Slash pine is a plant of mainly coastal areas inf the warm temperate and subtropical region of southeastern N. America, but it can also be cultivated in tropical regions at elevations from 500 - 2,500 metres. It grows best in areas where annual daytime temperatures are within the range 23 - 32°c, but can tolerate 8 - 36°c[2]. When dormant, the plant can survive temperatures down to about -5°c, but young growth can be severely damaged at 0°c[2]. It prefers a mean annual rainfall in the range 1,000 - 2,000mm, but tolerates 650 - 2,500mm[2]. Grows best in a sunny position[2]. Succeeds in a wide range of soils, growing best on mesic flatwood sites and on pond or stream margins where soil moisture is ample but not excessive, and drainage is poor[2]. Established stands grow well on flooded sites, but flooding restricts seedling establishment[2]. Established plants are drought tolerant[2]. Prefers a pH in the range 4.5 - 5.5, but tolerant of 4 - 6.5[2]. Tolerant of maritime exposure[2]. A fast growing tree when young, it can live about 200 years[2]. Trees commence producing seed when around 7 - 8 years old[3]. The ovoid to cylindrical seed cones are generally around 9 - 20cm long. They take two growing seasons to mature, shedding their seed whilst still on the tree[4]. Some seeds are produced each year, with good crops about every third year[5]. Annual oleoresin yields of 3 kilos per tree have been recorded from Zimbabwe[3]. Young trees are quite susceptible to fire injury until they are 3 - 4.5 metres tall, but then the bark becomes thick enough to insulate the cambium from high temperatures[3]. The tree has an extensive lateral root system and a moderate taproot[2]. Two geographic varieties exist for this species. The typical Pinus elliottii elliottii is found in the northern part of the range whilst Pinus elliottii densa is only found in southern Florida[2]. Pinus elliottii densa is one of several Pinus species that have a juvenile life stage. After germinating, the seedlings produce secondary foliage but the central shoot does not elongate - at this stage the plant looks more like a bunchgrass than a pine. Especially when growing in shade, the plant can remain in this juvenile stage for several years, developing a large taproot but not increasing in height. If the light levels increase (due to removal of tree cover by fire, deforestation or some other reason) then the plant commences rapid height growth[6].

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[7]. Plant seedlings out into their permanent positions as soon as possible and protect them for their first winter or two[8]. 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[9]. 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[9]. 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[10].
