Transplants should be spaced approximately one foot apart. Mulching with three to four inches of clean straw helps keep weeds down. One weeding may be required the first growing season. Once established, little if any further weeding should be necessary. Most prairie flowers and grasses are warm season plants which germinate best after soil temperatures have warmed up.
Grasses do best with spring and summer seedings.
Planting in spring or early summer allows for better pre-planting weed control than fall seeding. Prairie plantings can be successfully seeded through mid-July. Fall seeding can be very successful, too, especially on dry soils. Fall plantings on dry soils allow seeds to germinate in early spring and become established before the heat of summer. Clay soils can also benefit from fall plantings.
