Well, so far , like I said, out of 3 blackberry autos from fastbuds only 1made the grade. One is super sensitive to anything and doesn't seem to want to grow, one was a runt and the third is doing great. All same soil, lite, same environment. Must be genetics. Autos as a whole are unstable. I don't care what anyone else says. Nature don't work that way. It takes years and years to stabilize something that has NEVER happend naturally. Man made hybrid of different species. Every seed is not the same. Just my opinion. And opinions are like assholes, everyone has one, and they usually stink.
