Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details

Succeeds in any well-drained moderately fertile soil in full sun[182, 200]. Thrives in a chalky soil[182] but prefers a light loam or peaty soil[11]. Very tolerant of maritime exposure[75, 200] and atmospheric pollution[182, 200]. A very ornamental plant[1], it is hardy to about -15°c[184], succeeding outdoors at Kew but liable to be cut back to the ground in severe winters[11]. It is perfectly hardy, however, in the mild maritime areas of Britain[200]. Plants flower best in years that follow long hot summers[200]. Can be pruned right back into old wood in order to promote fresh growth[200]. Any pruning is best done in the spring[11]. It is best to trim new growth of young plants by 50% each year for the first three years after planting in order to promote basal shoots[29].

Propagation

Seed - surface sow in early spring in a greenhouse. Do not allow the compost to dry out. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first winter. If growth has been sufficiently good, plant them out into their permanent positions in early summer of the following year, otherwise grow them on for another year in pots and plant them out the following early summer. This species is a hybrid and so will not breed true from seed. Cuttings of half-ripe wood, 5 - 10cm with a heel, July/August in a frame. Pot up in late August and overwinter in a cold frame then plant out in late spring or early summer[78]. Good percentage[11]. Cuttings of moderately ripe wood of the current years growth, 5 - 10cm with a heel, November in a frame. High percentage[78].
