Now available: PLANTS FOR YOUR FOOD FOREST: 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

Easily grown in any good well-drained soil[1, 200]. Requires a very well-drained poor soil[187]. Prefers a hot dry position[166] and dislikes shade[200]. A very ornamental but short-lived perennial[1], it is hardy to about -10°c[187]. Plants are resentful of root disturbance and should be placed in their final positions as soon as possible[200]. Flowers are produced in the first year from seed[200].

Propagation

The seed can be sown in the middle of spring or in autumn in a cold frame. A period of cold stratification improves germination. As soon as 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[1]. If you have sufficient seed it should be worthwhile trying an outdoor sowing in situ in mid spring[1].
