Caring for Dwarf Jade and Companion Plants Under Grow Lights

Dwarf Jade (Portulacaria afra) and Mixed Planting Care

Dwarf jade is a succulent native to arid South Africa. It stores water in leaves and stems, requiring infrequent watering and abundant light. The companion plant described—thick, grass-like blades from a central root—is likely a Crassula species, also a succulent.

Correcting Care Mistakes

• Watering: “Every other day” is far too frequent. Water only when the soil is completely dry—typically every 2–3 weeks indoors. Soak thoroughly, then drain completely.
• Light: A grow light 18 inches away for 14 hours is a good start, but succulents need high intensity. Use a full-spectrum LED (3000–5000K) at 12–18 inches, 12–14 hours daily. Rotate plants for even growth.
• Soil: Use a gritty, fast-draining mix (50% pumice/perlite, 25% coarse sand, 25% organic matter). Repot if the current soil retains moisture.

Summer Transition

Move both plants outdoors after frost danger passes. Acclimate gradually: 1 week in full shade, then increasing sun exposure over 2 weeks. Morning sun with afternoon shade is ideal. Outdoor light and airflow dramatically improve health and compact growth.

Yellowing Leaves on Companion

This suggests overwatering or insufficient light. Allow soil to dry completely between waterings. If the plant continues to decline, it may be a different species with distinct needs—consider separating them into individual pots with tailored care.
