We Get Questions
I recently purchased some Ultra Soil and noticed that it contained lots of seeds. Do you know what these might be (photo attached)? The seeds in the photo are from one trowel-full of soil.
The seeds are “Grape Pomace” which is the seeds and skin solids of wine grapes left over after the “wine crush”. It is used as an organic way to adjust the pH of the soil and compost. It is a long lasting component in the rice hull compost we use in our soil blend, the rice hulls which are the bulk of the compost, are the little slivers that sort of look like tiny canoes that you can see in our mix. Occasionally we also have to add additional Pomace to our finished blend, if the lava and coconut coir we use in the soil mix, are not acid enough to get the pH where we want it. As the Pomace breaks down it also gives micro-nutrients to the plants. Grape Pomace is also great to use on blueberries, rhododendrons and azaleas because it acidifies the soil. And since it is a local by-product it also helps us fulfill our goals of sustainability.
