I posted this on the main forum, but got no replies--I too have been having problems with my peppers this year. The one plant has two very small (teeny) peppers that dont seem to be growing. The other plant has just started to blossom--we are having a drought here in central NJ, but they have been getting enough water.
What gives?

Peppers like not only lots of sunshine, but hot temperatures too. I don't know how hot your summers are, but if you don't hit into the high eighties or more, that could be factor.

Also, peppers are heavy feeders. They will perform far better with a liquid fertilizer applied every two weeks.

Finally, they need good drainage. Is your soil nice and crumbly? If not, try working some peat moss, rotted leaves, or aged manure (you can buy the bagged kind) into the soil. Two or three inches spread over the top of the bed and worked in will nearly always do a world of good.

I'm in NJ as well and my peppers have been just sitting there for a while not doing a whole bunch but now they seemed to come to life. My Anaheim has couple peppers on it and so does my Thai Dragon. I have 4 Valencia Bell peppers from which 2 got a lot bigger the last week or so and are now blooming. I was almost 100% sure my bell peppers were not going to make it at one point but they are making a come back now and are looking pretty healthy again. Epsom salt foliage spray I think helped with that is I sprayed that few times. They got nice dark green after that.

Just give them more time and hopefully they will pick up for you as well.

Interestingly, my hot peppers seem to be doing better than the sweet peppers. One of them, czeck black, already has a few peppers going, other hot peppers have flowers. My lipstick peppers are small, munched and just sitting there. We just had a week of hot temps and another to come this week. Prior to that we had a LOT of rain. I will try giving them some more compost and some epson salt and see if that does the trick. Thanks!
