Cultivation Details
Arbutus menziesii is restricted in the wild to areas having mild oceanic winters; however, temperature and moisture regimes vary considerably throughout its range. It is considered to be hardy to about -10°c, though it can be damaged or even killed if it endures long periods of frost or severe frost at around -10 °c. Mean annual precipitation may range from 380 - 4,220mm, mostly as rain..Temperature extremes are from -21 to 46°c, Trees succeed outdoors at Kew but shoots of young plants are apt to be cut back in winter[1]. They grow very well in S.W. England[1]. Requires a lime-free nutrient-rich well-drained moisture-retentive soil in sun or semi-shade and shelter from cold drying winds, especially when young[2]. Succeeds in a limy soil according to another report[3]. Established plants are drought tolerant[4]. An ideal plant for the small garden or as a lawn specimen, it has a neat, compact, upright growth habit, retaining its lower leafy branches close to the ground and casting little shade[5]. The flowers have a honey-like fragrance which will pervade the whole garden on calm days[5]. Trees are slow-growing in the wild, living up to 225 years[6], though they are fairly fast growing in cultivation when young[1]. They dislike being transplanted and should be placed in their final positions as soon as possible[1, 7, 8]. Give them some protection in their first winter outdoors. Plants can resprout from the base if coppiced or cut back by fire[4]. This species is notably resistant to honey fungus[2].
Propagation
Seed - best surface sown in a cold frame as soon as it is ripe. Stored seed should be soaked for 5 - 6 days in warm water and then surface sown in a shady position in a greenhouse[9]. Do not allow the compost to become dry. Six weeks cold stratification helps[7]. The seed usually germinates well in 2 - 3 months at 20°c[7]. Seedlings are prone to damp off[10], they are best transplanted to individual pots as soon as they are large enough to handle and should be kept well ventilated. Grow them on in a greenhouse for their first winter and then plant out in late spring after the last expected frosts[PFAF]. The plant has long-term seed dormancy and viability and stays viable for 'scores' of years in the soil. When conditions are right (i.e., cool temperatures and adequate moisture), after-ripening is induced and dormancy is broken[4]. Basal cuttings in late winter[2]. Very difficult to root successfully[11]. Cuttings of mature wood of the current season's growth, late autumn in a frame. Poor percentage[9]. Layering of young wood - can take 2 years[12, 2].
