Gradually acclimate to full sun to prevent scorching; provide shade during peak afternoon heat; adjust placement based on outdoor vs. indoor conditions.
Care Requirements
Care Difficulty
moderateeasy
Sunlight
full sun
Use reflective mulch to enhance light, rotate plant for even exposure, monitor for leaf burn.
Watering
every 3–5 days during active growth, less frequently in dormant periods
Water thoroughly until runoff, allow soil to dry slightly between waterings, avoid wetting foliage.
Soil
well-draining, fertile loam with added organic matter
pH: Slightly acidic to neutral (6.0–7.0).
Use raised beds for better drainage, avoid compacted soil, amend annually.
Temperature
Warm temperatures (70–85°F/21–29°C); intolerant of frost; prefers stable conditions.
Use a thermometer to monitor, avoid drafts, adjust care based on seasonal changes.
Fertilizing
every 2–3 weeks during growing season with balanced liquid fertilizer
Dilute fertilizer to half strength, apply to moist soil, avoid contact with roots.
Propagation
Methods
Seeds or stem cuttings.
Step-by-Step Propagation Guide
- Prepare medium, plant seeds/cuttings, maintain moisture, provide warmth, monitor growth.
Best Time: Spring or early summer when temperatures are warm and stable.
Environment
Warm (75–85°F/24–29°C), high humidity (70–80%), partial shade.
Medium
Well-draining seed starting mix or perlite and peat moss for cuttings.
Hormone
Rooting hormone is optional but recommended for cuttings.
Timeline
Seeds: 7–14 days to germinate; cuttings: 2–4 weeks to root, 2–3 months to establish.
Tools Needed
Seed trays, pots, rooting hormone, misting spray, heating mat.
Quick Tips
Use bottom heat for faster germination, keep soil consistently moist, provide gentle light.
Pruning & Repotting
Pruning Guide
Method
Pinching back tips, cutting above leaf nodes, thinning crowded areas.
Pruning Plan
Remove dead or diseased growth, shape the plant, encourage bushier growth and better fruit production.
Tools
Pruning shears, sharp knife, gloves.
Checklist
Sanitize tools, cut at an angle, remove dead/diseased parts, shape evenly, clean up debris.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 2–3 inches in diameter.
Method
Use fresh well-draining soil, trim roots if necessary, ensure good drainage, water lightly after repotting.
Suggestions
Repot annually or when roots fill the pot; essential for vigorous growth.
Checklist
Prepare new pot, remove plant gently, trim roots, add fresh soil, water lightly, place in shade temporarily.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, avoid wetting leaves, adjust for season.
How to Apply Water Properly
Water directly at the root zone, apply until water drains from the bottom, ensure even moisture without waterlogging, water in the morning for optimal absorption.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add compost, perlite, or sand to improve drainage; use organic matter to enhance fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, bud drop, or leaf burn.
Cold Stress
Growth halts, leaves may turn black or mushy, risk of fungal infections increases.
Solution: Move to a warmer location, use a heat mat, cover with a frost cloth, avoid overwatering.
Hot Stress
Leaf scorch, wilting, reduced flowering, or premature fruit drop.
Solution: Provide shade during peak heat, increase watering, use mulch to retain moisture, ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply to soil, avoid foliage, follow seasonal schedule.
Fertilizing Method
Balanced liquid fertilizer (10-10-10) every 4–6 weeks during growing season; reduce or stop in winter.
