I found 2 cute wooden raised planters in my garage and was hoping to make my first mini garden in them! I would love to have a vegetable and herb garden but I'm not sure if it's possible with the sizing and I can't find a relevant answer anywhere so here goes: the dimensions are in inches 33(L) x 6(W) x 7(H) and a bigger one 61(L) x 6.2(W) x 7(H) inches. I know it's not very wide or deep but I was hoping to make the smaller one an herb garden with basil, parsley, mint, chives, and dill and the bigger one use 3 tomato cages on Japanese cucumber, Early Girl tomato, and green zucchini and then no cages on scallion, jalapeño, and spinach (I read that using a cage can get you more room by growing vertically). Do you think planting these makes sense with the sizing of the planters or am I too hopeful? Also does using tomato cages for cucumber, tomato, and zucchini make sense? Thank you in advance!

These size containers would be ok for the herbs, but not for the cukes, tomatoes and squash. The planter is not big enough, and not deep enough, especially for planting in a hot summer climate like yours. Even growing herbs in them, you may be watering several times a day. Tomatoes, cukes and squash will do best in at least 5 gallon containers or larger. Tomatoes have deep roots.both the tomatoes and cukes would need to be staked, and a small planter such as yours would not support the size stake needed.
It would be better to use the other container for drought resistant perennial or annual flowers.

agreed, much too small for squash, cuke, early girl, .. jalapeno is even very questionable and I would not try.
You might find some very tiny container variety tomato but even standard cherry tomatoes grow on a BIG plant which has BIG roots.
Most herbs, and leafy things like lettuce, spinach, grow well with a smaller area like this.
