How to plant wildflowers in Zone 5a.
Zone 5a has a long enough window to support both spring ephemerals and summer-peak perennials. Mow the area close before seeding to reduce competition. Rake to expose bare soil. Scatter seed and press in with a board or roller — no raking over. First mowing should be at 6 inches, timed to cut weed competition without topping the wildflowers.
