Care Requirements
Care Difficulty
very easymoderate
Sunlight
full sun to partial shade
Rotate plants for even light exposure; use shade cloth in extreme heat; avoid direct sun on leaves during peak hours.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overhead watering.
Soil
well-draining, sandy loam with moderate organic content
pH: Slightly acidic to neutral (6.0–7.0).
Use raised beds for better drainage; avoid heavy clay soils; amend with organic matter annually.
Temperature
Prefers cool to moderate temperatures (60–75°F); can tolerate mild frosts.
Avoid sudden temperature changes; protect from drafts; maintain consistent temperatures for optimal growth.
Fertilizing
every 4–6 weeks during growing season, none in winter
Apply fertilizer after watering; flush soil occasionally to prevent salt buildup; use organic options for gentle feeding.
Propagation
Methods
Stem cuttings or seed; stem cuttings are faster and more reliable.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Keep moist.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F), humid, and bright indirect light; protect from direct sun.
Medium
Well-draining potting mix with perlite or sand; can also root in water.
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, small pots, well-draining mix.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity with a plastic bag; avoid overwatering.
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 or diseased growth.
Tools
Clean, sharp pruners or scissors.
Checklist
Sterilize tools; prune dead/damaged growth; shape the plant; clean up debris.
Repotting Guide
Best Season
Spring, before the active growth period.
Pot Size
Choose a pot 1–2 inches larger in diameter than the current one.
Method
Remove plant gently; trim roots if crowded; place in a new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and health.
Checklist
Check root bound status; prepare new pot; trim roots; add fresh soil; water lightly.
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 early in the day to minimize evaporation.
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 sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or flower bud drop.
Cold Stress
Slows growth and may cause leaf discoloration; severe cold can damage or kill the plant.
Solution: Provide frost protection in winter; move potted plants indoors; use row covers for garden plants.
Hot Stress
Leaves may wilt, scorch, or drop; flowering may be reduced.
Solution: Provide afternoon shade; increase watering; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to soil; avoid foliage contact.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during active growth; avoid fertilizing in winter.
