DIY Bees Nests for Solitary Cavity-Dwellers
Here's Project Manager, Susan Chan, demonstrating how to utlize an invasive plant like Phragmites to the benefit of bees and your garden. Simply harvest the stems in the fall, and create nests for solitary, cavity-dwelling pollinators, like leafcutter bees and mason bees.
This would be a great project for you and the kids during the off-season. If you made several of these to be scattered around your property in the early spring, you could potentially increase the numbers of pollinators in your garden by a large margin.
