Lemon Boy is an yellow slicing tomato that is an easy to grow plant that should be staked or caged. It is an indeterminate plant, meaning it continues to grow and produce fruit until frost, with the harvest lasting several weeks.Keep plants evenly watered to prevent blossom end rot, an environmental condition caused by calcium deficiency. When plants get excessively dry followed by over watering they cannot uptake calcium properly. Regular watering can prevent this. Fruit size is 7 oz. each. Tolerant to Verticillium, Fusarium Wilt Race 1 and nematodes.
