Man, that's a pampered dogwood! I haven't added anything to the hole before so I can't comment on those. But I wonder about the one in the back, if it's also a pink dogwood? I had a pink dogwood one time that just wanted to look flat. Meaning, it didn't want to grow upwards, just grow outwards. Almost like a creeping shrub on a stick. We ended up moving so who knows that happened to it. (That was around the time where dogwoods were dying from a virus and I had to liberally spray Immunox over the entire tree to keep the leaves on the branches. The symptom was leaves drying up and falling off, FYI).
