Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy with insufficient light.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight to prevent scorching; for indoor placement, use a south-facing window; outdoors, ensure protection from harsh midday sun in very hot climates.
Care Requirements
Care Difficulty
very easymoderate
Sunlight
full sun
Rotate plant weekly for even growth; use sheer curtains to filter intense light indoors; avoid sudden light changes.
Watering
every 7–10 days during active growth, less frequently in dormant periods
Water thoroughly until runoff occurs; ensure soil dries out between waterings; avoid frequent shallow watering.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a pot with drainage holes; avoid heavy clay soils; topdress with mulch to retain moisture.
Temperature
Prefers warm temperatures (65–85°F / 18–29°C); can tolerate mild frosts but thrives in heat.
Avoid placing near drafty windows or air vents; maintain consistent temperatures; protect from sudden temperature drops.
Fertilizing
every 2–3 months during growing season with balanced fertilizer
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup; stop fertilizing in dormant periods.
Propagation
Methods
Stem cuttings or division; stem cuttings are the most common method.
Step-by-Step Propagation Guide
- Take a 4–6 inch stem cutting.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in moist propagation medium.
- Keep humid and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with bright indirect light; maintain temperatures around 70–75°F (21–24°C).
Medium
Well-draining potting mix (e.g., cactus mix with perlite or sand)
Hormone
Rooting hormone is optional but recommended for faster rooting.
Timeline
Roots typically develop in 2–4 weeks; new growth may appear in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining soil mix, plastic wrap or propagator.
Quick Tips
Use sterile tools to prevent disease; maintain high humidity around cuttings; avoid direct sunlight during rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips to encourage branching; trim stems just above a leaf node or bud.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or damaged stems.
Tools
Pruning shears, sharp scissors, or your fingers for small stems.
Checklist
Use clean tools; prune during active growth; remove dead or diseased parts; shape as desired.
Repotting Guide
Best Season
Spring, before the active growth period begins.
Pot Size
Choose a pot one size larger (1–2 inches wider in diameter) than the current one.
Method
Remove plant gently; trim any circling roots; place in a new pot with fresh, well-draining soil; water lightly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for rejuvenating soil and encouraging growth.
Checklist
Select appropriate pot size; use fresh soil mix; handle roots carefully; water after repotting; place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust frequency seasonally.
How to Apply Water Properly
Water directly at the root zone, ensuring even moisture distribution; water until water drains from the bottom; avoid wetting foliage; water early in the morning or late in the evening to minimize evaporation.
Watering Schedule Tips
Water deeply once every 7–10 days during active growth in spring and summer; reduce frequency to every 2–3 weeks in fall and winter, allowing soil to dry completely between waterings.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for organic matter; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis (yellowing leaves) in cold stress; wilting or scorching in excessive heat.
Cold Stress
Low temperatures slow growth and may cause leaf drop; prolonged cold can lead to root damage.
Solution: Move plants indoors or to a protected area during cold spells; use a heat mat for root protection if necessary.
Hot Stress
Excessive heat can cause leaf scorch, wilting, and reduced vigor; may cease flowering.
Solution: Provide afternoon shade in extreme heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during active growth; avoid over-fertilization; flush soil periodically.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during spring and summer; avoid fertilizing in fall and winter.
