Holiday Cactus Basics

Christmas and Thanksgiving cacti, also known as Schlumbergera, are epiphytes native to tropical rainforests of Brazil. With their stunning flowers and easy-care requirements, they make ideal houseplants. These plants thrive in bright, indirect light, well-draining soil with a slightly acidic pH, and average moisture levels.

Bud set in holiday cacti occurs during the cooler days of fall when the dark of night lengthens noticeably. These short day/long night plants require specific environmental conditions to induce flowering, typically triggered when daylight hours dwindle to 12 hours or less. By understanding their photoperiodic response, you can encourage abundant blooms during the holiday season.

When and How to Feed

To promote healthy growth and abundant bud set in your Christmas cactus, it’s crucial to fertilize them during the growing season from spring to summer. Start fertilizing in early spring as new growth emerges, using a half-strength balanced liquid formula such as 10-10-10 (NPK) on a monthly basis.

Additionally, supplement your plants with magnesium sulfate (Epsom salts) in a diluted solution to provide essential nutrients. Alternate between feeding with Epsom salts and a balanced fertilizer every two weeks for optimal results. Don’t forget to give your plants a final feeding at the end of summer to boost bud set.

If you prefer a convenient fertilizing schedule, consider using slow-release pellets with a balanced formula or nutrient-rich compost. Apply the fertilizer in early spring and again in midsummer to support healthy growth and flowering.

Leach the Soil

Regular fertilization can lead to a buildup of mineral salts in the soil, potentially harming your plants’ roots. Leaching the soil after the flowering period can help prevent this issue. Simply place your pot in a sink or bucket and water it with distilled or filtered water to dissolve the salts. Allow the water to drain out, cleansing the soil and revitalizing your plants.

Growing Tips

In addition to a consistent feeding schedule, here are some growing tips to help your Christmas cactus thrive:

Allow the top inch of soil to dry out between waterings in spring and summer.
Increase watering slightly in fall to maintain lightly moist soil during bud set.
Keep your plants slightly root-bound in well-draining soil.
Empty water catchment saucers to prevent waterlogging.
Mist your plants weekly in winter to increase humidity.
Avoid direct heat sources and strong sunlight exposure.

By following these growing tips and maintaining a regular feeding schedule, you can enjoy vibrant, blooming holiday cacti throughout the winter season.

Blooming Beautiful!

For blooming beautiful holiday cacti, remember to fertilize your plants regularly with a balanced liquid or slow-release formula. Opt for natural fertilizers like compost or worm castings for a sustainable alternative. And don’t forget to leach the soil after flowering to ensure the overall health of your plants.
