Review: You will not regret buying it - Love it. Use every year in the past 3 years late spring/early summer by mixing into soil for fruit trees, grapes, vegetables, flowers. Natural product that helps get better harvest and improve soil.
Review: Outstanding product and company. Here's how I use it. - This kelp meal is a terrific amendment for adding nutrients and micro nutrients to help feed your soil and ultimately feeding your plants. This organic kelp meal is ascophyllum nodosum, which is among the finest available and truly does work. I use it in a few ways. Directly from the bag I will broadcast and mix the dry ingredients, following the application instructions on the back of the bag, into my garden soil, or my own homemade potting soil. Another way: I will rehydrate a cup of the kelp meal, once hydrated I then add it to a blender and emulsify, pour into a mason jar, cover and place in fridge for later use. When time to use, I add a teaspoon or so to a couple gallons of water, mix thoroughly, then water my plants with the mixture. One other thing I do is add a tablespoon or so of the hydrated/emulsified kelp meal to my aerated compost and vermicompost teas which I make in a five gallon bucket. My vegetables, roses, and other plants respond rather well to the nutrient rich waterings. My experience has also shown me there is no fear in burning my plants as this is organic and not filled with salts or synthetics like other fertilizers. Lastly, the reason I chose Neptunes Harvest is with the research I have done, they appear to be legit and care about their customers. It comes in a nice bag too! Ultimately great product and I will definitely be buying again. I hope this review helps and if anyone has any questions please feel free to email me which can be found on my profile page. Good gardening and happy harvest to you all.
