One of the best ways to improve the soil is compost or mulches, but in order to thrive and be healthy plants need extra supplementing nutrients such as Nitrogen, Phosphorus and Potassium, known as NPK. Any fertiliser containing all three of these elements is classed as a balanced fertiliser.
A Guide to Plant Food
Nitrogen (N) is a high priority for leafy plants and vegetables as it stimulates growth and increases the protein content of fruit and leafy edibles, such as cabbage, spinach and lettuce.
When growing vegetables using the annual rotation method by growing plants in different beds each year some edibles naturally supply nitrogen to the soil, like peas and beans, so the following crop in the bed should be a leafy veggies which will benefit from the nutrient-enriched soil.

The addition of potassium (K) to flowers and crops will boost healthy growth. It is essential for photosynthesis, which enables plants to make food for growth, and, in edibles it is necessary as it is stored as starch. Potassium will make plants more resistant to extreme temperatures and drought so should be added to plants in Autumn, especially deciduous fruit trees and roses. Potassium can also be found in manure and wood ash.
When using any fertiliser for the garden it is always very important to read any instructions on the packet as applying too much can have an adverse affect on plants.
