Safety & Hazards

The sawdust, the resin from the trunk and even the needles can cause dermatitis in some people[1].

Cultivation Details

HabitEvergreen Tree
GrowthFast

Likes abundant moisture at the roots, if grown in drier areas it must be given a deep moist soil[2]. Tolerates poor peaty soils[3]. Succeeds in wet cold and shallow soils but is not very wind-firm in shallow soils[4]. Resists wind exposure to some degree[3]. A shallow-rooted tree, in the wild it is often blown down by strong winds[5]. Prefers a pH between 4 to 6[3]. Dislikes shade[3]. Intolerant of atmospheric pollution[2]. This species has been planted experimentally as a timber crop in N. Europe[6]. It is slow to get started, but can then grow fairly rapidly when established though it soon slows down and seems to be fairly short-lived in cultivation, around 100 years is probably the limit[7]. Wild trees live about 300 - 400 years[5]. In some upland areas, especially over granitic or other base-poor soils, growth rate and health have been seriously affected by aluminium poisoning induced by acid rain[3]. Seed production commences when the tree is about 15 years old, though reliable crops are not produced for another 5 - 10 years[5]. Heavy crops occur every 4 - 6 years[5]. Plants are strongly outbreeding, self-fertilized seed usually grows poorly[3]. They hybridize freely with other members of this genus[3]. Closely related to and hybridizes in the wild with P. mariana[5]. It is believed by some botanists to be a hybrid between P. mariana and P. glauca[8]. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance[3]. The crushed leaves are redolent of apples or camphor[7].

Propagation

Seed - stratification will probably improve germination so sow fresh seed in the autumn in a cold frame if possible[9]. Sow stored seed as early in the year as possible in a cold frame[10]. A position in light shade is probably best[10]. Seed should not be allowed to dry out and should be stored in a cool place[9]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first winter. They can be planted out into their permanent positions in early summer of the following year, or be placed in an outdoor nursery bed for a year or so to increase in size. They might need protection from spring frosts. Cuttings of semi-ripe terminal shoots, 5 - 8cm long, August in a frame. Protect from frost. Forms roots in the spring[10]. Cuttings of mature terminal shoots, 5 - 10cm long, September/early autumn in a cold frame. Takes 12 months[10]. Cuttings of soft to semi-ripe wood, early summer in a frame. Slow but sure.
