Amaryllis is the houseplant you buy for a show. Grown from a large bulb, it sends up a tall, sturdy stalk topped with trumpet-shaped flowers that can be as wide as your hand, in red, pink, white or orange. It is one of the most popular winter-flowering houseplants, and it is also one of the most forgiving: the bulb stores its own energy, so the plant does a lot of the work itself. This guide covers everything it needs — light, water, soil, feeding, getting it to bloom again, and the common problems that show up when something is off.
What makes amaryllis different from most houseplants is its rhythm. It grows fast, flowers spectacularly, and then rests. After the flowers fade, the strap-like leaves keep working, feeding the bulb for next year's bloom, and then the plant wants a dry rest before it starts again. If you understand that cycle — grow, flower, rest — amaryllis is easy, and a single bulb can flower for many years.

Light
Bright indirect light suits it best, and a little gentle direct sun in the morning is fine too. A spot near an east-facing window is ideal, or a bright windowsill that does not get harsh midday sun. The flower stalk will lean towards the light as it grows, so turn the pot a quarter turn every few days to keep the stalk straight. Once the flowers open, moving the plant a little further from the window can make the blooms last longer.
Too little light is the more common mistake with this plant than too much. Growth slows, stems stretch towards the window, and new leaves come out smaller and less distinctive than they should be. If the plant leans hard in one direction, rotate the pot a quarter turn every couple of weeks so it grows evenly. Our grow-light calculator can help work out how much light your spot actually provides, and the houseplants hub has more plants that suit the same light levels.
Watering
Water weekly; keep soil lightly moist. Push a finger into the soil and only water when the top has dried to the depth the guidance suggests. When you do water, water thoroughly — soak the soil until water runs out of the drainage holes — then empty the saucer so the plant never sits in standing water. Soggy soil is the fastest way to kill most houseplants, and it is far more common than underwatering.
Water less in winter, when growth slows and the soil stays wet longer, and more in summer, when the plant is actively growing. If you are unsure how much water your pot needs, our watering calculator gives a starting point, and our watering schedule generator can help you build a routine. Signs of overwatering include yellowing lower leaves and soft, dark stems; signs of underwatering include drooping leaves and dry, crispy edges.
Humidity and temperature
Amaryllis prefers moderate to high humidity and temperatures of 65–80°F (18–27°C). Most homes sit within that temperature range for most of the year, so temperature is rarely a problem indoors — the things to watch are cold draughts in winter, radiators that dry the air, and cold windows that chill the leaves overnight. Keep the plant away from all three.
Humidity is the factor most people underestimate. In a heated home in winter the air can be much drier than this plant likes, and the first sign is usually brown, crispy leaf edges. A pebble tray under the pot, grouping plants together, or a small humidifier all raise the humidity around the plant. Misting does very little — the water evaporates in minutes. Our humidity and temperature checker can tell you whether your room suits this plant.
Soil and potting
Indoors, this plant needs a free-draining potting mix. Standard potting soil on its own holds too much water and compacts over time, so mix it with perlite and bark to keep air around the roots — the roots need oxygen as much as they need water. A pot with drainage holes is not optional; without one, water has nowhere to go and root rot follows. Our potting-mix calculator can work out the parts for a homemade mix for your pot size.
Choose a pot that fits the root ball with a little room to grow, not a much bigger one. A pot that is too big holds wet soil the roots cannot use, which is one of the most common causes of root rot in houseplants. If you are reusing a pot, wash it first so no old salts or pests carry over.
Repotting
Repot every 1–2 years, or sooner if roots are circling the drainage holes or pushing out of the top of the pot. Move up only one pot size — a pot that is too big holds wet soil the roots cannot use. Spring is the best time to repot, when the plant is about to grow, and fresh mix gives the roots a new supply of air and nutrients. Our repotting calculator can help you work out the next pot size and how much fresh mix you will need.
Feeding
Feed during the growing season, in spring and summer, with a balanced liquid houseplant fertiliser, and do not feed in autumn and winter when the plant is barely growing. Always follow the directions on the label — more fertiliser is not better, and excess salts build up in the soil and burn the roots, which often shows up as brown leaf tips. If you have been feeding heavily, flush the soil with plain water every few months to wash out the salts.
Propagation
Amaryllis is easiest to propagate from the small offsets — baby bulbs — that form beside the mother bulb. When you repot, gently separate offsets that have their own roots and a reasonable size, and pot each one in its own small pot in free-draining mix, with the top of the bulb sitting just above the soil line. Offsets usually take a couple of seasons to reach flowering size, so patience is part of the deal. Growing from seed is possible but slow and the seedlings rarely match the parent, so offsets are the practical route.
Common problems and fixes
| Problem | Likely cause | Fix |
|---|---|---|
| Yellow Leaves | overwatering | See below |
| Brown Leaf Tips | low humidity | See below |
| No Blooms | too little light or plant resting | See below |
Yellow Leaves
Likely cause: overwatering. Let the soil dry more between waterings, check the pot drains freely, and remove the leaf once fully yellow. One yellow old lower leaf is normal ageing; several at once points to watering.
Brown Leaf Tips
Likely cause: low humidity. Raise the humidity around the plant, switch to filtered, distilled or rainwater if your tap water is hard or fluoridated, and flush the soil with plain water occasionally to wash out salts. Trim the brown tips with clean scissors, following the natural shape of the leaf — damaged tips will not heal, but new leaves should come out clean.
No Blooms
Likely cause: too little light or plant resting. Move the plant to brighter indirect light and make sure it is getting its rest period — many flowering houseplants need a cool, drier rest to set buds. Check the feeding routine too: a plant fed too much nitrogen grows leaves at the expense of flowers.
Is amaryllis safe for pets?
According to the data used for this guide, amaryllis is toxic to cats and dogs. Keep the plant out of reach of curious pets, especially if it trails where a cat can reach it, and contact a vet if your pet has eaten any of it.
Frequently asked questions
How often should I water amaryllis?
Water weekly; keep soil lightly moist. Check the soil rather than watering on a calendar: if the top of the soil is still damp, wait. Water thoroughly when it is time, let the excess drain away completely, and never let the plant sit in standing water.
What light does amaryllis need?
It needs bright indirect light. A spot near an east-facing window is ideal, or a bright windowsill that does not get harsh midday sun. The flower stalk will lean towards the light as it grows, so turn the pot a quarter turn every few days to keep the stalk straight. Once the flowers open, moving the plant a little further from the window can make the blooms last longer. Harsh direct sun can scorch the leaves, while too little light leads to slow, stretched growth and a loss of colour or pattern.
Is amaryllis safe for cats and dogs?
According to the data used for this guide, amaryllis is toxic to cats and dogs. Keep it out of reach of pets that chew plants, and if a pet eats any of it, contact your vet.
When should I repot amaryllis?
Repot every 1–2 years, in spring, or sooner if roots are circling the drainage holes. Move up one pot size only and use a fresh, free-draining mix. Our repotting calculator can help with the next pot size.
Can I get my amaryllis to flower again next year?
Yes. After flowering, keep watering and feeding while the leaves are green, then let the bulb rest dry for about eight weeks once the leaves die back. After the rest, repot or top up the soil, resume watering, and a new flower stalk should appear. A bulb that never rests rarely reblooms.
Why is my amaryllis stalk leaning over?
The stalk leans towards the light, which is normal. Turn the pot every few days while it grows to keep it upright, and give the stalk a slim stake if it gets top-heavy with flowers.
