I used it first on my Angel Trumpet Trees and they began blooming profusely within days. (See photo). I counted 11 blooms one day! I'm now using it weekly on my vegetables and flowers. I'm on my 2nd bottle because I have a large container garden which requires watering more often. This is now my gardening staple...my plants are happy and healthier. I highly recommend this product!!! ### ⭐⭐⭐ I just expected it to be better homogenized. The cap isn't sealing reliably so shaking ... *by H***Y on Reviewed in the United States on May 1, 2017* I bought this as a supplement for my African Violets.It is odorless, but has numerous clumps in it so that I can't dispense it with a pipette. Shaking vigorously didn't help. That's not a deal breaker. I just expected it to be better homogenized.The cap isn't sealing reliably so shaking it each time I use it is a nuisance.It's too soon to judge whether it has helped my plants. ### ⭐⭐⭐⭐⭐ Used this product for a couple of root feedings and the plants responded nicely.

Used this product for a couple of root feedings and the plants responded nicely. Have started using sea kelp(not this brand) for root and foliage feedings. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/15064026-organics-rx-sea-kelp-100-seaweed-fertilizer-18-fl-oz](https://www.desertcart.jp/products/15064026-organics-rx-sea-kelp-100-seaweed-fertilizer-18-fl-oz) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-29*
