Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates intense summer sun but benefits from some afternoon shade in extreme heat.
Sunlight Tolerance Tips:
Acclimate new plants gradually to full sun; protect from harsh afternoon sun in hot climates; ensure adequate light indoors if grown as a container plant.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun
Full sun is essential; rotate container plants for even growth; avoid deep shade.
Watering
every 7–14 days during active growth, less frequently in winter
Water thoroughly but infrequently to encourage deep root growth; allow soil to dry completely between waterings; avoid overwatering, especially in winter.
Soil
well-drained, sandy or loamy soil
pH: Slightly alkaline to neutral (pH 7.0–8.0).
Ensure excellent drainage; avoid heavy clay soils; amend with organic matter if needed.
Temperature
Thrives in hot, arid conditions; ideal range 70–100°F (21–38°C); tolerates temperatures down to 0°F (-18°C) but prefers warmth.
Protect from frost in winter; ensure full sun exposure; adjust watering in extreme heat.
Fertilizing
every 2–3 months during spring and summer
Fertilize sparingly; apply in spring only; avoid fertilizing stressed plants.
Propagation
Methods
Stem cuttings or seed; stem cuttings are more reliable for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Late spring or early summer when the plant is actively growing.
Environment
Warm (70–80°F), humid, and bright but indirect light; protect from direct sun.
Medium
Well-draining mix of perlite and peat moss or cactus mix.
Hormone
Recommended to use rooting hormone for faster root development.
Timeline
Roots develop in 4–6 weeks; establish in new pot after 3–4 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a plastic cover; keep soil consistently moist.
Pruning & Repotting
Pruning Guide
Method
Selective thinning and heading back to shape the plant and improve air circulation.
Pruning Plan
Prune to maintain shape, encourage flowering, and remove dead or weak growth; best done after flowering.
Tools
Pruning shears, loppers (for larger branches), gloves.
Checklist
Disinfect tools; prune after flowering; remove dead or crossing branches; shape evenly.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
Move to a pot one size larger (2–3 inches wider in diameter).
Method
Remove plant gently; trim roots if crowded; use fresh, well-draining soil; ensure proper drainage.
Suggestions
Repot every 2–3 years or when roots fill the container; beneficial for container-grown plants to refresh soil.
Checklist
Choose appropriate pot; prepare fresh soil mix; trim roots if needed; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust frequency by season.
How to Apply Water Properly
Water directly at the root zone until water drains from the bottom; ensure even moisture penetration; water early in the morning to minimize evaporation and fungal issues.
Watering Schedule Tips
Water deeply once every 7–10 days during active growth in spring and summer; reduce frequency to every 3–4 weeks in fall and winter. Adjust based on rainfall and soil dryness.
Soil Improvement
Add sand or perlite to improve drainage; incorporate compost for fertility; ensure soil is not compacted.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf drop in excessive cold; wilting or scorching in extreme heat.
Cold Stress
Slows growth and may cause leaf drop; prolonged cold can damage roots and stems.
Solution: Provide winter protection in colder zones (e.g., mulch, burlap wrap); avoid overwatering in cold weather.
Hot Stress
Leaves may wilt or scorch; growth may slow under intense heat.
Solution: Provide afternoon shade in extreme heat; water deeply but infrequently; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; apply in spring; follow package instructions; avoid over-fertilizing.
Fertilizing Method
Use a balanced, slow-release fertilizer in early spring; avoid high-nitrogen formulas; reduce or stop fertilizing in fall and winter.
