Mirror, Mirror on the Wall, Who’s the Easiest to Propagate of Them All? (Hint: It’s the Coprosma Propinqua!)
The Coprosma propinqua, also known as the mirror plant or the New Zealand looking-glass plant, is a hardy, versatile, and surprisingly easy plant to propagate. If you’re looking to expand your garden or share this resilient beauty with friends, propagation is the way to go. The best part? You don’t need a green thumb or a degree in botany to succeed.
Why Propagate?
Propagation is essentially creating new plants from existing ones. It’s a fun, rewarding, and often more economical alternative to buying new plants. For the Coprosma propinqua, propagation is remarkably simple, with high success rates, making it a perfect plant for even the newest gardener.
Two Paths to Propagation: Cuttings vs. Seed
You can propagate Coprosma propinqua in two main ways:
-
Cuttings: This is the most common and reliable method. It involves taking a cutting from a healthy plant and encouraging it to develop roots.
- Seed: While possible, propagating from seed can be a bit trickier. The seeds can be slow to germinate, and you may not get the same characteristics as the parent plant.
Let’s Get Down to Business: Propagating from Cuttings
Here’s a step-by-step guide to successfully propagate your Coprosma propinqua from cuttings:
Step 1: Timing is Everything
The best time to take cuttings is in late spring or early summer when the plant is actively growing.
Step 2: Gather Your Tools
- Sharp, clean pruning shears or scissors
- Small pots or seed trays
- Well-draining potting mix
- Rooting hormone (optional but recommended)
Step 3: Taking the Perfect Cutting
- Choose a healthy, non-flowering stem.
- Make a cut about 4-6 inches long, just below a leaf node (where the leaf joins the stem).
- Remove the leaves from the bottom half of the cutting.
Step 4: Prepping the Cutting
- Dip the cut end of the stem in rooting hormone (this encourages root development).
- Make a small hole in the potting mix with your finger or a pencil.
- Insert the cutting into the hole, ensuring the leaf nodes are buried.
- Gently firm the soil around the cutting.
Step 5: Creating the Ideal Environment
- Water the cuttings thoroughly.
- Place the pots or trays in a warm, bright location, but out of direct sunlight.
- Keep the soil consistently moist but not waterlogged.
- Cover the cuttings with a clear plastic bag or humidity dome to create a mini-greenhouse effect (this helps retain moisture).
Step 6: Patience is Key
It typically takes 4-6 weeks for cuttings to develop roots. You can test if roots have formed by gently tugging on the cutting. If there’s resistance, roots are likely developing.
Step 7: Transplant Time
Once the roots are established, you can transplant the cuttings into larger pots or directly into your garden. Gradually acclimatize them to their new environment by slowly increasing their exposure to sunlight.
