Care Details
Ideal Sunlight Coverage:
Full sun to partial shade; 6–8 hours of direct sunlight per day is ideal, though it can tolerate some afternoon shade in hot climates.
Sunlight Tolerance Tips:
Acclimate the plant gradually to intense sunlight if moving from shade; protect from harsh afternoon sun in arid regions; ensure good air circulation to prevent sunburn.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate the plant weekly for even light exposure; use shade cloth in extreme heat; avoid placing in drafty areas.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom, avoid frequent shallow watering, and adjust frequency based on season and weather.
Soil
well-drained, loamy soil with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix with good drainage; avoid heavy clay soils; top-dress with compost annually.
Temperature
Prefers warm temperatures between 65–85°F (18–29°C); can tolerate mild frosts but thrives in subtropical to tropical conditions.
Protect from frost; provide shade in extreme heat; maintain consistent temperatures for optimal growth.
Fertilizing
every 2 months during spring and summer
Fertilize in spring before new growth; avoid over-fertilizing to prevent salt buildup; flush soil occasionally to remove excess salts.
Propagation
Methods
Stem cuttings or seed; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in propagation medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain temperatures around 70–75°F (21–24°C).
Medium
Well-draining mix of perlite and peat moss or cactus potting mix.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots may develop in 4–8 weeks; establishment may take several months.
Tools Needed
Pruning shears, rooting hormone, propagation tray, misting bottle, plastic wrap.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Selective pruning of individual branches; avoid heavy shearing to maintain natural form.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased wood; best done after flowering or in late winter/early spring.
Tools
Pruning shears, loppers, gloves, disinfectant.
Checklist
Disinfect tools; prune after flowering; remove dead/diseased wood; shape as desired.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 2–3 inches in diameter; avoid oversized pots.
Method
Remove plant gently; trim any circling roots; place in a slightly larger pot with fresh, well-draining soil; water thoroughly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for young plants to encourage growth.
Checklist
Choose appropriate pot size; use fresh soil mix; trim roots if necessary; water well after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust frequency seasonally.
How to Apply Water Properly
Water directly at the root zone, ensuring even saturation of the soil; water early in the morning or late in the evening to minimize evaporation; allow excess water to drain completely to prevent root rot.
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, allowing soil to dry completely between waterings.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, wilting, or browning leaf edges in cold stress; scorching or yellowing leaves in excessive heat.
Cold Stress
Low temperatures slow growth and can cause leaf drop or damage if below 25°F (-4°C); prolonged cold may lead to root damage.
Solution: Move potted plants indoors or to a sheltered location; use frost cloth for outdoor plants; ensure good drainage to prevent cold soil saturation.
Hot Stress
Excessive heat can cause leaf scorch, wilting, or reduced flowering; may lead to dehydration if water needs are not met.
Solution: Provide partial shade during peak heat; increase watering frequency; use mulch to retain soil moisture; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; apply in spring; dilute liquid fertilizer; avoid winter feeding.
Fertilizing Method
Use a balanced, slow-release fertilizer in spring; dilute liquid fertilizer to half-strength every 4–6 weeks during growing season; avoid fertilizing in winter.
