Grafting vegetable plants like tomatoes onto disease resistant rootstock is becoming increasingly popular, especially in high tunnels. Graft your favorite varieties' scions onto disease tolerant rootstock to get the flavor you love plus disease protection. Grafting improves plant growth, yield, hardiness, and disease resistance.

Grafting Tips: Expose plants to full sun and water stress a few days before grafting to keep the plants short and increase their stress tolerance. Water the plants the day of grafting to revive them from wilt before you begin. For best results, graft your tomato plants out of the wind and bright sun, and early or late in the day.

Cut both the stems on the plants (called a scion) and rootstock at the same angle. Move quickly, as the plants will wilt immediately. Line up the cut surfaces together before clipping in place. The more they are aligned, the better they will perform.

Untreated or Organic varieties are marked with or .
