In any garden there is potential for pest infestation. Organic pest control is particularly important since many pesticides can both be harmful to humans and kill beneficial insects as well as the ones that are harming your vegetables.
Most pesticides and chemicals aren't specific to certain pests, and in the process of ridding yourself of the creatures that are eating your lettuce, you are also killing the ones that actually help your garden to flourish. If you spray too much you also run the risk of causing some of the nastier and more adaptable pests to actually become immune to the treatment.
A key to organic pest control is to be able to identify the beneficial insects from the harmful ones so that you can take measures to prevent them from becoming such a problem in the first place.
The way in which you garden and how the garden is laid out can have an effect on pest populations just as significantly as the chemicals you may be tempted to spray.
Making certain that you clean up the debris at the end of a growing season ensures that certain pests cannot spend the colder months under its protection. Digging through the soil after clearing out plant remnants can also safeguard against harmful insects lasting through the winter to feed on your crops in the spring.
Rotation of crops is also an important way to control pests organically rather than with chemicals. Not only will implementing this practice protect you from plant diseases that can come with keeping crops in the same place every year, it also prevents pests from finding more permanent homes in a specific area of your garden. Even with a small vegetable garden, making a plan each season so that you know where to plant the next year can save a lot of time and work in the long run.
