I like using it on all of my plants, indoor or outside. On the outside I have used the big 6 on my roses, rose of sharon bush, rhododendrons (helped with new growth and many new flowers) and on my hedge after a early spring trim (cut off two feet, hallowed out center to help with dead wood and to spur on new growth.
