How to Care for Blue Grama Grass: Tips and Tricks
If you’re looking for a versatile and easy-to-grow grass that can thrive in harsh conditions, blue grama grass is an excellent choice. This warm-season grass is native to the Great Plains of North America and has been used as a forage crop for both livestock and wildlife. In recent years, it has gained popularity as an ornamental grass due to its unique texture, low-maintenance requirements, and tolerance for drought, heat, and cold. Whether you want to plant blue grama grass in your lawn, meadow, or garden, here are some tips and tricks on how to care for it.
Choosing the Right Site and Soil
Before you start planting blue grama grass, you need to select a suitable site and prepare the soil. This grass prefers full sun, well-drained soil, and low to moderate fertility. It can tolerate a wide range of soils, including sandy, loamy, or rocky soils, as long as they are not too wet or alkaline. If your soil is heavy clay, compacted, or nutrient-poor, you may need to amend it with organic matter, such as compost, manure, or peat moss, to improve its structure and nutrient content.
When choosing a site, keep in mind that blue grama grass may not grow well in areas with high humidity, shade, or competition from other plants. It also needs enough space to spread out and form clumps, which can be up to 3 feet wide and 1 foot tall. Therefore, avoid planting it near trees, shrubs, or buildings that can block the sun or limit the air circulation.
Planting and Watering
The best time to plant blue grama grass is in the spring or early summer, when the soil temperature is above 60°F and the risk of frost has passed. You can plant it by seed or sod, depending on your preference and budget. If you choose to plant by seed, you can either broadcast it over the soil surface or drill it into shallow furrows. The recommended seeding rate is about 2-4 pounds per 1000 square feet. To ensure good seed-to-soil contact, you can rake the soil lightly after sowing and cover the seeds with a thin layer of mulch or straw.
After planting, water the soil lightly but frequently, keeping it moist but not soggy until the grass has established. This may take several weeks or months, depending on the weather, soil conditions, and watering schedule. Once the grass has rooted deeply and shown signs of growth, you can reduce the frequency and amount of watering, allowing the soil to dry out slightly between waterings. Blue grama grass is relatively drought-tolerant and can survive without irrigation during periods of low rainfall, but it may benefit from occasional soaking during prolonged dry spells.
Fertilizing and Pruning
Blue grama grass does not require much fertilization or pruning, but it may benefit from occasional applications of balanced fertilizer or compost to promote healthy growth and color. You can apply the fertilizer or compost in early spring, before the grass starts to grow, or in late summer or fall, after the grass has gone dormant. Avoid over-fertilizing or using high-nitrogen fertilizers, as they can stimulate excessive leaf growth and reduce the quality of the grass.
As for pruning or cutting back blue grama grass, you can do so in late winter or early spring, before the new growth emerges. This will help remove any dead or damaged leaves, as well as promote new growth from the base. However, be careful not to cut the grass too short or too often, as this can weaken the roots and make the grass more susceptible to pests, diseases, or weather stress.
Pest and Disease Control
Blue grama grass is generally resistant to most pests and diseases, but it may encounter some problems under certain conditions. For example, it may attract grasshoppers, armyworms, or webworms during hot and dry summers, or fungal diseases like rust or smut during humid and rainy periods. To prevent or control these issues, you can use cultural, mechanical, or chemical methods, depending on the severity and type of problem.
Cultural methods include improving drainage, reducing shade and humidity, and avoiding over-watering or over-fertilizing. Mechanical methods include handpicking or vacuuming the pests or diseased parts, mowing or burning the affected areas to remove the sources of infection, or using barriers, traps, or nets to exclude the pests. Chemical methods include applying insecticides, fungicides, or herbicides, but these should be used only as a last resort and according to the label instructions.
Blue grama grass is a hardy and attractive grass that can add value and beauty to your landscape. By following these tips and tricks on how to care for it, you can enjoy its benefits without much effort or expense. Remember to choose the right site and soil, plant and water properly, fertilize and prune moderately, and prevent or control pest and disease issues. With a little patience and attention, you can create a lush and sustainable habitat for yourself and your ecosystem.
