Fall Is for Trees: Why September Is a Great Time to Plant

If you’ve been thinking about adding a tree or larger shrub to your landscape, don’t wait until spring. September can be one of the best times to plant in Massachusetts.

Cooler air reduces stress on newly planted trees and shrubs, while soil warmed by summer encourages root development. Plant this fall, and your new addition can begin settling in before winter and be ready for a strong start next spring.

Why September Is Ideal for Planting

Early fall offers a combination of conditions that can make establishing trees and shrubs easier.

Benefits of September planting include:

• Cooler temperatures that reduce heat stress
• Warm soil that encourages root growth
• Slower moisture loss than during summer heat
• Less pressure on plants to produce new top growth
• More comfortable planting weather for gardeners

Although you may not see much happening above ground, roots can continue establishing while soil conditions remain favorable.

Give Trees a Head Start on Spring

When a tree is planted during fall, it has an opportunity to begin developing roots before winter dormancy.

Once spring arrives, that tree is already in its new home. Instead of dealing with the stress of being transplanted as temperatures begin rising, it can put its energy into continued establishment and new growth.

Add Shade, Privacy and Structure

Trees and larger shrubs aren’t just beautiful. They can completely change how a landscape looks and functions.

Consider adding them to:

• Create shade around patios and outdoor living areas
• Add privacy between neighboring properties
• Frame entrances and walkways
• Create natural screening
• Add spring flowers or fall foliage
• Provide evergreen color throughout the year
• Create habitat and food sources for wildlife

Think about what you’d like your landscape to accomplish, then choose plants that help achieve that goal.

Choose the Right Plant for the Right Place

Trees and shrubs are long-term additions, so choosing the proper location is important.

Before planting, consider:

• Mature height and width
• Sunlight throughout the day
• Soil and drainage
• Proximity to buildings and walkways
• Overhead wires
• Available root space
• Desired seasonal interest

That small tree at the garden center may eventually become a major part of your landscape. Planning for its mature size helps prevent problems later.

Plant at the Proper Depth

Planting too deeply is a common mistake with trees and shrubs.

Dig the planting hole wider than the root ball, but avoid setting the plant deeper than it was previously growing. The top of the root ball should generally remain at or slightly above the surrounding soil level.

Backfill with soil, water thoroughly, and avoid heavily compacting the soil around the roots.

Don’t Stop Watering Because It’s Fall

Cool weather doesn’t eliminate the need for water.

Newly planted trees and shrubs need consistent moisture as their roots begin growing into the surrounding soil. Continue checking soil moisture throughout fall, especially during dry stretches.

Deep, thorough watering is generally more beneficial than frequent shallow watering.

Finish with a Layer of Mulch

Mulch can help newly planted trees and shrubs by conserving moisture, moderating soil temperatures, and reducing competition from weeds.

Spread mulch over the root zone, but keep it away from direct contact with the trunk or stems. Avoid creating a mound of mulch around the base of a tree.

Plant Now and Enjoy It for Years

Trees and larger shrubs are investments that can become more beautiful and valuable to your landscape with every passing year.

Take advantage of September’s cooler temperatures and warm soil to tackle that landscape project you’ve been considering. A tree planted this fall could be providing shade, privacy, flowers, fall color, or evergreen beauty for many years to come.

Frequently Asked Questions

Is September a good time to plant trees in Massachusetts?

Yes. September’s cooler air and soil that remains warm from summer can provide favorable conditions for establishing many trees and shrubs.

Can I plant larger shrubs in fall too?

Yes. Many larger landscape shrubs benefit from the same fall conditions that make this a good season for planting trees.

Do newly planted trees need fertilizer?

Focus first on proper planting, watering, and choosing the right location. Fertilizer needs can vary depending on the plant and soil conditions.

How often should I water a newly planted tree?

Check the soil regularly and water deeply when needed. Weather, soil type, plant size, and rainfall will affect how frequently watering is necessary.

Should I mulch around a new tree?

Yes. Mulch helps conserve moisture and moderate soil temperatures. Keep mulch away from direct contact with the trunk.
