Sources

The Master Gardeners of Northern Virginia was the primary resource for most of this information, excluding the American Elderberry. Other resources include:

Site Selection, Planting and Ongoing Care

Providing the best environment for your tree or shrub to thrive starts with selecting the best location for your tree type. The projected growth size, soil and sunlight needs, and the distance from structures and power lines all need to be considered. The following resources provide great information to help you select the best place for your new tree or shrub.

Planting and Caring for a Seedling

The seedlings will be small, about 12 inches tall. The great news about seedlings is that they are very easy to plant and the primary requirements are making sure the hole is deep enough and ensuring that they get plenty of water over the next couple of weeks. Make sure the soil is moist but not overly wet. The first video below shows how you can use an empty soda bottle to protect your seedling.

Ongoing Care

The TreesAreGood website is a great resource for tree care and finding an arborist, when needed. Plant NOVA Trees is another good resource, in both English and Spanish. Several good links can be found on this site, under Tree Care.

Tree Stewards are trained volunteers who love sharing their knowledge of arboricultural
best practices to keep our community trees maintained. We’d love to come to meet with
you and talk about your trees!

While we are not certified arborists and cannot determine whether a tree is safe or
unsafe, we can help you determine what questions to ask a qualified professional if you
have concerns. We can also offer guidance on selecting the best location for planting a
new tree. We’re available to visit yards of homeowners, condo green committees, and
apartment managers. To request a Tree Steward visit, please fill out this form Request for Tree Steward Neighborhood Visit or scan the QR code below with your phone.

A Tree Planting Milestone in Alexandria

Tree Stewards of Arlington and Alexandria

A milestone in Alexandria history was made on Saturday, October 11th as the Alexandria Beautification Committee (ABC), in conjunction with the Tree Stewards of Arlington and Alexandria, conducted the first city-sponsored tree planting on private property.  Recognizing that Alexandria would be hard pressed to meet its tree canopy equity goals of 40% by planting only on existing public land, the ABC set out to partner with properties on the West End to bring the City closer to their goal.

The Hamlets once occupied a large footprint near Beauregard and contained lots of old growth trees but in subsequent years the property had been broken up into a handful of separate properties with little to no tree planting for the last several decades. Liz Gelfer, ABC Vice Chair, and commission member Russ Bailey walked each of the properties and hoped to use Lynbrook Apartments for the inaugural planting. Fortunately, the property management team of Morgan Properties was very excited about the partnership.

Neighborhood Tree Walk at Quincy Park

On a beautiful Saturday in September, Tree Stewards Paul Kaplowitz and Russ Bailey led an engaging and educational tree walk at Quincy Park in Arlington. The event, organized in partnership with Arlington Central Library, brought together tree lovers from across the community to learn about Arlington’s trees.

Earlier this summer, Tree Stewards mapped the trees in Quincy Park and identified 19 different species! The park is home to many Willow Oaks, Northern Red Oaks, Red Maples, at Southern Catalpas. Attention was also brought to the Bradford Callery Pears, a commonly planted but invasive species that should be avoided in future landscaping.

Participants asked thoughtful questions throughout the walk and a good time was had by all! The strong turnout and enthusiasm suggest there’s plenty of interest in more programs like this and Tree Stewards looks forward to leading more Neighborhood Tree Walks in the near future–we hope to see you there!

Virginia Acorn and Nut Collection Season is here!

From September 1st to October 15th, the Virginia Department of Forestry (DOF) collects a variety of species of acorns and nuts from local trees and sends them along to the Augusta Nursery in Crimora, VA to be cultivated into tree seedlings that will become the forests of tomorrow. Seedlings grown from Virginia-grown seed generally produce trees that will best thrive in our state’s climates. These seeds will produce next year’s hardwood seedling crop, which will be sold to Virginia’s forestland owners. 

Interested in sharing your acorns or nuts, or possibly know where a healthy specimen tree is located? Visit Seeking Acorns and Nuts to Grow Seedlings to see the species needed for 2025 and learn how to get started!

Springtime Tree Care Tips for Homeowners

As the temperatures rise and flowers begin to bloom, spring is a critical time for the trees in your yard. Whether you have towering oaks, leafy maples, or flowering cherries, caring for your trees during this season can help them thrive throughout the year. As tree stewards in Arlington and Alexandria, we understand how valuable trees are to our local landscapes, and we want to share some practical tips that homeowners can implement right now to support their trees during this beautiful, yet vital, time of year.

1. Watering Wisely

Spring can be unpredictable in terms of rainfall, and trees need consistent moisture to support new growth. Deep watering is essential, particularly for newly planted trees or trees that have been stressed by previous seasons. Aim to water deeply once or twice a week (depending on rainfall) to encourage roots to grow deep into the soil. A slow drip or soaker hose is ideal, as it allows the water to reach the roots without causing runoff.

2. Mulch for Moisture Retention

Applying a 2-4 inch layer of mulch around the base of your trees can help retain moisture in the soil, regulate temperature, and suppress weeds. Make sure to keep the mulch away from the tree trunk to avoid rot—mulch should form a “donut” shape around the tree, not a “volcano.” Wood chips, shredded bark, or leaves all work well, but avoid using synthetic mulches that may not allow proper water penetration.

3. Pruning Dead or Damaged Branches
