When you have so many different kinds of chiliplantor in a small space (My chilihus is just on 5 square meters) so can seedlings actual cross with each other. If you take the seeds of its fruits, and then driving up plants so you can be pleasantly surprised when the plant bears fruits and not at all look like the kind you believed that you pushed up.
If you want to be sure that chili should not cross itself, we must isolate the chiliplantans flower before it turned out. This can be done in many different ways, some put a little glue on the flower so it can not open. I use a regular nylon stocking that I cut to and then Threading over flower. I then put a rubber band or tie a small piece of string around so it will be tight.
Isolate chili? How do you do?
