Checked my Hazelnut trees last night, I planted and tubed some, caged some and just planted some with no protection. The ones in the tubes are going crazy, they were about 3' when planted and now are close to 4'. I'm waiting to see if the others catch up after a couple years. I'm also curious about the unprotected ones, if the deer leave them alone or not, the guy I bought them from said he never protects them from the deer so I thought I'd try a few. The unprotected ones are planted on the edge of the woods not out in the open like these.
