Conventional Tomato Cages
Conventional Tomato cages come in different styles, most are made of wire, and are cone shaped, some are round. Some cages sit on top of the ground and are anchored to the ground with a stake. Whatever variety of cage you choose, you will need to be certain that it is tall enough and strong enough. It needs to be at least 5-6 feet tall and at least 18 inches in diameter. Additionally, the wire should be strong enough to support 8-10 pounds without bending or collapsing. The cage should be installed when the tomato plant is about a foot tall. When installing the cage, make sure that it is securely anchored to the ground so that it can't blow over in high winds.
