Propagation
How to grow mums from cuttings lets you multiply your favorite varieties for free. đż I've propagated dozens of chrysanthemums this way, and the secret lies in timing and clean cutsâno fancy equipment needed. The best part? You can start anytime the parent plant is healthy, not just during a specific season.
You'll need sharp scissors, rooting hormone (optional), small pots, and a bright window or grow light. The process takes about 4-6 weeks from cutting to rooted plant, and most cuttings succeed if you avoid overwatering or letting them dry out.
I've even rooted cuttings in plain water, though soil works better for mums.
By the end of summer, you'll have bushy new plants ready to transplant. These won't bloom their first year, but they'll establish strong roots and give you double the flowers next season. The fragrance alone makes it worth the effortâimagine rows of mums that smell like autumn.
Works for both garden mums and container varieties, and you can take cuttings in spring or early summer. The key is patienceâthese plants reward careful propagation with years of reliable blooms. Ready to multiply your favorites?

What you need
- ● Healthy mum plant: Choose a thriving chrysanthemum with woody stems (not too soft or floppy). Look for one with multiple stems for more cuttings!
- ● Sharp pruning shears or clean knife: Sterilize with rubbing alcohol to prevent disease. A bypass pruner works best for clean cuts.
- ○ Rooting hormone (optional but recommended): A powder or gel like Rootone or Clonex to boost success rates.
- ● Well-draining potting mix: Use a 50/50 blend of perlite or sand and peat moss or coconut coir. Avoid garden soilâitâs too dense!
- ● Small pots or trays: 3â4 inch pots (for individual cuttings) or a seedling tray with drainage holes. Plastic or biodegradable pots work well.
- ● Clear plastic bag or humidity dome: A ziplock bag or propagation lid to retain moisture and create a mini greenhouse.
- ● Misting bottle: A spray bottle with water to keep cuttings hydrated without overwatering.
- ● Labeling tags: Small plant markers to track varieties (e.g., "Pink Quill" or "Yellow Gem").
- ● Grow lights or sunny windowsill: A LED grow bulb or south-facing window (6+ hours of light/day) speeds up rooting.
- ○ Heating mat (optional): A seedling heat mat (70â75°F) can accelerate root growth in cooler climates.
- ● Fertilizer (after rooting): A diluted liquid fertilizer (like fish emulsion or 20-20-20) to nourish new growth.
Step-by-step instructions for growing mums from cuttings
Here's the foolproof method I use to multiply my mumsâno fancy tools, just sharp scissors and patience.
đą Step 1: Select and Prepare Healthy Cuttings
Choose non-flowering stems from your healthiest mum plants in early summer. Look for 4-6 inch sections with 2-3 sets of leavesâthese will root best. Snip just below a leaf node with clean, sharp scissors to avoid crushing stems. I always sterilize my tools with rubbing alcohol first to prevent disease.
Remove the lower leaves, leaving only the top 2-3 leaves. This reduces moisture loss and prevents rot. Dip the cut end in rooting hormone powderâit triples your success rate. If you don't have hormone, a sharp pencil dipped in honey works in a pinch (the sugar encourages root growth).
đ§ Step 2: Root in Water or Moist Medium
Place the cuttings in room-temperature water or a mix of 50% perlite and 50% peat moss. For water propagation, use a clear glass so you can watch roots developâit's oddly satisfying. Change the water every 2-3 days to prevent bacterial growth. Roots should appear in 2-4 weeks.
If using soil, keep it consistently moist but never soggy. Mist the leaves lightly daily to maintain humidity. I cover my soil cuttings with a plastic bag secured with a rubber bandâthis creates a greenhouse effect. Watch for condensation on the bag; that's your sign the humidity is perfect. Roots will form when you see tiny white nubs at the stem base.
âď¸ Step 3: Transition to Soil and Encourage Growth
Once roots reach 1-2 inches long, transplant into 4-inch pots with well-draining potting mix. Gently firm the soil around the stem to eliminate air pockets. Place the pots in bright, indirect light for the first weekâdirect sun can scorch tender new growth.
