## Questions & Answers

**Q: Is this microlife acidifier also a fertilizer? Do i need to apply this acidifier together with other fertilizer at same time?**
A: This is an organic fertilizer that has the added benefit of lowering the PH of alkaline soils.  You do not need to include a fertilizer with this product.

**Q: Would this be safe for Blue Rug Junipers?**
A: They are acid loving plants, so yes, this would work.  I use it on my azaleas and gardenias and they love it.  Also, much better for environment than synthetic.

**Q: Is this a good fertilizer for strawberries and raspberries?**
A: No, strawberries like a balanced fertilizer I.e 10-10-10.

**Q: How much (in cups) should I apply around a small magnolia tree? Medium size drift rose & a gardenia?**
A: For the small magnolia tree, I would estimate about 10 cups should be spread around the root zone (from the trunk to the ends of the canopy). For the drift roses and gardenias, I would use about 1/2 to 1 cup per plant spread around their root zones. This product is safe to use heavier if you prefer.
