Introduction
As temperatures start to dip, you might be wondering, how cold can mums tolerate? These vibrant flowers are a fall favorite, but they need a little extra TLC when the weather gets chilly. In this article, I’ll walk you through essential care tips for mums as temperatures fall, focusing on watering, deadheading, mulching, and everything you need to know to protect your plants from frost.
Care Tips for Mums in Fall

Watering
When it comes to watering, consistency is key, but it can get tricky as temperatures drop. I usually recommend giving your mums a good drink, but be careful not to overdo it. Mums prefer moist soil, but soggy roots can lead to rot. Keeping the soil moderately moist allows your chrysanthemums to thrive without drowning them. For me, I like to check the top inch of soil. If it feels dry, it’s time to water.
Deadheading
Removing those faded flowers is not just about aesthetics; it encourages your mums to keep blooming! Since I love a garden full of color, I make it a point to deadhead regularly. This simple task can help you extend the bloom season of chrysanthemums. Plus, it gives your plant a fresh new look.
Mulching
You might not think about mulch in the fall, but here’s why it’s essential: it helps retain moisture and protects the roots. I usually apply a layer of mulch around my mums as soon as I see autumn setting in. It’s like giving them a cozy blanket for those chilly nights. Mulch is particularly important if you live in an area where the temperature can drop significantly.
Handling Frost Conditions

Frost Tolerance
Let’s get real—mums can handle light frost, but their blooms? Not so much. If you notice frost in the forecast, don’t panic! Covering your plants with a blanket or some burlap can offer a simple solution to protect them. As a rule of thumb, the ideal temperature for these plants is between 20°F and 50°F. If it gets any colder, that’s when you might want to bring your potted mums indoors.
Protection Strategies
When the frost is on the way, it’s time to bring out your protective gear! Covering plants during these chilly nights can save your blooms. For instance, I once had to rush out and cover my garden with sheets when I read about an unexpected frost. Trust me, it works! And if you have garden mums, consider cutting them back after the first frost to give them a healthy reboot for next spring.
Extending Bloom Life

Watering Practices
As the temperatures begin to drop, maintaining moisture becomes even more crucial. Here’s a tip: I like to set up a regular watering schedule. This helps ensure that my mums don’t go thirsty as they approach their dormancy period. Keeping the soil consistently moist, but not soggy, is essential for healthy blooms.
Fertilizing
Applying a balanced fertilizer during the growth season can work wonders. The right fertilizer helps provide the nutrients your chrysanthemums need, especially as they prepare for winter. I prefer using organic fertilizers that release slowly, giving my plants a stable nutrient supply.
Soil and Sunlight Requirements
Mums thrive in well-draining soil and love full sunlight. Without adequate light, you’ll find your plants struggling to bloom. If you’re unsure about your soil, consider doing a soil test. I love knowing that my garden is getting the best conditions possible. A well-draining mix keeps roots healthy and provides the perfect environment for your chrysanthemums.
Checking for Pests
Pests can be a significant threat, especially as the season changes. I recommend regularly inspecting your plants for any signs of trouble. Aphids, spider mites, and other pests can wreak havoc on your beautiful blooms. Using insecticidal soap is often my go-to solution; it’s effective and doesn’t harm beneficial insects. Being proactive with pest control means you can enjoy vibrant mums throughout the season.
