The product seems to be exactly as advertised. It arrived promptly. I have used it and again, it is as advertised--smells like fish!! How does one tell, at this stage, whether a fertilizer product, applied this week, is going to produce the verdant growth that all gardeners dream about, but seldom achieve?? I trust that it will, but who knows whether the deer, the rabbits, the slugs, and a dozen other hazards will intervene. Using fish emulsion instead of 10-10-10 or some other bagged fertilizer makes sense to me, and it is much easier to use, so here goes!! The only reason I rate it with 4 instead of 5 stars is the uncertainty factor. Maybe I can give an update at the end of the growing season.
