  • Great growth stimulator
Size: Quart (32 oz)
I recently stated using the kelp/seaweed liquid. I have noticed greater grow and stability in my plants. No foul orders when using.

  • It might not be organic but it works really well
Size: Gallon (128 oz)
This product is great because it doesn't stink at all like other kelp products, it has very little to no scent. I use it on my houseplants and succulents, it is a revolutionary kelp extract because it does not smell. BUT There is no proof that it is organic and for that reason it will never touch my edible crops. I have communicated with Bloom City Organics requesting documents proving their products were organic, and they could not produce any documents whatsoever. I do not consider the sellers word to be proof that the product is organic and for that reason I will not be using this product on my food crops. I like it a lot for houseplants, don't get me wrong but there's no way I'm putting this product on my organic food crop without organic registration or third party oversight to ensure it is actually organic. Unfortunately I bought two different products from this company, Bloom city organics. Seems kindof fishy that a company would be named Bloom city organics without any organic certification for their products. See for yourself, there's people reviewing this product saying things like they "believe it to be organic". I'm not a believer. If Bloom city produces some kind of proof their products are organic, I will foliar feed every single plant I have with it. I look forward to seeing their products as a registered for organic gardening. Edit: Bloom city refunded me for the product since I wasn't happy about the lack of proof the product is organic. I have to say Bloom city has great customer service and they really care about their products. Like I said before this is great for foliar feeding your plants without any smell I use it on my indoor plants because I can't stand the smell of kelp in my house. I recommend this product for any situation where you want to foliar feed without the nasty smell of kelp. ... show more

  • It will work!
Size: 1/2 Pint (8 oz)
This product is not overhyped. I’m astonished at how well, and quickly, it has helped my plants! I’ve had a struggling houseplant, which didn’t respond to other interventions. I stumbled upon an organic gardening site that raved about the benefits of seaweed, so I decided it was worth a try. I chose this brand based on the rating and reviews, plus the small bottle size and great price. I’ve been using it for 2 weeks, adding it in my weekly watering. I’m blown away by the improvement in all my plants, even those I believed were fine. One plant is beginning to bloom for the first time in years! For my houseplants, this bottle will last several months. I’m ordering a larger size for use on my potted plants outside. ... show more

  • Helps during Rainy season
Size: Quart (32 oz)
This is one of the better liquid kelp products I haved used. Another popular brand sold on Amazon and elsewhere I tried a couple of years ago and I didn't care for it as I did not see any results. Bloom City's kelp I can use without combining with other fertilizers and see micronutrient deficiencies reverse out. Florida's fertilizer ban period is during our rainy season from June to September 30th. My town's ordinance does not allow for nitrogen or phosphorus fertilizers during this time and this is one of only a few fertilizers I can use during this period. In 2020 and 2021 we had heavy daily rains that caused whatever slow release fertilizer you put down before the ban period to degrade faster resulting in nitrogen and micronutrient deficiencies during the ban period. While you can use other products to help with the micronutrient deficiencies, you have to wait it out for October 1st for a nitrogen application. It's August 2022, we've had daily rains with some exception days and so far our fruit trees, shrubs and other outdoor plants are green. The kelp by itself and combined with other non nitrogen non phosphorus fertilizers have kept our plants green. I like this product a lot; I combine it with other non npk fertilizers and use it as a soil drench and foliar spray. The product is thick and I have used it in replacement of soap or in combination with soap as an emulsifier for my diy essential oil pesticide sprays. The product works well for me so far and if we get through September and remain green I'll know this product is one I must have for all other rainy seasons. ... show more

  • Amazing, concentrated, and no odor at all
Size: Quart (32 oz)
This concentrate is absolutely amazing. It's so concentrated that you only need 1 tsp. per gallon of water. It has no odor at all. It works great as a foliar mist on my epiphyte-type houseplants (goldfish and lipstick plants) and outdoor potted petunias., etc. It really helps with transplant shock. It will revive plants that have begun to wilt-I accidentally broke off a cherry tomato vine and put it in a jar of the solution, sprayed it a few times, and it recovered (even though it was almost too wilted) enough for me to plant it, and it's doing fine. This is the best liquid kelp I've ever used and I've been gardening for 40 years. ... show more

  • Works Well For My Succulents
Size: 1/2 Pint (8 oz)
This has a strong smell when you first open the bottle but will dissipate after you add water. I've been using this to help my succulents root for 5 months. All are doing well, no signs of over fertilized. The leaves are nice and fat, roots on cuttings are growing and bare root succulent made a quick recovery. I also use this for any green plants inside the house and on my tomato plant. ... show more
