Mine are in 1.5 and 2.5 gallon pots. Roots were sticking out the bottom a month ago. Shouldn't they still bloom once the peppers are picked off the plant though?
In theory, yes. Although I've lately kept the pods on my plants until I'm ready to eat them, and my plants are currently blooming like mad. The cayenne now has only two pods, but tons of flowers. The jalapenos have at least 9 pods each, and are also blooming. (Note all 3 plants are first-year plants.) I'm in N.E. Ohio, and we've started to have cool days, but cool nights mostly (low 50's F.) Has warmed up again these last couple of days, but I wouldn't call it hot. (Keep in mind I'm originally from Texas, so my definition of hot isn't the same as most northerners'.)
But here's the thing. I had my pots in a particular area of my back porch so that they got morning and late afternoon sun, but missed a chunk in the middle of the day. That was fine at first, but then after the summer solstice as the shadows got longer, they got less and less sun. Started turning somewhat yellow and stopped producing buds. So I moved them so as to get more sunlight again, and they've gone back to a deeper green. I then managed to get a lovely visit from spider mites, and the leaves started drooping and getting weird pockets in them. Between the cooling off, cutting back all damaged leaves, and getting them more sunshine, they started producing buds again, and as I stated already, are full of blooms right now.
So questions for you - are your plants really getting enough sun each day? - have you seen any signs of bugs? - how old and tall are you plants? The 1.5 and 2.5 gallon pots do sound like they're too small but note the roots will eventually start growing out of a 5-gallon pot, too.
