Mauget Inject-A-Min Iron Zinc Tree Fertilizer Injector - Fast-Acting Nutrient Supplement for Trees, Shrubs & Plants - Perfect for Arborists, Gardeners & Landscapers (Use for Nutrient Deficiency Treatment & Tree Health Maintenance)

We tried this product out on a couple of our maple trees that were starting to go chlorotic because of our alkaline soil (previous owners should have planted different trees). We didn't really see any results from this product so either the trees were too far gone for the season, we drilled the holes too deep (since the instructions aren't too clear on depth), or it just doesn't work. For the price I'd expect better results or at least better instructions.Great buyNot work for my treesOne of my trees, leaves from few branches will starts browning and fall early. Like this week (late June) eadges leaves starts browning already.Another tree lacks of leaves, I used this product according to product recommendation but doesn't seem like it helps at all.
