Did I screw up when planting?
I planted out thirty or so hydrangeas that have been in pots for many years. None seemed root bound which seems kind of shocking since some of them have been potted at leat 15 years. The problem I ran into is a few of them (about a third )came out of the pot with only the top half of the dirt attached. I didn,t see any roots in the dirt left in the pot but give that they were potted so long how I don,t see how they could not have had roots all the way to the bottom. They have not leafed out yet and I,m in the pacific northwest so they are really wet all the time I don,t know if they helped them not develop deep roots or if I just broke off most of the roots and just couldn,t see them. I put some aged horse manure in the holes should I be doing anything else to stimulate root growth or did I just kill them?
