greeneyes:".. if you have for example tomatoes next to basil or onions, the tomato pests will not like the basil or onions.
If you have tomatoes next to tomatoes, the pest will attack one and spread to the next tomato.
So it’s kinda like a mini quarantine to help your plants.

For future refenrence and further inquiry , I believe that it is called "Companion planting", frequently used in organic gardening .

Yes, it is companion planting, which has been mentioned before.

However companion planting in the garden goes beyond what I mentioned to consideration of depth of roots, as well as nutrients.

That doesn’t really apply to Marcella’s plants that she has in containers which is why I just mentioned the pieces of companion planting that might be relevant to her particular situation regarding whether to move them in their containers together or not.
