Urtica dioica, Nettles are one of the most undervalued economic plants. They have a wide range of uses for food, medicines, and fibres and are also significant plants for wildlife. At least 30 species of insects feed on them, and the caterpillars of several Lepidoptera species depend on them for food. Nettles are a very nutritious food that is easily digested and is high in minerals (iron) and vitamins (A and C). Young leaves are cooked as a potherb and added to soups. They can also be dried for

Industrial Crop: Fiber Management: Hay Regional Crop Staple Crop: Protein Prefers a soil rich in phosphates and nitrogen. Plants must be grown in a deep rich soil if good quality fibre is required[4, 115]. Nettles are one of the most undervalued of economic plants. They have a wide range of uses, for food, medicines, fibres etc and are also a very important plant for wildlife. There are at least 30 species of insects that feed on it and the caterpillars of several lepidoptera species are dependant upon it for food. Especially when growing in rich soils, the plant can spread vigorously and is very difficult to eradicate. It is said that cutting the plant down three times a year for three years will kill it. It is a good companion plant to grow in the orchard and amongst soft fruit[53, 54]. So long as it is not allowed to totally over-run the plants, it seems to improve the health of soft fruit that grows nearby and also to protect the fruit from birds, but it makes harvesting very difficult. Dioecious. Male and female plants must be grown if seed is required. The plant is heat tolerant in zones 10 through 1. (Plant Hardiness Zones show how well plants withstand cold winter temperatures. Plant Heat Zones show when plants would start suffering from the heat. The Plant Heat Zone map is based on the number of "heat days" experienced in a given area where the temperature climbs to over 86 degrees F (30°C). At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 (no heat days) to 12 (210 or more heat days). For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a runner spreading indefinitely by rhizomes or stolons [1-2]. The root pattern is fibrous dividing into a large number of fine roots [1-2]. The root pattern is rhizomatous with underground stems sending roots and shoots along their length [1-2]. The leaves and young shoots are typically harvested in spring, before flowering, from early spring to late spring. Stinging nettle usually flowers from late spring to summer, around June to August (Northern Hemisphere). Stinging nettle grows quickly and can reach its full height within a single growing season, making it a vigorous and robust plant. Carbon Farming Industrial Crop: Fiber Clothing, rugs, sheets, blankets etc. Currently, almost none of our fiber are produced from perennial crops but could be! Management: Hay Cut to the ground and harvested annually. Non-destructive management systems maintaining the soil organic carbon. Regional Crop These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits. Staple Crop: Protein (16+ percent protein, 0-15 percent oil). Annuals include beans, chickpeas, lentils, cowpeas, and pigeon peas. Perennials include perennial beans, nuts, leaf protein concentrates, and edible milks.

Edible Parts: Leaves Oil Shoots Edible Uses: Colouring Curdling agent Drink Oil Young leaves - cooked as a potherb and added to soups etc[1, 2, 9, 12, 13, 36, 183]. They can also be dried for winter use. Nettles are a very valuable addition to the diet, they are a very nutritious food that is easily digested and is high in minerals (especially iron) and vitamins (especially A and C)[4, 201, 238]. Only use young leaves (see the notes above on toxicity) and wear stout gloves when harvesting them to prevent being stung. Cooking the leaves, or thoroughly drying them, neutralizes the sting, rendering the leaf safe to eat[4, 244]. The young shoots, harvested in the spring when 15 - 20cm long complete with the underground stem are very nice. Old leaves can be laxative. The plants are harvested commercially for extraction of the chlorophyll, which is used as a green colouring agent (E140) in foods and medicines. A tea is made from the dried leaves, it is warming on a winters day[21, 183]. A bland flavour, it can be added as a tonic to China tea. The juice of the leaves, or a decoction of the herb, can be used as a rennet substitute in curdling plant milks. Nettle beer is brewed from the young shoots. References More on Edible Uses

Seed - sow spring in a cold frame, only just covering the seed. Prick out the seedlings into individual pots when they are large enough to handle, and plant them out in the summer. Division succeeds at almost any time in the growing season. Very easy, plant them straight out into their permanent positions.
