Input on my companion planted garden for next year.

This year im wanting to incorporate more companion planting methods into my garden. I was hopping to get some input on this years plan. The potatoes and sweet potatoes will be grown in burlap sacks.

If you are growing organically, which I assume, any of this guides would be good for your purposes:

Good luck!

Looks like a great plan to me. You may want to add some Borage near your tomatoes. I have had no tomato horn worms since I started using Borage. I was amazed.

I grew my potatoes in burlap sacks this year. A fair amount of the sacks rotted and fell apart. Those that didn't certainly won't be reusable next year. I was not impressed.
