Johnny's offers generative tomato rootstock — the type that directs more energy into fruit production — and vegetative tomato rootstock — the type that directs more energy into growing leaves and stems. We recommend choosing DRO141TX rootstock for general applications, especially when a longer production cycle is desired. Estamino is a better match for our French Heritage varieties, which balance well with this more generative rootstock. All of our rootstocks are selected to deliver the important benefits of tomato grafting: improved production and crop health; reduced or eliminated pesticide use; and lengthened harvest duration.
