Best Flowers To Grow In Minnesota Fall
These flowers are tested in Minnesota’s short growing season. They bloom from late August through October, sometimes into November. Each one handles light frost and continues flowering after other plants fade.
Chrysanthemums: The Fall Classic
Mums are the backbone of autumn gardens. They come in gold, bronze, red, and purple. Garden mums are perennial in Minnesota if planted early enough. Pot mums are usually treated as annuals.

- Fertilize with liquid feed every two weeks
Pansies bounce back after snow melts. They are perfect for containers and borders. Pair them with ornamental kale for a stunning display.

Planting Tips For Minnesota Fall Gardens
Timing is everything in Minnesota. Plant fall flowers in late August or early September. This gives roots time to establish before the ground freezes.
Soil Preparation
Test your soil pH. Most fall flowers prefer neutral to slightly alkaline soil. Add compost to improve drainage and fertility. Remove weeds before planting.
- Amend clay soil with sand or perlite
- Add organic matter to sandy soil
- Use a balanced fertilizer at planting time
- Water deeply after planting
Watering Schedule
Fall in Minnesota can be dry. Water new plants regularly until the ground freezes. Established plants need less water as temperatures drop.
- Water in the morning to prevent disease
- Use drip irrigation or soaker hoses
- Reduce watering after first frost
- Stop watering when ground freezes
Frost Protection
Light frosts are not a problem for these flowers. Hard frosts below 28°F can damage tender growth. Cover plants with row cover or old sheets if a hard freeze is forecast.
- Remove covers in the morning
- Water soil before a freeze to retain heat
- Mulch around roots with straw or leaves
- Bring container plants indoors or to a sheltered spot
Deadheading And Pruning
Remove spent flowers to encourage more blooms. Cut back dead foliage after hard frost. Leave some seed heads for birds.
- Deadhead pansies and snapdragons weekly
- Cut mums back to 6 inches after flowering
- Leave sedum and ornamental grasses for winter interest
- Clean up diseased foliage to prevent problems next year
Container Gardening For Fall
Containers are ideal for fall flowers. You can move them to protect from frost. They also add color to patios and entryways.
Choosing Containers
Use pots with drainage holes. Clay pots dry out faster than plastic. Choose containers that match your home’s style.
- Use large pots for better root growth
- Add pot feet to improve drainage
- Group pots for visual impact
- Use lightweight pots for easy moving
Planting Combinations
Combine thriller, filler, and spiller plants. Use mums as thrillers, pansies as fillers, and ivy as spillers.
- Thriller: Tall sedum or ornamental grass
- Filler: Pansies or kale
- Spiller: Creeping jenny or vinca
- Add ornamental peppers for extra color
Care For Container Plants
Container plants need more water than garden beds. Check soil daily. Fertilize every two weeks with liquid feed.
- Water until it runs out the bottom
- Use slow-release fertilizer at planting
- Protect from hard freeze by moving indoors
- Replace plants that die after frost
