## Questions & Answers

**Q: What is nutrient composition? Nitrogen, potassium, etc?**
A: Nitrogen, phosphate, potash, 16-4-4

**Q: I have a small Japanese Maple and 10 young tea olives that I want to use the spikes to fertilize. How many per tree would be enough trough spring and**
A: It depends on the diameter (i.e., trunk width at 1 ft from grade) of the trees.  If 1-2 inches, then plan on 2 spikes per tree.  Above 2 inches, its basically 1 spike per inch diameter.

**Q: We have a 25 year old (40ft) maple tree in tx that doesnt look healthy. Will this product work? How should we use it? Thank you**
A: Your maple needs iron like someone else posted. So no, this product is not enough because you need the IRON!

Try this product from Jobes: Ross® Green Again Iron Formula Root Feeder Refills

Make sure your trees are healthy and green all season long with Ross® Root Feeder Refills Green Again® with Iron. Chlorosis, a yellowing of the leaves with green veins, is caused by a lack of iron in your plant’s diet. Use refills in your Ross® Root Feeder to get the perfect balance of nutrients directly to plants’ roots - while watering. These refills are a special formula of fertilizer plus iron for plants suffering from yellow-leaf iron deficiency. Apply when first symptoms appear or to prevent deficiency if chlorosis has been a problem previously. Ross® pre-measured refills make for fast, easy and mess-free fertilizing.

**Q: is this Spike for Dogwood Trees?**
A: I do not know about dogwood trees.  I have used this spike on my Hickory tree, Ash tree, Maple tree and Spruce tree.  They have all done well. Grew larger with many leaves.  I am not a 'gardener' but person who uses fertilizer on my lawn, shrubs, flowers and trees.  Dogwood is a deciduous tree and I would think that these spikes would not harm it -- as I have used it with my deciduous trees.

    Received fast and what I ordered
  

*by F***D on Reviewed in the United States on 6 August 2024*

I have put these around several trees and bushes in my yard over the last five or six years. They seem to really help my trees and bushes as well as flowers grow better. I don’t necessarily use them as prescribed and will just break them up and throw them in flowerbeds or around the trees. I know I should put them out further on the trees at the drip line, but some of my trees were small and I would put them fairly close to the tree. I have one oak tree that I don’t know if it don’t like these or what but it does not grow like it should but I’ve had others that grow well.
