fyzygy Posted February 14, 2022 Share Posted February 14, 2022 Recently I discarded some expired Vitamin B tablets -- into my compost bin. No problems there, I don't think, only now I wish I'd given them to my plants directly. While researching this topic, came across the following article, "Proven and potential involvement of vitamins in interactions of plants with plant growth-promoting bacteria—an overview" (2014). https://booksc.org/book/23177070/b1252a. It's ... a start. Quote Link to comment Share on other sites More sharing options...
