How to Deadhead Mums for Beautiful Fall Blooms

September 20, 2026

 

 

Deadheading mums is a straightforward process. Here’s how to do it:

Look for flowers that have started to wilt or turn brown. These are the blooms you’ll want to remove.

 

If the petals are falling off and you see a small seed head forming in the center, it’s time to deadhead.

Use clean, sharp pruning shears or scissors to make the cuts.

Follow the stem of the spent bloom down to the first set of healthy leaves and snip just above them. Cut the stem at a 45-degree angle.

This encourages new growth to emerge from that point.

If you have several spent flowers on one stem, cut back to the nearest branching point where new buds or blooms are developing.

 

Be cautious not to cut any unopened buds, as these will turn into future blooms.

You should start deadheading your mums as soon as you notice the first blooms starting to fade. This usually happens a few weeks into the flowering season.

Keep an eye on your plants throughout the season, from late summer to mid-fall, and snip off any flowers that look past their prime.

As the weather cools down and you see fewer new buds forming, you can gradually slow down on deadheading and allow the plant to prepare for winter.

Once you’ve finished deadheading, give your mums a good watering to help them bounce back. This will support the plant as it redirects its energy into producing more blooms.

For an extra boost, you can apply a balanced, water-soluble fertilizer every 2-3 weeks throughout the growing season. This will help replenish nutrients and encourage even more flowering.

Also, mulching around the base of your mums with organic material like compost or wood chips will help retain moisture and keep the roots cool.

Keep an eye out for any yellow or diseased leaves, and remove them promptly to promote healthy growth and prevent the spread of disease.

Deadheading is a quick and easy way to keep your mums looking their best. With just a few snips here and there, you’ll encourage more blooms, extend the flowering season, and keep your garden neat and vibrant all fall long.

Whether you’re a seasoned gardener or just getting started, this simple technique is a must for anyone growing mums. So grab your shears, and get ready to enjoy an extended display of beautiful fall colors!
