Hello to all...I use a product called Vitamin B1 by Liqunox, (0-2-0) for every transplant or change of soil, indoor or outdoor plants. I have had incredible luck with planting and transplanting. It doesn't take much (read the label). I worked as a gardener for 2 decades and now retired I continue in my own garden. It has never failed to help in planting, separating plants grown too many to a cell, planting trees, shrubs, groundcovers, annuals, perennials...you name it. Indoors too. I buy the biggest bottle they sell. It's wonderful and the plants love it. Happy gardening to you all. 😎
