A Comprehensive Guide to Feeding Your Christmas Cactus

If you were lucky enough to receive a Christmas cactus as a gift during the winter holidays, then you know how beautiful and vibrant these plants can be.

By fertilizing it at the right time, you can ensure that your plant will be filled with brightly colored tubular blooms.

Understanding Christmas Cactus Feeding Requirements

Christmas cacti, which belong to the Schlumbergeria species, are native to Brazil and are known for their trailing jointed stems and stunning flowers. These plants make perfect houseplants and are relatively easy to care for. They thrive in indirect, bright light and require well-draining soil and average moisture.

Feeding your Christmas cactus is crucial during the growing season, which typically runs from April to October. By providing the right nutrients during this period, you can help your cactus produce healthy growth and form buds that will eventually blossom just in time for Christmas.

If you don’t plan on keeping your cactus as a gift, you can skip the fertilizing process. However, keep in mind that without proper nourishment, the soil will eventually deplete its nutrients, causing the plant to slowly starve to death. If you want to revive a lethargic cactus, consider repotting it in fresh soil and adding a well-balanced houseplant fertilizer at the right time.

The Art of Feeding a Christmas Cactus

To effectively feed your Christmas cactus, you can choose between a bloom formula houseplant fertilizer or a half-strength water-soluble formula, such as 20-20-20 or 20-10-20. These options are ideal for providing the necessary nutrients to your cactus. Feed your plant with these fertilizers monthly during regular watering from late winter to late summer.

Alternatively, you can opt for a time-release balanced plant food or a slightly higher phosphorus formula once a month in mid to late summer. These options can help enhance flowering and ensure your Christmas cactus blooms in all its glory.

Additionally, on alternate weeks, consider using Epsom salts. Mix one teaspoon per gallon (5 ml per approx. 4 L) of water and use it as a fertilizer. This routine will fulfill all the nutrient requirements of your Christmas cactus, including its high magnesium needs.

Remember to stop fertilizing in late summer to allow the plant to prepare for blooming. During winter, when the plant is not actively growing, it does not require any fertilization.

General Care Tips for Your Christmas Cactus

While feeding your Christmas cactus is important, it is only part of the overall care routine. Here are a few additional tips to keep your cactus happy and healthy:

  • Rarely repot your Christmas cactus as they prefer a crowded environment. However, every few years, you should replace the soil. A mixture of half potting soil and half sand or perlite will suffice.
  • Avoid letting the bottom of the pot stand in water to prevent root rot.
  • After blooming, pinch off the ends of stems to encourage branching. You can even root these cuttings by allowing the edges to callus in a mixture of sand and soil or pure vermiculite.
  • If desired, you can move your cactus outdoors during the summer. However, be sure to protect it from harsh sunlight, which can burn the stems.
  • Keep an eye out for pests like mealybugs or scale insects. If necessary, combat them with a good horticultural soap spray.

With these care tips and proper feeding, your Christmas cactus will reward you with a stunning display of flowers at the end of the year. Enjoy the beauty and joy that this resilient houseplant brings to your home!
