I'm delighted! Lovely start!

What?! No chili peppers? That surprises me.

Consider at least 4 foot wide chicken wire, which is kind of expensive but much more sturdy. Leave a one foot "apron" flush on the ground on the outside of the plot. Put rocks on the apron. Digging animals go laterally as far as they can, then dig down, so they'd be trying to dig through chicken wire. If deer are a problem, use inexpensive 7 or 8 foot stakes, and string deer fencing, or that plastic you already have, up high so they don't jump over.

Looks really good! I'm so happy for you!
