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

Prefers a sunny position in a rich strong loam with abundant moisture at the roots[11, 200]. Succeeds in areas that do not experience prolonged winter temperatures below about -12°c[200], but young plants and the young shoots of older trees can be cut back by winter frosts[11]. Plants are tolerant of compacted soils[200]. The leaves are resinous to the touch and emit a resinous aroma[245]. The root system of this tree is too invasive for small gardens[200]. Plants in this genus are notably resistant to honey fungus[200].
