Plant Now, Thrive Later: Why Fall Is the BEST Time to Install Trees & Shrubs in Pennsylvania

When most people think about planting trees and shrubs, they picture springtime—the season of fresh beginnings and new growth. But for seasoned landscape professionals, we know fall is, in fact, the best time to start planting.

Wondering why? Read on to learn why fall is the smart and strategic time to get new trees and shrubs in the ground—and a few of our favorite picks for Pennsylvania landscapes:

Cooler Temperatures = Happier Plants

As air temperatures drop, trees and shrubs experience less stress during transplanting. Unlike summer heat, which can shock young root systems, fall offers mild days and cool nights—ideal conditions for new plants to settle in.

Warm Soil Encourages Root Growth

While the air cools down, the soil stays warm well into fall. That means your newly planted trees and shrubs can establish strong root systems before winter dormancy.

Some of our go-to choices for fall planting in Central PA include:

  • Serviceberry (Amelanchier canadensis): A native tree with spring blooms, summer berries, and glowing fall foliage.
  • Red Oak (Quercus rubra): A majestic shade tree that adapts well to local soils and provides habitat value.
  • Winterberry Holly (Ilex verticillata): A standout shrub with vibrant red berries that persist into winter and attract birds.
  • Fothergilla (Fothergilla gardenii): Known for its fragrant spring flowers and brilliant fall color in smaller spaces.

Fall Rain Reduces Watering Needs

With less evaporation and more consistent rainfall, fall planting often requires less manual watering than summer. That’s good for your plants and your water bill.

We still recommend monitoring moisture levels, especially during dry stretches in early fall, to help new roots settle in.

Fewer Pests and Diseases

Insects and many plant diseases are less active in the fall, which means your new plantings are less vulnerable to common threats like aphids, powdery mildew, or leaf spot fungi.

A Head Start on Spring

Fall-planted trees and shrubs wake up ready to grow in spring. Since they’ve already established roots over the winter, they can focus energy on above-ground growth earlier than those planted in April or May.

You’ll enjoy quicker leaf-out, stronger blooms, and a more mature look by next summer—especially with fast-establishing natives like Dogwood (Cornus florida) or Inkberry Holly (Ilex glabra).
