As the seasons change and fall arrives, many of us wonder how to care for our beloved mum plants during this time. Mums are one of the most popular fall flowers, but they require some special attention as the temperatures drop and daylight hours shorten. Neglecting your mums in the fall can lead to pest and disease problems, nutrient deficiencies, and even death. But don’t worry, with a few simple tips and techniques, you can keep your mum plants thriving well into winter. In this article, we’ll cover everything from cleaning up and cutting back to mulching, dividing, overwintering, and propagating your mums through cuttings and division. We’ll also share expert advice on how to protect your mum plants from common fall problems.
Preparing Your Mums for Winter
Now that the blooming season has come to a close, it’s time to prepare your mums for winter by taking steps to protect them from frost and harsh weather conditions. This involves several important tasks.
Cleaning Up and Cutting Back
As the blooming season comes to an end, it’s essential to give your mum plants some TLC to ensure they remain healthy and thrive come springtime. One crucial step is cleaning up dead or dying flowers, stems, and leaves from the plant. Removing these spent blooms will prevent the spread of disease and encourage new growth.
Cut back the plant by about one-third to one-half to promote vigorous growth in the spring. This process, known as “topping,” helps control the size of the plant and encourages it to focus its energy on producing new roots and stems rather than leafy growth. By doing so, you’ll be rewarded with more robust and resilient plants that will bounce back stronger come next growing season.
Don’t forget to also clean up any debris around the base of the plant, including dead leaves and spent mulch. This will help prevent pests and diseases from taking hold over the winter months. With these simple steps, your mum plants will be well-prepared for a successful rebirth in the spring.
Mulching and Dividing
As the temperatures drop and winter approaches, it’s essential to take steps to protect your mum plants from harsh cold snaps. One of the most effective ways to do this is by mulching around the base of the plants. Mulch serves as a barrier between the soil and extreme temperature fluctuations, helping to retain moisture and regulate soil temperature.
Apply a 2-3 inch layer of organic mulch such as wood chips or bark around the base of your mum plants. This will help insulate the roots from freezing temperatures and reduce water loss through evaporation. Make sure to leave a small gap around the plant’s crown to allow for air circulation and prevent moisture buildup.
If your mums have become overcrowded, consider dividing them in the fall to encourage new growth. Divide established clumps into smaller sections, making sure each section has at least one growing eye (the white bud from which new stems emerge). Replant the divided sections in a well-draining location with plenty of sunlight, and water thoroughly after planting. By mulching and dividing your mums, you’ll be setting them up for success come springtime.
Choosing the Right Location for Overwintering
When it comes to overwintering your mum plants, selecting a suitable location is crucial to ensure their survival through the cold months. Find out where to place them for maximum protection and success.
Selecting a Protected Area
When selecting a protected area for overwintering mum plants, it’s essential to choose a location that shields them from harsh winds, frost, and extreme temperatures. This will help prevent damage and ensure they survive the winter months.
Consider using a cold frame as a protective barrier. These structures allow natural light in while keeping frost at bay, creating an ideal environment for overwintering mum plants. Alternatively, you can also store your mums in an unheated garage or shed, making sure to provide adequate ventilation to prevent moisture buildup.
Another option is to plant them under the canopy of an evergreen tree, where they’ll receive protection from wind and frost while still benefiting from natural light. If possible, try to choose a location that receives morning sun and afternoon shade, as this will help regulate temperatures and prevent scorching.
When selecting a protected area, keep in mind that mum plants prefer temperatures between 35°F and 45°F (2°C and 7°C) during the winter months. Make sure your chosen location provides a stable temperature range to ensure their survival until spring.
Preparing the Site
Now that you’ve selected the perfect spot for overwintering your mums, it’s time to prepare the site. This is a crucial step to ensure your plants thrive during the cold winter months.
Begin by removing any debris or weeds from the area. You can use a garden fork or rake to gently loosen and remove unwanted growth. This will give you a clean slate to work with and prevent any competition for water and nutrients.
