When is the best time to have tree pruning done?
Many tree species can tolerate light pruning throughout the year. Although, pruning during mid spring to early summer is favorable for most tree species. This is because the tree is actively growing and the compartmentalization of pruning wounds is not delayed by dormancy.
Why hire an arborist?
A healthy landscape is typically comprised of trees, shrubs, grass, shade gardens and water features. Each one of these components can be of great investment, both in time and financially. Trees and shrubs are living elements in your landscape and must be treated accordingly to sustain their value and vitality.
The landscape you surround yourself with should be healthy, beautiful and sustainable without constant intervention. It's important to recognize that large trees stand within a spectrum of asset verses liability. The balancing act that is your tree's health can swiftly shift if not properly addressed. Not all tree care providers are properly trained or equipped to advise you on the state of your trees health.
"An arborist is a specialist in the art and science of caring for individual trees. An ISA Certified Arborist is trained to understand the needs of trees and provide the care and maintenance necessary to enhance a tree’s health, beauty, and structural soundness." -International Society of Arboriculture (https://pnwisa.org/hire-an-arborist/benefits-of-hiring-an-arborist/)

What would be considered a bad tree planting spot?
A good general rule of thumb: When looking for a place to plant a tree, try the outskirts of your landscape, away from any structures. Avoid overhead or underground utilities, septic fields or any other significant infrastructure. Most tree species can be planted at least 15' from a house.
Why is tree topping a bad practice?
Tree topping is typically preformed to manipulate the height of a tree. This expensive chore is absolutely terrible for a trees health. Tree topping actually encourages your tree to grow larger long-term, but at the expense of stability and health. When large topping cuts are made, the tree produces many new epicormic sprouts, otherwise known as water sprouts or suckers. These new growths are not attached in a strong manner like the pre-existing structure and they grow extremely fast which makes them weak. In addition, the large pruning wound will decay near the attachment point of these sprouts. This produces a very hazardous tree. When you top a tree, you doom it to a lifetime of struggles, followed by a premature death.

My neighbors tree is hanging into my yard, can i cut it back?
If plant material is hanging into your yard, you can prune the tree or shrub back to the property line. However, if you damage or kill the tree your neighbors tree you will be liable. Furthermore, pruning "at the property line" is not very conducive to best management practices for tree care. Improper pruning can actually encourage regrowth back into your property and severely damage a tree permanently. More often than not, disputes between neighbors regarding their trees can be resolved with the assistance of a certified arborist. We are experienced in conflict mitigation between home owners and pride ourselves on finding solutions.
How do i know how big my tree will get?
Tree height, canopy spread, trunk diameter and root zone size is determined by a combination of species genetic potential and environmental strain. To find out how large your tree will grow, you will need to know exactly what type of tree it is. Once you know tree type, you'll be able to find it's average and max growth potential sizes. These predictions may vary greatly depending on specific circumstances. A local arborist will be more familiar with local trees than Wikipedia. If you're in the Eugene or surrounding area, give us a call. We will provide you with concise information regarding our local trees.
