Cultivation Details
The pomegranate is a plant of the subtropical and warm temperate zones. It can also succeed in the less humid areas of the tropics, but fruits less well there. The best quality fruits are grown in dry climates[1]. It grows best in areas where annual daytime temperatures are within the range 23 - 32°c, but can tolerate 8 - 40°c[2]. When dormant, the plant can survive temperatures down to about -10°c, although young growth can be severely damaged at 0°c[2]. It prefers a mean annual rainfall in the range 900 - 1,200mm, but tolerates 400 - 4,200mm[2]. In the temperate zone the main factors affecting its success as a fruit crop are too much moisture and a lack of summer heat - thus although the plant will often succeed as an ornamental in more maritime regions such as western Britain, it will seldom fruit there. Requires a sheltered sunny position[3]. An easily grown plant, succeeding in soils that are light or heavy, and preferring a well-drained fertile soil[4, 5, 6] and succeeds in a hot dry position[7]. Grows poorly in calcareous soils[8]. Tolerant of at least moderate saline levels[9]. Prefers a pH in the range 6.5 - 7.5, tolerating 5.8 - 8.5[2]. Established plants are drought tolerant[9]. Seedling plants can commence fruiting when 3 - 4 years old[8]. Yields may be about 100 - 200 kilos of fruit per fully developed tree per year, which is about 50 - 200 fruits per tree or up to 10 tonnes per hectare[2] Most plants of this species grown in cooler and moister regions of the temperate zone are likely to be the dwarf cultivar 'Nana'. This is hardier than the type but its fruit, even if produced, is not such good quality[10]. This sub-species fruited on an east-facing wall at Kew in the hot summer of 1989[PFAF]. Flowers are produced on the tips of the current years growth[11]. Plants often sucker freely[12]. There are many named varieties[13]. Plants in this genus are notably resistant to honey fungus[11].
Propagation
Seed - sow spring in a greenhouse, preferably at a temperature of 22°c[11, 14]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for at least their first 2 growing seasons. Plant out in late spring or early summer. Cuttings of half-ripe wood, 4 - 5cm with a heel, early summer/July in a frame[15, 16]. Good percentage[15]. Cuttings of mature wood, 20 - 25cm long, late autumn in a warm greenhouse[16]. Layering. Division of suckers in the dormant season[11]. They can be planted out direct into their permanent positions, though we prefer to pot them up first and plant them out when they are growing away well in late spring or early summer.
