Before we get into a discussion about pests, let's explore some gardening
techniques that can help prevent or minimize pest problems. These
techniques are often called cultural controls.
- Grow resistant
or tolerant cultivars. We talked about this earlier in the course
in our discussion about choosing varieties.
- Practice good
sanitation. Remove crop residues after the harvest, prune away damaged
and diseased foliage, and keep garden and nearby areas weed-free.
- Space plants
properly. Adequate spacing improves air circulation, reducing the
spread of diseases.
- Rotate crops.
Don't grow related plants in the same spot more than once every
three years. (see sidebar)
- Grow a diversity
of plants. This reduces the chance that one pest will damage the
entire garden. And it encourages the presence of beneficial organisms.
- Avoid wetting
plant foliage when watering to minimize the spread of diseases.
Also, if possible, don’t work in the garden when foliage is
wet.
- Encourage natural
controls. Spiders, birds, ladybugs, and toads are all helpful with
controlling pests.
