Question 2

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

Accepted Answer

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.

Question 3

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

Accepted Answer

Your maple needs iron like someone else posted. So no, this product is not enough because you need the IRON!

Question 4

is this Spike for Dogwood Trees?

Accepted Answer

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.
