Mulching a Wildflower Meadow for Moisture Conservation and Reseeding

A zone 5 gardener asks the best mulch for a full-sun wildflower area to conserve moisture but allow self-seeding.

Wildflower meadows generally don't need added mulch. Natural processes suffice:

Mow or burn late in season after seed set.
Mowing creates a light mulch of cut stems.
If burning, mulch with leaves that don't mat heavily (avoid maple leaves). Shred leaves first with mower or chipper.

Thick mulch prevents seed contact with soil, inhibiting germination. Wildflowers need light and soil contact to reseed naturally.
