Safety & Hazards
The wood, sawdust and resins from various species of pine can cause dermatitis in sensitive people[1].
Cultivation Details
Pinus aristata is a very cold-hardy plant, able to tolerate temperatures down to around -35°c when fully dormant[2]. Trees grow best in areas with cold dry summers - the largest cultivated specimen is in dry sub-continental north-east Iceland[2]. 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[3, 4]. Dislikes poorly drained moorland soils[3]. Established plants tolerate drought[2]. A wind tolerant tree, it often grows on very exposed ridges in the wild[5]. A very slow growing[6] (to 6 metres in 60 years at Kew) and short-lived tree in Britain, though it lives for 2000 years or more in its native range[4, 7]. This is the oldest known living plant with specimens over 4000 years old[8]. This species is closely related to Pinis balfouriana[4]. The lance-cylindrical seed cones are around 6 - 11cm in diameter, they take two growing seasons to mature, shedding their seeds whilst still attached to the tree and falling soon after[9, 10]. Plants are strongly outbreeding, self-fertilized seed usually grows poorly[2]. They hybridize freely with other members of this genus[2]. Leaf secretions inhibit the germination of seeds, thereby inhibiting the growth of other plants below the tree[11]. Plants in this genus are notably susceptible to honey fungus[2].
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[12]. 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[2]. 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[2]. 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].
