A new grower bought an Asian pear orchard that was planted a few years ago north of Peoria, IL. Except for pollenizers, it’s all ‘Shinko’, and apparently its resistance to fireblight is very good – I saw only one or two infections in hundreds of trees.
They have planted trees at very high density (4 feet in-row by 12 feet between rows); the trees are at least 12 feet tall. Is anyone familiar high-density production of Asian pears? And if so, do you have any pruning recommendations? It’s obvious the density and prior pruning practices will not work together. The fact sheets and similar references that I’ve seen suggest much lower tree densities (218 to 242 trees per acre). Any general thoughts on managing the trees at high density … and what spacing would you recommend for the additional plantings they intend to make?
