Care Details
Ideal Sunlight Coverage:
Full sun to partial shade (6–8 hours of direct sunlight daily); tolerates some afternoon shade in hot climates.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh midday sun to prevent scorching; adjust placement based on outdoor vs. indoor conditions.
Care Requirements
Care Difficulty
very easyeasy
Sunlight
full sun to partial shade
Rotate plants for even light exposure; use sheer curtains to filter intense sun; monitor for signs of sunburn.
Watering
every 3–5 days during active growth, reduce in winter
Water at the base of the plant to avoid foliage wetting; ensure soil dries between waterings; adjust frequency based on season and weather.
Soil
well-draining, loamy soil with moderate organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Avoid heavy clay soils; ensure good aeration; test pH if issues arise.
Temperature
Prefers moderate temperatures (60–75°F or 15–24°C); thrives in cool to warm conditions with protection from extreme heat or frost.
Use shade cloth in summer; protect from frost in winter; maintain consistent temperatures for best growth.
Fertilizing
every 4–6 weeks during growing season
Apply fertilizer after watering to prevent root burn; use organic options like compost tea for gentle feeding; stop fertilizing in late fall.
Propagation
Methods
Stem cuttings or seed; stem cuttings root easily in warm conditions.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings below a node.
- Remove lower leaves.
- Dip in hormone (if used).
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when temperatures are mild and growth is active.
Environment
Warm (70–75°F or 21–24°C), humid (60–70%), and bright indirect light with some air circulation.
Medium
Well-draining potting mix (e.g., peat-based with perlite) or perlite/vermiculite for cuttings.
Hormone
Optional but recommended for faster rooting; use a mild rooting hormone powder or liquid.
Timeline
Roots typically form in 2–3 weeks; plants may be ready to transplant in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium, misting bottle.
Quick Tips
Use sterile tools to prevent disease; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back stems or snip off spent flowers just above a leaf node.
Pruning Plan
Light pruning to maintain shape and encourage bushier growth; remove spent flowers to prolong blooming.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sterilize tools; prune in early morning; remove dead or damaged growth; avoid over-pruning.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter); ensure good drainage holes.
Method
Remove plant gently; trim any circling roots; place in a slightly larger pot with fresh, well-draining soil; water lightly.
Suggestions
Repot annually or when roots fill the pot; beneficial for container-grown plants to refresh soil and space.
Checklist
Choose appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water early morning; avoid wetting leaves; ensure proper drainage.
How to Apply Water Properly
Water deeply at the root zone until soil is moist but not waterlogged; avoid overhead watering to reduce fungal risk; water early in the day to allow foliage to dry.
Watering Schedule Tips
Water lightly and frequently during active growth, reducing frequency in winter dormancy; allow soil to dry slightly between waterings to prevent root rot.
Soil Improvement
Add compost or well-rotted manure for fertility; mix in perlite or sand for drainage; ensure organic matter is well-integrated.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in excessive heat; leaf drop or browning in cold stress.
Cold Stress
Low temperatures slow growth and may cause leaf damage or death; frost can be lethal.
Solution: Provide frost protection (e.g., row covers); move potted plants indoors; avoid overwatering in cold conditions.
Hot Stress
Excessive heat can lead to wilting, flower abortion, and reduced vigor; may bolt prematurely.
Solution: Provide shade during peak heat; increase watering frequency; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer label for NPK ratio; dilute correctly; apply to moist soil; avoid contact with foliage.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during growing season; avoid fertilizing in winter.
