Amaryllis are one of the most amazing flowers. Some of my readers from warmer climates can grow these beauties outdoors, but in non-tropical climates, Amaryllis are grown indoors. The bulbs are big, chunky bulbs and are a popular Christmas flower. Often they are packaged in pretty boxes for gift giving. Follow along today as I share How to Grow Amaryllis Bulbs Indoors.
Amaryllis bulbs are marketed as Christmas flowers, but I don’t plant mine until after the holidays. I don’t have room to get bulbs going with all the Christmas décor. Plus, I love picking up the bulbs on clearance and then having them bloom in February and March when I’m sick of winter gloom. There’s nothing more cheery to me than the big, bright blooms of amaryllis flowers in the dead of winter. If you have more than one bulb, it’s fun to stagger out the plantings, so you have several weeks of Amaryllis blooms.

Supplies for Growing Amaryllis Indoors
- Amaryllis Bulb – the bigger the bulb, the more blooms you’ll get (see my picks below)
- Potting Mix – I’m going to try these this year.
- Container with drainage holes and a saucer – use a heavy pot, so it doesn’t tip as the amaryllis grows and becomes top heavy
- Water and Fertilizer
This is my favorite amaryllis ever. It was stunning! The best part… I purchased this bulb on clearance at WalMart after Christmas for $5. This one was top heavy and hard to keep upright.
How to Plant Amaryllis Bulbs
According to the internet, there are about 155 different ways to get your Amaryllis bulbs growing (said in jest), but I will just stick with what works for me.
- Fill your container with new potting mix only about a third to half full.
- Set your bulb in the pot on top of the potting mix like the picture below.
- Add more soil and tamp it down a bit until about 1/3 of the bulb is still showing above the top of the potting mix.
- Sit the pot in the sink and thoroughly water (add fertilizer at this time). Allow the water to drain completely.
- As the soil settles in around the roots after watering, you may need to add a little more soil. Remember to leave 1/3 to 1/2 of the bulb above the soil.
- Be sure to set your pot on a saucer to catch water runoff.
- Place in a sunny window.
It’s so exciting to see the green tips start emerging from the bulb. In my experience, it usually takes 6 – 8 weeks before the blooms start.

How to Care For Your Amaryllis
- Water the plant when the top inch or so of the soil feels dry.
- Each time you water allow the plant to drain completely and then empty the saucer.
- Don’t forget to turn your pot, so the stem grows straight.
- To lengthen the bloom time, once your Amaryllis starts blooming, move it out of direct sunlight.
- Amaryllis can get very top heavy, especially those with double blooms, so they will need to be staked. These stakes are made especially for Amaryllis and don’t detract from the beauty of the plant. I recommend adding the stakes when you plant your bulb, so that you don’t puncture the bulb with the stake.
Determining the Bloom Time of Amaryllis
There’s no guaranteed way to determine the bloom time of Amaryllis. In my experience it usually takes anywhere from six to eight weeks (sometimes less, sometimes more) from the time the bulb is planted until it blooms. Here is a handy chart I put together to make estimating the time easier. So, if you want you Amaryllis to bloom in time for Christmas, the bulb should be planted somewhere around November 1st.

How to Grow Amaryllis Indoors in Water
- Fill a Glass, Cylinder Vase (the Amaryllis can get quite top heavy as it grows, so the vase needs to be at least 10-12 inches tall) with 2 – 3 inches of pea gravel
- Place the Amaryllis bulb (root side down) on top of the gravel.
- Add some more gravel to help support the bulb, but don’t bury it.
- Add water to the vase so the the roots are touching it, but the bulb is not submerged at all. If the bulb sits in water it will rot.
- Watch the water level carefully and add just a little at a time.
What to Do With Your Amaryllis Bulb After It’s Bloomed
Amaryllis bulbs can be spendy, so it’s awesome to be able to grow Amaryllis flowers for years from the same bulb. Once you’ve learned how to grow Amaryllis indoors, now what do you do after they’ve finished blooming.
- When the flowers have faded, cut them off so they don’t form seeds which will zap energy from the bulb.
- Leave the flower stalk until it turns yellow.
- The green stems will continue to supply energy to the bulb, so don’t cut those off.
- Move the plant back to a sunny window and allow it to continue to grow.
- Continue to water and fertilize.
- In the Spring, when all danger of frost has past, you can move your Amaryllis plant outdoors.
- Acclimate it to the outdoors just like you would any other plant. Starting off in shade and then moving it to full sun.
- Again continue to water and fertilize your Amaryllis plant all summer long.
- Bring the plant back inside before the first frost.
This year, my amaryllis bulbs got a summer vacation in the vegetable garden. Don’t they look happy.
I’m amazed at how big the bulbs grew on their summer vacation. This was the first time I actually planted the bulbs in the ground. It will be exciting to see how many blooms these big babies produce.
Amaryllis bulbs don’t really have to have a period of dormancy in order to bloom. But, if you want them to bloom at a certain time, a period of dormancy is necessary to force them to bloom when you want them to. I put my plants or bulbs in the dark basement (the creepy part of the basement) and leave them to go dormant with no light or water for about 2 – 3 months. Then, I bring them out of dormancy about 8 weeks before I want them to bloom. So for me that’s somewhere between January 1st and January 15th. And, the process starts all over again.
