Against my better judgement, I ordered a BRT. Looks like I am going to have to grow this little guy out for a few years before doing anything to it. I live in Ohio, so my question would be. What are my best option to grow it bigger? I’m thinking of putting it in a 10” planting pit and let it grow without messing with it for a few years. No greenhouse, but do have a south facing window for winters. Any suggestions? Thanks
