❓ Frequently Asked Questions — Comparing These Plants

Lithops

What are the light requirements for Lithops?

Lithops thrive in bright, indirect sunlight. They need at least 4-6 hours of direct sunlight per day, but intense afternoon sun can scorch their leaves, especially during the summer months. An east-facing window is ideal, providing gentle morning sun. If growing Lithops indoors, supplement natural light with a grow light, especially during the winter months when sunlight is limited.

How do I care for Lithops?

Lithops require very specific care to thrive. Provide them with extremely well-draining soil, such as a mix of pumice, perlite, and coarse sand. Water sparingly, only when the leaves become slightly wrinkled, typically during their active growing season (spring and fall). Avoid watering during dormancy (summer and winter) when the old leaves are being absorbed.

How do I propagate Lithops?

Lithops are typically propagated from seeds, as leaf cuttings and offsets are not viable methods. Stem cuttings are not applicable since Lithops lack a traditional stem. To propagate from seeds, sow them in a well-draining seed starting mix in spring or early summer. Keep the soil consistently moist but not waterlogged. Cover the container with a humidity dome or plastic wrap to maintain moisture.

Puka

What are the light requirements for Puka?

Puka trees prefer bright, indirect light. Direct sunlight can scorch their leaves, so avoid placing them in direct contact with intense sun. An east-facing window is ideal, providing gentle morning light. A north-facing window can also work, but the plant may grow more slowly. If you only have south- or west-facing windows, place the Puka tree a few feet away from the window or use sheer curtains to filter the light. Insufficient light can lead to leggy growth and a lack of vibrancy in the leaves. Rotate the plant regularly to ensure even light exposure on all sides.

How do I care for Puka?

Puka trees thrive in bright, indirect light, but can tolerate lower light conditions. Water when the top inch of soil is dry, allowing the soil to dry out slightly between waterings. Avoid overwatering, which can lead to root rot. Use a well-draining potting mix. Maintain moderate humidity levels. Fertilize every 2-3 months during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune to maintain shape and remove any dead or yellowing leaves. Repot every 1-2 years, or when the plant becomes root-bound, using a pot that is one size larger. Provide stable temperatures between 65-80°F (18-27°C). Protect from drafts and sudden temperature changes. Watch out for pests such as spider mites and mealybugs, and treat promptly if detected.

How do I propagate Puka?

Puka trees can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix. Keep the soil moist and provide bright, indirect light. Rooting should occur in 4-6 weeks. For air layering, make a small cut on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Roots should form within a few weeks. Once roots are visible, cut the stem below the rooted section and plant it in a pot.
