How to Care for Potted Mums

As summer fades and autumn rolls in, it’s time to welcome one of the season’s most iconic flowers — the chrysanthemum, or as most of us call them, mums. These vibrant blooms are a staple in fall décor, adding bursts of color to porches, patios, and gardens. Whether you’re a seasoned green thumb or just starting out, caring for potted mums is simple with a few key tips.

Here’s how to keep your mums healthy, happy, and blooming beautifully all season long.

Choosing the Right Pot & Placement

Start with a container that drains well — think terra cotta, ceramic, or even the plastic nursery pot your mum came in. Good drainage is essential to prevent root rot.

If you’re repotting, use a high-quality potting mix from Feeds’n Needs that holds moisture but still drains well. Mums love sunlight, so place them where they’ll get at least 6 hours of direct sun daily. Want to extend their bloom time? Try a spot with partial shade to slow down bud opening.

Watering Wisely

Mums like consistent moisture, but soggy soil is a no-go. Water when the top inch of soil feels dry, and always aim for the base of the plant — not the leaves — to avoid fungal issues. A regular watering schedule will help your mums stay vibrant longer.

Deadheading for More Blooms

To keep your mums looking fresh and encourage new flowers, remove faded blooms as they appear. This redirects the plant’s energy into producing more blossoms instead of seed.

Fertilizing for Fall Success

If you’re growing mums from spring, start feeding them with a balanced fertilizer like 10-10-10. As buds begin to form, switch to one with higher phosphorus and potassium (like 5-10-5) to boost blooms and root strength.

• Start feeding after the last frost in spring
• Continue until late July
• Feed every 7–14 days
• Water deeply after fertilizing to avoid root burn

If you’re treating your mums as seasonal décor and plan to compost them after fall, you can skip the fertilizer.

Winterizing Your Mums

Want your mums to come back next year? Here’s how to give them a fighting chance:

• Wait until after the first hard frost
• Add 4 inches of mulch (straw or shredded hardwood) around the base
• Leave stems intact — prune in spring, not fall
• In early spring, remove mulch and trim away dead growth

Keep in mind: mums are hardy, but poor drainage or extreme cold can reduce their chances of surviving winter.

Conclusion

Caring for potted mums is a great way to celebrate the season and add a splash of color to your outdoor space. With the right pot, proper watering, and a little TLC, your mums will thrive well into autumn — and maybe even return next year.
