Niiiice! I love these! That trunk is a WONDERFUL starting point.. nice find!
My forsythia did not grow too well this season, but that is because it is one of several trees situated on a bench which was COOKING my trees from underneath! (I don’t really want to talk about it

My Forsythia gets root-work in late-winter/early spring... actually BEFORE bloom.
It’s important to point out, because it points to the tolerance of these beasts, that the Forsythia was the only survivor of the “cook yo’ roots from underneath” table.
