A food forest can be one of the best habitats for insects, whether you know it or not. You may grow ornamental plants, flowers, fruits, vegetables, or a little bit of everything. All kinds of bugs will be attracted to the plant life that you have to offer.
There are hundreds of thousands of different insect species in the world. Most of them are harmless to your plants, while others may be destructive. However, many insect species benefit your garden by performing essential services that contribute to a healthy, balanced ecosystem.
How Can Insects Be Beneficial?
There are three main categories of insects that benefit food forests:
Spread pollen which helps fertilize flowers and fruits in your garden.
Eat other insects that feed on your plants.
Attack insects that are destructive to plants, controlling their population.
These beneficial insects work together to provide essential eco-management services in your garden or food forest. The garden would be overrun with pests that may devour your precious edibles or ornamentals without them.
Beneficial insects are the most environmentally friendly pest management system. Since their presence means that you don’t need to rely on chemical pesticides, you can grow organically and eat safe, high-quality produce. Not only do do pesticides exterminate the good insects and the bad, but they can also cause toxic runoff that kills fish and other animals further down the food chain.
