I've planted 50+ seedling apple trees that were only around 12-18" tall and they did fine, but they just grew much slower. I think the weed competition is harder on the smaller trees, so it takes them several more years to fruit.I have always bought the standard large size 4'-6' tree from Whitetail crabs , I see Terry even has some Premium 6'+ trees this year.
For 2025 I ordered four of my usual 4'-6' trees , and three 2'-3' foot to try. While I'd rather have his larger trees, this year Finances are a little tight , so I got the smaller Redfield, Golden Hornet and a Death wish to save a buck or two. Has anyone had good look planting Whitetail Crabs smaller 2'-3' trees ?.
The last couple years I have purchased seedling dolgo trees from Yellow River Nursery in Wisconsin and they are great trees. The price per tree is under $5 when purchasing 20 if my memory is correct. I use those for my grafting rootstock and pot them for a year before transplanting. I also put some of those seeling trees in pots without planting since I like dolgo seedlings. Some of those dolgo seedlings are now 6' tall after keeping them well watered and fertilized in pots for this growing season.
