Get Ready for Thinning Season

Tory Schmidt, Tree Fruit Research Commission, Written March 10, 2016, updated April 1, 2018.

Spring is here and it is time to get ready for thinning season. While all aspects of orchard management are important, there may be no decision made by growers more critical to their economic bottom lines than how to thin their crop. Choices you make regarding your crop load management will fundamentally determine the primary drivers of your profitability: fruit size, fruit quality, total yield, and return bloom, not to mention how much time and money you will spend to hand thin, harvest, and prune your trees.

One of our best cooperators has a rather satirical, but sage perspective on the impact of these decisions: “Don’t worry if you mess up your thinning this year – you’ll have 23 months to figure out how to get it right the next time around.”
