How far down and spread does this hydrangea root go? Want to replace it with dwarf weeping flowering tree that likes a lot of sun. Zone 8b
Biggest hydrangea the in our backyard 5ft tall and only *one day* of 80 degree temps burn the leaves, as pictured, because the previous owner planted it in thee most scorching sunny spot in our north facing backyard.
It gets plenty of water because we know what a water hog it is. Doesn’t matter. What 6-7ft weeping dwarf flowering tree can replace it?
