Planting and Care Guide for Hakonechloa Macra

Proper planting and care helps ensure Hakonechloa macra thrives in your landscape. Follow these tips for success:

Site Selection

  • Choose an area with partial to full shade, or dappled sunlight. Avoid hot afternoon sun.
  • Provide shelter from strong winds which may damage the arching foliage

Soil Preparation

  • Amend soil with compost or leaf mold to improve drainage
  • Maintain evenly moist soil, not soggy or bone dry
  • Ideal pH is neutral to slightly acidic

Planting

  • Space plants 12-18 inches apart in staggered rows
  • Dig holes the width of the root ball and 1.5 times the depth
  • Set root ball slightly high, top of roots at soil level
  • Backfill with native soil, tamp gently to remove air pockets
  • Water thoroughly after planting

Growing Conditions

  • Thrives in part sun to full shade
  • Tolerates a range of soil types, from sand to clay
  • Requires consistently moist soil, avoid extremes of drought or waterlogging
  • Hardy to USDA zones 4-9
  • Peak foliage colour in partial sun; more lime-green in deep shade

Care

  • Water 1-2 inches per week, more in extreme heat, less if rainy
  • Apply balanced fertilizer in spring and fall
  • Cut back old foliage in late winter before new growth emerges
  • Remove weeds and clear debris around plants
  • Mulch annually with 2-3 inches of organic matter
  • No major pest or disease problems

Propagating Hakonechloa Macra

Hakonechloa macra can be readily propagated by several methods. This allows you to expand your plantings for free.

Division

  • Divide in early spring as new growth starts
  • Use a shovel to slice through the clump, retaining 3-5 culms per division
  • Replant divisions 15 inches apart
  • Keep soil evenly moist while roots establish

Seed Sowing

  • Sow seeds indoors in flats in late winter
  • Barely cover seeds with soil, keep humid and 65-70F
  • Transplant seedlings after 4-6 weeks
  • Seedlings may take 2+ years to reach mature size

Division is the easiest method and preserves desired plant characteristics. Tissue cultured plants offer a fast option but lack the maturity of older plants. Seed propagation is possible but very slow to establish.

Troubleshooting Common Problems with Hakonechloa Macra

Browning Leaves

  • Causes include drought stress, excessive sun, or overfertilization

Stunted Growth

  • Often due to excessive shade or root competition
  • Increase sunlight where possible
  • Clear away grass and weeds from base of plants

Pest Problems

  • Main pests are spider mites, aphids, or scale
  • Treat with horticultural oil or insecticidal soap sprays
  • Improve plant vigour to resist pests
