In Menlo Park, some of the most common tree pests and diseases include Whitefly, Thrips, and Scale Insects. Here are signs and symptoms of how these pests and diseases can affect your trees. 

• Whitefly: Whitefly infestations cause leaf mottling, yellow spots, curling, premature defoliation, and twig withering.
• Thrips: Thrips infestations cause yellow or bleached leaf spots, deformed leaves, and petal splotches. As damage worsens, leaves appear silvery with black spots, wilt, die, and drop off.
• Scale Insects: Scale infestations cause small, yellow-mottled leaves, canopy thinning, leaf drop, and branch dieback.

A Plant Health Care (PHC) Program is a proactive, year-round plan to keep your trees and shrubs healthy and pest-free. Our certified arborists focus on prevention and early detection by monitoring soil health, nutrients, insects, and disease. Based on your property’s needs, we create a customized care plan that may include fertilization, pest management, pruning, and soil improvement. 

Some tree species, like birch, sycamore, silver maple, and redbud trees, naturally shed bark as they grow, while other species shed bark as a sign of disease, pests, or extreme temperature damage. If your tree has healthy-looking bark under the shed, then it’s usually safe. Read our blog to learn more about bark shedding.

Yes! Mulching around trees helps retain soil moisture, reduce weeds, improve soil nutrients, and regulate root temperature. Without mulch, tree roots must compete with grass for water and nutrients, which can slow growth and weaken the tree. Learn more about the benefits of mulching in our blog.

For best results, apply 2–3 inches of organic mulch around the tree, keeping it a few inches away from the trunk. Proper mulch installation is essential for the long-term health of your trees and plants.