Water when the top inch of soil feels dry. You'll know you're doing it right when the leaves stay vibrant and the stems feel sturdy when touched. After 2 weeks, gradually introduce more sunlight. By late summer, your cuttings should be ready to transplant outdoors or into larger containers.
âď¸ Step 4: Maintain and Overwinter for Next Year
Pinch back the tips of your new mums when they reach 6 inches tall to encourage bushier growth. This is where they start looking like the mums you know and love. Feed with a balanced 10-10-10 fertilizer every 4-6 weeks during the growing season to keep them blooming.
In fall, move potted mums to a sheltered spot before frost. They'll go dormant but stay alive. In winter, keep them in a cool (35-45°F) garage or basement. Resume care in spring when you see new growth. This is how I've kept the same mum varieties for yearsâno buying new plants needed!
Tips & tricks for perfect mum propagation
Real talk: Propagating mums from cuttings is easier than you thinkâonce you know these game-changing details.
Timing is Everything: Early summer is your golden window for cuttings, but don't wait past July. The plants need time to establish roots before fall's cooler weather sets in. I've found that cuttings taken in late June give the best resultsâthey're still vigorous but not yet stressed by heat. The 2-3 sets of leaves you select should be fully developed but not yet flowering, as blooms drain energy from root development.
Rooting Hormone Hack: While rooting hormone powder triples your success rate, I've had great results with the honey trick when I'm in a pinch. Just dip the cut end in a mixture of equal parts honey and waterâthis creates a natural sugar solution that encourages root growth. The key is to keep the cuttings in a warm spot (around 70°F) after dipping, as warmth speeds up the rooting process. For water propagation, change the water every 2-3 days to prevent bacterial growth, which can turn your water cloudy and stinky within days.
Humidity Control: That plastic bag you use to create a greenhouse effect? Don't let it stay sealed too longâopen it daily for 10-15 minutes to prevent mold growth. You'll know you've got the right humidity when you see condensation on the bag's interior. Too much humidity leads to rot; too little and your cuttings will dry out. I like to prop the bag open slightly with a toothpick if my kitchen tends to stay humid, which keeps airflow just right.
Light Transition Strategy: When moving your rooted cuttings to soil, remember that bright indirect light for the first week is crucial. Direct sun can scorch those tender new leaves, and you'll know you're doing it right when the leaves stay vibrant and the stems feel sturdy when touched. After those 2 weeks, you can gradually introduce more sunlightâthis slow transition prevents shock. I've seen cuttings that got too much sun too soon turn crispy at the edges, which is a heartbreaking mistake to make after all that hard work.

Frequently asked questions
Got questions about growing mums from cuttings? Youâre not alone! Here are answers to the most common queries to help you propagate like a pro.
Can I take mums cuttings at any time of year?
Nope! The best time is late spring to early summer, when mums are actively growing. Avoid winter or dormant seasonsâcuttings wonât root easily. Aim for warm, humid conditions (60â75°F) for success.
How long does it take for mums cuttings to root?
Patience is key! Most cuttings root in 4â8 weeks, depending on humidity and warmth. Check for new growth or slight resistance when tugging gentlyâsigns roots are forming. Keep them moist but not soggy.
Why are my mums cuttings turning yellow or mushy?
Overwatering or poor drainage is usually the culprit. Ensure pots have drainage holes and water only when the top inch of soil feels dry. Yellow leaves? Trim them off to redirect energy to root growth.
Can I use store-bought mums for cuttings?
Yes, but choose healthy plants with no signs of disease. Avoid heavily sprayed or treated mumsâthe chemicals can hinder rooting. Opt for organic or homegrown varieties for best results.
Do mums cuttings need special light?
Bright, indirect light is idealâthink 4â6 hours daily. Avoid harsh sun, which can scorch tender cuttings. A sunny windowsill or grow light works perfectly.
What if my cuttings rot before rooting?
Donât panic! Rot is often from overwatering or poor airflow. Adjust care by reducing water, improving drainage, and increasing airflow with a small fan. Start fresh with new, healthy cuttings if needed.
