I think you shouldn't cut the fifth one. That's not too much really. On one of mine I grow six of them and everything is okay. Hope your tomatoes will be great.

I really like planting Mara des Bois, it's the best I have really. It's big and comfortable to pick. I don't know is it early or middle one, I think something between.

I use a glass containers. The only reason I've bought it was sale. I like glass things really, they are renewable and that's for environment. I use them in fridge and microwave. Not sure about freezing really. There is lots of them different sizes, just look through.

You can plant tomatoes. I've done it and everything is great now. It's also possible to plant cabbage, onion and garlic, bell pepper or beans. Think what would be the most comfortable for you.
