HOW CAN PLANTS GET SICK?
Plants can be damaged by getting too much, or not enough, water and sunlight. The weather can damage them too. Humans can cut them down, mammals, insects and tiny worms called nematodes can eat them, or microbes can infect them. Microbes are tiny living things such as bacteria, viruses and fungi. They are found all around us and are too small to be seen by the naked eye.
