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!

My Magical Neptune Elixir
I use this on my garden one week out of the month, with regular fertilizer two weeks of the month, and also regular bone meal. I did notice that when I use this kelp stuff, it seems to generate new roots from the base of the plant, get stronger, and producing more fruits and veggies! These things are most likely to happen during/after kelp week. This stuff goes a long way for a small bottle. It dissolves perfectly, and there is a very faint ocean smell to the water when it is mixed in. Nothing terrible smelling. We’ve been using this product for years in our garden, and it truly gives an extra boost to any plants. Our garden truly thrives, and produces so many fruits and vegetables. We use it on almost everything: our flowers, strawberries, blueberries, melons, tomatoes, lettuce, garlic, cucumbers, onions, peppers, carrots, squash plants and more! Fish and Seaweed are known to build the natural sugar in plants. Flowers and foliage will be stronger and more colorful. Adding this to your garden will give you better vegetables/fruit yields. This is a great fertilizer for a few key reasons: The first is that it's a great source of Phosphorus which is used by new plants to produce strong roots and so is great for any root vegetables! This is a secret ingredient that all gardeners use to improve their garden! I highly recommend using for your plants!

i bought this a few years ago. the product is very good if you're willing to pay that much for it. the problem i have with it that it lost a star for is theyre using cheap plastic for the bottle. i know most people will use it quick enough not to care but it should be considered. since i had it sitting so long i was "shaking it vigorously" and the plastic disintegrated and the emulsion splattered over everything. now, if you've never smelled fish emulsion, you're in for a treat. if you ever smelled rancid meat, you're getting close. all over me and my garage floor... my two yorky mixes came from across the yard to try to lick it up (they LOVE the smell!). very frantic 10 minutes for me trying to clean up the garage, my clothes, my hair etc. and keep the dogs from licking the floor, as well as my shirt and pants and hair etc etc.... so.... good product but they got cheap with the plastic.

Little bit goes a long way.
This stuff smells so terrible just want to warn everyone when they first open it DO IT OUTSIDE. But my plants seem to be thriving ever since I started using this fertilizer. I think plants may vary but all my pepper plants seem to like 1 table spoon per gallon. The first time I watered them I added 1/2 table spoons per gallon and the leaves showed signs of burning which goes to show how strong and concentrated this little bottle is. But after my 2nd watering and lowering the concentration seems to be the sweet spot and they haven’t showed any burning since

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.
