Blue Oat Grass Care Must-Knows
Plant blue oat grass in full sun and well-drained, average-to-dry soil such as that found in rock gardens and curbside planting beds. (Crown rot is a risk if this grass is grown in poorly drained soil.) Water newly planted clumps of blue oat grass every week or so for the first growing season to encourage a strong root system. Supplemental watering is rarely necessary after the first year. Remove old foliage at the beginning of every growing season before new foliage emerges. Cut the foliage back to about 3 inches above ground level. During late winter (between early February and the end of March) is a great time to snip away old foliage. Use a manual or powered hedge trimmer for quick and easy stem removal. Blue oat grass can be divided every three or four years in spring. Dig up the entire clump, then use a sharp spade to slice it into three or four pieces. Replant the divisions and water them regularly to encourage strong root growth. Divide blue oat grass plants with these tips.
