Oh - another thing
If you happen to be growing chillis in your greenhouse/patio/scout hut (and you should be!!) and you come across the advice to control vegetative growth by restricting the plants to smallish pots thus stressing the plant into producing many, many more fruits, ignore it. It's cobblers. At least, it is for jalapenos, so it should be true for others (I'll know that at the end of this season).
Use a smallish pot until the plant is about 6 to 8 inches high, then get it into a really big one (I use between 3 and 5 gallon size). Take off the first fruits for use as soon as they reach a reasonable size and feed that plant!! It will grow into a 3-foot high bush. I kid you not! Anyone would describe these plants as bushes. When you get fed up of eating green chillis, leave the plant to its own devices (apart from watering, feeding, etc) and you'll soon have a long succession of red chillis which you can eat, give away, or freeze (as is - no treatment necessary).
I still have about 5 lbs of the things in my freezer from last year, and the new plants for this season are doing well.
I did try overwintering them last year. Epic fail!
