Austromyrtus dulcis

The Story

Plant Bio

Austromyrtus dulcis, commonly known as midyim berry, is a spreading, multi-stemmed evergreen shrub native to eastern Australian coastal heathlands and open woodlands. The small, lanceolate leaves are glossy dark green above and pale grey underneath, with new growth emerging in shades of coppery-pink.

Solitary white flowers appear in spring and summer, followed by edible, sweet, speckled grey-white berries that attract native birds and mammals. The dense, arching habit provides low-level shelter for wildlife while tolerating coastal salt spray and sandy soils.

Uses & Benefits:

Practical UsesProduces abundant edible, sweet berries and serves as an effective, salt-tolerant coastal groundcover or low hedge.

Planting

How to Grow

  1. Select a planting site with sandy, well-drained soil in full sun to partial shade.
  2. Dig a hole twice the width of the root ball and backfill, ensuring the plant sits at the same soil level as in the pot.
  3. Apply a thick layer of organic mulch to retain soil moisture and suppress weeds, keeping it clear of the main stems.
  4. Water deeply and regularly during the first summer to establish the root system and support fruit development.

Pro Tip

Prune lightly immediately after the autumn harvest to maintain a dense shape and encourage fruiting wood; cutting back hard into old, leafless stems will prevent reshooting.

Keep It Thriving

Care Guide

Do

  • Mulch the root zone to conserve soil moisture during hot dry spells.
  • Water regularly while fruit is setting to prevent berry drop.
  • Apply a low-phosphorus native fertiliser in autumn after harvesting.

Don't

  • Do not plant in heavy, waterlogged clay soils with poor drainage.
  • Do not prune hard into old, leafless woody stems.
  • Do not use overhead irrigation late in the day, which encourages rust.
