Outdoor Schlumbergera Cultivation

Christmas cactuses, also known as Thanksgiving cactuses, belong to the Schlumbergera genus and thrive in partial sun or shady gardens with moderate summer temperatures and mild winters. For successful outdoor cultivation, follow these tips:

Choose a location with light shade or morning sun, avoiding hot afternoon sun.
Plant them in humus-rich soil with good drainage, using loamy or sandy soil amended with materials like landscape sand or pumice.
Water regularly, ensuring the soil doesn’t become bone dry to prevent root rot.
Pay attention to flowering cues, as Christmas cactuses bloom in response to longer nights and cooler temperatures.

Pruning and Maintenance

Proper pruning and maintenance are essential for ensuring healthy growth and abundant flowering in Christmas cactuses. Follow these tips for optimal care:

Prune your plants right after flowering using clean, sharp tools to shape them and promote branching.
Use trimmings to propagate new plants easily.
Apply a layer of bark mulch for winter insulation and side dress with aged compost in spring.
Feed plants monthly with a balanced liquid fertilizer during the growing season and withhold feeding in autumn and winter.

Container Care

If you prefer to grow your Christmas cactus in containers, follow these guidelines for optimal care:

Choose pots with drainage holes and add a layer of drainage material at the bottom.
Use a rough-textured, humus-rich potting blend with good drainage.
Water when the top inch of soil is dry and fertilize every two weeks during the growing season.

Moving Inside Pots Out

Moving your houseplants outdoors for the growing season can help ensure a full bud set and abundant flowers. Follow these steps for a successful transition:

Gradually acclimate your plants to outdoor conditions by increasing their time spent outdoors over the course of a week to 10 days.
Water and fertilize as needed during the outdoor growing season.
Move plants back indoors when temperatures drop to 50°F, taking care to avoid drafts or warm air blowing from heat vents.

Managing Pests and Disease

While Christmas cactuses are generally problem-free, they can be affected by pests and diseases. Follow these tips to protect your plants:

Watch for pests like mealybugs and aphids, and use insecticidal soap or neem oil for control.
Prevent diseases by ensuring good drainage and watering only when the top inch of soil is dry.
