It is considered a naturalized species in southern California and Florida, thriving on wet, swampy soils. It is often found in dense, pure stands.

Difficult Air-Drying under cover and mild kiln drying schedules, as well as a thorough coating of the end-grain with hot wax or glue have been suggested. Kiln Drying Rate Naturally dries at a moderate speed Naturally dries slowly Naturally dries quickly Rapid (<10 days for boards < 32 mm, to <30 days for boards >= 63 mm) Tree Identification Bole/stem form is misshapen Bole/stem form is not buttressed Tree Size Tree height is 30-40 m Sapwood width is 0-5 cm Tree height is 40-50 m Boles are typically crooked and of poor form, which makes the tree undesirable for timber production. Stumps of cut trees are reported to coppice vigorously to produce thickets which are valued commercially for fence posts and landscaping Product Sources Cajeput is described as a general purpose timber within its growing region. It is currently of little commercial importance outside its growing areas Comments General finishing qualities are rated as good Produces little lumber because boles are often of poor form Blunting Effect Little Blunting effect on machining is severe Severe and rapid due to silica Blunting effect on sawing dry wood is severe Blunting effect on machining is fairly severe Boring Easy Carving High silica and density may dull cutters rapidly and severely Carves well in dry condition Cutting Resistance Fairly Difficult to Very Difficult to saw Cutting Resistance with dry wood is easy Cutting Resistance with dry wood is difficult Easy to saw Dulls saw-teeth rather quickly because of high levels of silica. Gluing Easy to glue Good gluing properties Mortising Mortising properties are poor due to interlocked grain Moulding Good finishing results Movement in Service Large Nailing Difficult to nail Planing Fairly Difficult to Very Difficult Easy to plane Planes to a satisfactory finish High density and silicon dulls cutters quickly Difficult to plane Resistance to Impregnation Resistant heartwood Resistant sapwood Heartwood is extremely resistant Response to Hand Tools Easy to Work Fairly Difficult to Difficult to Work Easy to machine Difficult to machine Good response Cutting edges become dull very quickly Routing & Recessing Routing yields good results Sanding Difficult to sand Turning Requires drying before using to prevent warping and checking Good results Veneering Qualities Drying degrade is often moderate to severe, with collapse, buckles, and splilts Moderately easy to veneer Painting Fair to Good Results Good results Polishing Good results Polishes to a smooth surface Varnishing Fair to Good Results Fairly Easy to Very Easy Good results Strength Properties Density (dry weight) = 46-52 lbs/cu. ft.

Bending strength (MOR) = medium Bending strength (MOR) = high Weight = very high Shrinkage, Radial = very small Shearing strength (parallel to grain) = very low Shearing strength (parallel to grain) = high Modulus of Elasticity (stiffness) = medium Density = high Compression strength (parallel to grain) = very high Bending strength (MOR) = very high Leaves contain Cajeput oil which is extracted by steam distillation and is used in the manufacture of soap and also for medicinal purposes. The tree is also a major source of honey.
