- Water
To water Japanese forest grass properly, ensure the soil is kept evenly moist, particularly during the first growing season to establish a deep root system. Water the plant thoroughly once a week with about 1.5 gallons of water, but adjust this frequency to maintain soil moisture without waterlogging, especially during hot or dry periods. During the winter, reduce watering as the plant requires less moisture. A good practice is to check the soil moisture by touching the soil; if the top inch feels dry, it's time to water again.
- Light
Japanese forest grass flourishes in light conditions that provide it with partial shade to full shade. The ideal spot for this ornamental grass would be an area that receives filtered sunlight or morning sun followed by afternoon shade. Too much direct sunlight, particularly in hot climates, can cause the foliage to scorch.
- Temperature
Japanese forest grass grows best in temperate conditions and can survive a wide range of temperatures but thrives between 40 and 85 degrees Fahrenheit. It can withstand cold down to about -20 degrees Fahrenheit and can tolerate summer highs up to around 90 degrees Fahrenheit, but prolonged exposure to temperatures beyond this range can be harmful.
- Pruning
Prune Japanese forest grass in late winter or early spring before new growth starts. Cut back the foliage to about 2-3 inches from the ground to remove any dead material and encourage fresh, healthy growth. Pruning once a year is usually adequate.
- Cleaning
As needed
- Soil
Japanese Forest Grass thrives in a well-draining soil mix with organic matter such as compost or peat moss incorporated. The best soil pH for Hakone Grass is slightly acidic to neutral, ranging between 5.5 and 7.0.

- Life cycle
Hakonechloa macra 'Alboaurea', commonly known as Golden Variegated Hakone Grass, begins its life cycle when the seeds germinate in the spring, given moist soil and cool temperatures. The seedlings establish a strong root system and start producing the characteristic arching, variegated blades of foliage. Throughout the spring and summer, the plant grows vigorously, forming dense, cascading clumps that reach up to 18 inches in height. In late summer to early fall, the grass may produce airy, green to reddish-brown flower spikes that stand above the foliage. After flowering, the grass enters a period of senescence in the fall as temperatures drop, and the foliage typically takes on pink or reddish hues before dying back to the ground. During winter, the plant is dormant, but it regrows from the crown (the perennial base of the plant) when the next spring arrives, repeating the life cycle.
- Propogation
Propogation time
Spring to summer
The Hakonechloa macra 'Alboaurea', commonly known as the Golden Japanese Forest Grass, is typically propagated through division, which is best done in the spring. This method involves taking a mature clump of the grass and carefully splitting it into smaller sections, ensuring that each new section has a piece of the root system attached. The divisions are then planted in a well-prepared soil mix, maintaining the same depth as the original plant. Keep these new plants well-watered and shaded until they establish themselves, allowing a successful start to their growth. Division helps to invigorate older clumps and is an easy, reliable way to increase the number of plants in your garden while maintaining the traits of the original cultivar.
