Late Season Planting in Minnesota

When most people think of planting season in Minnesota, they picture spring and early summer. But savvy gardeners know that September—and even early October—is one of the best times to plant. At Otten Bros, we’ve been helping Minnesota homeowners grow smarter and plant better since 1953, and we’re big believers in the benefits of late-season planting.

If you plan to upgrade your landscape design, introduce low-maintenance plants, or start fresh with new garden landscaping, now is the time to act. Here’s why.

Why Late Season Planting Works So Well in Minnesota

Cooler Air, Warmer Soil

In early fall, the soil is still warm from summer, but the air temperatures are cooler and more stable. This creates ideal conditions for plants to focus on root growth instead of fighting heat stress. Strong root systems established now will help your plants thrive when spring returns.

Less Watering & Maintenance

The cooler temps and occasional fall rain mean less watering for you. Compared to the hot, dry stretches of midsummer, late-season plantings require much less attention, making it a great option for those leaning into low-maintenance landscape design.

Fewer Pests & Weeds

By September, many common garden pests are past their peak. Fewer insects and less weed pressure create a calm environment for new plantings to get established without competition or damage.

Best Plants for Fall Planting in Minnesota

Not everything loves a fall start, but perennials, shrubs, trees, and spring-blooming bulbs all thrive when planted in early fall.

Top Fall-Friendly Picks:

• Echinacea (Coneflower)
  
• Black-Eyed Susan
  
• Sedum ‘Autumn Joy’
  
• Ornamental grasses
  
• Hydrangeas
  
• Hostas
  
• Serviceberry trees
  

Many of these are excellent choices for low-maintenance yard designs, luxury landscapes, and easy backyard landscape designs. Bonus: These plants will be ready to grow and bloom next spring!

How to Get Started with Late Season Planting

1. Prepare Your Soil

Loosen the soil and add compost to improve structure and nutrients. Make sure the area has proper landscape drainage to avoid root rot during winter thaws.

If you’re working with a slope or need to control runoff, consider installing a concrete block retaining wall or speak with one of our landscape specialists about landscaping and water drainage solutions.

2. Choose the Right Spot

Think about your long-term landscape design ideas. Do you want color near your front walkway? A pollinator patch near your outdoor living space? Fall is a great time to make strategic planting moves to enhance your yard in all seasons.

3. Plant & Mulch

Plant at the same depth as your plants were growing in their containers. Water deeply once after planting. Then apply a layer of mulch (2–3 inches) to protect roots from temperature swings and lock in moisture.

Planning Hardscape Projects Around Fall Plantings

Fall is also a perfect time to get a jumpstart on future landscape projects that incorporate both plants and hardscaping elements like:

• Custom retaining walls for structure and erosion control
  
• Stepping stone walkway designs or paver walkway designs to connect areas
  
• A new concrete patio to expand your outdoor living spaces
  

Our team can help you blend new plantings with permanent design features for a polished, integrated look—perfect for residential landscaping upgrades.
