Have a 7-8 ft bloodgood and every year, it's has diebacks so the tree doesn't seem to be getting larger. It could be due to my watering method. Last year, the tree iddn't leaf out until May. This year, after some deep watering, the tree leafed out mid April. I'm in Zone 10B. So it may be too hot for the tree? I'm trying to find a tree to plant next to the maple to offer some dapple shade. But in the meantime, I've discovered Protekt Silca that is suppose to help the tree against the harsh Sun and Wind. So, anyone else having dieback issues on their maple?
