This is my first year container gardening so you can pretty much take everything I say and do the opposite! If you have a place to hang something, try strawberries in hanging baskets. You can put 3-4 plants in one regular basket and they're beautiful with the green leaves, white and pink flowers, and red fruit.

As far as the other stuff, all I can say is whatever size container you think is good, go a little bigger. Pretty much everything I've done this year, I wished I had used a little bigger container.

Also, self-watering containers are worth it! I'm not really sure if I'm over-watering or under-watering but the plants I have in self-watering containers consistently look much better than the others. I haven't decided whether to do containers again next year or some raised beds but if I do containers, I plan to make some self-watering boxes this winter.

Hopefully somebody here will have better advice for you. Good luck!
