Fertilize plants monthly from the time new growth starts in late winter or early spring, and throughout the summer using a one-half strength soluble fertilizer, such as a 20-10-20 or 20-20-20 with trace elements. Holiday cacti have a higher requirement for magnesium than many other plants, so you may want to use a magnesium-richfertilizer in the spring and summer. If the soil is too alkaline, the plants will not be able to take up the magnesium and they will die.
Too acidic soil will kill the cactus, but it is not necessary to fertilize in this case. pH should be between 5.6 and 6 in order for the plant to absorb the necessary amount of magnesium. You can also add a few drops of liquid magnesium sulfate or magnesium chloride to the water to help with the absorption of the mineral.

Can I use Miracle Grow on Christmas cactus?
Christmas cactus can be planted in the Miracle-Gro® Cactus, Palm and Citrus Potting Mix. When the top 1 to 2 inches of soil is dry, you have to water it. The humidity around the plant should be increased. Feed from fall to spring with Miracle-Gro Succulent Food.
Should a Christmas cactus be fed while blooming?
Christmas cacti should not be fed when they are budding out. Christmas cacti start forming flower buds in the middle of the summer, so you should wait until the buds are fully formed before fertilize.
Fertilizing too early can cause the cactus to over-produce flowers, which can be a problem if you are trying to get the most out of your plants. If you have a lot of plants, you may want to wait a few weeks after fertilization to see if the plants are ready to flower.
How often should a Christmas cactus be fed?
Feed every 2 weeks during the spring and fall. Feed the cactus monthly in the fall and winter to encourage it to bloom. Prune plants in the late spring to encourage branching.
Cacti can be grown in containers, but they are best grown outdoors in full sun or in partial shade. They do best in a well-drained soil with good drainage. Water regularly to keep the soil moist but not soggy. Do not overwater, as this can lead to root rot.
What is the best feed for Christmas cactus?
Once buds appear, fertilize them every two weeks. Ensuring you get a beautiful, full bloom by feeding them monthly from spring through summer is possible.
How do I keep my Christmas cactus blooming?
Christmas cacti produce flowers in a short day cycle. When the plants are ready to flower, they will begin to open their petals and produce a small amount of pollen. When the pollen reaches the ground, it begins to germinate, which is the process by which new seeds are produced. This process takes place in the soil, but it can also take place at the top of a plant.
Once the seedlings have reached a height of about one foot, a thin layer of soil will form around them. At this point, all that is left to do is to wait for the weather to warm up and the temperature to drop below freezing. During the winter months, this process can take up to three months.
What does coffee do for Christmas cactus?
Coffee grounds are an excellent addition that will provide nitrogen and keep the soil from becoming too acidic since Christmas cactus likes an acidic soil. Coffee grounds can also be used as a fertilizer, but it’s best to use them in a well-drained soil that has a pH of around 7.0 or higher.
Coffee grounds should be added to the top of the compost pile, not in the bottom, and should not be allowed to dry out before adding them to your soil. If you do this, you’ll end up with a compost that’s too alkaline and won’t be able to support the growth of your cacti and succulents.
When should you put a Christmas cactus in the dark?
You should put your forest cactus in a dark closet for 14 hours a night, starting six to eight weeks before you want it to bloom. It’s a good idea to bring it back out during daylight hours. Once buds begin to form, the closet treatment is no longer necessary, and the plant should bloom within a week or two.
If you don’t have a closet, you can grow your cacti in the ground, but you’ll need to keep the soil moist and well-drained to prevent root rot. You can also use a soil-less medium, such as peat moss or vermiculite, as long as it’s not too wet or too dry.
Should I be misting my Christmas cactus?
You should be misting, not watering, every day. A few squirts from a spray bottle is all it takes to keep your cactus happy. The only time you should be watering the base of the plant is when its soil is completely dry.
Does Christmas cactus like sun or shade?
When cacti are placed in a location with partial shade, such as an east or west facing window, they grow best. Cactus and succulents can tolerate temperatures as low as 50 degrees F, but they will not grow well in temperatures below 40 degrees. They will also not thrive in areas that are too hot or too cold for them to survive.
