Q.Could I prune a Bush Daisy which has gotten sprawled out and leggy?
I am caring for family members yard while they are gone for the summer. Other than pruning off the dead flowers, I think these plants could use cutting back. Much of the lower plant lies flat along the ground…with a large woody stem…then leaves and lots of blooms on the end.
But! Will this destroy the plant?
I don’t want to do that.

Deadheading and cutting back no more than 1/3 of the plant can help it to regenerate. Restorative pruning should be done in Spring, but doing so in Autumn won't hurt.

Yes, you can cut back the bush daisy. There is still plenty of warm weather ahead so you won't be chancing a freeze damaging the plant. Here is more info about the bush daisy:
