Ornamental grasses are often undervalued as part of landscapes, but offer a lot in the background without demanding the attention of more showy counterparts in beds or borders. If you want to add drama to your yard, September is an ideal time to plant ornamental grasses from cooler climates.

So, why plant ornamental grasses in September? Let's consider what they contribute. Grasses add texture, colour, and movement, and they are low-maintenance. Sounds good, yes. Plus, early fall is a perfect time to plant them, as the soil is warm and moist, giving them enough time to settle and establish roots before winter.
