This Product works.
Transplant Shock. I have tees thst need this product whenever transplanting. I don't use this as a fertilizer. But it does ignite plant growth I noticed. It is one of the gest products so far for both transplant shock preventative, plant and root growth. I ran out but would like to buy it again. Fertilizer quality: It has unexpected and excellent Quality. I get big leafes. Size: I live in a small space so the size of the product suited my situation. I am sure they come in different sizes, for different needs. I ran out and brought one on thr fly from Home Depot. Really not the same Quality. I said to myself, I wish I had this one again. I ran out. Happy this review came up so I can add this to my cart.

Good natural fertilizer with great results.
My husband swears by this product. Makes our flowers bloom like mad. It's easy to use and lasts quite a while, depending on how many flowers/plants you're treating.

A very healthy difference after just a couple of applications.
This Bloom City kelp fertilizer came highly recommended from my rose growing friends. I have a climbing rose that is over 150 years old. It had belonged to my great grandmother. I was so worried when this Spring it was looking great. It was suggested to use an organic approach to help regains it's health. I did the foliage spray the first week. It started perking up in a few days. Then I did the kelp fertilizer mixed in with the watering the following week. That was about 5 days ago. What a difference! Plus no worries about run off into the stream at the back of our property.

It might not be organic but it works really well
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.

The go to for growing healthy cannabis plants!
If you want happy healthy cannabis plants that pray all day this is the key! I recommend doing a foliar spray at 20ml per gallon. I have tried so many different kinds of kelp & products to boost your grow but this one always works! You will see instant results, healthy plants & vigorous growth. It also doesn’t have a bad smell like most kelp products.

Lush Growth, Minimal Effort — My Plants Are Thriving!
This kelp fertilizer is pure gold for any gardener. I’ve used it on everything from houseplants to veggies, and the results are consistently impressive. The blend of seven seaweed species gives my plants a noticeable boost in both root development and overall vitality. Leaves are greener, stems are stronger, and growth is faster. What I love most is how easy it is to use—just mix a small amount into your regular watering routine and let nature do the rest. There’s no risk of overdoing it, and it’s gentle enough for even the most delicate seedlings. Plus, it’s fully organic, which gives me peace of mind knowing I’m not introducing harsh chemicals into my garden. If you want a low-maintenance way to supercharge your plants, this is it. I’ll definitely be keeping a bottle of this on hand year-round.
