I live in northern New Jersey and wanted to know if it's possible to grow an avocado tree. Avocados are my FAVORITE and it would be so amazing if I could grow my own!

Welcome to NGA, @dylantmejias27 !

I'm sure you could grow an avocado plant indoors, but I don't know that it would ever bear fruit. I've never had any luck growing one for any length of time. Maybe if you have enough patience to move it out in the summer and indoors in the winter, and have room for a pretty large plant...

well, you could... but I've never had any luck getting a higher zoned plant to survive indoors for me. That might be because I neglect them and they dry out (probably), but also I'm sure the dark winters here and all the time inside don't help. If you're willing to really work at it, get a grow light maybe, I'm sure you could do it. I couldn't.

There are avocados that are hardy down to about 15 degrees. That said, those temps are for mature trees.

I grew a Mexicola Grande improved in California Zone 8 but for the first 5 or 6 years of its life, the trunk was wrapped in Christmas tree lights (the old fashioned ones that give off heat) and the top had a shop 'trouble' light hanging in it.

If your winter temps never drop below 15 or 20 degrees, you could. Also, the earliest avocado trees produce fruit is at 3 or 4 years old. Mine didn't set fruit until it was almost 9 years old.
