Attributes of Scratch grass

Growth Rate

With a moderate growth rate, scratch grass experiences consistent development during Spring, Summer, and Fall. The uniform speed of growth promotes steady leaf production and height increase. Visible changes during the active growing season include fuller foliage and a slight increase in overall plant height. Horticultural interests may note less dramatic but sustained growth compared to high-speed counterparts, offering balance to landscapes.

Water: Scratch grass thrives in variable moisture conditions, requiring a moderate watering schedule of once a week. Its resilience allows it to adapt to somewhat moist and slightly dry environments, with growth influenced by seasonal rainfall patterns.

Fertilize: Fertilize scratch grass seasonally with a 2-inch layer of mulch or compost to promote vigorous growth and root stability. Apply in spring and fall, avoiding over-fertilization. Adjust based on scratch grass's growth phases and seasonal needs to ensure health and vitality.

Pruning: Scratch grass, with its fine texture and sprawling growth, benefits from early spring pruning. Trim dead stems to encourage healthy growth, but avoid heavy pruning. Light shaping maintains vigor, prevents overcrowding, and enhances air circulation, ultimately promoting a tidy appearance and robust health.

Propagation: Scratch grass can be propagated through division by splitting the root clump into sections with a strong root system and multiple shoots. Transplant into well-draining, organic-rich soil, ensuring consistent moisture and shade initially to promote healthy growth and genetic integrity.
