That feeling of regret when you realize the planting season is slipping away—we know it well. Many Sterling homeowners contact us in late summer fearing they’ve missed their chance to add that perfect shade or flowering tree. The uncertainty and worry about wasting a significant investment are understandable.
The great news is: No, it is absolutely not too late! In fact, for most deciduous trees here in Loudoun County, late summer and early fall offer the best time to plant. After 46 years of successful planting across Sterling, our team at SAB Lawn and Landscaping Inc. knows exactly how to use this critical window to ensure your new tree thrives. Forget the stress of spring planting; the fall season is nature’s gift to root establishment.
Why Fall Planting is the Secret to Success in Loudoun County, VA
When you plant in the fall, you are taking advantage of a unique climatic sweet spot specific to Northern Virginia’s USDA Hardiness Zone 7a. This season optimizes the conditions for underground growth, which is far more critical than growth above the soil line.
Reduced Stress, Rapid Rooting (The Dormancy Advantage)
Trees planted in the spring face immense pressure: they must simultaneously expend energy growing new leaves (vegetative growth) and establishing a new root system. This split energy focus can lead to significant transplant shock and failure. In contrast, fall planting allows the tree to enter its period of dormancy. With canopy growth slowing or stopping, the tree redirects nearly all its energy into unseen, rapid root development. The soil remains warm long after the air cools, creating an ideal environment for roots to spread and take hold before the deep freeze sets in.
Less Watering, More Resilience
Another critical advantage of planting as the scorching summer heat departs is the consistent moisture in the soil. Cooler days mean less evaporation, significantly reducing the watering demand compared to planting in the high heat of July or August. This reduced dependency on constant, heavy watering lowers the risk of either underwatering (which causes stress) or overwatering (which can lead to root rot).
Maximizing the Virginia Hardiness Window
In Loudoun County, which sits in Hardiness Zone 6B and 7A, planting windows are generous . While the first frost often occurs in late October, the ground does not typically freeze solid until much later. Professional planting is viable through November and sometimes into early December, depending on seasonal fluctuations. This prolonged window gives newly planted deciduous trees several crucial months to establish a strong root mass, ensuring they are fortified and ready to burst with vitality when spring arrives.
Pros and Cons: Navigating Seasonal Planting Challenges
Choosing the right time involves weighing the seasonal benefits against potential risks. Our 46 years of service ensure we manage these factors proactively.
Key Advantages of Planting Now
- Optimal Root Establishment: Warm soil temperatures and cooler air maximize root growth before winter.
- Reduced Pests and Disease: Many common garden pests start to die off or go dormant as temperatures drop, protecting your young tree from early attack.
- Less Transplant Shock: The mild, short days allow the tree to focus entirely on foundation building.
- Access to Nursery Deals: While availability may narrow, the fall often brings excellent opportunities for deals on mature stock, maximizing your investment.
Critical Risks and Considerations
While fall is ideal for many species, it is crucial to understand the risks. The primary challenge is limited stock availability in late season. More significantly, evergreens present a specific hazard. Unlike deciduous trees, evergreens retain their needles throughout the winter, meaning they require moisture year-round . If the ground freezes solidly, the newly established, small root system cannot draw up water, leading to a condition called “winter burn” where foliage dries out in the sun and wind . For this reason, SAB recommends focusing on robust deciduous shade or flowering trees in the late fall, unless specific winter protection plans are implemented for evergreens.

Planting a tree correctly is an exact science. Failure to follow established arboricultural standards results in poor health, expensive remediation, or the need for hazardous tree removal later.

Our Professional Planting Process
SAB’s experienced technicians follow an exacting protocol to ensure maximum root success:
Utility Check First: Before any digging begins, we always call 811 to locate all underground utilities, guaranteeing safety and compliance.
The Optimal Hole: We dig a hole that is two to three times the width of the root ball, but critically, no deeper . This wide, shallow approach encourages roots to grow outward into the native soil.
Root Flare Visibility: We ensure the root flare—where the trunk visibly widens at the base—is partially visible above the soil line after planting . This prevents moisture buildup and suffocating growth.
Strategic Backfilling and Staking: We gently but firmly fill the hole, ensuring the tree is straight. Staking is performed only if necessary in high-wind locations or for top-heavy trees, and stakes are removed within one year to prevent girdling .
Proper Mulching Technique: We apply organic mulch 3 inches deep in a broad “donut” around the tree, leaving a clean, 6-to-12-inch gap right next to the trunk flare . This prevents rot and rodent damage.
Initial Hydration and Follow-up Care: We provide initial heavy watering and clear instructions for weekly watering until the ground completely freezes, essential for establishment .
