This species is Successfully grown in Wet & intermediate zone between 600m

is graded under Class II timber grading in State Timber Corporation timber
grading system. The wood is pinkish- brown in colour. Timber also has characteristic
fragrant, nice grain patterns and it is easy to work with.
Our Toona plantation is located in Haputale, within the
climatic zone of up country wet zone. Total Extent of the plantation is 50 ha. When consider about management prescriptions of the
plantation, plant seeds do not need pretreatment. Seeds should be sowing in
nursery and allowed to grow upto 0.6-1.2 m height prior to planting in field. Grevillea robusta is planting 2 years
prior to planting Toona as a shade tree and will be removed after 8 years of
planting. Then Cocoa and Anthurium is going to intercrop with Toona for maximum
land utilization. The end product will be timber logs which will be sold out to
local buyers and saw mills.
