Improving soil and making compost

•  A hairy nitrogen source

Human hair is by far one of the best nitrogen sources that you can add to your compost heap. Three kilograms of hair contains 450g nitrogen, making it about 25 times as rich as manure. The nitrogen only becomes available when hair breaks down and mineralizes, so it is less useful for fast-growing plants.

• Help from your pet

Sprinkle unused, alfalfa-based feed or bedding onto your compost pile and toss well. Alfalfa, or lucerne, is high in nitrogen — an excellent compost activator — which will help to hasten decomposition.

• Attract earthworms with coffee grounds

The larger the number of earthworms wriggling about in your soil, the better its tilth. Attract the worms to planting beds or other garden areas by digging coffee grounds into the soil.

• Warm up the soil with clear plastic

What free resource will kill weed seeds, most plant diseases and nematodes in your soil? The sun. Till a patch of soil and water it, then lay a sheet of clear plastic over the area (a split-open dry-cleaning bag works well) and anchor the edges with stones. After four to six weeks, the sun’s heat should have rid the soil of most plant menaces.

•  Composting in a leaf bag

Turn autumn leaves into compost by storing them over the winter in large, black plastic leaf bags. When filling the bag with leaves, add a small spadeful of soil and sprinkle with seaweed liquid fertilizer as an activator. Then water sufficiently to ensure all leaves are saturated.

Tie the bag closed and bounce it on the ground a few times to mix the contents. Store the bag in a sunny place so that it absorbs the heat of the sun. By spring the leaves will have rotted into rich compost.
