Konni Teak

A distinct natural seed source from the Konni hill forests of Kerala, giving slower-grown, closer-grained, darker and reportedly stronger timber than Nilambur teak — long recognised alongside Nilambur as one of Kerala's two classic named teak seed sources.

About this variety

Konni teak comes from the hill forests around Konni in Kerala, a seed source long recognised alongside Nilambur as one of the state's two classic named teak provenances. Trees grown from Konni seed tend to be slower-growing than Nilambur teak, and this slower growth is associated with closer, tighter grain, a noticeably darker heartwood colour, and timber reported to be stronger and denser — the classic trade-off between growth speed and wood quality seen across many timber species. It remains a smaller, more specialist seed source than Nilambur but is still sought after where strength and grain density matter more than speed of return.

Sowing & cultivation

  • Spacing2 × 2 m to 3 × 3 m at initial planting, thinned progressively over the rotation

Yield & maturity

Maturity period

20+ years, slower early growth than Nilambur

Expected yield

High; valued for strength and density over speed of growth

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.

Pest & disease considerations

Major diseases

  • Not separately documented

Advantages & considerations

Why farmers may choose it

  • Closer, tighter grain and darker heartwood colour than faster-grown teak
  • Reported greater strength and density, valued for high-strength construction and furniture use

Things to consider

  • Slower early growth than Nilambur teak means a longer wait before intermediate thinning income
  • A smaller, more specialist seed source — confirm current availability with Kerala state forest department nurseries
