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

Landscape Uses:Christmas tree, Firewood, Aggressive surface roots possible, Screen, Specimen. An easily cultivated, fast-growing tree[81], it prefers a deep rich soil and a sunny sheltered position[1, 11, 81]. Thrives in any soil, site or exposure[81] including a hot dry position. Tolerates light shade only when very young[200], older plants strongly dislike shade[11]. Does not thrive on shallow chalk[200]. Established plants are drought resistant[200]. Dislikes atmospheric pollution[200]. This species is the biggest (but not the tallest) tree in the world[81] and can weigh up to 2000 tonnes[185, 200]. It is also a very long-lived tree in the wild, specimens have been found that are 3500 years old[81]. Fairly fast growing in height in Britain, annual increases of 60cm for the first 50 years or more are common[185]. Increase in girth can be spectacular, 7 - 10cm a year being the average[185]. Trees appear to be long-lived in Britain[185]. Best planted into its permanent position when no more than 30 - 50 cm tall[200]. Trees are notably susceptible to honey fungus[81, 200]. The foliage is hard and harsh to the touch and readily emits a scent of aniseed[185]. Cones take 2 years to mature[82]. In its native habitat the cones are retained on the tree with viable seed for up to 30 years[185]. The cones open after the heat of a forest fire[200]. Special Features: Attracts birds, North American native, Inconspicuous flowers or blooms.

Propagation

Seed - sow early spring in a cold frame in light shade. Seed can also be sown as soon as it is ripe in a greenhouse. Germination rates are usually very low[11], two months cold stratification might help[113]. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in a cold frame for their first winter, planting them out into their permanent positions in late spring or early summer. Plants will require some protection from cold and spring frosts for their first year or two outdoors[78]. If there are sufficient seeds, they can be sown in a lightly shaded outdoor bed in late March[78]. Grow them on for two years in the seed bed before planting them out into their permanent positions in late autumn or early spring.

I recently picked up a packet of sequoiadendron seeds from Kew Gardens in London. Following the instructions on the packet, I put them in the fridge (dry) for 10 days, then soacked them in water for 48 hours, then sowed on top of moist compost in small seedling pots and covered with clingfilm to keep damp. The seeds were kept in a bright conservatory out of direct sunlight at around 25 Celsius during the day. Seeds began to germinate after 7 days. By 17 days, over 50 % had germinated. As soon as the seed shell has fallen off to reveal several green needles, I take from under the cling film to prevent mold. All seem to be thriving. The instructions read that there should be no direct sunlight for the first 6 weeks and that the seedlings can be carefully repotted at 5-8 weeks.
