Coleus are not just gorgeous, they’re also super beginner-friendly when it comes to making more of them. So, grab your gardening gloves (or just your hands!), and let’s get started! We’ll guide you through every step of propagating coleus plants – either by using cuttings or planting seeds.
Now, when’s the best time to do this? Honestly, whenever you feel like it! You can snip cuttings from a healthy coleus anytime, especially if you’re keeping them cozy indoors. Some folks say Spring is ideal, but as long as your plant is getting good light, you’re good to go pretty much whenever. Just a little tip: always pinch off those flower stalks! Coleus put their energy into flowers which causes them to decline.
Cuttings: Clone Your Coleus!
This method is like magic – you take a snip of an existing plant and turn it into a whole new one! Here’s how:
What you’ll need:
- A healthy, happy coleus plant (the “mother” plant!)
- Clean scissors or pruning shears
- A glass of water or small pots with potting soil
- Optional: Rooting hormone
Here’s the step-by-step:
Choose a Stem: Find a nice, sturdy stem on your coleus that’s about 4-6 inches long. Make sure it’s got plenty of leaves, but no flowers (or just snip those off). I have to be honest, I sometimes use steps with flowers on them, I just cut those flowering blooms off.
Using a mature plant doesn’t harm it at all! It actually encourages it to branch out and become even bushier as it grows.
Cut the Stem: Using your super-clean scissors, make a cut just below a leaf node (that’s the little bump where a leaf grows out) on the stem. A clean cut is important, so your “mother” plant stays healthy.
Prepare the Cutting: Gently remove the leaves from the bottom 2 inches of the stem. This bare part is what will go in the water or soil. You can dip the cut end in rooting hormone for extra oomph, but it’s not a must.
Rooting in Water:
- Pop your prepared stem into a glass of water, making sure those bottom 2 inches are submerged.
- Place the glass in a warm, bright spot (but not in direct, scorching sunlight).
- Change the water every couple of days to keep it fresh and clean.
- In about two weeks, you should see little roots sprouting! Once they’re about an inch long, it’s time to plant your baby in its own pot of soil.
Rooting in Soil:
- You can also plant your healthy stem directly into a small pot (with drainage holes) filled with moist potting soil mix. Easy peasy!
- Poke a little hole in the soil with your finger or a pencil, gently pop the stem in, and pat the soil around it nice and snug.
- Keep the soil moist (but not soggy!) and put the pot in a warm, bright spot. You can even cover the pot with a plastic bag or a mini-greenhouse dome to create a humid little haven. I have these covers I love, and I use them to cover my geraniums.
You don’t need to put them on a heat mat.
Water regularly, as needed, and don’t let them dry out.
The stem will root in a few weeks, at which point it will start to show new growth.
I use these covers for cuttings that need the headroom, for seeds, I use a shorter dome or cover. Remove once you notice root formation. (if it is done in smaller pots or containers you will notice root emerging from the drainage holes)
Seeds: Start Small, Dream Big!
Growing coleus from seed is like a miniature miracle – watching a tiny seed sprout into a vibrant plant is so rewarding! Here’s how to make it happen:
What you’ll need:
- Coleus seeds
- Seed starting mix or potting soil
- A pot or seed tray
- Plastic wrap or a plastic dome
Here’s the step-by-step:
- Prepare the Seeds: Fill your pot or seed tray with moist seed starting mix or potting soil. Coleus seeds are TINY, so don’t bury them deep – they need light to sprout! I like to start mine in early Spring.
- Sow the Seeds: Gently sprinkle the seeds on top of the soil. You can give them a light pat with your finger, but don’t cover them completely.
- Maintain Moisture: Cover the pot or tray with plastic wrap or a plastic dome to keep the soil nice and humid. Pop it in a warm, brightly lit area (but away from direct sun).
- Watch Them Grow: Keep a close eye on your seeds, give a drink every day, and make sure the soil stays moist. In about 2-3 weeks, you should see tiny seedlings peeking through the soil. Yay! Once they arrive, remove the plastic wrap.
- Transplanting: Once your seedlings are a few inches tall and have a couple of sets of true leaves (the ones that look like real coleus leaves), they’re ready to be transplanted into larger pots or into your garden! If you have slugs watch out, they will eat your beautiful leaves!
Pro Tips for Coleus Success:
- Light: Coleus plants love bright, indirect light. Too much direct sun can make their colors fade (unless you have one specifically bred for full sun).
- Water: Whether you’re rooting cuttings or growing from seed, consistent moisture is key!
- Patience: Propagation takes time. Let your plants get their groove on, and you’ll be rewarded with a beautiful new coleus!
By following these simple steps, you’ll be propagating coleus like a pro, adding bursts of color to your home and garden!
Oh, and here’s a bonus tip: you can bring your coleus inside for the winter and enjoy them as houseplants! (Just bring them in before the first frost.)
Happy growing, friends!
