Seasonal Interest

Spring

In spring, new growth emerges, starting the transformation of the garden. The fresh, green leaves of Hakone Grass begin to unfurl and sway in the breeze.

Summer

During summer, the grass reaches its peak, displaying lush, vibrant foliage. Some varieties may change color, adding bright yellow or golden hues to the garden.

Fall

In fall, Japanese Forest Grass can turn to shades of copper and red, adding a warm tone to the autumn garden. Its texture remains appealing even as temperatures drop.

Winter

In winter, the grass may fade to tan or brown but often retains its form. Its presence adds interest to the winter garden, contrasting the bareness of other plants.

Planting Tips

Where to Plant

Japanese Forest Grass thrives in part to full shade. It is ideal for planting under trees, on the north side of buildings, or in any garden area that does not receive intense midday sun.

Light

While it can tolerate some morning sun, this grass prefers shaded conditions. Too much direct sunlight can scorch its delicate leaves and diminish its vibrant colors.

Soil

It grows best in moist, well-draining soil rich in organic matter. Japanese Forest Grass can tolerate a range of soil types but prefers slightly acidic conditions.

Light

Space plants about 18 to 24 inches apart. This allows each plant to spread and fill in the area, creating a lush, continuous ground cover.

When to Plant

The best time to plant Japanese Forest Grass is in the spring or early fall. Planting during these cooler seasons allows the grass to establish its root system.

How to Plant

Dig a hole as deep and twice as wide as the root ball. Place the plant in the hole, backfill with soil, water thoroughly, and apply a layer of mulch to conserve moisture.

Plant Care Tips

Watering

Water regularly to keep the soil consistently moist, especially in the first growing season. Once established, Japanese Forest Grass is somewhat drought-tolerant but performs best with regular watering.

Fertilizing

Fertilize in early spring with a balanced, slow-release fertilizer. Over-fertilizing can stimulate excessive growth at the expense of the plant’s form and color.

Pruning

Pruning is not typically necessary. However, you can trim back the foliage in early spring to remove any winter-damaged leaves and encourage fresh growth.

By Season

 

Spring Care

In spring, clean up any winter debris, apply a light fertilizer, and ensure adequate watering as new growth emerges.

Summer Care

During summer, maintain consistent soil moisture. Japanese Forest Grass does not require extensive care during this season.

Fall Care

In fall, prepare the plant for winter by reducing watering. You can also add a layer of mulch for added winter protection.

Winter Care

Japanese Forest Grass is relatively low-maintenance in winter. In colder climates, the grass may die back but will re-emerge in spring.
