Growing herbs and onions in metal tubs

Zone 29 Palms, CA | Anonymous added on June 3, 2019 | Answered

I am to plant herbs and various onions and peppers in metal wash tubs and buckets. Before planting seedlings and/or small plants I'll have about 6" of river rock in the bottom with Miracle Grow soil om top, about a foot or so. Question is, with drainage rocks will it still be necessary to cut or drill drainage holes in the buckets before filling?

Yes, you will want as much drainage as possible. It will be best to use an organic potting mix with amended compost, or other synthetic feed WITHOUT slow release nitrogen.
