Hello and what a nice little avacado plant you have. I'm brand new and just learning my way around. However, I have owned two avocado trees grown from seeds
. The big difference is that I lived in Florida for many years. When my seedling
was about 3-4 feet tall I planted it outside. You will certainly need to see if your climate will permit this. Our tree produced fruit in five years, I think. It was wonderful fruit.
I don't believe there will be any branches until the plant is a bit older. I'm sorry I don't really recall how long that took. Best of luck and good work!
