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 moderately fertile well-drained soil in full sun or light shade[200]. The plants produce flowers and fruits better when they are growing in full sun[200]. Hardy to about -20°c[184]. This species is closely allied to P. sinensis[11, 109]. Flowers are produced very early in the spring and they are then easily damaged by frosts[11]. The flowers are produced on the previous seasons wood[200]. They are produced on old wood according to another report[182]. Plants only fruit in Britain after long hot summers[200].

Propagation

Seed - best if given 2 months cold stratification[113]. Sow the seed in autumn if possible, otherwise in late winter or early spring in a cold frame in light shade. Germination may be inhibited by light[113]. Prick out the seedlings when they are large enough to handle into individual pots. Grow them on in a greenhouse or cold frame for their first winter and plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, July/August in a frame[113].
