Insect Pest Control On Trees & Shrubs

The finely landscape homes in the Newport Coast area are too great a temptation for many insect pests to pass up. Some insect and mite pests found in the Newport Coast area can severely damage or even kill valuable landscape trees and shrubs. Depending on plant location and the insect or mite we provide pest control via tree spraying, insecticide soil injections, or tree trunk injections. Our tree service can help control a variety of plant damaging insect and mite pests including:

•Asian Citrus Psyllid
•Leafminer Insects
•Lerp Psyllid
•Scale Insects
•Spider Mites
•Tree Borers

While many insect and mite pests are controlled with tree spraying using traditional insecticides some can be controlled using certified organic pesticides.

Tree Disease Control

The climate of the San Joaquin Hills area allows for the proliferation of many tree and shrub diseases. Our tree service offers tree spraying to minimize the impact of these tree and shrub diseases on the health of your landscape plants. Sims Tree Health Specialists can help with control of:

•Apple Scab
•Citrus Greening Disease
•Oleander Leaf Scorch
•Palm Tree Diseases
•Peach Leaf Curl
•Pierce’s Disease
•Pitch Canker
•Powdery Mildew
•Sudden Oak Death
•Xylella fastidiosa

Spraying trees to control tree disease involves time-sensitive treatments. Call Sims Tree Health Specialists today if you believe you may be in need of tree or shrub disease control treatments. We also offer tree spraying to prevent or reduce fruit production on ornamental Olive trees.

Pre & Post Construction Care For Trees

Construction activity around trees often leads to significant tree decline or death. Often, construction damage to trees doesn’t kill a tree until 5 or 10 years after the construction has been completed. This means that if proper action is taken many trees in construction areas could be saved! Whenever possible, an arborist should be consulted before construction even begins. Consulting an arborist before construction begins is the best way to avoid tree loss after construction. Sims Tree Health Specialists can aid you with:

•Tree survey prior to construction
•Reviewing site plans to determine the impact on trees
•Implementing a tree preservation plan before construction begins
•Monitoring trees during construction
•Providing tree recovery services after construction
•Restoring soil grade over tree roots after construction
•Preserving historic trees, protected trees, or heritage trees during construction


Laguna Beach, CA

Despite the concerns of some Laguna Beach residents, the Laguna Beach city council approved the removal of five Eucalyptus trees in Bluebird Canyon. Southern California Edison is worried that the mature Eucalyptus trees near the power lines could pose a significant hazard.

Laguna Beach residents have mixed feelings on large Eucalyptus trees. On the plus side is that large trees, in general, add to property values. The large Eucalyptus trees also provide perches for birds of prey. The osprey, brown owls, and red-tail hawks in the Laguna Beach area consume thousands of rodents each year.

A negative aspect of large Eucalyptus trees is that they tend to randomly shed large branches and, even when they are properly pruned, can uproot. A large Eucalyptus tree can weigh several tons. Uprooted Eucalyptus trees have damaged sidewalks, driveways, decks, houses, and have caused death and injury to many people in California over the years.

Eucalyptus trees are native to Australia, but have been planted in many areas of California. If you have a large Eucalyptus tree on your property it should be periodically inspected by a certified arborist. In addition to normal tree pruning needs, Eucalyptus trees can be infected by root rot which can increase the possibility of uprooting.

Tree & Shrub Feeding

When trees and shrubs are planted in Newport Beach landscapes they are immediately placed in an unnatural setting. They immediately face competition with turf, poor soil conditions, and attack from insect pests that often place undue stress on your plants. Our tree feeding service can counteract many of the stresses faced by landscape plants in Newport Beach and improve the health and vigor of your valuable trees and shrubs.

Soil Enhancement Treatments

Under certain conditions tree feeding alone may not be enough to improve the health of your trees. When trees are planted in nutrient-deficient subsoil or soil compaction has occurred over tree roots more aggressive action should be considered. When trees are extremely sick or heavily damaged by construction activities, the professional arborists at Sims may recommend other root stimulant treatments such as:

•Root zone aeration
•Radial trenching
•Vertical mulching
•Soil injections of beneficial fungi or bacteria

Tree Consultation

When homeowners in Laguna Beach have tree care questions they often turn to the professional arborists at Sims for answers. Our arborists can evaluate the trees in your landscape and provide tree maintenance plans to keep your trees as healthy as possible. We can help you decide which trees need insect or disease protection and which trees will benefit most from tree feeding or other tree care services.
