My grandmother had a Christmas cactus that bloomed like clockwork every December, and she never seemed to do anything to it. When she gave me a cutting, I expected the same magic. My first one bloomed exactly once, in June, out of spite.

Then I learned the secret: this plant blooms when you make it slightly miserable on schedule.

It Needs a Rest Period

Christmas cacti set buds when they get about 6 weeks of short days and cool nights. Starting in October, give it 12 to 14 hours of darkness daily and keep it somewhere around 55 to 65 degrees.

I moved mine to a spare room that stays cool and dark for most of the evening. It is the least glamorous plant care I do, and it works.

Do Not Overwater the Drama Queen

This is a cactus in name only. It is a tropical plant that likes moisture, but the roots rot fast in soggy soil. Water when the top inch of soil feels dry.

During the rest period, water even less. I let mine go almost dry between waterings and the buds showed up right on schedule.

Keep Light Bright but Indirect

Bright, indirect light is the sweet spot. Direct summer sun burns the leaves and turns them reddish. A north or east window works great for most of the year.

Turn the pot a quarter turn every week so it does not grow lopsided toward the light. My grandmother never did this, but hers was on a porch, so the sun did the work.

Feed Lightly

A balanced houseplant fertilizer once a month from spring through summer is plenty. Stop feeding when the buds appear so they do not drop.

The biggest cause of dropped buds is moving the plant while it is blooming. Pick a spot before the buds form and leave it alone. I learned this by moving mine to show a friend, and watching every bud fall off the next day.

When It Is Done Blooming

After the flowers fade, trim a few segments if the plant is getting leggy. Those cuttings root in water in a few weeks, which is how I now have three plants for the price of one.

Keep the routine going and your cactus will bloom every year, and you will have cuttings to share with everyone you know.
