I plan on planting quite a few peppers this year and lack space to separate them. Also I want to plant them close together so when fall comes I can build a mini green house and put plastic over them. I plan on doing this by planting them inbetween the hogpanels I am going to grow tomatoes and green beans on. Anyway my question is, what kinds can I grow close to each other? I think habs will cross with each other but not with tabascos, etc. I read somewhere what will cross and what will not. I also read that when you want seeds and they are close together to tie some cloth over one branch that is flowering and leave it until the fruit sets on, then tie a string on it so you will know which branch to get seeds from. Am I on the right track here? If that is the way you do it then it shouldn't matter how close together I plant them, right?
