University of California Cooperative Extension hosted a “Mid-Season Open House” focused on grafted watermelon on June 29, 2021. The program included demonstrations, training, and trial tours. On-site trials were testing multiple rootstock-scion combinations and various in-row spacings. UC reports that approximately 20% of the 2021 California watermelon acreage contains grafted planting stock, an increase of approximately 5-6 fold over recent years.
