Kilayim

I would like to ask what kilayim laws should be kept in mind when it comes to sowing a pasture strictly for animal grazing purposes. For instance, would I be able to sow red clover and ryegrass in the same field for the purposes of cattle grazing (red clover has medicinal benefits for humans, but wouldn't be benefitting from that property, it would be solely for the cattle)?

You taught me that flowers and non-edible plants (and trees) can grow under a vine, but vegetables and edible herbs cannot.

What about a plant that I understood to be only ornamental, but I have discovered on the internet can also be used like spinach and other edible leaves?

 The plant in question is sweet potato vine. Its roots or tubers are not edible but the leaves can be used as food. Is it a problem even if we don’t eat them?

Our grapevine is in its second year of orlah. If we cannot let that plant grow under the vine, has it had a negative effect on the vine and future grapes already?

I am a kindergarten teacher. We have a vegetable garden where we grow seasonal vegetables and various herbs. Can we plant different vegetables in the same patch? For instance, cabbage, lettuce, broccoli, parsley? If so, what is the distance necessary between the different types of vegetables?

Is it permissible to throw vegetable scraps and seeds near a vegetable garden for the purpose of fertilizing the soil?

If I were to graft on peaches, would that be fine as it is the same species as nectarine, or it is as if I'm grafting onto the rootstock again, and would therefore be not permitted?

Shalom Rav, B"H I was zoche to move into a new home in E"Y with some fruit trees. I have a nectarine tree growing in my garden, and I am not sure what the rootstock is. Am I allowed to continue tending to it since it's safek kilayim? 

Can turmeric and ginger be planted in the same planter together? Or do I need to create a physical barrier?

Shalom Uvracha!

Attached are two pictures of flowerpots which were planted with spices (a few weeks ago).  The flowerpots are mounted on a stone fence.  I was told that the spices are at least 15cm apart (does it look it?). I don’t know which spice is which.  The gardener gave the following list (although I’m not sure that all of the list is in these 2 specific flowerpots):

לואיזה
מרווה
גרניום לימוני
בזיליקום
אורגנו
טימין

Can you tell from the pictures which is which? And is there a problem of kilayim (or something else)? Kilayim now or kilayim in the future when the leaves grow and overlap?  And what I should do to resolve the problem, if any?

I have two questions: 1) What are the three categories according to which you can classify different types of plants vis-à-vis kilayim? 2) According to which categories are different types of plants classified today in terms of kilayim?

I initially planted mint in my garden 50 cm away from my tomato plant. Later on, the mint spread towards the tomatoes. Is it necessary to cordon off the mint and uproot some of it?
