Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily). Tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate new plants to full sun gradually over 1–2 weeks. Protect from intense midday sun in hot climates to prevent scorching. Indoors, place near a south-facing window.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant weekly for even growth; use sheer curtains in extreme heat; avoid shaded corners.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly until runoff, allow soil to dry partially between waterings, and avoid waterlogging.
Soil
well-drained, fertile loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid overwatering; top-dress with compost annually.
Temperature
Thrives in warm conditions (65–85°F / 18–29°C). Tolerates brief dips to 40°F / 4°C but prefers stable warmth.
Protect from frost; ensure good air circulation; avoid placing near drafty windows or heat vents.
Fertilizing
every 2–3 months during growing season
Fertilize only during active growth; flush soil occasionally to prevent salt buildup; use organic options like compost for slow release.
Propagation
Methods
Stem cuttings or seeds. Stem cuttings are faster and more reliable for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Apply rooting hormone.
- Plant in medium.
- Maintain humidity with a plastic bag or dome.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–80°F / 21–27°C), high humidity (70–80%), and bright indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus potting soil.
Hormone
Recommended to use rooting hormone for faster and more reliable rooting.
Timeline
Roots typically form in 4–6 weeks; new growth may appear in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic wrap or propagation dome, misting bottle.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Selective branch removal to maintain natural form; avoid topping or excessive heading cuts.
Pruning Plan
Shape the tree, remove dead/diseased wood, and encourage a strong framework. Prune to maintain size and improve air circulation.
Tools
Pruning shears, loppers, saw (for larger branches), disinfectant (e.g., rubbing alcohol).
Checklist
Disinfect tools; prune during dormancy; make clean cuts just above buds or branches; remove crossing/rubbing branches.
Repotting Guide
Best Season
Early spring before the active growth period begins.
Pot Size
Increase pot size by 2–3 inches in diameter for young plants; mature trees may stay in the same pot with root pruning.
Method
Remove plant gently; trim roots if necessary; place in new pot with fresh soil mix; ensure drainage holes are clear.
Suggestions
Repot young plants every 2–3 years to refresh soil and accommodate growth. Mature trees may need repotting less frequently if root-bound.
Checklist
Choose appropriate pot size; prepare fresh soil mix; prune roots if needed; water thoroughly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture with a finger; water deeply; ensure drainage; adjust seasonally.
How to Apply Water Properly
Water directly at the root zone, ensuring even saturation to a depth of 6–8 inches. Water early in the morning to minimize evaporation and allow foliage to dry.
Watering Schedule Tips
Water deeply once per week during active growth; reduce frequency to every 2–3 weeks in winter. Adjust based on rainfall and soil moisture retention.
Soil Improvement
Add compost or well-rotted manure for fertility; mix in perlite or sand for drainage; avoid heavy clay soils.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf drop in cold stress; wilting or leaf scorch in excessive heat.
Cold Stress
Growth slows or halts; leaves may yellow or drop; young plants are more susceptible to frost damage.
Solution: Provide frost protection (e.g., burlap wrap) in cold snaps; move potted plants indoors; avoid overwatering in cool conditions.
Hot Stress
Leaf edges may brown or curl; growth may stall; increased susceptibility to pests.
Solution: Provide afternoon shade; increase watering frequency; mist foliage during extreme heat.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; follow dilution rates; apply during growing season; avoid contact with roots.
Fertilizing Method
Use balanced, slow-release fertilizer (10-10-10) in spring and midsummer. Dilute liquid fertilizer to half-strength if needed. Avoid fertilizing in winter.

Humans
Slightly ToxicAlbizia saman, commonly known as the Saman tree, contains toxic compounds primarily in its seeds and pods. Ingestion can lead to mild gastrointestinal distress and other systemic effects due to the presence of toxic alkaloids and other secondary metabolites. The physiological impact is generally limited to mild irritation and discomfort.
