For squirrels refer to Bucket of Death- check link. Otherwise, expect to need a full chicken wire enclosure, although netting will work if they are not too hungry- I like the woven kind- monofilamint gets tangled without a frame and is more easily torn through. I've noticed that they don't like climbing plastic fencing, so it's possible if you devise a support system for it without posts they can climb (place on inside of closure, bury the netting at the base and nail arms out from the post to hold the netting up, for example) you wont need a full enclosure. I noticed some panicked squirrels inside a plastic deer fenced enclosure and they wouldn't or couldn't go up the plastic and scurried until they found posts. Actually, come to think of it, 4' of fencing with a couple charged wires can stop squirrels (and most other critters) as well, if it's rigged up right so the squirrel gets zapped while hind legs are touching ground or the metal fencing closely behind the hot wires. Best to use a constant charger instead of a pulsing one for that. They aren't available as solar powered units last I checked. Here is a link that might be useful: bucket of death

Too much heat and not enough water would probably be showing browning after wilting of rhododendron growth. Without a picture, I would guess insect. If you lived in the east, rhododendron midge would be a possibility, aphid and white fly can also cause distorted new growth. Have you checked undersides for any visible signs of insect?

It would be nice to see a picture of the plant just to make sure what you're seeing isn't just leaf roll or leaf curl. I am continuing to assume there is true distortion (stems bending down and curling and the like). It's been a couple of days now. If they're in the same condition then I would further believe it is not a disease. Again, I don't know of any bacterial or fungal diseases which will distort a plant and not have other leaf symptoms (lesions etc). It seems like you have other plants (not tomato) that aren't affected and are in the same basic area that are being watered with the same type of water (water conditioners with a high salt content can present problems to tomatoes and peppers). So, if it isn't environmental (weed killer*, salt in water etc) and it isn't a disease, and it isn't bugs, the only thing left is virus. TMV (tobacco mosiac virus) and to a lesser degree CMV (cucumber mosiac virus) are posible, but pretty unlikely. TMV just isn't around much and you'd probably have other plants with problems if CMV. So, if things are holding the same and/or improving and there is new growth that is doing fine it could just be one of those temporary things they grow out of. I've seen that happen before. Good luck. Randy *Note: Keep in mind if the neighbor sprayed weed killer and there was a breeze it could have drifted.

It's true that herbicide is much more common. But that very stark transition from perfectly normal leaves to very distorted leaves is a distinguishing feature of CMV. Also, the lack of epinasty with the affected stalks still growing very straight makes me think it's more likely to be CMV. Is that a pepper plant at the very bottom left of the photo? At any rate, it's true that herbicide is also a possibility, as I have said before. But as I said, either way, those plants are better replaced. They're unlikely to outgrow the herbicide damage to the extent that they'll be productive, and they're never going to outgrow a virus.
