Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); adjust for intense summer sun by providing partial shade.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from scorching midday sun; move indoor plants to a south-facing window for optimal light.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant weekly for even growth; use sheer curtains to filter harsh sunlight; avoid placing near reflective surfaces that intensify light.
Watering
every 7–10 days during active growth, reduce to every 3–4 weeks in dormancy
Water thoroughly but infrequently; avoid waterlogged soil; adjust frequency based on season and growth stage.
Soil
well-draining, slightly sandy potting mix
pH: Slightly acidic to neutral (6.0–7.0).
Use terra cotta pots for better drainage; avoid heavy garden soil; topdress with compost annually.
Temperature
Warm temperatures (65–85°F / 18–29°C) during active growth; tolerate brief dips to 50°F (10°C) but thrive in warmth.
Avoid sudden temperature changes; protect from frost; maintain warmth during dormancy for better recovery.
Fertilizing
every 2 weeks during active growth with balanced liquid fertilizer, none in dormancy
Dilute fertilizer to half strength; fertilize after watering to prevent root burn; focus on bloom-boosting formulas during flowering.
Propagation
Methods
Stem cuttings (softwood or semi-hardwood).
Step-by-Step Propagation Guide
- Take a 6–8 inch cutting.
- Let it callus for 1–2 days.
- Apply rooting hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when temperatures are warm and humidity is moderate.
Environment
Warm (75–85°F / 24–29°C), high humidity (70–80%), and bright indirect light.
Medium
Well-draining mix of perlite, sand, and peat moss; or cactus/succulent potting mix.
Hormone
Recommended (rooting hormone with auxins).
Timeline
Roots develop in 4–8 weeks; new growth appears in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, pot, well-draining medium, misting bottle.
Quick Tips
Allow cuttings to callus to prevent rot; maintain humidity with a plastic cover; avoid direct sun until roots form.
Pruning & Repotting
Pruning Guide
Method
Selective branch removal; cut just above a node or bud; avoid leaving stubs.
Pruning Plan
Shape the plant, encourage bushier growth, and remove dead/diseased wood.
Tools
Pruning shears, loppers (for larger branches), sterilizing solution.
Checklist
Sterilize tools; prune during dormancy; remove crossing branches; shape evenly.
Repotting Guide
Best Season
Early spring before active growth starts.
Pot Size
Increase pot size by 2–3 inches in diameter; avoid oversized pots.
Method
Remove plant gently; trim roots if necessary; use fresh well-draining soil; ensure pot has drainage holes.
Suggestions
Repot every 2–3 years or when roots fill the pot; essential for young, fast-growing plants.
Checklist
Check root bound status; prepare new pot and soil; prune roots if needed; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust for season.
How to Apply Water Properly
Water at the base, ensuring moisture reaches the root zone; water until it drains from the bottom; avoid wetting foliage; water in the morning for optimal absorption.
Watering Schedule Tips
Water deeply once a week during active growth (spring/summer); reduce to every 2–3 weeks in fall/winter; allow soil to dry completely between waterings.
Soil Improvement
Add perlite, coarse sand, or pumice to improve aeration and drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf drop in cold stress; wilting or scorching in excessive heat.
Cold Stress
Growth slows or halts; leaves may yellow or drop; risk of root rot if soil remains wet in cold.
Solution: Move to a warmer location; protect from drafts; reduce watering in cool conditions; use a heat mat if necessary.
Hot Stress
Wilting despite moist soil; leaf scorch or sunburn; reduced flowering.
Solution: Provide shade during peak heat; increase humidity with misting; ensure adequate water but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute correctly; apply during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced (10-10-10) or high-phosphorus fertilizer every 2–4 weeks during spring/summer; reduce or stop in fall/winter.
