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.

Propagation

Seed - we have no information for this species but suggest sowing the seed in a pot that is standing in its own depth of water in a greenhouse as soon as the seed is ripe if this is possible. Stored seed is likely to have a short viability. Prick out the seedlings when they are large enough to handle and increase the depth of water around the pot until the plants are covered by a few centimetres of water. Grow the plants on in a sunny position in the greenhouse for their first winter, increasing the depth of water as the plants grow larger. Plant them out into their permanent positions in early summer. Division in spring[56]. Cuttings of erect shoots in the growing season[56].
