Neptune's Harvest Fish Fertilizer (2-4-1) - Organic Liquid Plant Fertilizer - Fish Hydrolysate for Vegetables, Flowers, Fruit, Trees, Grass - Indoor and Outdoor Plant Food (Quart)

Make no mistake - you do not want to touch it. Haha. I’ve set this up on a timer drip system for landscaping and garden now in two different properties. It’s amazing stuff. Plants loooove it. Water early morning for just 10 minutes and within a week, plants take off. Now it’s set to water it in every 3 days. Just remember - it smells horrid - so do not plan to touch it and then not scrub yourself down (which is why ours is on an automated drip system). Have recommended it to friends and everyone has had amazing results. They have a smaller size if you want to try it out but I’m sure once you set it up so you don’t have to touch it, you’ll be hooked too. Happy gardening!

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.

This is a great fertilizer for nearly all plants (succulents and cacti not so much).

I used to buy this brand's other product, the combined Fish and Seaweed liquid fertilizer. Buying the fish fertilizer and kelp fertilizer separately really helps you customize which nutrients to feed your soil/plants at various life stages. For this fish fertilizer, it is mild but plants actually love that in a fertilizer! Fish hydrolysate(what this product is) is actually supplying your plants with an abundance of amino acids. For the supplied amino acids, your plant now gets to skip making their own (which requires time and energy) and will graciously take this free energy and food and flourish! You don't have to worry about burning your plants with this product. I use it either every third or fourth watering for seedlings. I like to also use this brand's seaweed (or is it kelp?) Liquid in conjunction usually. This helps prevent any early issues and gives the plants a great start, and it's so gentle you don't have to worry about overdoing it and causing issues with young seedlings. I can't think of other fertilizers that you can apply to very young plants and not have to worry about overdoing things. If you applied even heavily diluted synthetic fertilizer you could easily burn your plants or kill seedlings. This is why so many experienced gardeners will tell you to use a weak soil and don't fertilize for quite some time until your seedlings are more established. This product is an exception to that rule because it is natural and gentle. For more established plants I would use this product in conjunction with higher strength organic fertilizers. Probably the most natural way to give your plants nutrients would be to top dress some organic fertilizer and add this product to your water and water those amendments in. I haven't discovered a time when this product causes any issues at all, and the plants seem to love it!

Took a couple weeks before it arrived, but so did everything else from diff sellers so that's ok. I've done a lot of research on fish fertilizers so I now know the diff between this "cold-pressed", and the emulsified stuff. I really like this so far. Since I have to "Top-Dress" every 4 weeks, I like to use this every other week because the nutes are soluble and that means my plants can feed right away while the microbes are slowly breaking down everything else. I've had absolutely no deficiencies this whole grow. Very impressed! Just shake it up real good before every application. The smell is not bad at all. Smells exactly like catfish bait and it doesn't smell up my grow room. I would choose this stuff every time!

Smell is rough but there is a noticeable difference in the plants fertilized with this stuff a little really goes a long way . I would purchase again tomato and strawberry plants had wayyyy more activity

This is amazing! Highly recommended. I shared some with family and they were also pleased

The smell is nasty, so lets just get that out of the way. That's the only negative. This stuff just WORKS. I'm obsessed. My plants love it. I put it in almost everything. Lemon trees, orange trees, strawberry plants, tomatoes, basil and other herbs. They all seem to love it and often there's almost immediate growth. It mixes easily enough. I throw some in a watering can, then fill up the can. While filling, it mixes fine. I haven't had any issues with it burning plants, but I always use it early in the AM or late at night. I recommend getting the larger size as I went through the little one too fast with my garden's size.

The delivery was speedy, and the product works as directed.

great product

Great for vegetable and flower garden. Quality is pretty good.

Great organic fish fertilizer, made my plants and flowers grow fast.

I would by it again when I need more. I put a full measured dose on my Habaneros pepper plants a few nights ago and woke up to deep green leaf and proud tall plants this morning. They look amazing! Can't wait to see how it affects the pepper production.
