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.

Summary


Physical Characteristics

 icon of manicon of cone
Casuarina torulosa is an evergreen Tree growing to 15 m (49ft 3in).
It is hardy to zone (UK) 9. It is in leaf all year. The species is dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). .
It can fix Nitrogen.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil.

Cultivation details

Requires a well-drained moisture-retentive soil in full sun[200]. Succeeds in most soils and aspects in Australian gardens[157]. Tolerates temperatures down to at least -7°c in Australian gardens[157] although this cannot be translated directly to British gardens due to our cooler summers and longer, colder and wetter winters. It experiences frost and snow in parts of its native range and so some provenances should succeed outdoors at least in the mildest areas of the country[K]. This species has a symbiotic relationship with certain soil micro-organisms, these form nodules on the roots of the plants and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[157, 200]. A dioecious species, at least one male plant is required for every 5 - 6 females in order to produce seed[265]. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is suckering with new plants from underground runners away from the plant [2-1].

Propagation

Seed - sow late winter to early summer in a greenhouse and only just cover the seed[138]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a 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, July/August in a frame[157, 200].
