Sunlight for নিম?

Full sun. Neem demands open, unshaded exposure for vigorous growth and heavy flowering. Juvenile plants tolerate light partial shade but canopy development stalls without direct sun.

Low once established. Young saplings need regular irrigation during the first 1–2 dry seasons to develop a taproot. Mature trees are highly drought-tolerant and suffer root rot in waterlogged soils.

Well-drained, tolerant of poor soils. Grows on sandy loams, stony slopes, and degraded alluvium, with a preference for neutral to slightly alkaline pH. Avoid saline, waterlogged, or heavy clay sites.

Temperature for নিম?

21–40 °C; frost-sensitive. Optimum tropical to subtropical range; withstands prolonged heat exceeding 45 °C once mature. Sustained temperatures below 4 °C damage foliage and young wood.

What is নিম used for medicinally?

Leaf decoctions used in Ayurveda and Unani traditions for skin conditions, fevers, and as a blood purifier; Seed oil (rich in azadirachtin and nimbin) applied for dermatitis, scabies, and fungal infections; Twigs traditionally chewed as datun for oral hygiene and gum health across South Asia; Bark extracts used in traditional formulations for malarial fevers and intestinal parasites
