Substrate/soils for Walstad Jar


I have two bags of the nutrient rich soil from around my property. Mostly from underneath a rotting stump filled with nutrients and some ash from a burn pile.

I also have some sand for the capping layer from the property. But I might just use store bought substrate instead.

Any ideas regarding this? Is the soil good enough? And should I avoid using the sand I got from the property due to its higher soil content?

    You may end up with some loose soil out of that sand floating around the tank for a while. After it settles you may can just vac some of the dirt off of the top, the rest will work it’s way down slowly. Either way you need about double the sand as dirt, 1″ of dirt and 2″ of sand to cap it in.
