Switchgrass 'Squaw' Panicum virgatum 'Squaw'

Water

For the Switchgrass 'Squaw', water deeply to establish an extensive root system during the initial growth period. Once established, it is drought-tolerant and will require less frequent watering. Aim to water the plant every 7 to 10 days, providing about 1 to 1.5 inches of water each time. During periods of high heat or prolonged drought, you may need to water more frequently. It's best to check soil moisture levels before watering to avoid overhydration; the soil should be allowed to dry out slightly between waterings.

Light

The Switchgrass 'Squaw' thrives best in full sunlight, so it should be placed in a location where it can receive at least six hours of direct sun each day. It can tolerate some light shade, but too much shade can lead to weak growth and reduced vigor. The ideal spot for 'Squaw' is in an open area free of large trees or buildings that could cast significant shade.

Temperature

Switchgrass 'Squaw' is hardy and can tolerate a wide range of temperatures, but it grows best in a range of 60 to 75 degrees Fahrenheit. It can withstand temperatures as low as -20 degrees Fahrenheit and as high as over 90 degrees Fahrenheit. To ensure healthy growth, avoid planting it in spots where temperatures drop below the freezing point for prolonged periods or where summer temperatures consistently exceed the upper tolerance level.

Pruning

Switchgrass 'Squaw' benefits from pruning to maintain its shape and promote vigorous growth. Prune in late winter or early spring before new growth begins. This allows the plant to focus energy on producing fresh, healthy shoots. Cut back the foliage to about 4 inches above the ground. Pruning annually will help prevent the center of the plant from dying out and encourage a fuller appearance.

Cleaning

As needed

Soil

Switchgrass prefers a well-draining soil mixture with the ability to retain some moisture. A mixture of loam, sand, and peat with compost added for fertility is ideal. The preferred pH range for Switchgrass is slightly acidic to neutral, around 5.8 to 7.0.

Repotting

Switchgrass, being a perennial grass, does not typically require frequent repotting. It should be repotted or divided every 3-4 years to refresh the soil and manage its growth.

Humidity & Misting

Switchgrass is adaptable to a wide range of humidity levels and does not require any specific humidity conditions, thriving in the ambient humidity levels found in most outdoor environments.

Suitable locations

• Indoor

  Provide full sun through a window and well-draining soil.

• Outdoor

  Plant in sunny spot, water regularly, tolerate poor soils.

• Hardiness zone

  4-9 USDA

Life cycle

Panicum virgatum 'Squaw', commonly known as Switchgrass 'Squaw', begins its lifecycle with seed germination, typically in the spring when soil temperature warms. Seedlings emerge and establish a network of roots while shoots begin photosynthesis. The plant enters a vegetative stage characterized by rapid growth of long, narrow leaves and sturdy stems that can reach up to 6 feet tall. As the plant matures, it enters the reproductive phase, usually in mid-summer, producing airy, branched flower panicles. After pollination, seeds develop and are dispersed in late summer to fall, completing the life cycle. During winter, the above-ground parts die back, but the plant remains alive through its perennial root system, ready to regrow the following spring.

  Spring to Summer

• Panicum virgatum 'Squaw', commonly known as Switchgrass, is primarily propagated through division, which is the most popular method for this ornamental grass. Propagation by division is typically carried out in the spring, as the grass emerges from dormancy, or in the fall, once the growing season has ended. To propagate Switchgrass by division, a mature clump should be dug up and carefully separated into smaller sections, ensuring that each section has a portion of the root system attached. These divisions should then be replanted at the same depth they were previously growing, and watered thoroughly to establish them in their new locations. This method allows for the quick and effective multiplication of Switchgrass, while maintaining the characteristics of the 'Squaw' cultivar.
