Pot Mums are a great choice for beginners because they're relatively low-maintenance and can thrive in a variety of conditions.
They're perfect for indoor spaces, as they can tolerate low light and infrequent watering.
To keep your Pot Mums happy, make sure the soil is moist but not waterlogged.
This means checking the soil daily and watering only when it feels dry to the touch.
General Information
The Pot Mum is a classic houseplant often brought as a gift at special occasions like Christmas, Easter, or Mothering Sunday.
It's originally a garden plant, known as Chrysanthemum, which blooms in late Summer through to Autumn and can grow up to 90cm / 3ft tall.
You can buy it as a smaller houseplant, treated with hormones and lighting tricks to restrict growth and cause out-of-season flowering.
This allows you to buy it all year round in a compact size.
Care Guide
To keep your pot mum flower thriving, it's essential to provide it with the right conditions. Good bright light is a must, so place it in a spot that gets plenty of sunlight or use grow lights if necessary.
Water your pot mum when the top 2-4 inches of soil feels dry to the touch. Check the soil moisture by sticking your finger into the soil. If it's dry, it's time to water.
The ideal temperature for your pot mum is between 18°C (64°F) and below. This will help the flowers last longer. If you keep it in a warmer location, the flowers might not last as long.
Fertilize your pot mum every month or so during spring and summer. You can use a slow-release fertilizer, which is a great care-free choice for container plants.
To keep your pot mum looking its best, remove the faded flowers. This will prevent them from going mouldy and encourage more blooms to grow.
Here's a quick watering schedule to keep in mind:
- Water once or twice a week in good light and warm locations.
- Water once a week in winter or if growing in lower light/cooler conditions.
Remember to repot your pot mum every 2 years to give it fresh soil and a larger pot if necessary. This will help it continue to thrive and produce beautiful blooms.
Watering and Humidity
Mums are thirsty plants and like to be moist, so it's essential to water them regularly. Watering mums is crucial to keep them looking great and prevent stress.
To check if the soil is damp, stick your finger into the top inch of soil, and if it feels dry, give your mum a nice slow soak. Watering at the base of the plant, closest to the roots, very slowly is also a good tip. Don't let the soil dry out to a point where the plants wilt, as they will revive well after watering.
Mums prefer moist soil, but not waterlogged soil, so be sure to check the soil daily and dump out any excess water if there's still water in the saucer the next day. If you notice the foliage of your mum starts to droop or wilt, immediately give your plant a big drink of water.
Watering
Mums are thirsty plants and like to be moist, so it's essential to water them regularly.
Water your mums about 1 inch of water per week, and make sure the soil is damp at all times.
If you notice the soil feels dry, give your mum a drink, and always water from the bottom of the plant directly into the soil to avoid getting the leaves and flowers wet.
Mums in plastic containers tend to dry out quickly, so check the soil daily by sticking your finger into the soil to your second knuckle, and give them a good soaking if it feels dry.
Don't let the soil dry out to a point where the plants wilt, as this can cause the flower buds to not last as long or look as bright.
Watering your mums regularly will help them thrive, and if you notice the foliage looking limp or starting to turn brown, water more often to keep them healthy.
Humidity
Humidity is key when it comes to keeping your plant happy. If you're only keeping it temporarily, humidity isn't a concern.
You can place it in a dry area without worrying, but if you're planning on keeping it around for a while, avoid low humidity spots.
Any decent all-purpose fertilizer once a month will do.
Chrysanthemum Specifics
Pot Mums are primarily outdoor plants, making it challenging to keep them as permanent house guests.
To avoid disappointment, buy plants with many buds showing color, as those with closed buds are less likely to open.
Chrysanthemums are mildly toxic and an irritant to cats and dogs, so keep them out of reach.
They thrive in bright light, full sun, or a combination of both, which helps keep the flowers vibrant and new buds forming.
To care for your Chrysanthemum, water it once or twice a week in good light and warm locations, and once a week in Winter or lower light/cooler conditions.
Here are some key temperature guidelines:
Keep the soil moist throughout growth and bloom season, and fertilize regularly for the best display.
Chrysanthemum Problems
Chrysanthemum Problems are more common than you'd think, and understanding the causes can help you avoid disappointment.
Not all buds on your Pot Mum will open, and that's quite normal. To minimize this, aim to buy plants with buds showing colour, as these are more likely to open.
