ðą How to Care for Christmas Tree Plant to Prevent Stem Necrosis?
ð§ How to Water
Water thoroughly using the soak-and-dry method: water deeply until it drains from the bottom, then let the soil dry out completely before watering again (every 10â14 days). Never let roots sit in standing water â this is the leading cause of root rot.
âïļ Lighting
Provide full sun to bright indirect light. Outdoors, full sun is ideal. Indoors, place in a south- or west-facing window with at least 6 hours of bright light daily. Insufficient light causes leggy growth and poor flowering.
ðŠī Ideal Soil
Use a well-draining succulent or cactus mix. A blend of 60% peat moss (or coco coir) and 40% perlite works well. Good drainage is essential â avoid heavy clay soils that retain moisture.
