Are these (Jobe's Organic Tree Fertilizer Food Spikes) worth while. Anybody have any experience using them?
I have two trees that aren't looking so healthy. One I believe is a Pin Oak and the other a white ash. They were planted about 2 years ago and looked fine last year but not so good this year.
I'll also accept other ideas to fertilize these trees along with white pines and a Japanese cherry tree (think that's what it's called).
