I purchase 3x15gal last year
Two from Lowe’s (via Laverne nursery) 1x Mexicola, 1x Bacon
And one from menlo grower Pinkerton
Two of them , which was planted in front yard doing great , see attached pics
That’s why I was willing to try 2 more 15 gal
Did follow some general guidelines, like don’t pull the tree from pot , cut the pot away , plus I mounted up , meaning only 1/3 of the plant was in ground and rest I put more compost and layer of mulch around
One thing that I noticed that trees from La-Verne was in much better soil, but the tree from menlo growers are in like crush rocks and sand , much heavier and not easy to handle
