We are in a severe drought so everything is struggling. Would we be
wise to pinch the flower buds and give the plant an opportunity to use
its energy to get established?


If you've got the patience, go for it. Try to get the buds as young
as possible. Yes, it will help conserve the plant's resources.

Don't forget to weed, also... most weeds transpire horribly. Mulch, even
dust mulch, also helps. And remember clematis likes shaded roots.
