After a winter with sufficient chill hours, some of our earliest stone fruit varieties have started to wake up from their winter hibernation as they push the first blooms of the 2022 season. These first flowers bring anticipation for the upcoming season along with the anxiety of knowing that unfavorable weather conditions can now have deleterious effects on the 2022 crop. Blossoms become commonplace around the valley as hundreds of different stone fruit varieties will be in different stages of bloom in late February and early March.
We are in the process of grafting trees in some of our stone fruit orchards. Grafting is a process in which scion wood (a piece of wood from the desired varietal) is bonded to existing rootstock. This allows the new variety to reach harvest more quickly than planting entirely new trees. Different root stocks are beneficial for different reasons, such as drought resistance, increased vigor, or successful growth in a particular soil type.
We’re planting new trees on the blocks of land we’ve spent the last few months preparing for this very thing. Selecting new varieties is a process which requires a lot of research to ensure that only the best tasting varieties make it to our farms, but we also take other factors, such as harvest timing, into consideration to ensure a consistent flow of delicious fruit is available throughout the harvest season.
Unlike peaches and nectarines, most of our plum varieties are not self-fertile and require pollination from another variety to set a crop. Many blocks of plums are comprised of two or more varieties for cross-pollination. Every year we place beehives in our plum orchards to promote the cross-pollination process. Often, we include “bouquets” of a third plum variety in bins near the orchard as a supplemental pollen source.
