It’s (way) too late in the season to plant anything.
But if you’re contemplating a landscaping project (patio, steps, grading, etc.), you’ve got another month or so before the ground freezes and the window for doing work closes.
Two other benefits to doing the work now (vs. next Spring): landscapers are looking for work; and (therefore) their prices are better.
I know two people doing projects right now, for exactly those reasons.
