In my humble opinion, it's enough to work through preparing soil, planting, weeding, watering, tending and harvesting. But there are things who incessantly chomp, damage, disfigure and sometimes kill plants or fruits.

In my gardens I'm talking about slugs, snails, beetles, powdery mildew, blight and so on.

More elaborate strategies are necessary with four-footed pests, such as elk, deer, cattle, rabbits and raccoons.
