Description: Tree quality and rates of growth and survival were higher in 5- to 8-year-old Australian toon (Toona australis) plantations on sites with deep soils, good drainage, and as or broken pahoehoe rock than in plantations on sites with poor drainage or unbroken pahoehoe rock. Stocking averaged 236 trees per acre. Spacing in initial plants should be about 6 by 7 feet to 8 by 9 feet–depending on expected survival. And during the first few months, weeding and replanting should be done.

Keywords: Toona australis; plantation stand establishment; stocking density; soil factors; Hawaii
