Care Details
Ideal Sunlight Coverage:
Full sun to partial shade; 6–8 hours of direct sunlight daily, with some protection from intense midday sun in hot climates.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; provide shade during peak heat; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant for even light exposure; use sheer curtains to filter intense sun; avoid sudden light changes.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom; allow soil to dry between waterings; adjust based on season and growth stage.
Soil
well-draining, loamy soil with organic matter
pH: Slightly acidic to neutral, pH 6.0–7.0.
Use a mix that doesn’t compact easily; ensure pots have drainage holes; avoid heavy clay soils.
Temperature
Prefers warm temperatures, ideally 65–85°F (18–29°C); tolerates brief dips to 50°F (10°C) but thrives in consistently warm conditions.
Protect from frost; avoid placing near drafty windows; maintain consistent warmth for best growth.
Fertilizing
every 4–6 weeks during growing season
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; use a balanced formula for overall health.
Propagation
Methods
Stem cuttings or seeds; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Apply rooting hormone.
- Plant in moist medium.
- Keep humid 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 potting mix, such as a mix of peat, perlite, and sand.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots may develop in 4–8 weeks; new growth typically appears after 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity with a plastic cover; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Use clean cuts just above a leaf node or branch junction; remove crossing or inward-growing branches.
Pruning Plan
Prune to maintain shape, remove dead/diseased wood, and encourage bushier growth; focus on structural improvement.
Tools
Pruning shears, loppers (for larger branches), disinfectant.
Checklist
Disinfect tools; prune during dormancy or early growth; remove dead/diseased wood first; shape evenly.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure the new pot has drainage holes.
Method
Remove plant gently; trim any circling roots; place in a slightly larger pot with fresh, well-draining soil; water lightly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the pot; necessary to refresh soil and provide space for growth.
Checklist
Choose appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting; place in shade for a few days.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring even saturation of the root zone; avoid wetting foliage; ensure excess water drains away to prevent waterlogging.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure aeration with organic matter.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, yellowing, slowed growth, or wilting in response to extreme cold or heat.
Cold Stress
Low temperatures slow growth, cause leaf drop, and may lead to root damage if prolonged below 50°F (10°C).
Solution: Move to a warmer location; provide frost protection; reduce watering in cold periods to prevent root rot.
Hot Stress
Excessive heat can cause leaf scorch, wilting, and reduced vigor, especially if combined with drought stress.
Solution: Provide shade during peak heat; increase watering; ensure good air circulation; mist foliage in extreme heat.
Fertilizing Guide
Fertilizing Checklist
Check growth stage; dilute fertilizer correctly; apply to moist soil; avoid contact with roots.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during the growing season (spring and summer); avoid fertilizing in fall and winter.
