TreePeople’s Citizen Arborist program is designed to train and produce a trusted network of community members who help keep our trees healthy and thriving. Certified Citizen Arborists are expert volunteers who support their neighborhoods in caring for their local trees. They are on the front lines of growing a healthy urban forest and improving the environment of Los Angeles. Peter Diep, who was recognized with TreePeople’s Volunteer of the Year award, led his first street tree care event right after earning his official Citizen Arborist status in the fall of 2012.… Read more >>
U.S. Forest Service researchers have published compelling evidence* of urban trees’ immense carbon storage capacity. Along with the other many things they do to improve the environment, trees absorb carbon dioxide emissions from a multitude of pollution sources in our cities. “Thus,” the researchers conclude, “urban trees influence local climate, carbon cycles, energy use, and climate change.”
National Arbor Day is April 26. We join our friends at Alliance for Community Trees in the firm belief that reducing atmospheric CO2 is one of the most important functions of the urban forest—and that people can play a big role.… Read more >>
One of our favorite holidays, Earth Day, is on April 22. Close on its heels is Mother’s Day. What better way to celebrate both occasions than by helping to reforest our parks and woodlands? It’s way more meaningful than a bouquet (we think).
From now through April 12, you can make at least two people happy with our special offer on tree dedications. Dedicate a tree to be planted for Earth Day and we’ll give you a 50% discount on a second tree dedicated to your mom–or anyone you love–for Mother’s Day!… Read more >>
Want to grow a fruit tree, but can’t decide which one? Wouldn’t it be great to have more than one type of fruit on a single tree? It’s possible to have this “fruit salad” effect in your backyard with the amazing technique of grafting.
Grafting is the process of splicing a branch or bud from one tree onto another tree. Grafting deciduous trees (trees that lose their leaves in winter) is done in winter when the trees are dormant, or leafless.… Read more >>
Why is the Western redbud (Cercis occidentalis) the best tree ever? Maybe it’s because at this time of year, redbuds are the focal point of any garden lucky enough to have them. This native Californian is a small tree (15–20’ x 15–20’) and does well in most any kind of soil, as long as it is well-drained.
In the late winter and early spring, when most everything else is still dormant and waiting to bud, the red bud has spectacular magenta flowers that are delicate and yet very resilient to cold, wet days.… Read more >>
You may have noticed that some years in Los Angeles County are wetter—or drier—than others. And in wet years you may also have noticed a lot of unfiltered water rushing off paved surfaces, into storm drains, and out to sea carrying whatever pollutants it washes over. So, not only are we losing water that could be captured for local use or returned to the ground for irrigation, we’re failing to clean it up before it enters our waterways.
But did you know that even in times of drought, what little moisture falls from the sky can be harvested and put to use?… Read more >>
“You are never in neutral,” TreePeople founder Andy Lipkis tells environmental leader Huey Johnson, in an interview about how we all affect the environment. “People say [to me], ‘I love what you do because you show that people can make a difference.’” The truth is, people do make a difference, Andy says. And it comes in the form of every step we take, every penny we spend, in all the ways we move through the world.
Growing up in the 1960s in a severely polluted Los Angeles, Andy realized that we have to embrace the notion that even the smallest contribution—whether planting a single tree or shutting off the tap when you brush your teeth—does make a positive difference.… Read more >>
Want to see how an average home in Los Angeles can save almost 100,000 gallons of water per year? Here is TreePeople member and volunteer Valerie Fontaine, converting her yard to a sustainable site. With a simple DIY project, Valerie transformed her garden in a weekend.
Following Part 1 of our tutorial, here are your sheet-mulching FAQs:
Is it really as simple as it sounds? Just put down cardboard or newspaper, dump mulch, keep moist, and wait? Is that it?
Yes.… Read more >>
What is sheet mulching? Just the quickest, easiest way to go from a thirsty, outdated green shag carpet of a landscape to a sustainable garden in about the time it takes to mow the lawn.
Follow these easy steps and you can do what fabulous TreePeople member and volunteer Valerie Fontaine recently did at her house. Once you go green, you’ll never go back.
- Cover the lawn with 1 layer of cardboard or 6 layers of newspaper. Be sure to overlap by at least 6 inches to prevent the grass from growing through.
