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.

Propagation

Seed - best sown as soon as it is ripe in a cold frame. The seed can be very slow to germinate, stored seed requires 5 months warm then 3 months cold stratification at 5°c[200]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 3cm with a heel, July/August in a frame. Takes 3 weeks. Good percentage[78, 200]. Cuttings of mature wood of the current year's growth, 3cm with a heel, October in a frame. Requires shade. Good percentage[78, 200].