Extensive underwatering, low humidity, and too much sun can cause crispy leaves on your Chrysanthemum. This might not happen right away, as these plants are tough and can hide their problems.
Grey mould on stems, flowers, or leaves is a classic symptom of Botrytis, triggered by cold and/or wet conditions. Remove infected parts and correct the growing conditions to prevent further damage.
Remember, Chrysanthemum is primarily an outdoor plant, making it challenging to keep as a permanent house guest.

Caring for Chrysanthemums
Chrysanthemums need bright light to keep their flowers vibrant and produce new buds. Some direct sunlight is okay too.
If you're keeping your Chrysanthemum indoors, it's best to place it in a cooler room with temperatures 18°C (64°F) or below, as this will help the flowers last longer.
Moderate watering is key, with most plants needing water once or twice a week in good light and warm locations. However, in Winter or lower light/cooler conditions, you may only need to water once a week.

To encourage more blooms, remove faded flowers as soon as they fade, and trim the foliage to maintain the desired size and shape.
Here's a quick rundown of the basic care needs for Chrysanthemums:
- Keep soil moist throughout growth and bloom season.
- Fertilize regularly for best display.
- Keep away from drafts.
- Remove faded flowers.
It's also essential to repot your Chrysanthemum every 2 years in a container slightly larger than the diameter of the roots, and to use a good quality, commercial potting soil that's sterile and pest-free.
Container and Soil
You can keep your pot mum in its original black plastic container if it's not too pot-bound, but putting it in a larger, more decorative container is much more attractive.
Choose a container that's larger than the pot your mum came in, as this will help ensure a healthy start for your fall perennial.
Mums thrive in well-drained soil, so if your yard's soil doesn't drain properly, add compost and mix it in about 8 to 12 inches deep for best performance.
Don't forget to weed regularly around your mums, as their shallow roots can't compete with weeds for water and nutrients.
How to Shop
To shop for a great container and soil combination, look for a pot with good drainage holes to prevent waterlogged soil. This is crucial for the health of your plants.
Choose a pot that is the right size for the plant you're buying, as this will help prevent the soil from becoming too dry or too wet.
Pick out plants with tight flower buds and lots of new growth, like mums, for a longer-lasting and more vibrant display.
Choose the Right Container
You can keep mums in their original black plastic containers if they're not too pot-bound, but putting them in a more decorative container is a great way to enjoy their beauty.
Choose a container that's larger than the pot they came in, as this will help ensure a healthy start for your mums.
Planting mums in a container that's too small can lead to poor growth and root bound conditions.
You can plant mums about 1 inch deeper than they were in the nursery pot, handling the roots with extra care as you spread them.
A larger container will also give you room to add some extra soil and nutrients to help your mums thrive.
By following these simple tips, you can create a beautiful and thriving mum display that will add some much-needed color to your outdoor space.
Soil
Mums thrive in well-drained soil, so if your yard's soil doesn't drain properly, add compost and mix it into the soil about 8 to 12 inches deep for best performance.
If your soil has poor drainage, grow mums in raised beds filled with a well-draining garden soil mix. Don't forget to weed regularly around your mums, as their shallow roots can't compete with weeds for water and nutrients.
Mums don't like to stand in water, so make sure any pot you put them in has good drainage, or use a creative solution like lining the bottom with small plastic pots or other materials to allow excess water to drain.
Planting and Care
To keep your pot mum flower happy and thriving, make sure it's in a spot with bright light or full sun. This will help the flowers stay vibrant and the plant produce new buds.
When it comes to watering, aim to keep the soil consistently moist but well-drained. Check the soil moisture with your finger, and if the top 2-4 inches of soil is dry, or the plants are wilted, it's time to water. Water the entire soil area until water runs out the base of the pot.
To fertilize your pot mum, use a good quality, commercial potting soil that's already mixed with a mild starter fertilizer. You can also apply slow-release fertilizers, which are a care-free choice for container plants.
Here are some key care tips to keep in mind:
- Remove faded flowers to keep the plant looking tidy and encourage more blooms.
- Repot every 2 years in the same container or in a slightly larger one.
- Trim the foliage to maintain the desired size and shape.
How to Plant
To plant mums, start by choosing a container that's larger than the pot they came in, as this will help ensure a healthy start for these fall perennials.
Plant the mums in the container about 1 inch deeper than they were in the nursery pot, handling the roots with extra care as you spread them.
