Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day) with tolerance to partial shade in hot climates. Adjust exposure based on seasonal light intensity.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh afternoon sun in summer; ensure adequate light indoors if grown as a container plant.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Rotate pots for even light exposure; use sheer curtains to filter intense sun; place outdoor plants in morning sun, afternoon shade.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but infrequently; ensure soil dries slightly between waterings; avoid waterlogging.
Soil
well-draining, sandy loam with moderate organic content
pH: 6.0–7.5 (slightly acidic to slightly alkaline).
Ensure pots have drainage holes; avoid heavy clay soils; use mulch to retain moisture and suppress weeds.
Temperature
Prefers cool to moderate temperatures (60–75°F or 15–24°C). Tolerates mild frosts but may struggle in extreme heat.
Avoid sudden temperature fluctuations; protect from frost; water early to reduce heat stress.
Fertilizing
every 4–6 weeks during spring and summer
Apply fertilizer after watering to prevent root burn; stop feeding in dormant periods; use a balanced formula for steady growth.
Propagation
Methods
Stem cuttings or division. Stem cuttings are the most common method for home growers.
Step-by-Step Propagation Guide
- Take 3–4 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in moist medium.
- Maintain humidity.
- Transplant once rooted.
Best Time: Late spring to early summer when the plant is actively growing.
Environment
Warm (65–75°F or 18–24°C), humid, and bright but indirect light. Protect from direct sun and drafts.
Medium
Well-draining potting mix, such as a mix of peat, perlite, and sand.
Hormone
Optional, but rooting hormone can speed up root development.
Timeline
Roots typically develop in 2–4 weeks; plants can be transplanted after 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining soil mix, plastic bags or propagation dome.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips to encourage branching; deadhead spent flowers; trim leggy stems to maintain compact growth.
Pruning Plan
Regular light pruning to maintain shape and encourage bushier growth. Remove spent flowers to prolong blooming.
Tools
Pruning shears, sharp scissors, gloves.
Checklist
Clean tools before use; prune dead or damaged stems; remove spent flowers; shape as desired.
Repotting Guide
Best Season
Early spring, before the active growing season begins.
Pot Size
One size up from the current pot (e.g., from a 4-inch to a 6-inch pot).
Method
Remove the plant gently; trim any circling roots; place in a slightly larger pot with fresh, well-draining soil; water thoroughly after repotting.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound. Container-grown plants may need repotting annually.
Checklist
Choose a new pot with drainage holes; prepare fresh soil mix; handle roots carefully; water after repotting; place in a shaded area for a few days.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone. Water early in the morning to minimize evaporation and fungal issues. Allow excess water to drain away.
Watering Schedule Tips
Water deeply once a week during active growth; reduce frequency in winter to every 2–3 weeks. Adjust based on rainfall and soil dryness.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility; adjust pH with lime (to raise) or sulfur (to lower).
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or stunted growth in excessive heat; yellowing or browning leaves in cold stress.
Cold Stress
Low temperatures slow growth and may cause leaf discoloration or dieback, especially if prolonged or coupled with wet soil.
Solution: Provide frost protection in winter; ensure good drainage to prevent root rot; move container plants indoors if temperatures drop below 20°F (-6°C).
Hot Stress
Excessive heat can lead to wilting, flower drop, and reduced vigor, especially if combined with drought stress.
Solution: Provide afternoon shade; increase watering frequency; use mulch to retain soil moisture; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer label for dilution rates; fertilize during active growth; avoid over-fertilization.
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.
