It’s true when they say “it all starts with the soil”. Healthy soil will grow healthy plants and in return produce more flowers, fruits and veggies. There is much science behind your soil, it’s not just dirt you know. But, it doesn’t have to be a difficult process to have healthy dirt and vibrant plants.

Native soils are usually not that great in many areas. Over time, soil degrades and nutrients are washed away. That’s where soil amendments come into play. There are two in particular that are excellent choices and you won’t have to worry about whether or not it will work with your soil… It will improve it.

Rock Dust is a mineral fertilizer and Agrowinn is the best on the market. It provides macro & micro nutrients to your soil. It can be used on all varieties of plants, trees and vegetables so you’ll have the added convenience of using the same product for all the plants around your landscape. This slow release product is super fine (like powdered sugar) and can be applied as a wet foliar with boom-type sprayers (diaphragm pump) or a dry application by simply sprinkling it around the base of your plant to top-dress the soil surface.

Rock Dust Mineral Fertilizer is made from volcanic rock. It has many advantages including bringing nutrients to the root zone where it’s needed the most. Applying Agrowinn’s Rock Dust Minerals during the first three-quarters of the growing period will correct many nutrient deficiencies.

These minerals are so fine, that less product is needed. This natural inorganic dust is consumed by microbes very easily, then it’s discharged organically which becomes available food for your plant. The warmer the climate, the more microbes that are available to create plant food.
