I am so glad that I started trying to garden even while in my apartment, because I have learned so much. I have had lots of failures but they all taught me something! In fact right now I have two ginormous tomato plants inside my dining room area (they were on the balcony during the summer), growing tomatoes!
By the time I have a little land and a tiny house, I'll be MUCH better prepared than if I had gotten there with no practice.
And a few chickens is on the wish list. But can't practice with those in my apartment. ;)
