Intermediate Wheatgrass Plant Care

Intermediate Wheatgrass (Thinopyrum intermedium) belongs to the Poaceae family within the Thinopyrum genus. Intermediate Wheatgrass is native to Europe and Western Asia. Intermediate Wheatgrass is also known as Tall Wheatgrass.

Intermediate Wheatgrass displays a tall, upright grass growth habit, reaching up to 5 ft tall with a spread of approximately 2 ft. Intermediate Wheatgrass produces inconspicuous flowers on tall spikes.

Leaf size: approximately 12 inches.

Thinopyrum intermedium requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Intermediate Wheatgrass thrives in full sun to partial shade.

Thinopyrum intermedium grows best at temperatures of 60–85°F. Intermediate Wheatgrass prefers humidity levels of 40–70%.

Well-draining loamy soil with good organic content. Good drainage is essential for Intermediate Wheatgrass to prevent waterlogging, which leads to root rot and fungal issues.

Feed Intermediate Wheatgrass every 8 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Divide and replant every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Intermediate Wheatgrass can be propagated through division, seeds. Similar propagation techniques also apply to bluntflower wheatgrass plant care, which shares the same genus.
