Horsetail?
View attachment 2346763
Do I make tea? Always looking for better/natural (cheap?
) sources of grow material...
Thats the one! compost it, make a tea, topdress/mulch, personally I like to add as an amendment to the soil mix, slow release over time, 1 cup per 1cuF or so, or whenever i have it. Some info from around the net:
Horsetail contains high concentrations of silicic acid and other silicates. Horsetail also contains potassium, aluminum, and manganese, along with variety of flavonoids
The silicon content of the horsetail is the highest in the entire plant empire, and no other herb comes even near to the silica levels found in the plant
