Tomato plants get heavy, especially once they are mature and covered with fruit. Homemade concrete mesh cages are sturdy and large enough to keep the vine off the ground. Heavy duty stakes made from rebar secure the cages and keep the 5-foot-tall cages from falling over. Cut rebar into 30-inch pieces with a band saw and place each piece in a vice to bend them into an “L” shape. Use two stakes per cage to make sure they stay in place all season long.
