Rated 4 out of 5 by from Amazing Results When Used In Moderation Neptune's Harvest products are excellent at building the soil in your garden and this liquid fertilizer doubles as a foliar spray. In my experience, the label suggests to use too much product and it can damage your plants. A teaspoon per gallon of water is more appropriate as a general guideline. All summer, I used a Tablespoon in a two-gallon watering can and my results were excellent. The yield of green beans was crazy by sprinkling this fertilizer on the leaves in late evening (once a month). The same results with pepper plants, pounds of fresh peppers came out of a small garden. Even marigolds had amazing color and the size of the plants became huge.. I've been using fish/kelp products for many years and diluting the product to 1/4 the recommendation prevents your garden from looking sick from too much of a good thing.
