i've been using neptune fish fertilizers for awhile, when my plants look a little limp and maybe overwatered, these help revive plants. I use them on my avocado trees, my blueberry plants and other vegetables and they all do well when i feed them a twice sometimes more a year watering with this concentrated fertilizer. Yes it smells, but it works. It's interesting that a broken down animal like fish can fertilize a plant, like it feeds on the protein, so not sure how it works, but just found it interesting and great that it works so well.

I’ve used this fertilizer now for the last two years and bought it again this year, because I found it works very well with my vegetables. I would recommend to a friend…

Love this stuff for my leafy plants. Been applying it on my cabbages, spinach,kale and chard this fall. Just wow! They love it. Be sure to switch it up in the late spring/early summer tho, as it will attract slugs and snails.
