Some plants will require extra nutrition partway through the growing season. This may occur, for example, where the plants are grown on poor soil or in containers. The inorganic gardener has a number of options available to him. Organic gardeners are restricted in their choices, but this is no real handicap. If it is known that a particular crop will require extra feeding, a sprinkling of blood, fish and bone can be made around the roots and lightly hoed in early in the season. Alternatively, or in addition, the use of seaweed fertiliser as a foliar feed will give a much needed boost to leafy vegetables and legumes. For fruiting types, such as squash, tomatoes and so on, a better option would be comfrey liquid, which may be made or purchased in concentrated form for dilution. It is very unlikely that well grown organic crops will require anything further in the way of feeding, although a potassium deficiency may be dealt with quickly by the addition of some freshly prepared (cooled) wood ash, again lightly hoed in around the roots.
