I've never seen deer eat rhubarb here, surprisingly. They eat the hostas down to the ground, but never touch the rhubarb. Rhubarb is the one thing nothing here will touch so I grow it outside the garden fence. I googled it & this is what I came up with: Slugs, snails, leaf beetles, beetles, and deer are the culprits you should look out for. These pests are the most commonly known for eating rhubarb leaves.
I'm sure it's different for you as you're much hotter, but I'm able to grow lettuce most of the summer by growing it under shade cloth. It grows well enough here for the most part except in August. I grow enough to just cut it down instead of picking the outside leaves, it keeps it from bolting.
Debating on starting some asian cukes inside. I said I wasn't going to do any starts, but I think I will. Maybe some squash too. It's just so darn cold here at night still. But my beans look good under the hot house out there.
Went to the Depot yesterday, got a new spigot & some hose to run to the farthest end of the garden. & a new 5 gal bucket for a bigger chicken waterer. Looks like back surgery is inevitable & I won't be able to put it off till after the harvest so I'm trying to make everything as easy for DH as I can.
Haven't slept in days because of the pain so I'm just sitting on the heating pad today. But I need to get my starts outside for a couple hours & get a cattle panel cut up for supports for the peppers.
