I do stake my plants as with time they get a bit leggy, however, I have also followed some (excellent) advise from the list about cutting back in the fall to produce a bushier plant that has worked just fine! The only one haven't done this to are the serranos which now form a sort of pepper tree - relatively naked stem about 4 feet tall with a burst of branches at the top. They look sort of neat - like a rose tree only better - so I leave these be and support them with those slender green bamboo stakes you can buy at garden shops. I use strips of old nylon pantyhose to tie them - they can be cut wide enough so as not to damage the tender branches and its another way to recycle! Peace, love and peppers Lorraine
