Backyard Orchard News
The milestone is significant, since the southern highbush blueberry cultivars grown in California originated in the Sunshine State. Southern highbush cultivars are well adapted to the California climate because they require fewer “chill hours” to produce fruit.
A leader in the development of the California industry, Jimenez has conducted blueberry observational trials – looking at yield and flavor characteristics – for more than a decade at the UC Kearney Agricultural Research and Extension Center in Parlier. In addition, the Kearney blueberry plantings have been the scene of ongoing studies on plant spacing, mulches and pruning, research that has helped farmers successfully establish the crop in the semi-arid San Joaquin Valley.
Jimenez will invite blueberry farmers and those considering entering the industry to Kearney this week to taste and compare 35 varieties of berries. Looking over the plots, Jimenez said it wouldn’t be difficult for a farmer to use information from the Kearney trials to select good-tasting berries that ripen sequentially for months, extending one farm's blueberry season from spring until mid-way through the summer.
“You could plant Snow Chaser, a very sweet, early variety, in hoop houses and start harvesting in the second or third week of April,” Jimenez said. “Next, Reveille could come into production. Southmoon is really late and then Centurion, a rabbit eye blueberry that’s small and sweet, would be ready in late July.”
On Wednesday, May 18, Jimenez will lead a tour to small and large commercial berry farms and packing facilities. Discussion topics include blackberry sunburn prevention, blackberry trellising systems, blueberry field design and layout, soil and water acidification, irrigation scheduling, harvest practices and blueberry packing and cooling.
A blueberry meeting on Thursday, May 19, features presentations on world production systems, blueberry nutrition, frost protection and blueberry market outlook. Following lunch, participants adjourn to visit the research plantings and industry exhibits.

put the rain gauge back up in my backyard today. Showers – OK, 30-90% chance of showers -- are predicted for the next three days. Spring rains can help bring about prune rust infections on prune leaves. Infested leaves will drop and defoliated trees produce small fruit.
If you haven’t already started looking for rust symptoms in your prunes, you should look after this series of cold storms roll through. Thursday is supposed to be clear and 79.
Details on rust scouting in prunes can be found at: http://ipm.ucdavis.edu/PMG/r606100611.html.
Basically, every week beginning May 1, look at 40 prune trees per block. Look for any rust spots. Spray (sulfur or labeled, Group 3 or 11 fungicide) once you see the first spot (see photos). Keep checking after you spray. If the number of trees with rust spots goes up, spray again. See the new UC ANR Fungicide Efficiacy and Timing publication at: http://ipm.ucdavis.edu/PDF/PMG/fungicideefficacytiming.pdf
Don’t let rust sneak up on you. It is easy to scout for and control as long as you know what you are looking for. Keep a healthy and profitable orchard with a strong canopy that can produce high quality prunes -- monitor prune rust and control when needed.
