Hey there, fellow plant pals!
If you’ve ever admired those carpets of exquisite, feathery foliage gracing garden beds or spilling from containers, chances are you’ve met Leptinella squalida. This little charmer, often called Brass Buttons or New Zealand Brass Buttons, is a gem for its low-growing habit and intricate, fern-like leaves that can range from bronzy-green to steely grey. It’s one of those plants that just makes you smile when you see it thriving.
The best part? Propagating these beauties is incredibly rewarding. You get to bring forth new life, fill more of your garden with their charm, or share them with friends. I find Leptinella squalida to be quite forgiving, making it a wonderful project, even if you’re just dipping your toes into the world of propagation. Let’s get our hands dirty and make some more of these lovely plants!
The Best Time to Start
For Leptinella squalida, your best bet for propagation success is during its active growing season. This usually means late spring through to mid-summer. When the plant is really putting on growth, it has more energy to dedicate to forming new roots. I’ve had decent luck with divisions even in early autumn, but spring and early summer give you a head start so your new plants have plenty of time to establish before cooler weather sets in.
Supplies You’ll Need
Gathering your tools beforehand always makes the process smoother. Here’s what I usually have on hand:
- Sharp pruning shears or a clean knife: For making precise cuts.
- Rooting hormone (optional but recommended): Encourages faster and stronger root development. I like using a powder or gel.
- A good quality potting mix: A light, well-draining mix is key. I often use a blend of peat moss or coco coir with perlite or coarse sand.
- Small pots or trays: Clean ones, of course! Seedling pots or even recycled yogurt cups will work.
- Watering can with a fine rose: To gently water your new cuttings.
- Plastic bags or a propagator: To create a humid environment.
- Labels: So you don’t forget what you planted where!
Propagation Methods
Leptinella squalida is quite amenable to a couple of different propagation techniques. Here are my favorites:
1. Stem Cuttings:
This is my go-to method. It’s straightforward and generally yields excellent results.
- Select healthy stems: Look for stems that are actively growing but not flowering. They should be reasonably firm, not too woody, and have a few sets of leaves.
- Make the cut: About 2-4 inches down the stem, make a clean cut just below a leaf node (where the leaves attach to the stem).
- Prepare the cutting: Gently remove the lower leaves, leaving just 2-3 leaves at the top. This prevents them from rotting in the soil and helps the plant conserve energy for root formation.
- Apply rooting hormone (optional): Dip the cut end of the stem into rooting hormone. Tap off any excess.
- Plant in moist soil: Fill your small pots or trays with your well-draining potting mix. Make a small hole with your finger or a pencil.
- Insert the cutting: Place the prepared cutting into the hole, ensuring the nodes where you removed leaves are buried. Gently firm the soil around it.
- Water lightly: Give them a gentle watering.
2. Division:
This is perhaps the easiest method, especially for established clumps.
- Gently unearth the plant: Carefully dig up your Leptinella squalida, trying to preserve as much of the root system as possible.
- Assess the clump: You’ll see how the plant naturally spreads out.
- Separate sections: Using your hands or a clean knife, gently pull or cut apart sections of the plant. Each section should have a good amount of roots and some healthy foliage. Don’t be afraid to split dense clumps.
- Replant immediately: Pot up the divisions into fresh, well-draining soil. Water them in well.
The “Secret Sauce” (Pro Tips)
With a little extra care, you can really boost your success rate. These little tricks have served me well over the years:
- For stem cuttings, skip the water bath: While water propagation is great for some plants, I’ve found Leptinella squalida stem cuttings prefer to go straight into soil. If you do try water, make sure none of the leaves touch the water, as this can lead to rot. They need that moist-but-not-soggy environment from the get-go.
- Consider bottom heat: If you’re propagating in a cooler time or want to speed things up, placing your pots on a heat mat can significantly encourage root development. It Mimics the warmer soil temperatures of summer.
- Mist, don’t soak: Once your cuttings are planted, the key is to keep them in a humid environment. Lightly mist them with water a couple of times a day, or use a propagator. The goal is to keep the leaves turgid without waterlogging the soil, which invites fungal issues.
Aftercare & Troubleshooting
Once your cuttings have had a week or two, they should start to look perky.
- Check for roots: You can gently tug on a cutting; if there’s resistance, you’ve got roots! You can also look for new growth on the top.
- Gradual acclimatization: Once roots have formed and you see steady growth, gradually remove the plastic bag or propagator over a few days. This helps them adjust to normal humidity levels.
- Watering: Continue to water your new plants when the top inch of soil feels dry. Water thoroughly until water drains from the bottom.
- Troubleshooting: The most common issue you’ll face is rot. If you see a cutting turning black and mushy, it’s likely due to overwatering or poor drainage. Unfortunately, often these are lost. Ensure your mix is airy and don’t let them sit in water. If you see yellowing leaves but no other signs of rot, it might be a sign they need a bit more light, or perhaps they’re just adjusting.
A Encouraging Closing
Propagating Leptinella squalida is a delightful journey. Don’t get discouraged if a few don’t make it – that’s part of the learning curve for all of us! Be patient, enjoy the process of nurturing these tiny new plants, and soon you’ll have an abundance of these delightful Brass Buttons to decorate your garden or share with fellow plant lovers. Happy planting!
