Kelp is an important nutrient!

This liquid kelp is a fertilizer that promotes root growth, blooming, and enhances the health of the soil. It may be applied as a foliage spray. I would recommend it.

Great Plant Boost!

I use very sparingly each water on my young tomato plants and they're visibly healthier and more vigorous after just a couple of weeks .

I like that it's a natural ingredient product. It has a strong sulphur smell that may be unpleasant to some.
