First of all, blossom end rot, is rarely caused by lack of calcium, but usually inconsistent watering. In fact, it almost sounds like all of your issues are from too much water. Peppers require less water then you think. Wilting is caused just as much or more from overwatering as underwatering. Don't water until the container feels light. Limping can also be caused by the cold, and usually will perk back up after several hours in warmth. Don't prune wilted leaves until you confirm that they will not come back.

It almost sounds like you are overcompensating (overloving) your plants. Let them dry out more. Let them recover more. Peppers are more resilient then you think. Quite often leaving them alone is the best thing you can do. Relax....

Capoman,

The previous wilting was definitely lack of water, which is why that was my initial thought and why I checked the soil moisture first.

Everything I've ever read about BER says it's a calcium deficiency. Whether a true lack of calcium in the soil, or just the inability to utilize what is present.

Yeah, but its fairly rare to have an actual calcium deficiency in the soil itself, so adding more won't help. Its usually root damage, often caused by overwatering.

Too much water causes the roots to drown, and the plant above is then unable to get enough water and nutrients up through their damaged roots to sustain itself properly.

Its actually one of the very few times foliar sprays might actually be beneficial.

Well, whatever the cause, they are indeed all dead.

This promises to be a very boring season now.

Do you have any peppers left?

That stinks!! Are you sure they won't bounce back? I was thinking that maybe pruning back tops and bottoms and repotting might save them. What a bummer!!

mbellot: If they are indeed dead, at least hit the local nursery and pick up some starter plants. It is going to be a long summer without a few peppers to fuss over. If you lived near me, I would happily donate a few of mine.

Cross country nursuries are still selling plants.

Wow, that sucks. I feel for you.

Yes, order/pick up some starts ASAP, my 8th vertebrate is forecasting a great 2012 season ;-)

Thanks to the suggestion by romy6 my pepper season is back on, even if it's been re-directed.

My shipment from Cross Country Nurseries arrived today, after splitting it up with my co-workers I'll be taking home four 7 Pot and two Bhut plants.

My overwintered Bhuts are hanging in (but not bursting with vitality) and one TSBT appears to have survived without incident. A second TSBT also survived but appears to be in deep distress. The leaves have been limp and falling off for several days, but since I moved it to a full shade area it appears like it might be starting to put out some new growth.

I also started a couple more seeds, although I'm not sure why since the growing season will be over before they're mature enough to flower...