Next, till the soil to a depth of about 8-10 inches. This will help break up any compacted dirt and allow roots to grow freely. You can use a garden tiller or simply turn over the soil by hand if you don’t have access to one.
To create a suitable environment for your mums, apply a layer of mulch or compost around 2-3 inches thick. This will help retain moisture, suppress weeds, and regulate soil temperature. Organic options like wood chips or straw work well, but be sure to avoid applying too much at once as this can cause an overabundance of nutrients.
By following these simple steps, you’ll have a site that’s ready for your mums to settle in for the winter months ahead.
Overwintering Techniques for Mum Plants
To successfully bring your mum plants through another winter, you’ll need to employ some clever overwintering techniques that will keep them healthy and thriving until spring. Here are a few methods to try.
Bringing Indoors
When bringing your mum plants indoors for the winter months, it’s essential to choose a location that provides bright, indirect light but is not exposed to direct sunlight. A south-facing window with sheer curtains or blinds can be an ideal spot, as long as you’re mindful of the intensity of the light.
To maintain healthy and thriving plants, keep them in a room with consistent temperatures between 60°F to 70°F (15°C to 21°C). Avoid placing your mums near heating vents or radiators, which can cause stress to the plant. Consistent humidity levels are also crucial; you can achieve this by placing the pot on a tray filled with water and pebbles.
Watering is another critical aspect of overwintering mum plants indoors. Water sparingly, as the reduced light conditions slow down the plant’s growth rate. Check the soil moisture by sticking your finger into the soil up to the first knuckle; if it feels dry, it’s time for a gentle watering. Reduce watering even further during periods of prolonged cold weather or when the room is unheated.
Moving Outside
As fall comes to a close and the weather starts warming up again, it’s time to prepare your overwintered mum plants for another growing season. When moving them outside, it’s essential to acclimate them gradually to outdoor conditions to prevent shock.
Start by bringing them out of their wintering spot in late March or early April, when daytime temperatures are consistently above 50°F (10°C). Place the pots near a south-facing wall or under a shade tree to provide protection from intense sunlight. Begin the acclimation process by spending the first few hours outdoors in a sheltered area.
Check the plants for any signs of pests or diseases before repotting them into larger containers with fresh potting mix. This is also an excellent opportunity to prune back leggy growth and shape your mums for the upcoming season. Once they’re settled, you can gradually increase their exposure to direct sunlight over the next few days.
Monitor their response closely, and if you notice any signs of stress or decline, consider providing additional care, such as fertilization or protection from extreme weather conditions.
Propagating Mums Through Cuttings and Division
If you’re looking to share your mum plants with friends or start new ones for next year, propagating through cuttings and division is a simple and effective way to do so. Let’s explore these methods together!
Taking Cuttings
Taking cuttings from established mums is a great way to multiply these beautiful plants and enjoy their blooms for years to come. To start, select healthy stems with at least two sets of leaves, ideally from the current year’s growth. Cut these stems just above a node using a sharp, clean knife or pruning tool.
Next, prepare your cuttings by removing lower leaves that would be submerged in water or propagation medium. This helps prevent rot and promotes rooting. You can take multiple cuttings from each stem, but make sure to space them evenly apart to prevent overcrowding.
To root your cuttings, you have two options: water or a propagation medium like potting soil or a specialized mix. Place the cut ends in a glass of water or directly into the propagation medium, making sure the node is buried. Keep the cutting in a bright, warm location with consistent moisture levels, and roots should develop within 1-2 weeks.
Monitor your cuttings closely for signs of rooting, such as new growth or resistance when gently tugged. Once established, you can transfer them into individual pots filled with well-draining soil and enjoy their blooms next fall.
Dividing Established Plants
As your mum plants have reached maturity, it’s essential to divide them to encourage new growth and prevent overcrowding. This process, called division, is a simple yet effective way to promote healthy plant development. By dividing established mums, you’ll be able to create multiple new plants that can be replanted in other areas of your garden or shared with friends.
Timing is crucial when it comes to dividing mature mum plants. The ideal time for division is during the spring or fall when the plants are dormant. This allows the cut sections to establish themselves before new growth begins. If you divide in the middle of the growing season, the newly divided sections may struggle to thrive due to increased water and nutrient demands.
