Care Requirements

Care Difficulty
moderate

moderate

Sunlight

full sun to partial shade

Rotate plant for even light exposure; use sheer curtains to filter intense sun; monitor for signs of sunburn.

Watering

every 7–10 days during active growth, reduce in winter

Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering.

Soil

well-drained, sandy loam with moderate organic matter

pH: Slightly acidic to neutral (pH 6.0–7.0).

Use a mix of potting soil and perlite; avoid heavy clay soils; ensure pots have drainage holes.

Temperature

Prefers cool to moderate temperatures, 60–75°F (15–24°C); tolerates cooler nights.

Avoid sudden temperature fluctuations; protect from drafts; maintain consistent temperatures.

Fertilizing

every 4–6 weeks during spring and summer

Apply fertilizer after watering; flush soil occasionally to prevent salt buildup; reduce feeding in dormancy.

Propagation

Methods

Stem cuttings or division; stem cuttings are more common for home growers.

Step-by-Step Propagation Guide
  1. Take a 4–6 inch cutting.
  2. Remove lower leaves.
  3. Dip in rooting hormone.
  4. Plant in medium.
  5. Keep moist.

Best Time: Early spring or late summer when the plant is actively growing.

Environment

High humidity, indirect light, and warm temperatures (65–75°F).

Medium

Well-draining potting mix with perlite or sand; can also root in water.

Hormone

Optional but recommended for faster rooting.

Timeline

Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.

Tools Needed

Pruning shears, rooting hormone, small pots, misting spray bottle.

Quick Tips

Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat for faster rooting.

Pruning & Repotting

Pruning Guide
Method

Pinch back tips for bushiness; cut just above a leaf node or bud.

Pruning Plan

Prune to maintain shape, encourage bushiness, and remove dead or diseased growth.

Tools

Clean, sharp pruning shears or scissors.

Checklist

Sterilize tools; prune dead/damaged growth; shape the plant; clean up debris.

Repotting Guide
Best Season

Early spring before new growth begins.

Pot Size

Choose a pot 1–2 inches larger in diameter than the current one.

Method

Remove plant gently; trim roots if crowded; place in new pot with fresh soil; water lightly.

Suggestions

Repot every 2–3 years or when roots outgrow the container; beneficial for growth and health.

Checklist

Select new pot; prepare fresh soil mix; handle roots carefully; water after repotting.

Advanced Care Tips

Watering Mastery
Watering Checklist

Check soil moisture; 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; allow excess water to drain away; water in the morning to reduce evaporation.

Pro Tip: Use a watering can with a narrow spout to direct water to the roots without wetting foliage.
Watering Schedule Tips

Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.

Soil Improvement

Add perlite or sand for drainage; incorporate compost for fertility; ensure good aeration.

Temperature Stress Management
Signs of Temperature Issues

Wilting, yellowing leaves, stunted growth, or flower bud drop.

Cold Stress

Slows growth, may cause leaf discoloration or dieback in prolonged cold.

Solution: Provide frost protection; move indoors in freezing temperatures; ensure good air circulation.

Hot Stress

Leaves may wilt, scorch, or drop; growth may slow in excessive heat.

Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.

Fertilizing Guide
Fertilizing Checklist

Check fertilizer type; dilute correctly; apply during active growth; stop in winter.

Fertilizing Method

Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during the growing season; avoid fertilizing in winter.
