Nettle Stand & Log Pile

It is a basic tenet of conservation that certain areas need to be given over to nature. In the Permaculture design, wild areas supply highways into and out of more intensively managed sectors by encouraging predatory insects and birds, self seeding flowers and other ‘blow ins’ which contribute to species diversity and resilience. At the back of the garden, adjacent to the orchard is a nettle stand which had an accompanying log pile from some previous clearance work. Nettle is particularly good for butterfly conservation. It did cross my mind, however, to bring the area into production for food; it has a generous supply of sunlight, and the fact nettles are growing suggests there is a good mineral composition to the soil. 

The soil, however, is full of small rubble and pebbles, and would be difficult to dig, or grow root crops. The sector is also next to a tall (7 ft) breeze block wall, which abuts on to the adjacent farm. Peeking over the wall reveals a disused stables with concrete floor, about half an acre of overgrown waste land, a rusting tractor, and a number of plastic 50 litre containers that appear to have had agricultural chemicals in at some point. Right next to the wall seems to be a storage/ loading bay which may have been used to load up tractors or booms with chemical sprays. As I cannot rule out the containers are from pesticides, and leaching has not occurred, I am disinclined to launch into cultivation of this portion of the garden, preferring to use it as a buffer against a possible contamination source. The sector is some distance from the house, and watering and intensive maintenance tasks would be problematic, applying some zonal thinking to the situation.

Wherever humans have settled, nettles appear. The oldest human latrines, tips, food stores and waste ground have nettles growing on them. They thrive on the nutrient rich waste of humans, and as a result purify the ground and redeem the soil. For now, letting the nettles do their work is satisfactory. If in future this area is to be cultivated, I would suggest shrubs and fruit bushes to accompany the orchard plants and circumvent any problems with digging soil.
