Disney world does this! Lowes sells the 4 to 6" round PVC pipe with holes already drilled. Purchase an end cap, fill with rock, soil, and plant. I will often put these in the center of a very large pot to stabilize, and add amazing height and color to a container that has trailing plants (no end cap or rock needed if you are placing in a container)
Snipping off the “suckers” from a tomato bush will help the plant to focus its power on the rising fruits instead of the leafs, Growing better, healthier fruit. Clipping any branches off at the bottom of the tomato plant that is reaching the ground helps to ward off insects and mostly disease, such as blights and wilts.
