I am tentatively planning a tour to British Columbia the third or fourth week of July to visit orchards and the Summerland Research Station. I am hoping that we can evaluate Skeena and other late cherry varieties during our tour. If you are interested in participating in this tour please contact the Wasco County Extension office at 296-5494. We will begin a list of potential participants and apprise you of progress as more information becomes available. The following are notes that I took during Dr. Tim Righetti's presentation at the Orchard Managers meeting on April 13.
Boron increases ovule longevity, improves pollen tube growth and increases winter hardiness.
The element is mobile in the soil but is immobile in the plant. In other words, it does not move in the phloem. In order for it to reach the buds and fruit it must be in the phloem. It is easy to get it to the leaves, but more difficult to get it to the phloem. A fall application of boron, before the leaves fall, does the best job of getting the element into the phloem and buds.
