Safety & Hazards
The wood, sawdust and resins from various species of pine can cause dermatitis in sensitive people[1].
Cultivation Details
Pinus banksiana is a plant of boreal to subarctic regions, growing up to where the Arctic tree line merges with the tundra. It occurs mainly in continental climate conditions with short, warm summers, and long, very cold winters and low precipitation, about half of whch is snow[2]. It is a very cold-hardy plant, able to tolerate temperatures down to around -40°c when fully dormant[3]. It grows best in climates where there is a distinct transition from winter to spring. It is easily excited into growth as the season warms up and, in areas where periods of mild weather can be interspersed with a return to cold conditions, this new growth is very susceptible to damage by temperates near to or below freezing[2]. Thrives in a light well-drained sandy or gravelly loam[4]. It grows mostly on dry, sandy soils but is also found on thin soils over granite or metamorphosed rock and on peat[2]. Dislikes poorly drained moorland soils and shady positions[4]. Starts away well on almost any soil, whether poorly drained or shallow and dry[5]. Established plants tolerate drought[3]. A fast growing tree when young[3], but growth soon slows down and the tree is short-lived in Britain with no tree known to be older than 75 years[5]. New shoots can be almost 1 metre long, though the tree remains spindly[5]. An open-topped tree, though plants sometimes have a shrubby habit of growth[6]. They can start producing seed when only a few years old[6]. The cones are 4- 5cm long[6]. They ripen in their second year and sometimes shed their seeds at this stage, but the cones can remain un-opened on the tree for a number of years, opening and shedding their seed after several years or after a forest fire has heated them to at least 50°c[7, 8]. This latter habit makes them one of the first colonizers of burnt land[7]. The plant is highly adapted to fires, which are frequent in the taiga forests and can destroy vast areas of forest cover. Indeed, Jack pine is the most successful coniferous pioneer after fire, where its seedlings can be found growing with Betula papyrifera or Populus tremuloides[2]. Plants are strongly outbreeding, self-fertilized seed usually grows poorly[3]. They hybridize freely with other members of this genus[3]. This species hybridises in the wild with the closely related Pinus contorta where their ranges overlap[7, 8]. There are several named varieties selected for their ornamental value[3]. Leaf secretions inhibit the germination of seeds, thereby inhibiting the growth of other plants below the tree[9]. Plants in this genus are notably susceptible to honey fungus[3].
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[11]. 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[12].
