What Is Karl Foerster Feather Reed Grass?
Karl Foerster Feather Reed Grass is a cool-season ornamental grass known for its upright growth habit and feathery flower plumes. It begins growing early in the spring, often before many other grasses wake up, bringing life to the landscape when little else is growing.
The plant produces narrow, deep green blades that grow straight up instead of arching outward. By late spring to early summer, tall flower stalks rise above the foliage, topped with soft, wheat-like plumes. The plumes start out with a pinkish or purplish tint before maturing into a warm golden tan.
One of the most appealing features of this grass is that it plumes very early in the season. And even better, it holds its shape all season long. Even after the flowers fade and dry, the plant remains upright and attractive through fall and winter.
Why It’s So Easy To Grow
One of the biggest reasons Karl Foerster Feather Reed Grass is so popular is how easy it is to care for. Once established, it requires very little attention to thrive. It does not demand frequent watering, heavy fertilizing, or constant dividing like some other ornamental grasses.
It is also highly adaptable. Karl Foerster grows well in a wide range of climates and performs reliably in both full sun and partial shade. It tolerates cold winters and hot summers equally well, making it a great choice for gardeners across many growing zones.
Another key advantage is that this grass is sterile, meaning it does not reseed or spread aggressively. It stays neatly in place, forming a well-behaved clump that slowly increases in size without taking over surrounding plants.
Last but not least, with its popularity, it is easy to find for purchase. Most nurseries and on-line nurseries carry the grass for sale. Affiliate Link: Feather Reed Grass Karl Foerster 4 Inch Container | Ornamental Grass Drought Tolerant
Planting For Success
Karl Foerster grass prefers full sun, where it will grow tall and produce the strongest flower plumes. However, it can also tolerate partial shade, especially in hotter climates. In shadier locations, it may grow slightly shorter and produce fewer flowers, but it will still remain healthy.
Soil type is rarely an issue. Karl Foerster grows well in average garden soil, sandy soil, and even heavier clay soils as long as there is decent drainage. While it does not like standing water, it can handle occasional wet conditions better than many other ornamental grasses.
Once established, the plant is drought tolerant. Regular watering during the first growing season helps develop strong roots, but after that, you will rarely if ever have to water.
When To Plant & Divide
Planting Karl Foerster is simple and straightforward. Spring and early fall are the best times to plant. This allows the roots to establish before extreme temperatures arrive.
Karl Foerster typically grows about four to five feet tall and two to three feet wide. Be sure to allow for that growth when picking a planting spot. Always dig the hole slightly wider than the root ball and just as deep. Place the plant in the hole so the top of the root ball sits level with the soil surface.
Backfill with soil, gently firming it around the roots. Water thoroughly after planting to remove air pockets and help the plant settle in. Adding a light layer of mulch around the base is a must. This will help retain moisture and regulate soil temperature.
Maintaining Karl Foerster Feather Reed Grass
One of the greatest benefits of Karl Foerster Feather Reed Grass is how little maintenance it requires. There is no need for regular trimming, shaping, or staking during the growing season.
The only routine task is cutting the grass back once a year. In late winter or very early spring, before new growth begins, cut the plant down to about four to six inches tall. This removes old growth and allows fresh blades to emerge cleanly. See our article: 3 Great Reasons To Leave Your Ornamental Grasses Up All Winter Long.
Fertilizing is usually unnecessary. In fact, too much fertilizer can cause the plant to grow too quickly and lose its upright form. If soil is extremely poor, a light application of compost in early spring is more than enough.
Dividing the plant is rarely required. Karl Foerster grows slowly and maintains its shape for many years. If the clump becomes too large after several seasons, it can be divided in spring to create new plants.
Without Worry Of Pests And Problems
Another reason Karl Foerster is so easy to grow is its resistance to most pests and diseases. Deer and rabbits typically avoid it, making it a great choice for gardens where wildlife browsing is a concern.
It is rarely affected by insect problems, and fungal diseases are uncommon when planted in well-draining soil. Good air circulation and proper spacing help prevent any potential issues, but most gardeners never encounter problems at all.
Because it is sterile and non-invasive, there is no worry about it spreading into unwanted areas or crowding out other plants. One thing is for sure – Karl Foerster Feather Reed Grass is truly one of the most versatile ornamental grasses available – and can be a great addition to your landscape!
