What month is best to plant wildflower seeds?
The best time to plant wildflower seeds depends on your region, but early spring or late fall generally provides optimal conditions for seed germination. Choosing a diverse wildflower seed mix supports a variety of blooms throughout the season, benefiting pollinators like bees and butterflies. Once you’ve prepared a weed-free seed bed with moist soil and raked it level, you can mix wildflower seeds with a little sand to make it easier to sow them and then scatter the mix evenly across the bare soil. This is a fairly easy method, but generally not as reliable as planting out plugs.Firm and rake the surface to make a seedbed. Don’t be tempted to add manure or fertiliser as this will encourage excessive vigour in the grasses, which then swamp the wildflowers. This is the most important principle in establishing a wildflower meadow. Sow in autumn, giving the seed time to settle in over winter.
