I recently started using Liquid Seaweed for Plants, and I must say it's been a game-changer for my garden. This concentrated liquid kelp supplement has proven to be a fantastic addition to my gardening routine, and I'm excited to share my positive review.

The concentration of beneficial nutrients in this supplement is impressive, and it has had a noticeable impact on the health and growth of my plants. The ease of use is a significant advantage. Mixing the liquid seaweed into my watering can or sprayer is simple and straightforward, thanks to the clear instructions provided. It seamlessly integrates into my regular watering and feeding routine, saving me time and effort. One standout feature is the natural and organic nature of this product. It aligns with my commitment to sustainable and eco-friendly gardening practices. Liquid Seaweed for Plants is free from synthetic chemicals and harmful additives, making it safe for both my plants and the environment. The results have been truly impressive. Since I started using this liquid seaweed supplement, I've noticed increased resilience in my plants. They've shown improved resistance to pests and diseases, and their overall vitality has improved significantly. The leaves are greener, the blooms are more vibrant, and my vegetables taste better. The quart-sized bottle provides an ample supply of liquid seaweed, ensuring that I have enough for multiple applications without needing frequent replenishment. This practicality adds to the overall value of the product. Furthermore, the reputation of liquid seaweed as a natural plant growth enhancer is well-established in the gardening community, and this product lives up to those expectations. In conclusion, Liquid Seaweed for Plants is a fantastic addition to any gardener's toolkit, especially for those looking to promote healthier and more resilient plants. Its quality, ease of use, organic nature, and impressive results make it a valuable asset in achieving a thriving garden.

  • Miracle worker for plants?
I only started dabbling in plants in 2020 so I had a lot to learn! Anytime I do transplanting, I always add this to it and so far none of my plants went into shock. This includes changing pots and moving from pots into the ground. It doesn't take very much either! Mix a little with water and it works well ... show more

  • Fast Acting
I needed a fast acting liquid fertilizer for my vegetable garden that was not too high in nitrogen. This worked well.

  • Must have!
I will never grow indoor plants without this product again! I just dipped my toe into the world of Crazy Plant Person and after seeing someone on TikTok use another seaweed product I figured I’d try. I chose this product for its price—figured if it didn’t work I wasn’t out much. IT WORKS. I have a brown thumb, but this stuff works. I put a few capfuls in a large dishpan and fill it with a few gallons. Then I set my plants in the solution so they can soak through the bottom. Not only are the plants thriving, but the burst of growth is insane! My monstera is throwing new leaves all the time, as are the dozen other plants I sit in it every single week. They drink what they need, and whatever they drink is like natural plant steroids. Highly recommend! ... show more
