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!

Fantastic Results — Just Be Ready for the Smell!
Neptune’s Harvest Fish & Seaweed Fertilizer is an absolute game changer for my garden! My plants have never looked so healthy and vibrant — I’ve seen stronger growth, greener leaves, and even better blooms since I started using it. It’s easy to mix and apply, and a little goes a long way. The only downside is the smell — it’s definitely fishy (as expected), so be prepared when you open the bottle or apply it. But honestly, the results are so worth it that I’m happy to deal with the odor. Highly recommend for anyone serious about giving their plants a natural boost!

Big Yields, Beautiful Plants, Fair Price
My tomatoes and herbs love it. So do my houseplants. I love it for two reasons: One, it helps me get big vegetable yields and grow beautiful plants. Two, it's all natural. As for the price, it's fair. Not the cheapest fertilizer on the market, but it's worth every penny.

Love this stuff
I think this is a great organic fertilizer that can be used throughout your garden whether your plants are in the ground, potted, or indoors for seedlings or established plants. I highly recommend it. All of my plants love it and it is not harsh on any of them. Definitely follow the instructions on the bottle. The key for me is to not water the plants right before. If it is for potted plants and depending on the size I do little by little. Then after I finish I will go back to the first one to see if it needs more. You don't want the fertilizer draining out of the bottle - you want to make sure it all stays in the soil. This is fermented fish and seaweed so the concentrate in the bottle does have a punch as expected but once it is diluted there is barely any smell or any off putting smell. That is also why I do little by little so the fertilizer does not drain down into the drip trays. I can see it making the smell stronger as it evaporates.

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 roses, herbs and all other perennials love this stuff! Everything is growing, so many new shoots and the blooms are beautiful! So far, so good…Wish the bottle was a little bigger though!

If I could give this 10 stars I would! Garden is sprung to life, everything is dark green and vibrant. I give half the dose of what is required and I am still impressed with the results. I've uses countless high end fertilizers, but this one is the real deal. I am growing everything from cannabis, squash, beans, greens and flowers, etc.
