Can it be used on a hybrid rose?** A: I don’t think it will kill the roses. You are using this to get their roots established when you first plant them. After that, use rose-tone. **Q: Should i use this to transfer my lemon tree to a biggger pot? And can you use this on apple seeds?** A: You can use it when transferring your lemon tree because this product works to promote root growth and lessens transfer shock. This should work with the seeds as well. **Q: Would this be a good soil for transplanting spider plants?** A: Yes. I don't know where these other answers are coming from but it can be used for transplanting any plant inside and out. It can even be worked into the soil as a topper with great success. You can use it for seeds, transplants, and established plants. I have never had anything but success in using it in those ways. In fact I have used it for indoor spider plants myself! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by F***X on 27 November 2025* This product is excellent! it worked very well on all of the plants that I used it on!
