Organic gardeners aim to feed the soil, and let a healthy soil take care of the plants. The best way to add fertility to your garden is to make compost, but in most gardens there is never enough compost to go around and there will be times when supplementary feeding is needed.
An obvious choice is to find a source of animal manure, but this is becoming increasingly difficult – many farmers and stables have realised that their waste products are a valuable resource. And if the animals are not organically raised then there are issues with chemical contamination.
If you do use manure then allow it to compost fully, in a separate heap, for three to six months before using it. Not only does this stabilize the nutrients (so that they’re not washed out by rain), but it also helps to reduce any contamination. Well-rotted manure can be dug into soil or applied to the surface as a mulch. It’s usually possible to buy well-rotted manure and ready-made compost in bags from garden centres.
Cultivating a comfrey patch in your garden can add considerably to its fertility. Comfrey draws up nutrients from the subsoil, and stores them in leaves. Comfrey is a vigorous plant and can be cut several times each year. The leaves are used as a compost activator, as a mulch or to make a liquid feed.
The standard method for making a liquid feed is to cover comfrey leaves in water and leave them for several weeks to decompose. The resulting brew is then watered down before use. However, there’s a real problem with this method – the liquid feeds it produces reek.
A better method is to allow the comfrey leaves to decompose without added water. A bucket with a tap is ideal for this, as it allows you to drain off the finished liquid; the remains of the
