This is an excellent product... a little on the pricey side but works great.

I use this on my garden one week out of the month, with regular fertilizer two weeks of the month, and also regular bone meal. I did notice that when I use this kelp stuff, it seems to generate new roots from the base of the plant, get stronger, and producing more fruits and veggies! These things are most likely to happen during/after kelp week. This stuff goes a long way for a small bottle. It dissolves perfectly, and there is a very faint ocean smell to the water when it is mixed in. Nothing terrible smelling. We’ve been using this product for years in our garden, and it truly gives an extra boost to any plants. Our garden truly thrives, and produces so many fruits and vegetables. We use it on almost everything: our flowers, strawberries, blueberries, melons, tomatoes, lettuce, garlic, cucumbers, onions, peppers, carrots, squash plants and more! Fish and Seaweed are known to build the natural sugar in plants. Flowers and foliage will be stronger and more colorful. Adding this to your garden will give you better vegetables/fruit yields. This is a great fertilizer for a few key reasons: The first is that it's a great source of Phosphorus which is used by new plants to produce strong roots and so is great for any root vegetables! This is a secret ingredient that all gardeners use to improve their garden! I highly recommend using for your plants!

It smells awful but it works. One bonus of the bad smell is it helps keep the deer away from the garden. My flowers were very happy this season.

Smells fishy, just like it should, light smell, easy to dilute and apply to plants, won’t burn plants
