Pinus massoniana (common name: chinese red pine)

Propagation: It is best to sow the seed in individual pots in a cold frame as soon as it is ripe if this is possible otherwise in late winter. A short stratification of 6 weeks at 4°c can improve the germination of stored seed[1]. Plant seedlings out into their permanent positions as soon as possible and protect them for their first winter or two[2]. Plants have a very sparse root system and the sooner they are planted into their permanent positions the better they will grow[K]. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm[3]. We actually plant them out when they are about 5 - 10cm tall. So long as they are given a very good weed-excluding mulch they establish very well[K]. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance[3].

Cuttings. This method only works when taken from very young trees less than 10 years old. Use single leaf fascicles with the base of the short shoot. Disbudding the shoots some weeks before taking the cuttings can help. Cuttings are normally slow to grow away[4].

Cultivation: Thrives in a light well-drained sandy or gravelly loam[5][2]. Dislikes poorly drained moorland soils[5]. Established plants tolerate drought[3].

This species is an important timber tree in Asia[3].

Plants are strongly outbreeding, self-fertilized seed usually grows poorly[3]. They hybridize freely with other members of this genus[3].

Leaf secretions inhibit the germination of seeds, thereby reducing the amount of plants that can grow beneath the tree[6].

Plants in this genus are notably susceptible to honey fungus[3].

Range: E. Asia - C. and S.E. China.

Habitat: Plains, hills, mountains; near sea level to 2000 m. Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hainan, W Henan, Hubei, Hunan, S Jiangsu, Jiangxi, SE Shaanxi, Sichuan, Taiwan, E Yunnan, Zhejiang[7].

Edibility: A vanillin flavouring is obtained as a by-product of other resins that are released from the pulpwood[3].

Medicinal: The chopped or decocted leaves are used in the treatment of rheumatism and intestinal parasites[8].

The pollen is cardiac and astringent[8].

The turpentine obtained from the resin of all pine trees is antiseptic, diuretic, rubefacient and vermifuge[9]. It is a valuable remedy used internally in the treatment of kidney and bladder complaints and is used both internally and as a rub and steam bath in the treatment of rheumatic affections[9]. It is also very beneficial to the respiratory system and so is useful in treating diseases of the mucous membranes and respiratory complaints such as coughs, colds, influenza and TB[9]. Externally it is a very beneficial treatment for a variety of skin complaints, wounds, sores, burns, boils etc and is used in the form of liniment plasters, poultices, herbal steam baths and inhalers[9].

The wood of the stems is carminative and demulcent[8].

The stem bark is astringent, parasiticide and vulnerary[8].

The root bark is astringent and tonic[8].

Usage: A tan or green dye is obtained from the needles[10].

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[11].

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[12]. The resins are obtained by tapping the trunk, or by destructive distillation of the wood[9][12]. In general, trees from warmer areas of distribution give the higher yields[12]. Turpentine consists of an average of 20% of the oleo-resin[12] and is separated by distillation[9][12]. Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc[9]. 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[9]. Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc.

Wood. An important timber tree in Asia[3], the timber is used for construction, railway sleepers, mine timber, furniture, wood pulp, etc[7].

Pollinators: Wind

Soil: Can grow in light and medium soils.

Drainage: Prefers well drained soil.

In Leaf: Evergreen

Seed Ripens: Mid Winter-Late Winter

Flower Type: Monoecious

Known Hazards: The wood, sawdust and resins from various species of pine can cause dermatitis in sensitive people[13].
