Cultivation Details

Castanopsis species are generally tolerant of a range of soils, preferably well-drained[]. They succeed in full sun, though young plants generally grow best in dappled woodland shade.
The tree does not respond well to coppicing[].

Edible Uses

Seed - raw or cooked[]. The ovoid to conical seed is 15 - 25mm long and 15 - 20mm wide with a thin shell; there are 2 - 3 equally developed seeds in each cupule[].
The seed is usually cooked before eating, though it can also be eaten raw. It can be eaten whole, though it is more commonly dried, then ground into a powder and used as a thickening in stews etc or mixed with cereals for making bread.
The main disadvantage of the seed is that it is often rich in tannins, making it bitter and astringent. These tannins can be largely removed by soaking the seeds in water then throwing the water away. The process should be repeated until the seed no longer tastes bitter.

Medicinal

None known

Other Uses

The bark is a source of tannins and can be used as a dye, to weatherproof fibres etc[].

The branches and stems of many Castanopsis species are used as bed logs in mushroom cultivation[].

The sapwood is white[].
The heartwood is dark brown or dark red-brown; it is clearly demarcated from the light brown sapwood which often has a green tinge. The texture is coarse and uneven; the grain fairly straight but sometimes interlocked, maybe lustrous when first cut; there is no distinctive odour or taste when dry. The wood is strong, moderately hard, moderately heavy to heavy, moderately durable and very difficult to treat. It seasons fairly slowly, without any defects except for some staining; shrinkage is very high. It is easy to work, easy to split, moderately easy to resaw and easy to cross-cut; planning is easy and the planed surface is smooth, it takes a good finish. A light hardwood, it is suitable for medium to heavy construction under cover, furniture making, packing cases and pallets. Some species split well and are used for shingles[, ].
The wood is a good fuel and can be used to make charcoal[].

Propagation

Seed - easy to germinate if sown fresh. Self-sown seedlings can be transplanted[].