Removing from Original Container
Removing the mum from its original container can be a bit tricky, but don't worry, I've got you covered. Gently squeeze the sides of the pot to loosen the soil and remove the mum.
Resist the urge to remove a mum by pulling it out by the foliage, as mums have brittle foliage that can break off easily.
To safely remove the mum, gently turn the pot over and slide the mum out. This is the best way to avoid damaging the plant.
If the mum is badly rootbound, soak the whole plastic pot in water until it loosens. This will make it much easier to remove the mum.
Plant in a Sunny Spot
Planting your mums in a sunny spot is key to their happiness and health. Mums love direct sunlight, so aim for at least six hours of sunlight per day if you're planting them outside.
Bright light or full sun is a must for vibrant flowers and new buds. Some direct sunlight will be accepted too. If you're planting indoors, choose a sunny place to keep them happy and healthy.
A different take: House Plants That Grow without Sunlight

If you're planting mums indoors, don't put them out too early in the season when summer is still in full swing. In hot weather, plants likely won't survive long.
Here are some tips for finding the perfect sunny spot for your mums:
- Avoid planting in areas with drafts, which can cause the flowers to wilt.
- Choose a spot with temperatures 18°C (64°F) and below for longer-lasting flowers.
By following these simple tips, you'll be well on your way to growing happy and healthy mums that will bloom from September until frost.
Growth and Pruning
Pruning is a crucial step in promoting healthy growth in pot mum flowers.
Cutting back the buds on your pot mum plant will encourage it to branch out and become fuller, preventing it from becoming leggy.
By pruning, you'll also give your plant the chance to produce more buds and flowers for fall blooming.
Pruning can be a bit painful, especially when you have to cut off those tiny buds, but it's essential for your plant's well-being.
Cut the flower buds completely off, making sure they're four to six inches from the ground, ideally around the 4th of July.
This will help your pot mum plant thrive and reward you with a beautiful display of flowers in the fall.

Repotting and Winterizing
Repotting your pot mum flower right after you buy it is one of the best things you can do. It's like giving your plant a fresh start in a new home with fresh potting mix.
Repotting helps to break up the compacted root ball that forms when mums sit in nursery containers. This sets your plant up for success and helps it grow strong.
If you live in a cold climate or have poor drainage, your pot mum flower may not survive the winter. But if it does, you'll see new growth developing around the base of the plant in early spring.
Winterizing
Winterizing is an essential step in preparing your garden mums for the cold months ahead. Mulching helps a plant to stay healthy, so add about two inches of mulch around your mums.
Mums have short root systems and need protection from winter conditions like hard frosts and dryness. Mulching is a great way to provide this protection.
If you live in a very cold climate, your mums may not survive the winter if drainage is poor. This is something to keep in mind when preparing your garden for the winter.
You can mulch up to 4 inches with straw or shredded hardwood around the plants. This will help to insulate the roots and keep them from freezing.
Don't pinch off dead blooms just yet - wait until spring when new growth starts to peek out of the soil. This will give your mums the best chance of surviving the winter.
Here's a quick rundown of what to do for winterizing:
- Prepare mums for winter after the first hard frost.
- Mulch up to 4 inches with straw or shredded hardwood around the plants.
- Pinch off dead blooms, but leave branches intact.
- Wait to prune old stems until spring.
Repotting
Repotting is a great way to give your plants a boost. Repotting your florist mums right after you buy them is one of the best things you can do.
Most mums in containers will have very compacted root balls after sitting in nursery containers. This can hinder growth and make it harder for the plant to absorb water and nutrients.
Gently breaking up the root ball and giving the mum a new home in fresh potting mix will set your plant up for success. This will give the roots room to grow and help the plant thrive.
By repotting your mums, you'll be able to give them the care they need to survive the winter months.
Tips for Looking Great
Consider moving your potted mums to a more shady spot temporarily if the weather forecast shows lots of sun and the temps moving to the upper 70s.
Repotting your mums into a larger pot with fresh potting mix can make a big difference in their longevity. I used to never repot the mums I purchased for my outdoor fall displays, until a few years ago, and I was surprised by the results.
Adding some organic matter from your compost pile into the bottom of the new pot will also help your mum last longer. Other than adding a little compost when you repot your mums, it is not necessary to fertilize them.
Potted fall mums can benefit from being protected from hot afternoon sun, especially if you live in warmer climates. Yes, potted fall mums are considered full sun plants (6+ hours of sun per day) and need plenty of sun.
