Multiply Your Myoporum: A Simple Guide to Propagating Thick-Leaved Boobialla
The Myoporum crassifolium, more charmingly known as the Thick-leaved Boobialla, is a versatile and robust evergreen shrub native to Australia. With its attractive grey-green foliage, ability to withstand coastal conditions, and charming white or pink flowers, it’s no wonder this plant is a popular choice for gardens and hedges. If you’re looking to expand your Myoporum collection or share its beauty with friends, propagation is surprisingly easy.
This guide will take you through two common methods for propagating your Thick-leaved Boobialla:
1. Propagation from Cuttings:
This method mimics the natural rooting process and is the most common way to propagate Myoporum crassifolium. Here’s what you need:
- Timing is Key: The ideal time to take cuttings is during the active growing season, from late spring to early autumn.
- Sharp and Clean: Use a sharp, clean pair of pruning shears or a knife to avoid damaging the parent plant and ensure a clean cut.
- Selecting Your Cuttings: Choose healthy, non-flowering shoots from the current year’s growth.
- Preparing the Cuttings:
- Cut a 4-6 inch section from the tip of the shoot, making the cut just below a leaf node (where the leaf joins the stem).
- Remove the lower leaves from the cutting, leaving 2-3 leaves at the top.
- If desired, dip the cut end in rooting hormone powder for faster root development.
- Planting the Cuttings:
- Fill small pots or a seed tray with a well-draining potting mix.
- Make a hole in the soil with a pencil or your finger and gently insert the cutting.
- Water the cuttings well, ensuring the soil is consistently moist but not waterlogged.
- Creating a Humid Environment:
- To increase humidity and promote rooting, cover the pots or tray with a clear plastic bag or a propagation dome.
- Place the cuttings in a bright location, out of direct sunlight.
- Patience is a Virtue: It can take 6-8 weeks for roots to develop. Gently tug on the cutting – resistance indicates roots have formed.
- Transplanting: Once the roots are established, transplant the rooted cuttings into individual pots or your desired garden location.
2. Propagation from Seed:
While less common, Myoporum crassifolium can be grown from seed, offering a rewarding experience for patient gardeners.
- Collecting the Seeds: After flowering, the Thick-leaved Boobialla produces small, fleshy fruits. Collect the ripe, dry fruits and extract the seeds.
- Preparing the Seeds: Soak the seeds in warm water for 24 hours to improve germination rates.
- Sowing the Seeds:
- Fill seed trays or pots with a well-draining seed-starting mix.
- Sow the seeds about 1/2 inch deep and cover lightly with soil.
- Watering and Warmth:
- Water the seeds gently, ensuring the soil is moist but not soggy.
- Place the seed tray in a warm, bright location but out of direct sunlight.
- Germination: Germination can be erratic and may take several weeks or even months.
- Transplanting: Once the seedlings are large enough to handle, transplant them into individual pots.
A Few Tips for Success:
- Well-Draining Soil: Whether propagating from cuttings or seeds, use a well-draining soil mix to prevent root rot.
- Avoid Overwatering: Water the cuttings or seedlings only when the soil is dry to the touch.
- Patience is Key: Remember, propagation takes time. Don’t be discouraged if you don’t see results immediately.
By following these simple steps, you can easily propagate your Thick-leaved Boobialla and enjoy its beauty in multiple locations for years to come. Happy gardening!
