Vegetable gardens need to be sited in an open sunny spot away from large trees with invasive roots such as the African Mahogany tree (Khaya). Raised beds are good to use as they allow wet season rain to drain away and are easier to control weeds from getting into veggie crops. A gap of 60 - 80cm must be kept between beds to allow wheelbarrow access. Plants that are susceptible to sunburn such as lettuce and rock melon can be grown in half shade. The best size beds are at least 3m long and 2m wide. The beds only need to be 30-40cm high. Do not use cardboard or newspaper as the bottom layer as this will attract white ants.
Example of garden layout with raised beds, fruit trees and fence
If raised beds are too expensive make long drills with the soil raised up in a long mound 15cm high and 30cm wide. Space rows 60cm apart. This will help with drainage and make it easier to control weeds. Plants can be placed in a shallow hole on top of the mounded drill.
Weed control will be one of the biggest problems, so if possible cover the paths between beds or drills with old carpet or shade cloth covered with beach sand, shell or gravel.
In areas of high wind, plant a wind break around 3 sides with local plants. Use a combination of small trees and shrubs. This will reduce the drying affect of the wind and form a micro-climate around the vegetable garden.
Gardens may need to be fenced to keep out dogs and unwanted guests. If the garden is fenced this can be used to grow climbers such as passionfruit, Bush Banana, Choko, Petrea, Pyrostegia or Jasmine.
