Getting the best grower returns at harvest
With high fruit sets and good growing conditions in 2023, maximize grower income by focusing on harvest timing and field sizing. The keys to a timely harvest are 1) get the largest, high-quality fruit to the dryer and 2) field sort to keep small, low value fruit out of the bins. Continue reading
Twelve ways to ruin a prune orchard.
Good production of large fruit and sustained tree health are critical to maintaining profitable production. The following points highlight problems contributing to orchard decline. Continue reading
Weather after 30 days after bloom helps plan thinning and harvest.
Bloom date and cropload per tree still have the largest influence on harvest date and fruit size potential, but knowing GDH30 accumulation can be used to fine tune harvest and thinning planning. However, given cooler weather in the 30 days following 50% full bloom, knowing growing degree hours can better inform thinning planning. Continue reading
The most important task of the year.
There is no more important activity in prune growing than checking the crop load in late April (or early May this year?). Knowing the crop load (fruit/tree) in an orchard is the most critical piece of data needed to decide if shaker thinning is needed. Continue reading
Bloom weather and prune fruit set: what we know so far
Crop failure in years with extreme bloom weather (cool or hot) challenges successful prune growing in California. A new bloom weather model is a good starting point to predicting crop potential and, eventually, managing risk of crop failure. Continue reading

After the Rain: Maintaining Nut Quality
Sacramento Valley received approximately 2″ of rain during the last storm, leaving behind many wet almonds and challenging growers with reduced nut quality and decreased returns. Read ahead for best management practices for your situation. Continue reading
Is it time for a closer look at alternative nutrient sources?
With continued tight nut markets and high input costs, it’s worth considering all nutrient input options in an effort to lower costs and maintain production. Sustainable nutrient management includes assessment of irrigation nitrate, adding compost manure amendments or almond shells, and using nitrogen-fixing cover crops. Continue reading
Checking Cropload and Shaker Thinning Prunes
When needed, shaker thinning can improve a grower’s bottom line this year and next year. Careful, timely thinning increases A & B size fruit production, limits small, lower value prunes in the bin at harvest and improves return bloom next year. Continue reading
