"Trees for Tomorrow Start Today" Master Gardener Program Application for San Bernardino County Residents
Applications Now Being Accepted for the University of California Cooperative Extension Master Gardener Program “Trees for Tomorrow Start Today” Project.
University of California Cooperative Extension (UCCE) San Bernardino County is currently recruiting adults (18 and over) who are interested in becoming volunteers for our "Trees for Tomorrow" project. Complete training is provided online through a 50-hour Master Gardener training class taught by subject matter experts. Master Gardener volunteers will provide research-based information on the selection and care of heat, drought, and pest resistant trees and help our non-profit partners and community leaders enhance tree canopy cover in our most vulnerable neighborhoods. (To date, we are proud to have partnered with the Inland Empire Resource Conservation District, CA Climate Action Fellows and many non-profit organizations, communities, ESRI, and others to give away over 600 trees in the last year!)
Applications to become a UCCE Master Gardener volunteer for this project are open through August 31, 2022. UCCE Master Gardener “Trees for Tomorrow” Volunteer Application link: http://ucanr.edu/u.cfm?id=287
Questions about the application process or the volunteer opportunity? Contact UCCE Area Environmental Horticulturist Janet Hartin at email@example.com
Why volunteer for this project? We are facing unprecedented times due to climate change and urban heat islands increasing temperatures in our communities. One of the solutions to a "cooler, greener, tomorrow" is through tree planting and proper selection and long-term care of heat, drought, and pest resistant trees.
Why trees? Shade produced by a single tree can reduce surface temperatures of asphalt and other impervious surfaces by up to 65 degrees F. Trees also lower air temperatures; enhance pollinator and wildlife habitat; absorb pollutants; reduce energy use and related costs (homes, offices, vehicles); beautify neighborhoods; absorb and store carbon dioxide; and provide many other ecosystem and societal benefits.
You can make a difference like never before enhancing tree canopy cover in our neighborhoods. Do you want to learn more about what UCCE Master Gardeners do for San Bernardino County residents and communities, find out what upcoming events they are hosting, or have them answer your horticulture questions Here's your pot of gold: https://mgsb.ucanr.edu/
We are looking forward to hearing from you!

Many previously “welcomed” urban tree species have outlived their stay, becoming invasive and crowding out other plants in our Southern California landscapes. You can help by avoiding planting these trees identified by various sources (including the California Invasive Plant Council) to be too aggressive and habitat/resource-depleting for further planting.
Invasive Trees to Avoid Planting
Athel (Tamarix aphylla)
Black Locust (Robinia pseudoacacia)
Blackwood Acacia (Acacia melanoxylon)
Brazilian Pepper (Schinus terebinthifolius)
Chinaberry (Melia azedarach)
Chinese Tallow Tree (Triadica sebifera)
English Hawthorn (Crataegus monogyna)
Peruvian Pepper Tree (Schinus molle)
Red Gum (Eucalyptus camaldulensis)
Russian Olive (Elaeagnus angustifolia)
Saltcedar (Tamarix ramosissima, T. gallica, T. chinensis)
Silver Wattle (Acacia dealbata)
Smallflower Tamarisk (Tamarix parviflora)
Tasmanian Bluegum (Eucalyptus globulus)
Plant These Instead
They are drought/heat resistant, low maintenance, and have no known significant pest or disease problems and are not currently overplanted). Find other suggestions here: https://www.cal-ipc.org/solutions/prevention/landscaping/dpp/?region=socal

In your landscape, your trees and edibles should come first under drought and water restrictions! If there just isn't enough water to go around, your lawn and flowers should be sacrificed instead. Trees are our most valuable landscape resource and take years to maximize their benefits (shade, cooling, habitat/ecosystem enhancement, carbon dioxide storage, energy conservation, pollution filters, etc.).
Just a few slow, deep waterings with a garden hose away from the trunk and slightly beyond the drip line will keep established trees alive, even during summer. Remember to keep trunks dry!
Here are some other tips:
• Spread and maintain 2-4” of mulch around garden plants and trees (3-4” for wood chips, 2” for pebbles, decomposed gravel, etc.) keeping it a few inches away from tree trunks. (Note: dark colored dyed mulches should be avoided in inland and desert areas due to their high surface temperatures that can > 60 degrees F hotter than living plants and lighter colored mulches.)
• Water early in the morning when soil evaporation is minimal.
• Control weeds. They compete with other plants for water.
• Avoid fertilizing. Nitrogen increases growth and the need for more water.
• Don't plant new plants during the summer when temperatures are highest. Even drought-resistant native and non-native plants need regular watering their first season.
