Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to filter intense light; avoid placing in shaded corners.
Watering
every 7–10 days, allowing soil to dry between waterings
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overhead watering.
Soil
well-draining, sandy or loamy soil with low fertility
pH: 6.0–7.5 (slightly acidic to neutral)
Ensure soil dries between waterings; avoid heavy clay soils; amend with organic matter for nutrients.
Temperature
Prefers 60–75°F (15–24°C); tolerates cooler temperatures but not frost.
Protect from frost; avoid placing near drafty windows; maintain consistent temperatures.
Fertilizing
every 4–6 weeks during active growth, with a balanced liquid fertilizer
Use a balanced fertilizer; dilute to prevent burning; fertilize during active growth only.
Propagation
Methods
Stem cuttings
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Maintain humidity.
Best Time: Late spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), indirect light, and warm temperatures (65–75°F).
Medium
Well-draining potting mix with perlite or sand
Hormone
Recommended to use rooting hormone for faster root development.
Timeline
Roots develop in 3–4 weeks; plants can be transplanted after 8–10 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinching back tips for bushier growth; cutting back stems to just above a leaf node.
Pruning Plan
Prune to maintain shape, encourage bushiness, and promote airflow; remove dead or diseased growth.
Tools
Pruning shears, sharp scissors, gloves.
Checklist
Sterilize tools; prune in early spring; remove dead/diseased parts; shape the plant.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
Increase pot size by 1–2 inches in diameter.
Method
Remove plant gently; trim roots if necessary; place in a new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; improves growth and prevents congestion.
Checklist
Check root bound status; prepare new pot; use fresh soil; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wetting leaves.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in extreme heat or cold.
Cold Stress
Growth slows or halts; leaves may turn purple or brown; risk of frost damage.
Solution: Move to a warmer location; provide frost protection in winter; avoid sudden temperature drops.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow; essential oils may diminish.
Solution: Provide partial shade during peak heat; increase watering; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute correctly; apply during growing season; avoid winter feeding.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during the growing season; avoid fertilizing in winter.
