What is the meaning of: Calamagrostis is a cool-season grass

When we say Calamagrostis is a cool-season grower, it refers to its growth and development cycle in relation to temperature. Here is what that means:

Active Growth in Cool Temperatures: Cool-season grasses, like Calamagrostis, start growing actively in early spring when temperatures are still relatively cool (around 40-75°F or 4-24°C). They continue to grow well through spring and into early summer.
Slow Growth in Summer Heat: As temperatures rise in mid-summer, their growth rate slows down. They might even go partially dormant during periods of intense heat or drought.
Rejuvenation in Fall: With the cooler temperatures of fall, cool-season grasses experience a renewed period of active growth.

What this means for gardeners:

Early Spring Emergence: You will see Calamagrostis green up and start growing early in the spring, often before many other plants.
Early Bloom Time: Cool-season Calamagrostis varieties like 'Karl Foerster' tend to bloom earlier in the summer compared to warm-season grasses.
Fall Interest: They often retain their green color or develop attractive fall foliage colors as temperatures cool down.
Planting Time: The best times to plant cool-season Calamagrostis are in spring or early fall when temperatures are moderate.

Contrast with Warm-Season Grasses:

Warm-season grasses, on the other hand, thrive in warmer temperatures (75-95°F or 24-35°C) and go dormant in winter. Examples include Big Bluestem (Andropogon gerardii) and Switchgrass (Panicum virgatum).

Understanding the growth cycle of cool-season grasses like Calamagrostis helps you choose the right plants for your climate and garden conditions and allows you to provide the best care for them throughout the year.

Do Calamagrostis Plants Attract Pollinators?

No, Calamagrostis plants are not considered to be particularly attractive to pollinators like bees, butterflies, or hummingbirds. This is because their flowers are small, inconspicuous, and lack the nectar or pollen rewards that pollinators typically seek.

The feathery plumes of Calamagrostis, while aesthetically pleasing, do not offer much in terms of sustenance for pollinators. Additionally, the timing of their bloom period often coincides with the abundance of other, more pollinator-friendly flowers, making Calamagrostis less competitive for pollinator attention.

However, Calamagrostis can still play a role in supporting healthy pollinator populations by providing:

Habitat and shelter: The dense clumps of Calamagrostis can provide shelter and nesting sites for some pollinator species, such as ground-nesting bees and butterflies.
Food source for other insects: While not directly attractive to pollinators, Calamagrostis can support populations of other insects that pollinators prey on, indirectly contributing to the food web.
Aesthetic value: By creating an attractive and diverse garden with a variety of plants, including both pollinator-friendly and non-pollinator-friendly ones, you can help to create a welcoming environment for all types of wildlife, including pollinators.

So, while Calamagrostis may not be a magnet for bees and butterflies, they can still be a valuable addition to a pollinator-friendly garden by providing habitat, shelter, and contributing to the overall biodiversity of the ecosystem.

Are There Any Common Pests Or Diseases That Affect Calamagrostis?

Fortunately, Calamagrostis are generally quite resistant to pests and diseases, making them relatively low-maintenance plants. However, there are a few occasional issues to keep an eye out for:

Divide in early spring, just as new growth begins to emerge from the base of the plant.

Fall:

An alternative option, especially for warmer climates.
Provides enough time for roots to establish before winter, but the plant will have less time to recover before the following growing season.
Divide in early fall, at least 6-8 weeks before the first frost.
Large clumps can be divided in fall with a good chance of flowering the following spring, while smaller divisions might require another season to reach full bloom.

Here are some additional factors to consider when deciding when to divide Calamagrostis:

Plant size and health: Dividing overgrown or congested clumps is beneficial for revitalizing the plant. However, avoid dividing small or weak plants, as they might struggle to recover.
Local climate: If you have harsh winters, dividing in spring might be safer to ensure the new divisions have enough time to establish before the cold weather arrives.
Specific species: Some species, like Calamagrostis x acutiflora 'Karl Foerster', can be divided in either spring or fall with good results. Research the specific needs of your Calamagrostis variety.

Remember, regardless of the timing, proper division techniques are crucial for the success of the process. Ensure you have sharp tools, prepare the new planting locations, and water the divisions thoroughly after planting.
