Care Requirements
Care Difficulty
very easymoderate
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains in intense sun; move outdoors in spring/summer.
Watering
every 7–10 days, allowing soil to dry between waterings
Water thoroughly but infrequently; ensure proper drainage; adjust based on season and growth stage.
Soil
well-drained, sandy loam with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use raised beds for drainage; avoid heavy clay soils; amend with compost annually.
Temperature
Prefers cool to moderate temperatures (60–75°F or 15–24°C); tolerates mild frost but avoid extreme heat.
Protect from frost; avoid sudden temperature swings; adjust watering in heat.
Fertilizing
every 4–6 weeks during active growth with balanced liquid fertilizer
Dilute fertilizer to prevent burn; fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in hormone (optional).
- Plant in medium.
- Keep moist and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F or 21–24°C), high humidity, and indirect light.
Medium
Well-draining mix like perlite and peat moss or cactus mix.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruners, rooting hormone, propagation tray, misting spray bottle.
Quick Tips
Use healthy parent plants; maintain humidity with a cover; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushiness; cut just above a leaf node or bud.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead/damaged growth.
Tools
Clean, sharp pruners or scissors.
Checklist
Sanitize tools; prune dead/damaged growth; 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 new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and soil freshness.
Checklist
Choose new pot; prepare fresh soil; handle roots carefully; water after repotting.
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 moisture reaches the root zone; avoid wetting foliage; allow excess water to drain away.
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 sand for drainage; incorporate compost for fertility; ensure aeration with organic matter.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or stunted growth in extreme heat; yellowing or browning leaves in cold stress.
Cold Stress
Slows growth; may cause leaf discoloration or dieback in prolonged cold.
Solution: Provide frost protection; move indoors in freezing temperatures; avoid overwatering in cold.
Hot Stress
Leaves may scorch, wilt, or drop; growth may stall in excessive heat.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth stage; dilute fertilizer; apply to moist soil; avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