To divide your mums correctly, choose a section with at least two sets of leaves and some stem growth. Cut back the top growth by about half to encourage new growth from the base. Gently dig up the plant, separate the roots, and replant each section in well-draining soil. Water thoroughly and provide regular care to ensure successful establishment.
Common Problems and Solutions for Overwintered Mums
As you’re learning to care for your overwintered mums, you might encounter some common issues that can be easily addressed. Let’s tackle these problems together and find simple solutions.
Pests and Diseases
As you care for your overwintered mums through the fall season, it’s essential to keep an eye out for common pests and diseases that can affect these beautiful plants. Aphids and whiteflies are two of the most prevalent pests that can infest mum plants, causing curled or distorted leaves, and a sticky substance on the undersides of the leaves. To identify these issues, look for tiny, soft-bodied insects or flying insects around your plants.
To control aphid and whitefly populations, try using neem oil or insecticidal soap as a foliar spray. These organic controls can be applied according to the product’s instructions, typically every 7-10 days. If the infestation is severe, you may need to use a systemic insecticide, but these should be used with caution and only as a last resort.
Root rot is another common issue that can occur in overwintered mums. This disease is caused by excessive moisture and poor drainage, leading to fungal growth on the roots. To prevent root rot, ensure your mum plants are not waterlogged and provide good air circulation around them. If you notice yellowing leaves or a soft, mushy stem, it may be too late to save the plant. Remove any affected areas immediately to prevent further spread of the disease.
Nutrient Deficiencies
As the weather cools down and daylight hours shorten, overwintered mum plants may start to show signs of nutrient deficiencies. One common issue is yellowing leaves, which can be caused by a lack of iron or magnesium in the soil. To diagnose this problem, inspect the leaves for any visual symptoms such as interveinal chlorosis (yellowing between the veins) or stunted growth.
If you suspect that your mum plant is suffering from nutrient deficiencies, it’s essential to address the issue promptly through fertilization and soil amendments. A balanced fertilizer with a ratio of 10-10-10 (nitrogen-phosphorus-potassium) can help supplement any lacking nutrients. You can also consider adding compost or well-rotted manure to improve soil fertility.
Some common signs of nutrient deficiencies in mum plants include:
* Reduced flowering
* Stunted growth or slow expansion of the plant
* Yellowing leaves with brown tips
* Wilting or droopy foliage
To prevent these issues, make sure to fertilize your overwintered mums regularly, ideally once a month during the fall and early winter months.
Tips for Overwintering Success
To help your mums thrive through the cold winter months, follow these essential tips for overwintering success and enjoy vibrant blooms come spring.
Monitoring Weather Conditions

Check the weather app or website for temperature fluctuations, especially during the first few weeks of winter. If a cold snap is predicted, bring potted mums under cover or move them to a protected area like a garage or shed. If you’re overwintering in the ground, consider applying a thick layer of mulch or straw around the base of the plant to insulate it from frost.
Keep an eye on wind forecasts as well, as strong gusts can cause damage to even the sturdiest mum stems. If possible, bring potted mums under cover during periods of high winds. By staying vigilant and taking proactive measures, you’ll be able to enjoy your beautiful mums come springtime.
Maintenance Tasks
As you bring your mum plants inside for overwintering, it’s essential to maintain them properly to keep them healthy and thriving. One of the most critical maintenance tasks is watering. Since mums prefer well-draining soil, reduce watering to once a week during the fall and winter months. Make sure the soil isn’t waterlogged, as this can lead to root rot.
Pruning is another vital task to promote healthy growth and prevent disease. Remove any dead or dying blooms to encourage new growth, and cut back the stems by about one-third to half their original height. This will help your mum plant conserve energy and redirect its resources towards producing new flowers in the spring.
Repotting may also be necessary if you’re planning to keep your mum plant for an extended period. Choose a pot that’s only slightly larger than the previous one, and use a well-draining potting mix specifically designed for indoor plants. This will help prevent waterlogged soil and root rot.
