## 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.
