The needles contain a substance called terpene, this is released when rain washes over the needles and it has a negative effect on the germination of some plants, including wheat. Oleo-resins are present in the tissues of all species of pines, but these are often not present in sufficient quantity to make their extraction economically worthwhile. The resins are obtained by tapping the trunk, or by destructive distillation of the wood. In general, trees from warmer areas of distribution give the higher yields. Turpentine consists of an average of 20% of the oleo-resin and is separated by distillation. Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc. Rosin is the substance left after turpentine is removed. This is used by violinists on their bows and also in making sealing wax, varnish etc. Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc.Wood. An important timber tree in warm temperate areas.

This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c. Plants usually form multi-stemmed trees in Britain due to frost damage. Early growth is quite rapid but, in England, once trees reach a good size they blow down or die. This species is cultivated for its timber in warm temperate areas but is not very suitable for Britain. Plants grow well in Cornwall (where there are specimens more than 15 metres tall) and in other areas with similar climates. The cones open and shed their seed whilst still attached to the tree. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. Leaf secretions inhibit the germination of seeds, thereby reducing the amount of plants that can grow under the trees.This species is notably resistant to honey fungus.
