Best Christmas Cactus Fertilizer

Let’s get started!

What type of Fertilizer to use for Christmas Cactus?

Use a balanced fertilizer such as 10-10-10 or 20-20-20. You can also use a fertilizer that is high in phosphorus such as 5-10-5.

This will help to encourage blooming. This type of fertilizer is also good for cactus and succulents in general.

Should you fertilize the Christmas cactus?

Yes, you should fertilize your Christmas cactus to help it bloom. Fertilize with a balanced or high phosphorus fertilizer every two weeks from late fall to early spring.

This should be done whether your cactus is in a pot or on the ground. If you have a Christmas cactus that is not blooming, you may need to fertilize it more often.

Try fertilizing once a week for a few weeks and see if that helps.

When should I fertilize my Christmas cactus?

Christmas cactus should be fertilized when it is in bloom. You can use a liquid or solid fertilizer, but make sure it is for cactus and succulents. Follow the instructions on the package.

Fertilize every two weeks. You can also fertilize it in the spring before it blooms.

How to Feed a Christmas Cactus?

You can feed a Christmas cactus with a balanced liquid fertilizer or a 10-10-10 water-soluble powder. You should also use a fertilizer that is low in nitrogen and high in phosphorus and potassium.

Feed your cactus every two weeks when it is blooming and then reduce the frequency to once a month in the fall and winter. Do not overfertilize, as this can burn the cactus.
