Growth—

Pinus occidentalis is found on the island of Hispaniola, where it grows in a wide range of elevations, from around 200 - 3,200 metres. The climate is tropical , but at elevations above 1,600 - 1,800 metres there can be frosts in the cool season and rarely snow. The mean annual precipitation is generally within the range 1,200 - 1,600mm, but can reach 2,300mm in parts of its range. There is a 3 - 5 month dry season during the cool season[2]. The plant requires a sunny position. It is found mainly in nutrient-poor, often shallow soils and rocky outcrops, which can be derived from limestone or more acid clays[2]. Plants in this genus are notably susceptible to honey fungus[3].

Propagation

It is best to sow the seed in individual pots as soon as it is ripe if this is possible. A short stratification of 6 weeks at 4°c can improve the germination of stored seed[4]. Plant seedlings out into their permanent positions as soon as possible[5]. Plants have a very sparse root system and the sooner they are planted into their permanent positions the better they will grow[PFAF]. 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[PFAF]. 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[6].
