Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily). Tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate new plants gradually to full sun to prevent scorching. Indoors, place near a south-facing window. Outdoors, ensure unobstructed sunlight.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun
Rotate plant for even growth; provide shade during extreme heat; avoid sudden light changes.
Watering
every 2–3 weeks, allowing soil to dry completely between waterings
Water deeply but infrequently; ensure excellent drainage; avoid overhead watering to prevent leaf rot.
Soil
well-draining, sandy or rocky soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil dries quickly; avoid heavy clay mixes; use terracotta pots for better drainage.
Temperature
Prefers 60–75°F (15–24°C). Tolerates cold down to 0°F (-18°C) but thrives in moderate warmth.
Avoid sudden temperature shifts; protect from frost; monitor for signs of stress.
Fertilizing
rarely needed, apply a balanced liquid fertilizer once in early spring
Dilute fertilizer to half strength; apply to moist soil; skip fertilizing if plant is stressed.
Propagation
Methods
Stem cuttings or division. Stem cuttings root easily in soil or water.
Step-by-Step Propagation Guide
- Take a 3–4 inch cutting.
- Let it callus for a day.
- Plant in moist soil or water.
- Keep warm and bright.
Best Time: Spring or early summer when plant is actively growing.
Environment
Warm (65–75°F), bright indirect light, high humidity (optional for cuttings).
Medium
Well-draining soil mix (e.g., cactus mix) or water.
Hormone
Not necessary, but can speed up rooting.
Timeline
Roots form in 1–2 weeks; new growth appears in 4–6 weeks.
Tools Needed
Sharp scissors, rooting hormone (optional), small pots, well-draining soil.
Quick Tips
Use healthy, non-flowering stems; keep soil lightly moist; avoid direct sun until rooted.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead/damaged stems.
Tools
Clean, sharp scissors or pruning shears.
Checklist
Sterilize tools; prune dead/damaged stems; shape as desired; dispose of clippings.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter).
Method
Remove plant gently; trim roots if needed; place in fresh, well-draining soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot. May become root-bound, which can limit growth.
Checklist
Choose appropriate pot; prepare fresh soil; handle roots carefully; water sparingly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil dryness; water deeply; ensure drainage; avoid wet foliage.
How to Apply Water Properly
Water directly at the soil level, ensuring moisture reaches the root zone without saturating. Water early in the day to allow foliage to dry. Ensure excess water drains away completely.
Watering Schedule Tips
Water sparingly, allowing soil to dry completely between waterings. Reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite, coarse sand, or pumice to improve drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting in heat; stunted growth or leaf drop in cold; yellowing in extreme conditions.
Cold Stress
Slows growth; may enter dormancy; roots can freeze in poorly drained soil.
Solution: Ensure well-draining soil; protect roots from frost; move potted plants indoors in severe cold.
Hot Stress
Leaf scorch; dehydration; reduced flowering; may go dormant in extreme heat.
Solution: Provide partial shade during peak heat; increase watering cautiously; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced, diluted liquid fertilizer monthly during growing season (spring/summer). Avoid fertilizing in fall/winter.
