Q.Indoor planting
Hello, I am growing Zucchini cucumbers strawberries peppers carrots and peas indoors in suitable
containers. I know vegetables can be companions together if they are compatible with eachother, however, is it ok for me to companion my vegetables in the same pot. For example, I put zucchini and bell peppers in the same put to grow, is that ok? They are growing fom seeds and are now seedlings that were ready to be transplanted into a bigger pot. Right now I have zucchini and bell peppers together in one pot together and I have transplanted my peas seedlings into another pot, when my carrots grow more leaves I will transplant them together with the peas (the pot is large and deep enough for the carrots to grow). Is this ok?

Companion planting is not as easy to do with container gardening. I would suggest you keep your plants as individual plantings to provide enough growing room for the plants.
Your vining plants such as zucchini and peas will also need supports-taking up room in the container.
Carrots should be direct planted into your container. Transplanting would not likely be successful.
