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
An easily grown plant, it succeeds in ordinary garden soil[1]. It is adapted to a wide range of soil types, including upland clay, but seems to do best on porous fertile lowlands and river bottoms[269]. It does well on heavy clay soils of relatively high fertility and water holding capacity[269]. Temperatures below 13°C tend to inhibit flowering[269]. For best results, it requires a warm sunny position[1]. The plant is reported to tolerate an annual precipitation in the range of 9 to 429cm, an annual temperature in the range of 8.3 to 27.8°C and a pH of 4.9 to 8.2[269]. This species is not very winter hardy, tolerating occasional temperatures down to about -5°c so long as the soil is not too wet. It is best adapted to warm humid summer-rainfall areas in the subtropics, not growing well in strictly tropical areas[269]. A very aggressive plant[46], spreading freely at the roots and only suitable for large areas[233]. It is a parent of the cultivated Sorghum (S. bicolor)[171]. Classified as a short day plant, it does not flower if the daylight hours exceed about 13 hours per day[269].

Propagation
Seed - sow April in a greenhouse and only just cover the seed. Germination should take place within 2 weeks. Prick out the seedlings into individual pots once they are large enough to handle and plant them out after the last expected frosts. Division in mid spring as the plant comes into new growth. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.
