Pruning for flowering trees is dependent on the species. Here are a few useful tips. https://www.bartlett.com/tips/Pruning-Flowering-Trees.cfm

http://www.malibutimes.com//article_64aeb596-7796-11eb-9e6 The polyphagous shot-hole borer and the Kuroshio shot-hole borer (Euwellacea species) are recently introduced, non-native beetles that are having devastating effects on landscapes, forests, and agriculture in southern California. These pests are especially damaging because they introduce various pathogenic fungi, including Fusarium euwallaceae, which can rapidly kill some trees. These pests have dozens of host plant...s that are broken down into three categories: 7 Non-hosts: beetles attack the plant and are repelled without fungal introduction 7 Fungal hosts: beetles introduce the lethal fungus, but do not reproduce 7 True hosts: beetles introduce the lethal fungus and reproduce successfully True hosts are plentiful in landscape plantings, and include many native trees such as coast, valley, and Englemann oaks; sycamore; bigleaf maple; boxelder; and blue palo verde. Non-native true hosts common in the landscape include several other oak and maple species, avocado, coral tree, camellia, acacia, and many others. Signs of shot-hole borer attack include multiple small holes often surrounded by white crust, wet bark, or both. Management options for these insect/ pathogen combinations are currently being researched by several entities, including scientists in the University of California system and Bartlett Tree Research Laboratories (West). So far, several fungicides have been shown to impede the pathogen in culture, but field trials in trees have been less successful. Systemic insecticides may kill the beetles and their larvae, but do not prevent introduction of the lethal pathogen. Combination treatments of a fungicide and insecticide are currently registered and research has shown this to be the best option for trees that have already been attacked. For susceptible trees that have not been attacked, protective bark applications are available, although are not 100% effective. See more

On International Women's Day, we celebrate all the Bartlett women who are out in the field, in the lab or in the office - working hard and getting the job done while serving as role models for the next generation of tree care workers! #internationalwomensday2021

Another happy customer!

Happy holidays from Bartlett Tree Experts!

Pruning improves the appearance of trees and also helps encourage the development of a desirable, stable form. https://www.bartlett.com/tips/winter-pruning.cfm

Fall is for fertilization! Autumn is an ideal time for soil work to be completed because two vital needs can be addressed at once: (1) nutrients aren’t needed for new foliage growth in autumn or winter so trees and shrubs can instead use those nutrients for root development and (2) excess nutrients can be stored so that they are immediately available when the next season’s spring growth begins.

"How old is that tree?"

This year for Black Friday, consider adding some dramatic black plants to your garden! https://balconygardenweb.com/20-black-flowers-and-plants-t/

Turn your garden into a naturehood by growing local native plants. Adding just a few California native plants can make a difference for local wildlife. Wonderin...g how to get started? This Thursday, tune in to our Naturehood Gardening 101 webinar where CNPS expert horticulture team will guide you through the basics for adding native plants with habitat power to your home landscape. We'll also chat with three Californians - a renter, new homeowner and established gardener - who will share their diverse experiences growing California native plants. Anyone can do it! Register here: http://bit.ly/naturehoodwebinar Photo of Stefanie Pruege's garden. She is a CNPS Garden Ambassador who has transformed the place she calls home into a refuge for local wildlife through local native plants. #NaturehoodGardening #HabitatGardening #CaliforniaNativePlants

Check out some of the changing leaves just getting started

This was a pink rot treatment we had done for a client. There is an amazing difference in the before and after.

The science behind why leaves change color

We do love our trees!

These pictures were taken by one of our local Arborist Representatives, Richard McLeod and his loved one on their camping trip to Sequoia National Park Aug 2020. FunFact: The most massive tree in the world - the General Sherman Tree - is located in the Giant Forest in Sequoia National Park. The majority of Sequoia National Park, much like Kings Canyon National Park, is only accessible on horseback or on foot. 84% of Sequoia National Parks is designated as wilderness.

The forest green of Redwood National and State Parks (NPS) in California is so calming. From a seed no bigger than one from a tomato, a coast redwood may grow to a height of over 350 feet and have a width of 22 feet at its base. It takes very specific conditions for these amazing trees to thrive and believe it or not, in this narrow zone where land meets sea, salt-laden winds, cold fog-shrouded days and steep slopes can conspire against plants. Resistance to fire and insects helps, and so does teamwork. Redwoods grow close to the coast, but they and the firs and ferns that grow around them are helped by a community of spruces and scrubs that buffer them from the ocean's salt. These majestic plants are truly miraculous. Photo by S. Krause, National Park Service.
