Neptune's Harvest Seaweed Fertilizer 0-0-1, Gallon

This stuff works great for all plants. I use it on everything. I either use it every watering or every other watering depending on the type of plant, and how much of it I have left (sometimes I have to stretch it out until I get more) It's definitely one of the cheaper amendments available (in liquid form anyways) Neptunes harvest is one of the most underrated brands out there, you really can't go wrong with any of their products, and this one is probably their best one. The fish fertilizer is great as well, but this one is the best bang for your buck in my opinion.

Im not sure if its been mentioned yet, but this stuff is amazing rooting stimulator for cannabis. Seaweed and kelp are full of incredible rooting hormones. I use this stuff at 10ml per gallon in conjuction with 20 ml per gallon of Rhizotonic and my cuttings and baby plants explode with growth, and thick, healthy roots.

Nothing really.

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 kelp fertilizer, it is so mild I almost wouldn't consider it a fertilizer, it's more of a multivitamin for your plants/soil. I use it either every other watering or every third watering for seedlings. This helps prevent any early issues and gives the plants a great start, and it's so gentle you dont have to worey about overdoing it and causing issues with young seedlings. I cant think of another fertilizer that you can apply to brand new sprouts and they'll just take off and love it! 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 so gentle.For more established plants I would use this product in conjunction with higher strength organic fertilizers to help give the plants micronutrients, since most NPK fertilizers are often have little or no micronutrients. 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 also use this product when I first hydrate new potting soil mix to help the beneficial microbes come alive and get established.I haven't discovered a time when this product causes any issues at all, and the plants seem to love it. To me this product is more for preventing plant issues than it is a fertilizer. Keep in mind that if plants have access to all the nutrients, micronutrients, minerals that plants actually defend themselves from pests and stressors. If your plant is truly healthy, insect pests usually leave your plant alone and search for a weaker plant to take advantage of. Imagine being an aphid and trying to suck on the plant. First thing that deters you is the plant is a tougher to bite into than usual. Hmm, not the end of the world but also not ideal. Ugh this plant tastes horrible because the plant produced it's own defensive chemicals and hormones. You can take a bite or two but now you don't feel so well, again because the plant has made some defensive toxins and stored them in the cells for defense. These toxins do not impact the plant but can mess up the digestive tracts of pests. Put yourself in the insects place. Would you want to stay on this healthy plant and continue to essentially be poisoned and everything you try to do is more difficult? No, your instinct is to move along and find a much easier target...another plant that isn't doing as well and has a compromised immune system and defenses. In fact, insects have evolved to literally smell the distress signals of plants and they seek out weak and easy meals. Your neighbor's fruit and vegetable garden is perfect because they use Miracle-Gro or some other synthetic fertilizer that doesn't supply the plants full needs, just the ones necessary to grow large and have a lot of energy. To insects these plants are essentially fast food because there's tons of calories and nothing stopping them from eating. Now because your neighbor has all these pest problems, they will be sure to apply synthetic pesticides because these products are right next to the Miracle-Gro! Now your neighbor has created a viscous cycle where the very products they apply are damaging their ecosystem more than helping it, and they will always be constantly applying synthetic fertilizers, herbicides, fungicides etc because otherwise their gardens or farms would collapse without the aid of these tools. This is perfect for the fertilizer companies (which also own the companies that make pesticide, herbicide, etc). They have a repeat customer for life! Nothing is better for a corporation than steady, reliable income.Haha I really went on a tangent there, but just know that this product is a great tool to supply the natural plant and soil ecosystem to keep things healthy!

This really kicked my plants into overdrive. Most especially, my Christmas cacti...they all have amazing new growth since using this. All of my plants look healthier and shinier. This bottle will last forever!

This product is amazing really. It says it’s seaweed but it’s really kelp. Kelp has natural hormones in it that stimulate growth. Use this along with a good microbe mix anytime you transplant or stress your plants, maybe with pruning injury, or flipping to flower. This will cause the plants to not have any shock symptoms like wilting or no/slow growth. There’s virtually zero recovery time for the plants due to the kelp.I will never be without this.

Neptune's Harvest Seaweed Plant Food: I have used this organic supplement for years. Studies have been done that indicate that seaweed extracts are beneficial to plants, in terms of increasing health and hardiness. Also, for me, it is a big plus that this supplement is approved for use in organic production. I have found it very useful in transplanting new plants (or for that matter, old plants!) into new locations, and as a general "tonic" for plants. Please bear in mind that this particular plant food provides micronutrients, and is not a "total" fertilizer. You still need to provide your plants with good growing soil - which for me, means organic compost mixed with garden soil and some long term slow-release organic fertilizers like bone meal, composted manure and\or a good organic slow-release granular fertilizer, well mixed into the soil. This seaweed plant food is certainly not the cheapest plant supplement you can buy, but I think you get what you pay for, in this case. Just mix it with water in the amount directed; you can use it as either a foliar feed or a root feed - I prefer watering at the roots, as I live in an area with high summer humidity, and prefer not to have wet leaves, particularly overnight.

I have a small strawberry patch and for the first time ever, I used fertilizer on them this year. I started with this back in February, and fed them once a month since, with this paired epsom salts. They not only started giving me berries a week, or so, earlier than previous years, they aren't done yet. Normally they only give me berries for two weeks, tops, and I'm already almost two weeks in. The berries are bigger, not as odd shaped, sweeter and juicer, than ever before. I'm very pleased with the results, and will definitely buy this again.

I’m very happy with my purchase, thank you

Very happy with this product this is my first time buying this seaweed at first i was hesitant to buy because I thought my plants will stink like fish but I was wrong this product is odorless and my plants are growing happy I am very happy definitely I will recommend this product

This stuff is made from seaweed...it actually does make your flowers and veggies grow like a weed..I will definitely keep buying this awesome fertilizer and recommend you do the same.

Just came in yesterday haven’t had time to tried it yet but the bottle had a leaky cap and spill in the wrapping. Something the manufacturer should be careful
