Taming the Coastal Beauty: Propagating the Thick-Leaved Mahoe (Melicytus crassifolius)
The Thick-leaved Mahoe, or Melicytus crassifolius, is a captivating New Zealand native with a rugged charm. This coastal evergreen shrub, boasting small, leathery leaves and fascinating, almost hidden, flowers, can be a stunning addition to gardens that embrace a touch of seaside wilderness. However, finding this beauty in nurseries can be a challenge. The solution? Propagation!
Propagating Melicytus crassifolius might seem daunting, but fear not! With a bit of patience and the right approach, you can successfully grow new plants and welcome more of this coastal gem into your garden.
Two Paths to Propagation:
1. Seed Propagation:
This method, while rewarding, requires patience as it can take a year or more to produce a substantial plant.
- Seed Collection: Source seeds from ripe fruits, identifiable by their purplish-black color. Remove the fleshy pulp, as it can hinder germination.
- Sowing: Use a well-draining seed raising mix. Sow seeds on the surface and lightly cover them.
- Patience is Key: Keep the mix consistently moist but not waterlogged. Germination is slow and erratic, often taking several months.
- Transplanting: Once seedlings develop a strong root system and several true leaves, transplant them into individual pots with a free-draining mix.
2. Cutting Propagation:
A faster alternative, producing results within a few months.
- Timing is Crucial: Take semi-hardwood cuttings in late summer or early autumn when the plant is actively growing.
- Choosing the Right Cuttings: Select healthy stems that are about 10-15cm long, ideally with a heel (a small section of the older wood attached).
- Preparation: Remove lower leaves, leaving 2-3 at the tip. Dip the cut end in a rooting hormone to stimulate root development.
- Planting: Plant the cuttings in a mix of coarse sand and potting mix, ensuring good drainage.
- Creating a Humid Environment: Cover the pot with a plastic bag or use a propagator to maintain humidity and warmth.
- Transplanting: Once roots develop and new growth appears (usually within a few months), transplant cuttings into individual pots.
General Care for your New Melicytus crassifolius:
- Sunlight: These plants enjoy full sun to partial shade.
- Soil: Well-drained soil is crucial to prevent root rot. Incorporating sand or grit into heavier soils can help.
- Watering: Water regularly during the first year, especially during dry spells, but avoid overwatering.
- Fertilizing: Feed in spring with a slow-release fertilizer to support healthy growth.
- Pruning: Light pruning after flowering can help maintain shape and encourage bushier growth.
