Left standing, ornamental grasses will have winter interest as well, providing movement and sound as the wind eases through their foliage. Ornamental grasses are extremely easy to plant and grow. Simply slip them out of the container in which they are growing and plant them at the same level in the ground. Grasses are tolerant of most soil conditions and they benefit from mulch. During their first growing season, feed them with a balanced fertilizer.
Ornamental grasses are undoubtedly one of the easiest types of plants to grow.
Most people leave the foliage on the plants to add winter interest. If your grasses are newly planted, cut them back to 3-4 inches in late fall and mulch them heavily to help them through their first winter. As soon as the snow melts in late winter, cut back all the old foliage. Leaving the foliage on too late in spring will actually inhibit new growth. It also makes it very difficult to remove the old growth without damaging the new.
