m0useanswered grow question 16d ago the other plants will also take up some of the nutrients but if your providing enough they will be fine.
Clover is good as it offers groundcover and when it breaks down it releases N to the plants in a form they can handel, its does this by fixeing it from atmosphere N (n2) that most plants can not work with. its a big bonus of clover. Chives from the family of allium are also ok. but they don't offer any benifits that I know of. Does not mean their are none, I just don't see any especially for an infoor grow. I think deer don't like them???
companion planting normally has a pro to offset a con, eg, clover for extra N, marigolds for pest deterrent, dill for bringing in predator insects. their are tons of them these are just a few I know of... Old wifes tales say growing basil next to tomatoes improves the flavors of both plants. IDK if its true, I've done it before and they still tasted great no more or less but I grow in container and not the earth. I would love the patch of land to fuck around with. lesion is not everything is true so look it up with a criticle mindset and try and find the proof, know its not 100% even if it is true as u can still get pests with marigolds they just help a bit vs none at all.
In short you could use white clover as its low growing and when you trim it back its getting to stay small. Note it does not add much till after its tilled under and dies other then a nice ground cover to prevent evaporation. buy you can also mimic this with some woodchips.
