Today, I’m going to tell you all about green sand. Here is a bag of green sand; I have a big bag because I use it in my Green Gourmet house plant food, but they do come in smaller packages.
So, what is green sand? It is a naturally occurring marine sedimentary deposit, coming from the ocean floor. It is comprised primarily of the blue-green silicate mineral glauconite. Green sand is traditionally used to loosen heavy clay soil or to hold together loose sandy soil, making it beneficial for outdoor gardening. It can also absorb up to one third of its weight in water, improving the moisture-holding capacity of potting soils and garden soils.
This is one of the reasons why it’s really good to add green sand to your potting soil or existing soil. Additionally, it promotes plant vigor by providing plants with iron, which is an essential micronutrient. Iron plays a crucial role in promoting photosynthesis and helps plants produce chlorophyll. In this way, green sand acts not only as an amendment but also as a micronutrient fertilizer. It also assists plants in moving oxygen through their systems and contributes to their green color.
Interestingly, green sand has been recommended as a soil amendment since the 1700s, meaning it has been used for a long time. Obviously, it has been around much longer in the ocean, but its application in gardening has also existed for quite some time.
Let me show you what it looks like. It actually looks like green sand; it has a green hue, kind of an army green, but definitely green. It behaves very much like sand, as you can see it slipping through my gloves.
So now you know what green sand is and why you would want to consider adding it to your house plant soil, using it as a fertilizer amendment for your plants. As mentioned, it is also included in my potting soil and my fertilizer.
