Great fertilizer - fishy smell
This is a great fertilizer. Some people don’t like to use this inside because of the slight fishy smell. As for me, It is worth it.

Highly recommend!
Started using last year and was more than impressed with the results. Used on seedlings and had the healthiest I have ever had. Used throughout the year and had the best harvest I have ever had. Highly recommend!

Stinks, but my plants love it!
I have to admit, this stuff smells pretty strong — definitely not something you want to sniff too closely. That said, I’ve been using it on my indoor plants and they are thriving! Leaves are greener, plants are bushier, and they just look so much healthier since I started using it. If you can handle the smell, it’s totally worth it. My plants are loving it, and that’s all that really matters!

Works well but it’s very concentrated
Neptune has always been my go-to fertilizer but you have to hold your breath when mixing it and be very careful with the dilution ratio. This is the 1st time I have ever used it for seedlings. Instead of 1 tsp per cup of water, I used a half tsp and it still burned my tomatoes (at 6 inches tall, they were more mature than seedlings), and caused purple leaves overnight. Also, my bottle was so poorly packaged, it leaked all over the plastic bag it was wrapped in. It’s great stuff, just be careful with it.

Made my Garden Gorgeous
I am absolutely thrilled with Neptune's Harvest Fish & Seaweed Fertilizer! This gallon-sized bottle of liquid gold has transformed my flowers and vegetable gardens into lush, thriving paradises. Let's start with the results. Since incorporating this fertilizer into my gardening routine, the difference in my plants' growth and productivity has been nothing short of astounding. My flowers are bursting with vibrant colors, and my vegetable garden is yielding an abundance of healthy, delicious produce. From tomatoes to zucchinis, everything seems to be thriving like never before. What sets this fertilizer apart is its natural and sustainable formulation. Made from a blend of fish and seaweed, it provides a rich source of nutrients that are essential for plant growth. The 2-3-1 NPK ratio ensures a balanced diet for my plants, promoting strong root development, vigorous foliage growth, and prolific flowering and fruiting. I also appreciate the convenience of the liquid form. It's easy to apply with a watering can or spray bottle, and it's quickly absorbed by the plant's roots, delivering nutrients where they're needed most. There's no need to worry about measuring or mixing; simply dilute as directed and watch your garden thrive. Another fantastic aspect of Neptune's Harvest is its versatility. Not only is it suitable for flowers and vegetables, but I've also used it on my lawn, shrubs, and even indoor plants with fantastic results. It's truly a one-stop solution for all my gardening needs. And let's not forget about the environmental benefits. Neptune's Harvest is derived from sustainable sources and is safe for use around children, pets, and wildlife. Knowing that I'm nourishing my garden in a responsible and eco-friendly way gives me peace of mind. In conclusion, Neptune's Harvest Fish & Seaweed Fertilizer has exceeded my expectations in every way. Its natural formulation, exceptional results, and ease of use make it a garden essential that I can't recommend highly enough. If you want to take your garden to the next level and enjoy bountiful harvests and beautiful blooms, look no further than Neptune's Harvest.

Perfect for Seedlings - BONUS: Deer Hate It!
My bottle came in a plastic bag, tightly closed, so I didn't have the spillage issues others have described. I also get this delivered in January or February where heat is not an issue. I grow my seeds in soil blocks which means I have no trays of standing water. As a result, I don't have the smell issues. Once my soil blocks wick up the liquid, things get neutralized or something like that. (My seedling mixture is coir and earthworm castings.) I fertilize seedlings once a week at half the rate recommended in the bottle. When it comes to the outdoor gardens, well, that's a whole 'nother story. I only feed my herb/vegetable gardens on Mondays when I know that no one is coming over for a barbecue that smells like a bad fish fry. If I can time this so that it rains that night, even better for me. If I have bad weather, I fertilize later in the week but no later than Thursday. That smell will linger for a day or two, especially in hot, humid weather. The benefit of the lingering is that the deer HATE this. Their sense of smell is 50 times stronger than ours so if I'm smelling this stuff for two days, I know they're smelling it too, for a lot longer. This is part of my KTDA (Keep The Deer Away) strategy, and even though I live in the middle of wildlife management where deer pressure is nuts, I never have a problem with deer in my two-acre, seven-garden property. (But I am disciplined and consistent with keeping up with the deer situation.) You do have to shake this bottle before every use and you have to do it vigorously. Mix only what you are going to use; once the solution is mixed with water, it begins to break down. Don't store it in your shed or garage where you'll experience extreme temperature swings. I've never had a problem with the stench sticking to plastics but I do soak my plastic sprayer bottle in a solution of borax and water once a week in a five-gallon pail and throw in all the other stuff that's gotten grungy during the week. It's not an inexpensive product but the yield you'll get from your vegetable garden will more than cover the cost. I grow flowers to benefit my vegetables and I do find that they are more fragrant than flowers that are fertilized with other products. Fragrance is critical in keeping deer away so this is important to me. I haven't seen a drop in beneficial insects or non-beneficials, for that matter, so the only beast that seems to be offended by the smell are the giant rats with hooves that would love to enter and make a buffet out of my place. But with confidence, use as directed, and if the smell is really too much to bear and deer are not a problem, feed the soil and skip the foliar feedings.

Works great
It smells awful but it works. One bonus of the bad smell is it helps keep the deer away from the garden. My flowers were very happy this season.
