Scheduling Maintenance on a Rhizome Trap (Sand Trench)

Many people choose to use a sand trench to manage their bamboo. It is simply a 14" deep trench filled about 12" with sand. To maintain, simply take a flat-bottom spade and sink it into the sand, cutting through and rhizomes that have passed through. Pull the spade up and move to the side, making sure to overlap about an inch and repeat, until you've gone down the entire line. We find 100' takes about 15 minutes. Below is the schedule:
