Planting Tips

Where to Plant

Karl Foerster Feather Reed Grass thrives in a spot that receives full sun to partial shade. It’s perfect for open areas in the garden where it can soak up the sun for at least six hours a day. Avoid overly shaded areas for optimal growth.

Light

This grass prefers full sun but can tolerate partial shade. Sunlight is crucial for its growth, ensuring the best flowering and upright form. In too much shade, it may not bloom as vibrantly and can become leggy.

Soil

Karl Foerster Feather Reed Grass is not fussy about soil types. It adapts well to most soil conditions, preferring a well-draining soil. It can tolerate clay, sandy, or loamy soils, making it versatile for different garden settings.

Spacing

When planting, give each clump of Karl Foerster Feather Reed Grass about 18 to 24 inches of space. This spacing allows each plant to grow to its full size and ensures adequate air circulation, reducing the risk of disease.

When to Plant

The best time to plant Karl Foerster Feather Reed Grass is in the spring or early fall. Planting during these cooler seasons allows the grass to establish its root system before the extremes of summer heat or winter cold.

How to Plant

Planting is straightforward – dig a hole twice as wide as the root ball and as deep as the container. Place the plant in the hole, fill it with soil, and water thoroughly. Ensure the crown of the plant is level with the soil surface.

Plant Care Tips

Watering

Regular watering is essential during the first growing season to establish a deep, extensive root system. Once established, Karl Foerster Feather Reed Grass is relatively drought-tolerant but benefits from occasional watering during prolonged dry spells.

Fertilizing

Minimal fertilization is needed. If desired, apply a balanced, slow-release fertilizer in early spring to encourage vigorous growth. Avoid over-fertilizing, as it can lead to floppy growth.

Pruning

Pruning is minimal – simply cut back the foliage to about 4-6 inches from the ground in late winter or early spring before new growth starts.

By Season

 

Spring Care

In spring, remove old foliage and apply a layer of compost or slow-release fertilizer to promote healthy new growth. This is also the ideal time for dividing the plants if necessary.

Summer Care

During summer, Karl Foerster Feather Reed Grass is low maintenance. Ensure it receives enough water during extremely hot or dry periods to keep it looking its best.

Fall Care

In fall, the grass requires little care. It can be left as is to add winter interest to the garden. If necessary, you can tidy up the plant by removing any dead or discolored leaves.

Winter Care

Winter care is minimal. The grass can be left standing to provide winter interest and habitat for wildlife. Cut back the foliage in late winter to make way for new spring growth.
