Unless you live in a very high rainfall area water is going to be an issue for you if you are to maintain a food garden.
When planting out a garden many people do not consider the water needs of their plants, often putting plants with both high and low water needs side by side.
If you do this then to provide the right amount of water you will have to water each plant individually, which is very time consuming. If you water them as an entire section you will be either over watering plants that don't need much water or under watering those that need a lot .
So it is a good practice to group plants together that have similar water needs as this makes it easier for you to supply the right amount of water to them. This is best done by grouping them into three different water zones :-
working out the sizes for each water zoneHow big each water zone is will depend on :-
- Your annual rainfall.
- The total size of your garden.
- The number and size of your water tanks.
- The size of the roof/s that the water tanks are attached to
multiple water zone areasOf course it would be unlikely that you would divide your garden up into just three water zone areas as this would be impractical. I have multiple water zone areas throughout my garden, some as little as just a few metres (yards) square while others, usually the dry zone areas, are quite large. These water zones also cross the boundaries of my Garden Zones.
