The Ultimate Fall Planting Guide: Why Autumn is the Best Time to Plant Trees and Shrubs

August 12, 2025

When it comes to giving your plants the best start in life, timing is everything. Fall offers the perfect conditions—warm soil, cool air, and often more consistent rainfall—making it the ideal season for establishing strong, healthy root systems before winter. Whether you garden in the north or south, fall planting can help your trees and shrubs flourish for years to come.

Why Fall is the Best Time to Plant Trees and Shrubs

Warm Soil and Cool Air Create Perfect Conditions

By fall, summer heat has warmed the soil, but cooler air temperatures reduce stress on new plants. Roots grow best in soil temperatures above 55°F, which often continue well after the first crisp mornings arrive.

Less Water Stress

Cooler temperatures reduce evaporation, allowing plants to retain more moisture and focus energy on root development rather than survival.

A Head Start for Spring Growth

Roots keep growing until the ground freezes, setting up your plants to leaf out stronger and fuller when spring arrives.

Fewer Pests and Diseases

Many plant pests and diseases slow or disappear in cooler weather, lowering risks for newly planted trees and shrubs.

 

When to Plant in Fall by USDA Grow Zone

Fall planting works nationwide, but your timing depends on your USDA grow zone. A general rule: plant 4–6 weeks before your area’s first hard freeze.

  • Zones 3–5: Plant in early fall so roots establish before freezing temperatures arrive.

  • Zones 6–9: Enjoy a longer planting season—often into November or December—thanks to milder winters.

  • Zones 10–11: Fall is often the best time to plant, avoiding summer heat and allowing months of root growth before warm weather returns.

Special Note for California, Arizona, Texas, and Florida (Zones 6–9):

These regions benefit from an extended fall planting season, making it possible to plant well into late fall or early winter. This is an excellent time to add evergreens, flowering trees, and shade trees while soil conditions are still favorable.

How to Plant Trees and Shrubs in Fall


1. Choose the Right Location

Match your plant’s light, soil, and moisture requirements with your landscape conditions.

2. Dig a Proper Hole

Dig 2–3 times as wide as the root ball but no deeper than the root flare.

3. Position and Backfill

Place the plant so the root flare is level with or slightly above the soil surface. Backfill with native soil, breaking up clumps.

4. Water Thoroughly

Water deeply after planting to settle soil and remove air pockets. Continue watering 1–2 inches per week until the ground freezes.

5. Mulch for Moisture Retention

Apply 2–3 inches of mulch around the base, keeping it a few inches away from the trunk.

Aftercare Tips for Fall-Planted Trees

  • Water Until the Ground Freezes – Roots remain active until soil temperatures drop below freezing.

  • Protect in Harsh Winters – In colder zones, wrap young evergreens with burlap or create windbreaks.

  • Deep Soak for Evergreens – Give evergreens a final deep watering before the soil freezes to prevent winter burn.
