after year, but the beautiful flowers make it all worth it. 

Caring For Your Amaryllis Bulb

Once you decide to get growing, amaryllis is a relatively low-maintenance houseplant. A rich potting mix, good drainage holes, and regular waterings all contribute to the overall plant health. 

Amaryllis is also interesting in that growers have the option to reuse their bulbs year after year. It may seem like an ambitious project for new plant enthusiasts, but in just a few steps, your amaryllis bulb can be a gift that keeps on giving. 

The Ideal Amaryllis Growing Temperature

Plant bulbs prefer to be kept at a temperature between 70 and 75 degrees. Potted amaryllis should be kept inside for optimal growth in the winter months. If you have left your bulb to grow outside over the summer, be sure to bring it in before the first frost so that it has a long rest period to lie dormant. 

How Much Sun Does Amaryllis Need To Grow?

Flowering Amaryllis

Though amaryllis can tolerate both sun and shade, they definitely will enjoy full sun for at least four hours per day. We recommend setting your pot on a windowsill that provides plenty of light. However, if you see your leaves beginning to turn brown, this can indicate that the plant is burning and may need less sun. 

How Much Water Do Amaryllis Bulbs Need?

To stimulate growth, new flower bulbs need about a cup of water to stimulate growth once they are planted. Oftentimes, bulbs will have a slow start in the beginning. Monitor the plant closely and water in small increments to keep the soil moist. Take care to not flood the soil or overwater  

Pest Prevention

When growing amaryllis, you are going to need to watch out for several kinds of pests, most notably bulb mites and chewing insects such as caterpillars. Overwatering is a leading cause of bulb mites, so take care to keep your plant moisture balanced. And, if you see a caterpillar, remove it with your hands into a bowl of warm, soapy water.

Amaryllis Care Indoors

We recommend growing your amaryllis indoors during the cooler months, typically between around September to around April. 

When growing indoors, place your plant on a sunny windowsill that gets around four hours of light per day. Water regularly to maintain the soil moisture, and be sure to give support to any stalks that are struggling to hold the weight of their flower. 

Amaryllis Care Outdoors

If you are interested in growing your amaryllis outside, do so in the summer. Pick an area that gets partial sunlight (no more than four hours of direct sun) and water it often to keep the soil moist. Bring the bulb back inside before the first frost in the early fall. 

What Is Amaryllis’ Flowering Period?

Amaryllis can flower anytime between December and June, depending on the temperature and grower preferences. The flowering period lasts between seven and ten weeks.

How To Reuse Your Amaryllis Bulb

If you are looking to reuse your amaryllis bulbs, once the flowering period has ended, be sure the cut the flower stems to about a half-inch above the top of the bulb. Take care to cut only the stem and not the green leaves that surround it; those will help your plant get the nutrients it needs. 

After cutting the stems, move your container to sunny place indoors, watering regularly to keep the soil moist. When the weather begins to warm, you can move the container to a sunny location in your garden for the summer months. Make sure it is getting plenty of water, but do not overwater and make it soggy. 

During the early fall, before the day of the first frost, bring the plant back inside and snip all foliage to about an inch above the bulb. You’ll then want to stop watering, and store it in a dry, dark place (like a basement) so that the bulb can go dormant. 

How To Make Amaryllis Bulbs Rebloom

After the bulbs have gone through a dormant period of about ten to twelve weeks, it’s time to replant! Whenever you’re ready, complete the same steps that you did the year before, planting in nutrient-dense potting mix, stimulating the bulb with about a cup of water, and getting your plant lots of sunlight. 

Grow Pro Tips For Amaryllis

Here are some of our experts’ best tips for growing amaryllis bulbs: 

1. Location, location, location. Be sure that your plant has a good amount of sunlight to ensure that it thrives but not too much so that it burns. 

2. Pick the right container. You really want something that has good drainage holes in it to ensure your amaryllis plant gets the moisture that it needs. 

3. Give support. Amaryllis blooms can grow pretty tall. If you see your stems start to droop from the weight of their flowers, tie it to a bamboo splint or another sturdy pole. 

4. Plan ahead. If you are looking to reuse your bulbs year after year, create a timeline of when each step of the process needs to happen. This is especially true when timing dormancy and reblooming periods in early fall and winter. 

5. Share the love! Amaryllis are an amazing hostess or Christmas gift. Share a plant–and your new found growing advice–with someone you love.
