transplanting old azaleas
new york south region
a few years ago i moved a bunch of small azaleas to a different area of the house. i clustered them in hopes of creating a tight geometric shape. i think the area i chose for transplant gets way too much hot afternoon sun. i want to move them again to a more shaded location. is it advisable to cut them back significantly prior to transplant? these were my fathers and are about 15 years old so i would like to save them for sentimental reasons.
any advice on this would be appreciated.
