By Nancy Penrose


There are many reasons why a healthy tree can get sick, such as pests, injuries, disease and poor maintenance. Even the environment can adversely affect a tree’s well-being.

There are several ways to tell if a tree is doing poorly. Some of the more obvious signs include areas of decay and evidence of infestations. A tree may also have health issues if it isn’t growing or has prematurely dropped its leaves. Other indicators of illness include early ripening, wilting, loss of color, and trunk or branch abnormalities.

Trees can become infected from pests such as aphids, root weevils, leafrollers, spider mites and the codling moth. The pests will either burrow into the tree or start feeding on it. Sometimes they do both. Continue reading

By Nancy Penrose

A recently planted tree can take up to two years or more to become established. An established tree will have roots that extend below the drip line, the area beneath the canopy where water from the tree drips into the ground.

Taking care of a new tree is important. When a tree is planted or a tree transplant is done, it can lose some of its root system and go into shock for many months before it recovers. During this period, the tree is in a weakened state and more susceptible to pests and root disease. Even changes in the weather and soil can have an adverse effect on your new tree’s growth and health. Continue reading

Big Trees Inc. Transplants 20 foot Beech Tree for City Park in Bellevue

SNOHOMISH, WA: Big Trees Inc., (, a tree transplant and tree nursery company in the Seattle area, was asked to transplant a large Beech tree in Kelsey Creek Park for the City of Bellevue, Washington. The transplant went smoothly, and the tree will get the opportunity to continue to thrive in its new location.

Big Trees was approached about this situation when it became clear that some adjustments were necessary to the park’s layout. A number of changes were required, and that necessitated moving the playground to the tree’s location. There was a consensus that the tree was an important part of the park’s aesthetic and general ambience, and the decision was made to have it transplanted to another part of the park.

Big Trees prepared the root ball for handling, keeping the size and shape of the tree’s canopy and the subgrades the tree had been growing in, in mind when shaping the ball. The root ball was wrapped in progressive layers with burlap and barrel lacing of rope. The following day, the crew utilized a large all-terrain forklift to move the 20’ tall, 8” diameter trunk Beech tree to its new location. Once the tree was set and spun correctly, the wrapping was removed from the root ball. The Beech tree was replanted and secured to maintain the integrity of its root system and protect it against any strong breezes.

Nancy Penrose, owner of Big Trees, stated “Our crews always do their best to manage these transplants, from addressing the appropriate dimensions of what should be incorporated into the root ball, to managing the equipment’s impact on the property, while handling the tree and moving it to its new location. We always make our best efforts for a successful experience for everyone and everything involved.”

Nancy Penrose is the owner of Big Trees, Inc. (, located in Snohomish, WA, in the Seattle area. The company is one of the largest tree nurseries in the Seattle area with over 120,000 trees available in over 300 varieties.

Protect Your Landscape When Remodeling

By Nancy Penrose

Renovation and construction projects can cause significant damage to your property’s landscape. In addition to breaking branches and tearing bark, workers and equipment can seriously injure root systems that provide your foliage with water and nutrients. Any type of excavation or the addition of patios, driveways and walkways can also impact the health of your plants.

If you plan to remodel, take steps beforehand to protect your trees and shrubs. Start by creating paths with fencing and signage that keep foot traffic and equipment away from your plants and plant roots. You can also use layers of wood chips to prevent plant and tree roots from suffocating due to soil compaction.

Will the site need to be cleared? Taking trees and shrubs away that provide sun and wind protection for other foliage can lead to more landscape damage and loss over time.

One way to avoid landscape damage is to store trees and shrubs during construction and re-plant them after the project has been completed.

We do this all the time for both home and commercial projects. The process starts by carefully preparing the trees or shrubs for transportation. When big trees are involved, a root ball will need to be created. Root balls contain both the plant’s roots and surrounding soil. The size of the tree determines the diameter of the ball. Large trees will have large root balls, sometimes up to 10 feet or more in diameter.

Once the trees and shrubs are ready for transport, we bring them back to our nursery and take care of them until the construction work is done. Plants can usually remain in storage for up to 3 years.

Storing trees can prevent the loss of valuable foliage. If you have questions about how and when to store trees and other foliage, contact one of our big tree specialists. We can go over all of your options and help you make the best decision possible regarding your landscape.
