Thank You Garden Hosts, Volunteers, Sponsors & Guests!

by Robin McKillop

The Marin-Friendly Garden tour was a huge success with over 600 guests making 2,200 visits to nine diverse gardens on Saturday, May 18. Gardens featured native plants, edibles, rainwater catchment, smart irrigation, wildlife habitat, salvaged materials and more. In addition to strolling through these inspiring gardens, guests had the opportunity to attend on-site presentations by local experts on rainwater harvesting, defensible space and gardening with California natives. We hope the tour inspires visitors to embrace gardening practices that are easier on the environment, in particular ones that conserve and protect our precious water resources.

The garden tour was made possible by the generosity and talent of our host gardeners who shared their amazing gardens and vast knowledge with all of us on tour day. Thank you host gardeners for going above and beyond! Also, thanks to all of the volunteers who donated their time to make this tour possible. Many of these volunteers have been supporting MMWD garden tours for several years, while others just joined. We also owe a debt of gratitude to our sponsors for helping to make this tour possible:

The Urban Farmer Store
Bayside Garden Center
Marin Art and Garden Center
Marizco Landscape Management
O’Donnell’s Fairfax Nursery
Point Tiburon Plaza
U.C. Cooperative Extension Master Gardeners

Last, but not least, we would like to thank everyone who attended. We hope you enjoyed the tour as much as we did!

Garden Tour Sneak Preview: Going Native

by Greg Van Trump

Registration is still open for the 2013 Marin-Friendly Garden Tour, scheduled for Saturday, May 18, from 10:00 a.m. to 4:00 p.m. It only takes a minute to sign up using our online registration system, and there’s no charge to attend! We hope you can join us.

The 2013 tour features nine inspiring gardens that showcase a variety of environmentally friendly practices, ranging from conserving water to creating wildlife habitat. Here’s a sneak preview of one of the gardens on this year’s tour.

To find California native species in a garden is fairly common in Marin, but a garden planted entirely with California natives is an exciting and rare find. Sectioned into riparian, woodland, meadow and chaparral plant communities, this hillside garden offers an easy way to experience a variety of native plant species at one convenient location. As you stroll along the crushed lava rock path that leads through the property, you will pass through riparian and woodland habitats, complete with a dry creek bed wandering down the side of the house and then exiting under two volunteer California live oaks. The path continues through a sedge transition meadow then across a dry meadow featuring drought-tolerant grasses, perennials, a variety of annual wildflowers and showy red and pink clarkias. Don’t worry if you are not keen on plant identification as nearly all the plants are labeled. And finally, a variety of chaparral species rounds out this wonderful exhibit of California natives. The dry meadow, chaparral and hedgerow areas are no longer watered, flourishing only on rainfall provided by Mother Nature. This garden is certified by the National Wildlife Federation as a Wildlife Habitat Garden and by the Bay-Friendly Coalition.

Consider planning your visit to this garden around noon, when the property owner will discuss “Gardening with California Natives”—one of three free garden talks included as part of the tour.

Creative Thinking

by Charlene Burgi

When I get a new idea, I head out to the workshop and barn. Stored treasures are found in and around those buildings. Most items are intended for purposes other than to be used in the garden, but it is where I go to let my imagination run wild! For example, behind the shop are scraps of lumber salvaged from building our home. Jack uses the wood for fueling the wood-burning stove in his shop, but I envision those scraps turned into needed raised planters. Sitting in the barn are old wood-framed windows rescued from garage sales, which could become cold frames to house and protect seedlings. Various lengths and diameters of PVC are always at the ready in case of underground breaks or leaks, but I see future frames for cages built to protect the blueberries and raspberries from our neighboring deer, squirrels, rabbits and birds.

Garden shed

Salvage can be found everywhere. My garden shed was a single-car garage that we rescued from a local rancher who wanted to raze it. Jack backed his trailer up to the structure and managed to lift the building up high enough to drive it over the dirt roads to home. I must admit we looked like the Beverly Hillbillies driving down the road, but I had a vision and purpose! With the shed in place, I now dream of using some of those old windows and turning the structure into my “play house.” Currently there is a dirt floor, yet as I look around I see unused chipped pavers, broken bricks and clay pots, and assorted flat rocks on the property. A mosaic floor will add to that shabby chic garden shed that is already filled with garden tools, assorted pots, bags of soil, and all the toys needed for a gardener’s delight. Visions of wisteria, sweet peas and morning glory grow in containers and soon promise to frame the exterior.

