Can you root chrysanthemum cuttings in water? Yes. Chrysanthemum cuttings in water can root, because mums are propagated commercially from terminal stem cuttings. Tamil Nadu Agricultural University (TNAU) says terminal cuttings of 5–7 cm (about 2–3 inches (5.1–7.6 cm)) are taken from healthy stock plants, and roots typically form within a few weeks. Use soft tip cuttings, remove lower leaves, keep light moderate and change the water often.
Key takeaway: Garden mums (Chrysanthemum × morifolium) are short-day plants, so cuttings taken in long days stay vegetative and root more easily. Water rooting works, but cuttings rot if leaves sit in water or water goes stale. Many growers root in water, then pot up promptly once roots are an inch long.

What Are Chrysanthemum Cuttings?
Chrysanthemum cuttings are soft shoot tips taken from a healthy mum plant and rooted to make new plants identical to the parent. NC State Extension describes garden mums as herbaceous perennials in the daisy family, forming mounds 1–3 feet (30–91 cm) tall, with cutting listed as a recommended propagation method. Seeds do not come true, so cuttings keep the variety.
Commercial growers root cuttings in trays rather than water, but home growers often use jars. If you are new to rooting in water, see water propagation vs soil propagation for the pros and cons.
Why Root Chrysanthemum Cuttings in Water?
Rooting chrysanthemum cuttings in water is cheap and lets you watch roots form. It is a simple way to save a favorite potted mum from a florist or garden center, or to multiply a variety for next year. Water rooting also suits a hydroponic grower who will move rooted cuttings into net cups.
- True to type: cuttings copy the parent plant.
- Low cost: a jar and clean water are enough.
- Visible progress: you can check roots daily.
- Easy to scale: one stock plant gives many tips.
How Do You Root Chrysanthemum Cuttings in Water Step by Step?
To root chrysanthemum cuttings in water, take 2–3 inch (5–7 cm) non-flowering tips, strip the lower leaves and stand them in clean water in bright, indirect light. Change the water every two to three days. TNAU notes commercial rooting can be improved with rooting hormone, but home cuttings often root without it.
- Choose soft, non-flowering shoot tips from a healthy plant.
- Cut 2–3 inches (5–7 cm) long, just below a leaf node.
- Remove leaves from the lower half of the stem.
- Stand the cuttings in a jar of clean, room-temperature water.
- Keep them in bright, indirect light, not hot sun.
- Change the water every 2–3 days and remove any rotting cuttings.

How Long Do Chrysanthemum Cuttings Take to Root in Water?
Chrysanthemum cuttings usually root in a few weeks. Michigan State University says unrooted cuttings of many ornamental crops take 15 to 20 days to root under favorable conditions. Water rooting can be similar in warm rooms but slower in cool ones. See how long water propagation takes for the factors.
What Light Do Chrysanthemum Cuttings in Water Need?
Chrysanthemum cuttings need moderate, diffuse light while rooting, not strong direct sun. Michigan State University floriculture guidance says light levels for unrooted cuttings should start low and increase as roots form. Because mums are short-day plants, keep days long during rooting so cuttings stay vegetative.
| Stage | Light guidance | Source |
|---|---|---|
| Before roots | Low, diffuse light | Michigan State University |
| Roots emerging | Increase light gradually | Michigan State University |
| Day length | Long days keep cuttings vegetative | TNAU (short-day plant) |
| Flowering | Short days trigger buds | TNAU Agritech |
TNAU notes chrysanthemum is a short-day plant, so commercial growers time planting so flowering coincides with short days. Indoors, you control this with a timer.
Can Chrysanthemum Cuttings in Water Go Into Hydroponics?
Yes. Once chrysanthemum cuttings in water have roots about an inch long, move them into net cups with clay pebbles or into rockwool in an ebb and flow or drip system. Keep the stem base above the solution and give long days while plants grow, then short days if you want flowers.
| System | Fit for rooted mum cuttings | Note |
|---|---|---|
| Ebb and flow | Excellent | Roots dry between floods |
| Drip into coco | Excellent | Common for potted mums |
| DWC with air stone | Good | Keep the stem base dry |
| Plain water long term | Poor | No nutrients; rot risk |
What Problems Affect Chrysanthemum Cuttings in Water?
The main problems with chrysanthemum cuttings in water are stem rot, wilting and early flower buds. Rot starts when leaves sit in water or water gets stale. Wilting means too much light or heat before roots form. Buds on cuttings mean short days, so pinch them off and lengthen the light period.
- Black, mushy stem: recut above the rot and use fresh water.
- Wilting leaves: move to softer light; reduce leaf area.
- Buds on cuttings: pinch them and extend day length.
- No roots after 4 weeks: try fresher, softer tips.
When Is the Best Time to Take Chrysanthemum Cuttings?
The best time to take chrysanthemum cuttings is in spring and early summer, when plants produce soft, non-flowering shoots and days are long. NC State notes garden mums grow in spring and summer and flower in autumn. Cuttings from flowering autumn stems root poorly because the plant is focused on blooms rather than new growth.
If you buy a potted florist mum, cut it back after flowering and let it regrow. New shoots that appear later make far better cuttings than the original flowering stems.
FAQ About Chrysanthemum Cuttings in Water
Can you grow chrysanthemum cuttings in water from a florist bouquet?
Sometimes, if stems still have soft, non-flowering shoots. Old flowering stems root poorly.
How long are chrysanthemum cuttings in water before roots appear?
Usually a few weeks; Michigan State gives 15–20 days for many cutting crops.
Do mum cuttings need rooting hormone?
Not always. TNAU notes hormone is used commercially to improve rooting.
Why are my mum cuttings flowering?
Short days trigger buds. Give longer days while rooting.
Are chrysanthemums safe for pets?
NC State lists them as a problem for cats, dogs and horses.
