The Sierra snowpack, which is responsible for more than 60 percent of California’s water, won’t likely make it back to its pre-drought levels until 2019, scientists said in a study published this week, dashing the hopes of those who believed one extremely wet El Niño year could alleviate the state’s water crisis.
In the study, published Tuesday in a journal of the American Geophysical Union, scientists from UCLA concluded that there is a more than 70 percent chance that the Sierra snowpack will take three years to make it back to average levels, after reaching a historic low in March 2015. Read More...
How to get your landscape through summer
- without turning up the water!
While native and climate-adapted gardens may take summer in stride, the long, dry days of July and August and late-day heat of September can be stressful on our non-native landscapes. This summer as we all check our thermometers and key-in our controller schedules, we'd like to revisit a few key points to help keep our landscapes beautiful, healthy, and safe!
WHAT CAN I DO TO HELP MY LAWN?
Did you know that a traditional, green, cool-season turf-lawn requires the most water in the landscape (the only other culprit that comes close is evaporation from an uncovered pool or spa), especially in the summer. But letting your lawn "go brown" is not necessarily the best solution for our landscape, it's soil health, and it's longterm aesthetic potential. We'd like to share a few tips to keeping your existing lawn looking good!
You can mow less oftento keep it green! A longer lawn has more surface area for photosynthesis (meaning a more extensive root system that's more efficient at absorbing water). A longer lawn keeps soil temperatures cooler and reduces evaporation, and has increased moisture reserves in root and leaf tissue. A longer lawn is a more drought-resiliant lawn!
Apply a bio-char soil amendment. One application lasts a lifetime, and will increase your lawns capacity to retain water, effectively reducing your watering needs. Try locally manufactured Sonoma Biochar, orPacific Bio-char, CoolTerra.
Lawns that have been pampered can still thrive on a lot less water, but may need time to grow more extensive root systems. Over the next few weeks, gradually reduce the amount of times you water... once a week is more than enough for many lawns to survive the summer heat until fall rains come.
WHAT CAN I DO FOR THE PERENNIAL BEDS?
MULCH, MULCH, MULCH!This is by far the easiest, least expensive, and most drought-friendly way to help your landscape conserve water.
Apply clean, weed-free, well-composted organic mulch made from recycled or post-consumer materials.
Avoid synthetic products such as rubber mulch, landscape fabric, or other heat retaining materials such as lava rock, large stones or black-dyed wood chips.
Don't remove what's there - cover it with a simple, good looking 2-4" layer of mulch that will reduce water loss from your soil from evaporation, stabilize soil temperature, and actually improve your soil's structure, health and water absorption capacity.
By letting the mulch and passing time create a vibrant soil ecosystem, you'll be increasing your property value and creating a healthy landscape to plant into when you're ready to invest in new landscape plants.
We recommend planting in the fall, when the seasonal precipitation will help new plants get established without having to rely on municipal water or worry about irrigation regulations.
Trees provide shade and keep soil temperatures cool, they create habitat and oxygen, sequester carbon, and reduce air pollution. They are expensive to replace and contribute the most to property value. Here are a few great links to information on keeping your trees healthy while trying to conserve water in your landscape.
THIS ONLINE ARTICLEfrom Sunset Magazine highlights some drought-centric tree-care tips, as well as other gardening and landscaping advice.
The Sacramento Tree Foundation put out THIS PUBLICATIONwith lots of great info on helping both young and old trees survive the drought.
They've also linked to an easy-to-read INFOGRAPHIC from the California Urban Forests Council.
It doesn’t take a mighty wind or perilous winter weather to cause branches to break and cause damage to your home, car and yes even you, family or neighbors... CLICK HERE for the full blog post on "summer limb drop" from Cagwin & Dorward.
Pruning is the best way to reduce the chances of Summer Limb Drop, not to mention that regular maintenance helps reduce the chances of damage from high winds or winter storms. I recommend weight reduction for the long lateral limbs.
Water your trees infrequently with heavy soakings. This promotes healthy root systems and improves the trees vascular system functions.
Disease and insect prevention/control helps reduce stress during the long California summers.
Heritage trees or large trees located near homes or high traffic areas should be inspected annually.
Lastly, we'd like to leave you with a few more tidbits to help you care for your trees this summer:
Always WATER EARLY IN THE MORNING, while trees are evapotranspiring, before it gets too hot. Tree roots DO NOT absorb water during the hottest parts of the day.
DO NOT FERTILIZE drought-stressed trees - they are unable to absorb the nutrients and fertilization can damage their root systems.
For tree inspections & pruning, always hire a tree-care company that employs CERTIFIED ARBORISTS.
SFLA NEWS FROM THE OFFICE!!
Flowers are blooming, bees are buzzing, and the office is bustling! We've got two new faces helping things hummm along this summer. Our new summer intern Ian, a Merritt College Landscape Architecture student, is keeping busy helping us get ready for the 2017 Bringing Back the Native's Tour. Meanwhile, Mason is putting his skills to work helping with some much needed digital housekeeping before heading back to the University of Washington in Seattle this fall. Thanks guys!

THIS MONTH'S NATIVE PLANT HIGHLIGHT

California Native Buckwheats (Eriogonum)
Summer is the time for Buckwheats
Buckwheats are low water-use, evergreen perennials, and pillars of their plant community. They are some of the most popular nectar sources for butterflies and other pollinators, and great nectaries for many insect predators. One plant can have hundreds of insects interacting with it at once - bringing life and vibrancy to our gardens.
Their colorful blooms last all summer, turning a rusty, chocolatey brown in the fall. They are stunning planted with native sages, around boulders, and against brickwork. Most do very well in interior gardens - only needing part-shade to survive the hot, dry summers. Plant with native Penstemons and Epilobiums for garden color April - December.
