To reach their full productivity vegetable plants need to be fed. There are several nutrients vital to plant health which encourage leaf growth, root development and help to strengthen the plant's resistance to disease.

These nutrients can be obtained in both organic and inorganic form. The obvious choice for the environmentally-aware gardener is the organic option.

Organic fertilizers will not harm the soil or the micro-organisms in it. In fact the garden will derive long-term benefit from the application of these products. Beware of fertilizers termed "semi-organic" or "organically-based" as they are usually supplemented with chemicals.

Fertilizers are available as liquid, powders or granules. Always read the instructions on the container since some fertilizers, if used incorrectly, can scorch the foliage. Be especially careful when dealing with very young plants.

All of the organic fertilizers below contain:

- Nitrogen for healthy leaf growth.
- Phosphorus for good root growth.
- Potash for resistance to disease.

Seaweed Meal

Apply all year round. especially useful when the soil is warm.

Dried Blood

Very rich in Nitrogen and fast acting. Use up until mid-summer.

Bone Meal

Rich in Phosphate. make sure it is marked "sterilized" and wear gloves when applying.

Fish Meal

Contains Nitrogen and Phosphate. Sometimes sold in "semi-organic" form.

Wood Ash

Make your own. A mulch of woody prunings shredded is a good source or burn unwanted wood and add the ash to your compost bin.

Liquid Seaweed

This contains many trace elements as well as Nitrogen, Phosphorus and Potassium.
