You won’t see it if you’re not looking for it, but you’ll know it was there. No bigger than a baby’s fingernail, the gold-spotted oak borer (GSOB) can devastate a 300-year-old oak tree that has withstood storms and quakes and even the quick and astounding rise of urban pollution in the 20th century. But if individual trees were all that was at stake, the oak borer wouldn’t pose such a threat. The truth is, this invasive pest could wipe out every native oak in California.… Read more >>
Is Los Angeles a desert? Our city gets about 15 inches of rainfall annually, slightly more precipitation than, say, Missoula, Montana (though we have fewer days per year that are considered “wet”). Did you know this is enough to serve a fairly large population and irrigate its urban greenery?
But every time it rains an inch in the city of L.A., 3.8 billion gallons of runoff are sent to sea, sweeping trash, toxins, and bacteria into waterways and polluting our beaches and ocean.… 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 >>
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.
