Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily). Tolerates partial shade but may become less vigorous.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight to prevent scorching. In hot climates, provide some afternoon shade to avoid leaf burn. Indoors, place near a south-facing window.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun
Rotate plant for even growth; use sheer curtains to filter intense light; avoid sudden light changes.
Watering
every 7–14 days, depending on climate and soil conditions
Water thoroughly until runoff, allow soil to dry between waterings, and avoid overhead watering to prevent fungal issues.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Avoid heavy clay soils; ensure good drainage; amend with compost annually.
Temperature
Thrives in warm temperatures (65–85°F / 18–29°C). Tolerates heat well but may go dormant in extreme cold.
Monitor temperature extremes; adjust watering with temperature changes; protect from frost.
Fertilizing
every 3–4 months during active growth
Fertilize lightly; avoid over-fertilization; apply before new growth emerges.
Propagation
Methods
Stem cuttings or division of clumps.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- 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 / 21–24°C), high humidity, and bright indirect light.
Medium
Well-draining potting mix with perlite or sand.
Hormone
Optional, but rooting hormone can improve success rates.
Timeline
Roots develop in 4–6 weeks; establish in new pots within 2–3 months.
Tools Needed
Pruning shears, rooting hormone, pots, well-draining mix.
Quick Tips
Use healthy parent plants; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinching back tips or cutting stems just above a leaf node.
Pruning Plan
Remove dead or damaged foliage to maintain vigor and appearance. Prune to shape and encourage bushier growth.
Tools
Pruning shears, sharp knife, gloves.
Checklist
Use clean tools; prune dead/damaged growth; shape as desired; dispose of clippings.
Repotting Guide
Best Season
Spring, before the active growth period begins.
Pot Size
Increase pot size by 2–3 inches in diameter.
Method
Remove plant gently; trim roots if necessary; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the container. Necessary to refresh soil and provide space for growth.
Checklist
Choose appropriate pot; prepare new soil; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture with a finger; water deeply; ensure drainage; avoid wetting foliage.
How to Apply Water Properly
Water directly at the root zone, ensuring even saturation to a depth of 6–8 inches. Ensure excess water drains freely to prevent waterlogging, and water early in the morning to minimize evaporation.
Watering Schedule Tips
Water deeply once every 7–10 days during active growth, reducing frequency to every 2–3 weeks in winter. Adjust based on rainfall and soil moisture retention.
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
Chlorosis or browning of leaf tips in excessive heat; stunted growth or leaf drop in cold stress.
Cold Stress
Low temperatures slow growth and may cause leaf discoloration or dieback. Prolonged cold can lead to root damage.
Solution: Provide frost protection in cold climates; mulch heavily to insulate roots; move potted plants indoors during freezes.
Hot Stress
Excessive heat can cause wilting, leaf scorch, or premature dormancy, especially if combined with drought.
Solution: Increase watering frequency; provide partial shade during peak heat; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; follow dilution instructions; fertilize during active growth only.
Fertilizing Method
Use a balanced, slow-release fertilizer in spring and early summer. Dilute liquid fertilizer to half-strength if applied monthly during growth periods. Avoid fertilizing in winter.
