Safety & Hazards
The wood, sawdust and resins from various species of pine can cause dermatitis in sensitive people[1].
Cultivation Details
Pinus halepensis is native to the Mediterranean region, where the summers are hot and dry and the winters cool and moist. It is found in the hotter parts of the region, where brush and forest fires are frequent[2]. The plant is not very cold-hardy, being able to tolerate short periods with temperatures down to around -10°c when fully dormant[3]. Plants become more hardy with age, some older specimens in southern Britain have been known to withstand temperatures down to -17°c without damage[4]. Pine species in general require a sunny position if they are to grow well and, whilst the different species have their own soil preferences, most will thrive in a light well-drained sandy or gravelly loam[5, 4]. Dislikes poorly drained moorland soils[5]. Established plants are very tolerant of drought[6, 7], they succeed in poor chalky soils and also in poor dry sandy soils[8]. Fairly wind-resistant[7]. An average size tree can produce 3 - 4 kilograms of resin per year[3]. The seed cones are 6 - 12cm x 4 - 7cm. They take 3 years to mature and can remain on the branches for several years thereafter without opening. The cones usually only open in very strong summer heat or as the result of the heat from a forest fire[3, 2]. Plants are strongly outbreeding, self-fertilized seed usually grows poorly[7]. They hybridize freely with other members of this genus[7]. Leaf secretions inhibit the germination of seeds, thereby reducing the amount of pants that can grow under the tree[9]. Plants in this genus are notably susceptible to honey fungus[7].
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[10]. Plant seedlings out into their permanent positions as soon as possible and protect them for their first winter or two[4]. 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[7]. 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[7]. 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].
