They really do look either over watered or under watered.

If it's any consolation, I'm have a bad time with my peppers this year too (never had problems like this in the past). I think our lack of sun in April with so much rain and the last two months being the exact opposite has really taken a toll on a lot of plants - particularly tomatoes & peppers.

One other thought, it looks like your deck is a dark color. With the heat that we've been having, it can actually cook your plants and the soil (the dark deck color absorbing the heat & sunlight). I've been watering my deck plants almost every day. The garden gets watered twice a week, but I have clay soil which holds some of the moisture.

When one of your pepper plants does it, don't be too fast to just pull it up.

Get a trowel and dig a trowel-wide hole near the roots, and about 6" down. Are you getting moist soil all the way down?

If it's dry at all, that could be the problem. Some soils just don't absorb water as well as the owners think, or they're just watering the top and not enough water is getting down to the roots.

If the soil is moist enough, they may be infected with Fusarium or Verticillium wilt. (see link below from Ohio State U.)

My pepper plants are doing the same!!!!

It looks like over watering to me....

General rule of thumb is to only water when the leaves show the first sign of wilting... water for like 20 minutes and if after an hour they are still wilted then water another 20 minutes... Check again in an hour...

It ends up being that I only need to water about once a week, and only for about 20 minutes.

I have 34 varieties of hot peppers growing, and started them back around october :D.

There is a specific forum here on GW where the people specialize in peppers... You might think about asking there as well... Though you've already gotten some good advice from some of the previous posters.

Yup, that definitely looks like a watering issue. Peppers are pretty susceptible to overwatering, and the confusing part is that the symptoms of overwatering are the same as they are for underwatering.

Always let your peppers dry out and start to wilt a little before watering, then give them a good soak and go back to waiting for them to wilt again.

At first glance it most certainly does look like a watering issue, but then why does the plant immediately next to it appear so healthy?

Mich I interplant Moss Rose with my peppers. The Moss Rose will wilt before the peppers when drying out. Kinda like an Organic early warning system. Your Peppers look over watered to me to. Mine are in a rock garden. That rock wall should help the peppers for tempature control

I grow Jalapeno, Chile Grande, Cubanelle, Hungarian Yellow Wax, New Mex Sunrise, Colossal, California Wonder, Diamond, Golden California Wonder, Orange Sun, and Purple Beauty. In separate containers on a Deck. When my peppers start looking like the ones in the above photos it's because I haven't watered them enough. They all seem to require more water during periods of long, hot, days Regardless of variety. When watered and moved into the shade for a day they come right back. I'm not saying they can't show similar symptoms due to over watering, It's just that mine always wilt pretty much in unison With all varieties showing similar symptoms within hours of each other.

"General rule of thumb is to only water when the leaves show the first sign of wilting"

This is all you need to know!!!! ;)

I jtransplanted my cayenne pepper 2 days ago and I watered it in and its wilting and the soil is damp

Liam- Sounds like transplant shock. Was it a store-bought plant or did you start it yourself? How big was the plant? Was it hardened off prior to planting? And what are your temperatures like? If the soil is moist, don't water again until it dries out.

Just wondering, what zone are you in? Are your nightly temps still in the 40's?

I have several rows of peppers they were all doing great but every so often we get one or 2 that wilt and die quickly. I can't figure it out.

" I would give it a bit of epsom salts to ward of the blossom end rot"

I'm sorry but epsom salts is magnesium sulfate, not calcium, and while it could perhaps provide some benefit if the plant shows symptoms of magnesium deficiency it offers no benefits against blossom end rot.
