Q.maiden hair fern
I have about 10 ferns in my backyard, and they have lots of dead
leaves on the bottom of the plant and also in the plant. Can I
just clip them all down for the fall so when the fronds come up
in the spring, it will look nice and clean? Or will it harm
the plant?

Make sure to trim off the dead leaves, and keep this plant moist. Not wet, or dry, but in between. These leaves will regrow. Here is an article for more information on their care: https://www.gardeningknowhow.com/ornamental/foliage/maidenhair-fern/maidenhair-fern-care.htm
