Today's plantings are an "experiment."
Little trees are paired and tagged. One will be planted normally and the other with a cup of "biochar" included. Progress can be monitored!
Biochar holds water like a sponge, where plant roots can access it when they need it. This is especially helpful during periods of hot, dry soil conditions.
Biochar helps conserve plant nutrients by storing them and making them readily available when plants need them.
