Q.Can I Transplant A Large Hydrangea?
I must move my hydrangea plant as it was sold to me as a small (dwarf?) hydrangea but has grown to be way too big for the area I planted it in. It is now about 6 feet tall and 4 feet wide. It is about 4 years old. It is currently starting to bloom (still small blooms). Do Hydrangea roots spread out under the soil or do they have a long root? If it has a long root, approx. how deep do they grow? Note: It must be moved within the next few days, so unfortunately I cannot wait till it is not blooming. Do you think it will survive? Note: I don’t know what kind of hydrangea it is, but I do know that it is NOT an “Annabelle Hydrangea”.

It would be best to wait till fall and when it isn't blooming. Since it needed to be moved within a few days, just make sure to get most of the rootball and have the new location dug and waiting. Make sure it is well watered till it gets reestablished.
The roots are composed of underground rhizomes that elongate and spread out as the plant grows. Typically the root zone is as far out as the canopy.
