Forgot to ask what the best pruning method is ....?

Thanks

Per the link below...

Paniculatas (PG/Limelight types) can be pruned in the fall, winter, or spring. However, it is not necessary to prune them every year. It is suggested that one trim out crossing branches and those that do not contribute to an attractive form whenever necessary.

Paniculata hydrangeas are the only hydrangeas that can be pruned into a tree-form. If one is attempting to grow a paniculata as a tree, the developing trunk and main top branches should not be removed. If a panicultata that is trained into a tree-form is cut or broken off close to the ground, it will grow back as a shrub unless the training and pruning is started again from the new shoots.

Thanks again, and any other advice is most appreciated!
Nothing to add but my Limelight grown as a shrub is big, beautiful, and pretty carefree. I just wish it wasn't located in the middle of a flower bed, since it has gotten so large and there are so many other 'better' locations for it.
