Pick a Good Bulb

Choose a bulb that feels solid and healthy. Bigger bulbs usually mean more flower stalks. Avoid any that look damaged or that feel soft.

Find the Right Pot

Your pot should be a bit bigger than the bulb so the bulb’s roots can stretch out comfortably. Make sure it has holes at the bottom so water doesn’t get trapped, which can cause root rot and harm the bulb.

Planting Depth

Plant the bulb in the pot in well-draining soil, leaving about one-third of the bulb above the soil.

Watering

Give your newly planted bulb a good drink, but don’t drown it. Let the soil dry out a bit before watering again. Don’t keep the bulb in soggy soil.

The Right Spot

Put your pot where it gets plenty of light but not too much direct sun. A little warmth, between 60-75°F, is just right.

Watch and Wait

Wait for the flower to grow, patience will be rewarded. As your Amaryllis grows, you might need to give it a little support with stakes so it doesn’t tip over.

When to Plant Amaryllis Bulbs

The best time to plant amaryllis bulbs indoors depends on when you want them to bloom.

  1. Fall/Winter Blooming (December to January):
    • Plant bulbs in September or October if you want your amaryllis to bloom in December or January. This timing allows for the eight to ten weeks needed for the bulb to flower after planting.
  2. Winter/Spring Blooming (January to April):
    • Plant bulbs in November or December for a winter to spring bloom. Again, this allows for the eight to ten weeks required for the flowering process.

After it's finished blooming....then what? Mine bloomed beautifully this past Christmas. I want to keep them inside, not planted outdoors.

What should you do with the amaryllis to help it re-bloom? Does the bulb need to be dug up and later repotted? I cut off the dead leaves and put it in the dark, but it grew white leaves. So I cut them back and put it in the sun.

Hi Cheryl, To encourage amaryllis re-blooming, you can leave the bulb in the pot, no need to dig it up. You did the right thing trimming the dead leaves. The white leaves do often indicate insufficient light, so the sun exposure should help. I'll keep my fingers crossed for your Amaryllis to rebloom!

What do I do when it's through blooming ?

Hi Char, When your Amaryllis is done blooming, you can trim the faded flowers, but leave the green leaves. Continue to water as normal. When the leaves start yellowing, gradually reduce watering. Let the plant go into dormancy in a cool, dark place. After the dormancy period, bring it back into light, resume watering, and enjoy the next bloom cycle.
