Information About Amaryllis
Amaryllis, or Hippeastrum, are native to South Africa where, interestingly enough, they usually bloom in early spring. Depending on the type, they can reach 12-24″ tall.
Since it’s so easy to control the bloom time and grow them indoors, they became a popular Christmas flower.
They’re sometimes called a lily because of how they look, but are actually from the Amaryllidaceae family, and not even related to lilies.
Different Types Of Amaryllis
There are hundreds of different types of amaryllis on the market these days, so you’ll have plenty to choose from.
Though red and white are the most common colors, they can be any shade of red, pink, or white. Some are even striped or multi-colored.
The size and shape of the flowers can be different depending on the variety too. Some are rounded, while others are star-shaped, and they can have either single or double petals.
A few of my favorites are ‘Apple Blossom’, ‘Clown’, ‘Splash’, ‘Red Lion’, and ‘Christmas Gift’.
The prized amaryllis flowers grow on top of thick stems, and there can be 2-6 blossoms per stalk. Each bulb can produce 1-3 stalks per season.
The natural bloom time varies by variety, and it can be anywhere from late winter through summer. Though most people force them to bloom during the early winter months.
The flowers get larger and more spectacular with age. They usually only flower once per year, though some can give you a surprise second bloom in the perfect conditions.
Unfortunately all parts of the amaryllis plant are toxic, so you should be careful where you grow them if you have pets.
The ASPCA.org website has them listed as being poisonous to both cats and dogs. So keep them out of reach of your pets (and the kiddos too) at all times if you’re concerned.
How To Care For An Amaryllis
The first step in successful amaryllis plant care is choosing the right location to grow them. Before you can do that, it’s important to understand what they need.
Even though it’s most common to find amaryllis for sale during the fall and winter, they are actually tender perennials that can’t handle the cold.
They will survive in zones 10 and above for sure. But there are a few hardy garden varieties that can survive down to zones 6 or 7.
If you live in a colder area, then you must bring them indoors during the winter. Otherwise, make sure you know the hardiness of the variety you have before planting it in your garden.
Where To Grow Amaryllis
If you live in a warm enough climate, you can grow them in your garden year round (lucky you!). Otherwise, you must keep them indoors through the winter.
Most people put them outside during the summer, and then bring them back inside in the fall.
Wherever you choose to grow them, they need fast-draining soil and a spot where they get lots of bright sunlight.

Amaryllis Plant Care & Growing Instructions
Now that you know where to grow them, let’s dive into the details of how to care for your amaryllis. These tips will ensure you’ll be able to keep yours thriving.
One of the most common problems people have with caring for an amaryllis is overwatering.
When they are kept consistently wet it will cause the bulb to rot, which will ultimately kill the plant.
They like to dry out between soakings, so pour water over the top until it starts coming out of the drainage holes. Then be sure to dump out all of the excess so they are never soaking in it.
If you struggle with giving them the right amount, I recommend getting an inexpensive moisture gauge to help you out.
It’s very important that your amaryllis gets enough sunlight, otherwise they can grow tall and leggy. They need full exposure, but will tolerate partial shade outdoors.
For leggy flowers, use a stem stake to support them so they don’t fall over. You can also rotate the pot every few days to help keep them growing straight.
Regular feedings are must as a regular part your amaryllis care routine. They need lots of nutrients in order to grow and bloom their best.
Begin fertilizing when it’s done blooming, and continue feeding through the summer. Stop in the fall, and don’t fertilize at all during dormancy or flowering.
They aren’t super fussy about the type of soil, as long as it has good drainage. A general purpose mix will work just fine for growing amaryllis.
The ideal temperature for growing amaryllis is between 65-80°F. But that range should vary depending on the time of the year.
When they’re blooming, it’s best to keep them cooler, between 55-65°F to make the flowers last longer. In the summer it should be between 70-80°F to help them grow faster.
During dormancy, the temperature should stay between 45-55°F to let it rest, and keep it from prematurely sprouting.
Contrary to what you may have heard, you don’t need to repot amaryllis every year as part of their regular care. They actually prefer to be pot-bound.
The bulbs only need to repotted every few years at most, or if they have outgrown their container.
When it’s time to size them up, the best time to do it is the spring or after they’re done blooming. Choose a pot that’s 1-2″ larger and has drainage holes in the bottom.

Healthy amaryllis plants rarely have problems with pests, but mealybugs and fungus gnats can sometimes become a problem.
Fungus gnats are a sign that you are overwatering. To get rid of them, allow the soil to dry out more.
Neem oil works great to naturally kill bugs on the leaves and stems, and has a residual effect to keep them away.
The good news is that you don’t have to worry too much about pruning as part of your regular amaryllis care routine.
It’s ok to trim any damaged leaves to keep the plant looking nice, but never completely remove any of the green or yellowing leaves.
They need to stay on as long as possible so the bulb can regenerate energy to bloom again next year. Wait until they shrivel and turn brown to cut them off.
In their natural habitat, amaryllis bulbs go dormant during the cooler winter months. If you want them to flower reliably every year, it’s best to mimic this habit, rather than keep them growing year round.
They normally go dormant when the temps cool down in the fall or early winter. When this happens, the leaves will start to turn yellow, then eventually shrivel and die back completely.
The beauty of them is that it’s very easy for force dormancy and control the timing of the blooms, which is what most people like to do.
Amaryllis Propagation Tips
Dividing amaryllis bulbs is the easiest and most common method of propagation, but they can also be grown from seeds.
Mature bulbs will form offshoots around the base, which can be removed and planted into their own containers.
Seeds will take much longer to produce a sizable plant, and it will be a few years before they are large enough to flower.

Troubleshooting Common Amaryllis Problems
Once you get the hang of it, you’ll find that taking care of an amaryllis is pretty easy. But it can be very frustrating when yours starts having issues, and you don’t know why. My tips below will help you figure it out.
Amaryllis Not Flowering
There are a few reasons why an amaryllis will not flower. Most likely it’s because the bulb hasn’t built up sufficient energy.
This can happen when the leaves are cut off too early, from a lack or light or fertilizer, or the bulb is simply not mature enough.
Make sure they get plenty of full sun, fertilize them regularly from spring through summer, and never cut off the green leaves (unless of course you’re trying to force dormancy).
Droopy amaryllis leaves could be caused by over or under watering, or not enough light.
Inspect the bulb to make sure it’s not rotting, then check the moisture level of the soil. If watering isn’t the issue, then give your plant more light.
Flowers Falling Over
Since the blossoms are so large, sometimes they can fall over once they open. The main problem is usually lack of light, which causes the stem to grow long, tall, and thin.
Leaves Turning Yellow
It’s normal for the leaves to turn yellow as the plant starts to go into dormancy (usually in the fall).
However, if your amaryllis gets yellow leaves during its active growing season, then it could be caused by overwatering or bulb rot.
