One of our new garden projects this summer was building a lasagna bed around the base of this Big-leaf Maple.
A house down the street put lots of flattened cardboard out for the taking.
It is the perfect 1st layer.
In the compost area there are piles of paper, coffee grounds, grass clippings, horse manure and leaves.
All of these were added in thin layers with a sprinkle of glacial rock dust every so often.
The pile was covered with cardboard and left to 'cook'.
A compost thermometer monitors the temperature and a water reader monitors the moisture levels.
We were careful to not build up the bed against the tree trunk.
Project updates coming.
