Q: What kind of hormone do you use to get a seedless tomato?

A: You were intrigued by my recent article about seedless fruit weren’t you?! Certain plants can be sprayed with hormones during flowering to induce the flower to set fruit without being naturally pollinated. Tomato gardeners in cooler parts of the country commonly perform this hormonal activation. Bonide Tomato Blossom Set Spray contains cytokynin and will produce the effect you want.
