Japanese Forest Grass

Hakonechloa macra, commonly known as Japanese Forest Grass, is a graceful ornamental grass appreciated for its arching, cascading foliage.

To ensure the health and beauty of this plant throughout the year, it's important to provide seasonal care tailored to its specific needs. This guide explains how to care for Hakonechloa macra throughout the seasons.

Spring

Pruning and Maintenance

In early spring, inspect your Hakonechloa macra for any dead or damaged foliage from the previous year and gently prune this away using clean, sharp secateurs to encourage new growth and maintain an attractive appearance.

Feed

Encourage new growth by applying a balanced, slow-release fertilizer. Follow the manufacturer's instructions for the correct dosage.

Watering

Gradually increase watering as the weather warms up. Keep the soil consistently moist but not waterlogged.

Summer

Mulching

Apply a 2 to 3-inch layer of organic mulch around the base of the plant to retain soil moisture, regulate temperature and suppress weeds. This is especially important in hot and dry summer conditions.

Watering

In the warmer months, Japanese Forest Grass requires regular watering. Keep the soil consistently damp but not waterlogged. Ensure it receives sufficient moisture during dry periods.

Autumn

Pruning and Maintenance

 As the growing season comes to an end, trim away any remaining dead or damaged foliage to tidy up the plant. Ensure not to over prune at this stage.

Protection from frost

Japanese Forest Grass is not fully frost-hardy, especially in colder regions. Consider covering the plant with mulch or frost cloth to shield it from freezing temperatures.

Winter

Pest and disease prevention

Pests and diseases are less active in winter, but it's essential to inspect your Japanese Forest Grass for any signs of issues and address them promptly
