Earlier this week, we posted an article featuring expert tips on tree care, including irrigation, disease prevention and maintenance. One of the aspects mentioned was pruning, a crucial maintenance measure that, unfortunately, is often performed improperly. To gain some insight into correct pruning procedure, watch this informative video by Diamond Certified Expert Contributor Laural Roaldson, owner of Laural Landscapes, Inc.

Despite being the largest of all plants, trees are surprisingly easy to overlook. Maybe it’s because their serene, stationary disposition causes them to blend in with their surroundings; maybe we just don’t look up often enough. Either way, like any plant, trees require water, nutrition and ongoing maintenance, so it’s important to take care of the ones on your property. To learn about some tree care basics, we’re joined by six Diamond Certified Expert Contributors in the tree service and landscaping fields.
Tree irrigation and nutrition
The first step in caring for a tree is simple: water it. However, as Chris Chapman of Horticultural Services, LTD explains, tree irrigation is something property owners often get wrong. Continue reading “Diamond Certified Experts: Tree Care 101” »

With unique and majestic forms that add character to the Northern California landscape, it’s no surprise that Bay Area residents love their oak trees. However, due to rising concerns about the health of indigenous oaks—particularly the recent epidemic of sudden oak death—many property owners have gone on the defensive and become more proactive about preventative maintenance. While this is certainly a positive trend, some people fail to realize that oak trees tend to require minimal maintenance, which means overdoing it can do more harm than good.

You might not realize it, but your home may be a target if it’s bordered by tall trees. Every year, falling trees account for millions of dollars of damages to homes in the United States. For this reason, if you’re unsure about the condition of a tree near your home, it’s a good idea to have its health evaluated. While a DIY examination is no substitute for the expertise of a licensed arborist, there are various signs and symptoms you can look for to assess the health of a tree.
First, look for visible indications of the tree’s overall health. Signs of good health include full growth; vibrant leaves; and strong, contiguous trunk bark. In contrast, signs such as sparse or stunted growth; discolored, withered or spotted leaves; and fragmented or peeling bark may be outward manifestations of ill health.

Many people think of trees as entities that operate independent of human involvement, but there are many cases where intervention can foster significant improvements, both in the interest of economics and general health. One such method of intervention is called “thinning.” While on the small scale this term refers to the selective removal of branches to improve a tree’s overall health, on a larger scale it denotes a selective removal of whole trees from certain areas of a landscape.
Thinning is most often applied in areas where overcrowding intensifies competition between neighboring trees. This strenuous competition can be detrimental to particular “underdog” stands of trees, especially where environmental factors such as drought, insect infestations or extreme temperature come into play.

Trees take decades, sometimes centuries, to grow to maturity, and they must be cared for with more expertise than shrubbery and ground covers. A qualified arborist needs an in-depth knowledge of trees that a general landscaper usually doesn’t possess. Tree work also poses different safety and liability concerns, so arborists must carry more insurance and be better trained in how to safely work with and among trees.
Accreditation and certification are the most important things to look for in a tree care company. Are its arborists certified by the International Society of Arboriculture? Are they accredited by the Tree Care Industry Association? You should also ask how long the company has been in business. Although it’s a rigorous test to become a certified arborist, some recent graduates don’t have the same amount of practical knowledge that comes from years of onsite experience.
Insurance and safety are especially important when it comes to tree care—unlike most standard landscaping work, missteps can result in serious property damage or severe injuries. Make sure you ask the company how much liability insurance it carries and what it covers. The accreditation process includes safety, so an accredited tree care company should have a good safety record. If you have doubts or concerns, run a workers’ compensation report to see what the safety record is for yourself.
Another question to consider: What does the arborist do with the wood chips and biomass that are generated from tree care? Does the firm simply cart it to a landfill, or is it used to create bio-fuel and Green electricity?

My neighbor in Sonoma has some beautiful trees, but a few of the limbs and branches are blocking views. I started wondering whether I was within my rights to trim some of those branches, given that they’re dangling over the fence and onto my property. Who better to ask than Darren Edwards, owner of Advanced Tree Service, a Diamond Certified company? According to Mr. Edwards, “You may have someone trim your tree without your neighbor’s permission. You’re allowed to go back to the property line. You can’t go over the property line. But so long as it doesn’t damage the tree’s health or integrity.” It’s also a good idea to discuss any limb trimming with your neighbor first, just to keep up good relations. As a side note, we also had a neighbor’s tree limbs growing onto our power lines. One call to PG&E and they came right out to remove the ones that might be a safety hazard.

A professional arborist like James Cairnes, owner of a Small World Tree Company, a Diamond Certified company, believes that all pruning should preserve as much of the tree and look as natural as possible. Young trees need what’s called “formative pruning,” where you take out competing stems that could cause problems in the future. Directional pruning is also done on many types of trees, mainly to improve the structure and aesthetics of a tree.
Mr. Cairnes is often asked to help with view restoration. That means cutting off branches with the idea of balancing the homeowner’s view while maintaining the integrity of the trees. Sometimes fruit production is the goal for trimming and pruning, and another specialty is Asian pruning, which used to achieve a certain look for the landscape and garden.
