MCG doesn't have trees overhead but recommends that leaves not be bagged. Instead, leaves can be swept into the garden and used as mulch. Furthermore, they decompose and supply the garden with nutrients. You can even mow-and-mulch them so they break down faster. The Canadian Wildlife Federation has this and more ideas.

Natural bee nest material is recommended over commercial ones as advertised in Garden Making. Bundling 20 cm hollow stems such as daylily works well and can be composted after a season of use. Commercial products can harbour pest or disease, so require thorough annual cleaning.
