Commercial plantations should be on gentle slopes on well drained soils with good aeration. Extensive clearing, often accompanied by burning, is required to prepare the sites. In the sapling period, opening in the canopy are needed for further successful growth. In plantation of A. dammara in Java (with initial spacing of 3m x 3m), the first thinning is often at the age of 6 years, and than every 3 years until then the age of 20 years and every 5 years afterwards. Young trees seem to be sensitive to competition from the grass and also to over growing by vines, so young plantation must be weeded.
