How to care for Sweetheart Plant

Difficulty

Sweetheart Plant is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.

Water

Sweetheart Plant does best in dry soil and should only be watered sparingly.

Soil

Sweetheart Plant loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

To ensure optimal growth, the Sweetheart Plant prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the cold period, it is common for Sweetheart Plant to go dormant and their growth may slow down, so waterings should be spaced out more during this period.
