Landscape trees provide shade, cool urban heat islands, reduce interior energy use and related costs, provide habitat for pollinators and wildlife, and beautify our communities. They also help clean our environment by absorbing carbon dioxide emitted by vehicles and other producers of fossil fuels.
Taking care of our urban trees is an important way to maximize these benefits. Unfortunately, their average lifespan in our cities is less than 1/4 of their potential due to poor selection and care. You can help enact change and increase the health, longevity and canopy coverage of our urban forests by encouraging your city leaders, local non-profit organizations interested in ‘green cities' arborists, landscape architects, nursery growers, HOAs, and concerned citizens to register for our free ‘Trees for Tomorrow Start Today' workshop (via Zoom) on Tuesday, March 9, 2021 (8:15am – 3pm).
Please reach out to your city leaders and local ‘green industry' professionals to encourage their attendance and participation. While the workshop is free, registration is required through this secure link: http://ucanr.edu/u.cfm?id=264
A bevy of speakers including certified arborists, horticulturists, planners, water district personnel and other non-profit and green industry representatives will discuss the benefits of urban trees; recommended practices for their selection and care; how to avoid hazardous trees that damage property and structures; and share success stories resulting from partnerships through cities, non-profit organizations, the green industry, HOAs, and street tree committees.
A highlight of the workshop will be the opportunity for attendees to participate in breakout sessions that cut across professions and interest groups (city planners, community service directors, arborists, landscape architects, landscapers, water district managers, HOA managers, golf course superintendents, nursery growers, UC master gardeners, concerned citizens, etc.) to enact positive change regarding tree selection and care.
Thank you for sharing this opportunity to help ensure a healthy future for our children's children with your city leaders and decision-makers.
In the meantime, here are some tree care tips to ‘start the conversation' between now and the workshop:
• Select trees that perform well in your climate. The Sunset Western Climate Zone maps are more precise than USDA zones for our warmer climates. Trees should also be selected based on their adaptation to the ‘micro-climate' in each particular landscape, as well (shade, proximity to buildings, space needs below as well as above ground, soil type, water source, etc.)
• Plant trees the same depth they were in their container in holes at least 2-1/2 times wider. Do not add compost or organic matter to the hole. This practice can result in circled roots that never grow laterally out of the confines of the dug hole.
• Remove any tree ties that are cutting into the trunk or branches of your trees. If trees must be staked due to windy conditions, make sure that the ties are loose enough to allow trees to gently flex in the wind. This helps trees develop the necessary lower trunk strength and stability to support the tree as it matures. Over time, you may be able to completely remove the ties and stakes once the lower trunk becomes stronger and self-supporting.
• Keep all plants and mulch several inches away from tree trunks.
• Keep tree trunks dry. They should not come into contact with water from sprinklers or hoses.
• Regularly water newly planted trees but water mature trees infrequently and deeply. Watering too often reduces the level of oxygen in the rootzone and can lead to waterlogged soils prone to crown and root rots. During fall, trees require only about 15% of the water they require in the summer.
• Prune trees only as needed and avoid topping them. Invest in the services of a credentialed and knowledgeable professional to correctly care for your valued trees.

As 2020 comes to a close, I'd like to express my deep appreciation and thanks to all of our UCCE San Bernardino County Master Gardener volunteers who have given the ‘gift of their time' to provide credible information to the gardening public. Even during COVID, they've found creative and safe means to continue reaching the public by converting face-to-face classes and workshops to online opportunities.They've gone above and beyond their expected volunteerism by helping those in need during these difficult times by working with our partners to distribute free seeds, trees, and wattles (for erosion control) and ensuring a happy holiday season for children and adults in need through a gift drive. Through COVID, the UCCE Master Gardeners have maintained their email and phone helplines to help county residents solve their gardening quandaries (linked here) email@example.com and (909)387-2182.
Master Gardener volunteers helped thousands of county residents landscape more sustainably, grow food in home, community, and school gardens, and deepen their appreciation of nature. They:
- Taught classes on drought-resistant landscapes and growing food in home, school, and community gardens
- Hosted ‘Ask the Master Gardener' sessions
- Provided education to community and school gardeners
- Distributed gardening information and answered questions at Farmers' Markets, community fairs and other events
- Answered home gardening questions via email and phone helplines
- Shared gardening information through social media
- Helped promote planting trees to cool urban heat islands in underserved neighborhoods and communities
- Helped take research data on the 'trees for tomorrow' project
- Published the monthly Master Gardener newsletter (thanks Phoebe, Debbie, Maggie, Robin, Sue and contributing authors!)
A special ‘shout out' to our monthly 2020 ‘Spotlight' Master Gardener volunteers for their extraordinary service:
I'd also like to recognize our dozens of non-profit partners including Inland Empire Resource Conservation District and the County of San Bernardino.
And, last but far from least, I'm forever thankful to UCCE San Bernardino County Master Gardener Coordinator Maggie O'Neill whose passion, heart, and expertise keeps the program thriving!
Happy Holidays to All!
