"Feeding" Your Plants

A fertile soil is a living entity and not simply a conglomeration of chemical elements.
Whilst chemical fertilizers feed plants, organic fertilizers and compost, help to build a healthy fertile soil by stimulating “soil life”, raising the humus status and improving mineralisation, nitrification, cation exchange capacity, soil structure, aeration etc.

Hydroponic Feeding

Hydroponic Feeding
Before making up a nutrient solution, it is essential that the water pH be checked. If the pH exceeds 6,4, acid should be added to the water BEFORE any fertilizer is added.
How much acid to add, depends on the pH and the buffering capacity of the water. Initially add 125ml Nitric Acid per 1000 litres water, gradually adding more until the pH drops below 6,4. Once a rate per 1000 litres is established, a weekly pH check will usually suffice.


Select a site with plenty of morning and afternoon sun. Don’t expect to grow roses on the south side of an avenue of trees or wall. It is too shady.

What do all the numbers on the fertilizer bag mean?

The answer is N - P - K which is an abreviation for the "major nutrients" Nitrogen - Phosphorus - Potassium.
