Neem

About

Neem is a fast tropical evergreen tree with compound leaves, sweet-scented flowers, and olive-like drupes whose oil powers organic sprays and traditional medicine. It is not a subtle chemical factory—azadirachtin makes insects rethink their life choices. Marginal in warm outer margins; young trees freeze-kill; older specimens sometimes resprout after light freezes in protected microclimates. True tropical climates onward it becomes a serious shade and windbreak tree. ☀️💧 Sun and Water Requirements: Full sun; deep soil with good drainage; drought-tolerant once established; young trees need consistent moisture to outrun pests. ✂️ Propagation: Seeds (fresh, short-lived); root suckers; grafted selections for uniform chemistry in commercial plantings. 🌾 Harvest / Best Use Timing: Collect drupes for oil processing and traditional preparations when local rules allow—check regulations where self-sowing is a concern.

Permaculture Functions

• Medicinal: Traditional pharmacy tree—verify claims and local rules before scaling use.
• Pest Management: Azadirachtin-rich tissue underpins organic spray ingredients.
• Shade Provider: Broad evergreen canopy for frost-free understory guilds.
• Windbreaker: Fast growth builds windbreak rows where climate stays reliably warm.

Practitioner Notes

• Harvest flowering tops at first full open for many mint-family herbs; past-brown is mulch grade.
• Soil smell and root color tell more than gadget overload—dig a small hole twice a season.
• Weigh small test batches before scaling tinctures—solvent ratio mistakes are expensive at gallon ambition.
• Notebook one weird year—weather anomalies repeat; memory lies, scribbles do not.
