## Questions & Answers

**Q: Can i use this when planting hydrangeas?**
A: Yes, it works very well with all the plants that I have planted, been using it for over 10 years, if you are planting  hydrangeas I would recommend  going on utube and watching Garden Answer it's  a great source for information

**Q: Does this kill roses? 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!
