I'm no greenthumb, I'm the opposite. But we have a large garden awaiting seed. And tomatoes are sooooo good when they are grown in your own soil. So, let mother nature do her thing. I'll try to keep the weeds out and water when it gets hot.
$36 (no. 85)
As for greenery indoors, maybe these terrariums from Etsy > MadeByMavis will do the trick!
