I bought some of their hybrid oaks in 2017 for my dad when he turned 65. Most are still doing decent at our cabin. We each kept one at home. They're doing well, but each suffered and incident.
Mine lost about 6' from the central leader 2-3 years ago. Some kind of worm bored a hole in it. Last year I got probably 50 acorns from it that I currently have potted, waiting to sprout. It's roughly 12' tall, but the top is fairly bushy/round.
My dad hit his with an insecticide 2-3 years ago that nuked all the leaves. It was stunted for a year or so. His gets some acorns, but he has more squirrels than me, so I dont think he got any last year. His is probably 20' tall.
