Highland cardamom plantation shade canopy management: lopping Grevillea branches?

Cardamom (Elettaria cardamomum) requires cool, damp conditions with 50-60% filtered shade to prevent leaf scorch while supporting flower initiation. In highland plantations around Rangala and Corbett’s Gap, estates manage a two-tier shade canopy: high canopy trees (Grevillea robusta / Silky Oak) and intermediate indigenous shade trees (Macaranga peltata / Kenda and Albizia). Pruning occurs in early morning before mountain winds pick up: trained estate workers climb upper canopy branches to lop lateral branches, ensuring diffused sunlight filters down evenly to cardamom clumps without creating hot sunbeams.
