Multiply Your Myoporum: A Simple Guide to Propagating this Hardy Native

Myoporum tetrandrum, also known as Boobialla or simply Myoporum, is a favourite for Aussie gardens. This versatile native boasts lush foliage, attractive flowers, and a hardiness that makes it a breeze to care for. Want to expand your garden’s Myoporum population without breaking the bank? Propagation is the answer! This guide will walk you through two successful methods for multiplying your Myoporum:

1. Propagation from Cuttings

Taking cuttings is the most common way to propagate Myoporum, and for good reason – it’s straightforward and boasts a high success rate. Here’s how:

Timing is Key: The ideal time to take cuttings is during the cooler months, from late autumn to early spring.

Tools of the Trade:

  • Sharp secateurs or pruning shears
  • Seedling raising mix or a well-draining potting mix specifically for cuttings
  • Small pots or seedling trays
  • Rooting hormone (optional but recommended)

Let’s Get Cutting:

  1. Select Your Cuttings: Choose healthy, non-flowering stems from the current season’s growth. Each cutting should be around 10-15cm long.
  2. Prepare the Cuttings: Remove the leaves from the bottom third of the stem. If using rooting hormone, dip the cut end into the powder or gel, following the product instructions.
  3. Potting Up: Fill your pots or trays with moist seedling mix. Make a small hole in the centre and carefully insert the cutting, burying the bottom node (where the leaves were removed).
  4. Creating a Humid Environment: Cuttings thrive in warmth and humidity. You can achieve this by placing a clear plastic bag over the pot or using a propagation dome. This helps retain moisture and promotes root development.
  5. Location, Location, Location: Place your cuttings in a well-lit area but out of direct sunlight.
  6. Patience is a Virtue: Keep the potting mix consistently moist but not waterlogged. In a few weeks, you should start to see new growth, indicating successful rooting.

2. Propagation from Seed

While slightly less predictable than cuttings, Myoporum can also be propagated from seed. Keep in mind that plants grown from seed may not be identical to the parent plant.

Sourcing Seeds: You can collect seed capsules from your Myoporum plant (once dry) or purchase seeds from a reputable nursery.

Sowing the Seeds:

  1. Prepare a Seed Tray: Fill a seed tray with a good quality seed raising mix.
  2. Sowing: Sow the seeds thinly on the surface, lightly covering them with a sprinkle of the mix.
  3. Water Gently: Use a fine mist spray to water the seeds, ensuring not to dislodge them.
  4. Warmth and Light: Place the seed tray in a warm, bright spot, out of direct sunlight.
  5. Germination Time: Germination can be erratic and may take several weeks or even months.

Transplanting Your Success:

Once your cuttings or seedlings have developed a strong root system and are showing signs of healthy new growth, it’s time to transplant them. Choose a well-drained spot in your garden that enjoys full sun to part shade. Water them well after planting and enjoy watching your Myoporum flourish!

With a little patience and these simple tips, you can easily propagate your own Myoporum plants. It’s an affordable and rewarding way to expand your garden with these beautiful and resilient Australian natives.
