Why Fall Is One of the Best Times to Plant

Spring may get most of the attention when it comes to gardening, but fall is one of the best planting seasons in Massachusetts. Cooler air combined with soil that is still warm from summer creates favorable conditions for establishing many trees, shrubs, and perennials.

Planting in fall gives roots time to begin establishing before winter, helping plants get a strong start when spring arrives.

Cooler Weather Means Less Stress

New plants can struggle when they’re transplanted during periods of intense summer heat. Fall’s cooler temperatures reduce stress and help plants transition more comfortably into their new surroundings.

Fall planting offers several advantages:

• Cooler temperatures reduce transplant stress
• Warm soil encourages root development
• Moisture doesn’t evaporate as quickly as during summer heat
• Plants can focus more energy on their roots
• Established roots give plants a head start in spring

While the garden may appear to be slowing down, plenty can still be happening beneath the soil.

Warm Soil Encourages Root Growth

One of fall’s biggest planting advantages is soil temperature.

The air may feel noticeably cooler, but the ground holds summer warmth much longer. This gives roots an opportunity to grow and begin establishing before colder conditions arrive.

A stronger root system helps plants access the water and nutrients they’ll need when active growth resumes.

Plant Trees and Shrubs

Fall is a great time to tackle some of the larger projects on your landscape wish list.

Consider adding trees and shrubs for:

• Shade
• Privacy and screening
• Spring flowers
• Fall foliage
• Evergreen structure
• Wildlife habitat
• Landscape focal points

Before choosing a plant, consider its mature size, sunlight requirements, soil conditions, drainage, and available space.

Add Perennials Now

September is also a great time to look around the garden and identify areas that could use more color, texture, or seasonal interest.

Planting perennials in fall allows many varieties to begin establishing roots before winter. When spring arrives, they’ll already be in place and ready for another growing season.

It’s also a perfect opportunity to add plants with different bloom times so there’s something interesting happening throughout the year.

Keep New Plantings Watered

Cooler temperatures don’t mean you can forget about watering.

New trees, shrubs, and perennials still need consistent moisture while becoming established. Check the soil regularly and water deeply around the root zone during dry periods.

Deep watering encourages roots to grow farther into the surrounding soil rather than remaining close to the surface.

Finish with Mulch

Adding mulch after planting helps conserve soil moisture, moderate temperature fluctuations, and reduce competition from weeds.

Spread mulch around the root zone, but keep it away from direct contact with tree trunks, shrub stems, and perennial crowns.

Plant This Fall for a Better Spring

Fall isn’t the end of gardening season. It’s another opportunity to improve your landscape.

Whether you’re adding a shade tree, creating privacy with shrubs, or filling garden beds with perennials, planting now can give your landscape a head start for next year.
