Grow resistant varieties of the plants you do decide to grow. The third step in your natural garden is to avoid mono-culture. It doesn t exist in nature, so it shouldn t exist in your garden if you wish your plants to be healthy. Mix different plants together within the garden, your garden will look better for it too. Right, the bit you have all been waiting for comes next.
Natural controls don t come any simpler than water.
Hose them off. If some manage to climb back up, then try milk, it clogs the pores of aphids and they suffocate. If you are still unsatisfied, then try paraffin, washing-up liquids and detergent sprays. For the unconvinced, try the ultimate weapons of natural control, namely, Derris or Pyrethrum, avoiding ponds and any watercourses, it is poisonous to fish. Slugs and snails are the bane of many gardeners and control is often necessary.
