Spiders are beneficial guys/gals for the most part. If you don't like the webs, just take a stick and destroy the web. Often the spider will move on to another place. With fall coming on fast now, some may not even build another web.

beneficial .... they are hunting the bugs you really don't want ... destroy the spiders.. and you may have bigger problems ...

please.. let them be .... they seem more apparent in fall .. misty mornings highlight the webs.. which disappear when they dry ...

you have planted a garden to revel in mother nature.. spiders are included in such ... let them be ...

they might be the webs of spider mites and you will want to eliminate those. those are more apt to thrive in dry conditions (such a drought) and can be controlled with regular misting of water to the foliage as it interferes with the breeding cycle. if you are seeing a network of fine webbing and no(easily) visible spiders, it could be spider mites.
if they are the webs of regular garden spiders, let them be as recommended by above posters.

Here is a link that might be useful: spider mite control

Mites make fine, close webs not likely to be noticed without looking very closely. Severe infestations may draw attention first by causing discoloration of affected plant parts, after which webbing may be discerned in places like the angles between leaf blades and leaf stalks.

Put a white piece of paper under a branch and tap it with your hand. Then run a finger along the surface of the paper. If you get red streaks, you have spider mites.

This is the time of year when spiderlings make their little webs all over the place. I've been noticing them all around my home, too. There's not a thing you should do about them, as very few will survive for very long. The ones that do should be a welcome addition to the landscape.
