If you want a spectacular burst of fall color, learning how to care for mums in pots is your key to success. These cheerful flowers, often called chrysanthemums, are perfect for porches and patios, and with the right approach, they can last for weeks or even return next year.
Potted mums are different from the ones planted in the ground. They need a bit more attention because their roots are confined. But don’t worry, it’s not complicated. This guide will walk you through every step, from picking the right plant to helping it survive the winter.
How to Care for Mums in Pots
This main section covers the core principles. Think of it as the foundation for keeping your potted mums healthy and vibrant all season long.
Choosing the Right Mum and Pot
Success starts at the garden center. Look for plants with more buds than open flowers. This means you’ll get a longer display as those buds open over time. Avoid plants that are completely wilted or have yellowing leaves.
The pot is just as important. Your mum will need excellent drainage to prevent root rot.
- Always choose a pot with drainage holes in the bottom.
- It should be at least 2-3 inches wider than the nursery pot it came in.
- Materials like ceramic, terracotta, or sturdy plastic all work well.
The Perfect Soil and Planting
Never use garden soil in a container. It’s too dense and will suffocate the roots. Instead, use a high-quality, lightweight potting mix. A mix labeled for containers is ideal because it drains well but still holds some moisture.
When you’re ready to plant, gently loosen the roots if they are tightly wound. Fill your pot partway with soil, place the mum in, and fill around it. The top of the root ball should be just below the pot’s rim. Water it thoroughly right after planting to settle the soil.
Sunlight and Location
Mums love the sun. For the best bloom and sturdiest growth, they need a minimum of 4-6 hours of direct sunlight each day. A bright, sunny spot is perfect.
If they don’t get enough light, they will become leggy and produce fewer flowers. You can rotate the pot every few days so all sides get even sun, leading to a more symmetrical plant. Also, try to place them somewhere sheltered from strong winds, which can damage the stems.
Watering Your Potted Mums Correctly
This is where many people go wrong. Mums like consistent moisture but hate soggy feet. The goal is to keep the soil evenly moist, not sopping wet.
- Check the soil daily by sticking your finger an inch deep.
- If it feels dry, it’s time to water.
- Water slowly at the base of the plant until you see it run out the drainage holes.
- Never let the pot sit in a saucer full of water.
In the heat of early fall, you might need to water every day. As temperatures cool, you’ll water less frequently.
Feeding for Fantastic Flowers
Potting soil doesn’t have many nutrients, so you need to supplement. To support all those blooms, use a balanced, water-soluble fertilizer.
A good routine is to fertilize every 2-3 weeks while the plant is actively growing and budding. You can use a general-purpose plant food. Stop fertilizing once the flowers are fully open to prolong the bloom time. Over-fertilizing can harm the plant, so follow the label instructions carefully.
Keeping Them Looking Great
A simple trick called “deadheading” makes a huge difference. As individual flowers fade and die, pinch or snip them off. This encourages the plant to put energy into making new buds instead of seeds.
Also, remove any yellow or dead leaves you see. This keeps the plant tidy and helps prevent disease. If the plant gets top-heavy, you can use a few small stakes for support, but proper sunlight usually keeps stems strong.
What to Do When Fall Ends
You have two main options after the first hard frost.
- Treat as an Annual: Simply compost the plant after it’s finished blooming. This is easiest.
- Try to Overwinter: If you want to save it, cut the stems back to about 4 inches after the foliage dies. Move the pot to a cool, dark place like an unheated garage. Water it very lightly just a few times over winter to keep the roots from completely drying out. In early spring, bring it back into the sun, repot with fresh soil, and hope for new growth.
Troubleshooting Common Problems
Even with great care, issues can pop up. Here’s how to handle them.
Yellow Leaves
This is often a sign of overwatering. Check that your pot drains well and let the soil dry out a bit more between waterings. It could also be a natural process as older inner leaves die off.
Wilting Plants
Wilting can mean two opposite things. Check the soil. If it’s bone dry, water immediately. If it’s wet, wilting could be root rot from too much water, which is a more serious problem.
Few or No Flowers
Insufficient sunlight is the most common cause. Mums need that direct sun to set buds. Also, make sure your are feeding them regularly during the growing season.
Pests
Aphids or spider mites might appear. A strong spray of water from the hose can often dislodge them. For persistent problems, use an insecticidal soap according to the directions.
FAQ: Your Mum Care Questions Answered
How often should I water potted mums?
Check daily. Water when the top inch of soil is dry. This could be daily in hot weather or every few days in cooler, cloudy conditions.
Can I keep my potted mums inside?
They are primarily outdoor plants. They need lots of sun and good air circulation, which is hard to provide indoors. They are best enjoyed on a sunny porch or step.
Why are my mums dying already?
The most likely culprits are too much water (causing root rot) or too little water. Check your watering habits and the pot’s drainage first. Lack of sun can also weaken them significantly.
Do I need to prune my mums?
For fall mums, just deadhead spent flowers. If you are overwintering a plant, you’ll cut it back hard after frost. For mums you plan to keep long-term, pinching back the growing tips in spring and early summer encourages a bushier shape.
Can I plant my potted mums in the ground?
Absolutely! After they finish blooming, you can plant them in a sunny garden spot. Cut them back, mulch well, and they may come back as perennials next spring.
With these essential tips, your potted mums will provide maximum color and enjoyment. Remember, it all comes down to a sunny spot, consistent watering, and a little regular care. Enjoy the brilliant show they put on each autumn.