A few years ago a student in my irrigation class shared pictures of his rubble walls. He used old wine bottles, broken concrete and miscellaneous rocks, then filled the voids with various low-water-using plants such as creeping thyme, succulents, campanula and saponaria. The outcome was stunning. Recently, I saw another gardener who had built her raised planter beds out of wine bottles set three to four deep on end with the bottle necks buried in the soil. In both cases using the materials at hand meant money saved and less to the landfill.

Even if you aren’t planning a project as elaborate as these, there are many opportunities to reuse and recycle. Think of all the ideas shared in past blog posts. We’ve use cardboard for sheet mulching, clear gallon jugs with the bottoms cut off to protect tender new plants, popsicle sticks to identify seedlings, saved toilet paper and paper towel rolls acting as organic mini planters to start seed, and compost bins made of pallets to house rich organic material destined to go back into the garden.

Our salvaging doesn’t stop there. Jack and I need to build a protective fence around the vegetable garden, and my eyes drift to the old fence posts saved off the property from years past. Stacking them in a crisscross pattern will enhance the garden. Wire mesh will line the back side to prevent rabbits from entering, and I can already visualize the seedling peas and cucumbers clambering up the wire mesh for easy picking.

Let your creative juices flow. Are there items you can rescue and repurpose? Do you have rubble or waste that can be transformed into something delightful? Please share those ideas with the rest of the readers.

A coop built of salvaged fencing material is home to these chickens. Check it out on the Marin-Friendly Garden Tour May 18.

If you are wondering what ideas you can utilize, don’t miss MMWD’s free Marin-Friendly Garden Tour on Saturday, May 18. The self-guided tour is from 10:00 a.m. to 4:00 p.m. Register online and we will email you the Garden Guide with addresses and driving directions. Several of the featured gardens make use of salvaged and repurposed materials. The tour might offer new ideas and find you rescuing trash to create a unique landscape that captures the interest of those entering your garden gate.

Why is Marin-Friendly Gardening Important?

by Robin McKillop

Perhaps the interconnectedness of gardens, watersheds and people is nowhere more apparent than in Marin. Almost all of our water supply comes from local rainfall, collected from local watershed lands and stored in local reservoirs. Unlike most Californians, people in Marin live in the same watersheds that supply our water, witnessing first-hand the impacts of our activities on our local waterways. It’s apparent that what we do in our gardens has a direct impact on water quality in our local creeks and waterways, and on the plants and animals living here.

Marin Municipal Water District watershed lands total over 21,000 acres, and are home to over 400 species of animals and 900 species of plants, including many rare, threatened and endangered species. The watershed comprises only 0.2 percent of the area of California and five percent of Marin County, yet 15 percent of the state’s native plant species and 50 percent of the county’s can be found here. Lagunitas Creek, which begins above district reservoirs near the peak of Mt. Tamalpais on land owned by MMWD, is a spawning and rearing ground for endangered coho salmon and steelhead trout. It supports one of the best populations of coho salmon in California.

In addition to its critical role in nature, water plays a central role in our gardens. All plants need water to survive, but different plants need different amounts of water. Many plants that grow in Marin naturally have adaptations that allow them to survive through our hot, dry summers without any supplemental irrigation. Other plants, like thirsty lawns, require constant watering and maintenance. In Marin, a lawn the size of a tennis court needs about 400 gallons of water per day in July to remain healthy. That’s equivalent to having 16 people each taking 10-minute showers at your house every day! When you consider that irrigation systems are never 100 percent efficient, even more water is needed. Much of this water is wasted due to runoff, which travels into local waterways carrying harmful chemicals and other pollutants with it.

Marin-Friendly gardening is grounded in the notion that there’s a better way to achieve productive, beautiful gardens and minimize our impact on the environment. Marin-Friendly gardens use practices sensitive to our local environment, particularly ones that conserve and protect our precious water resources.

The Evolution of Gardens

by Charlene Burgi

A few years ago I planted Aztec lilies in Lassen County to see how they would perform in extreme weather conditions. That early garden was planted primarily with bulbs that could sustain themselves without the need for irrigation or critter control since we were not living there yet. The following summer provided a modest display of color to the front garden. I felt like the choices I made were a success despite lacking the framework I knew was needed in the course of the garden’s evolution.

A beautiful garden is not typically rolled out in a weekend. It involves living with the space and takes years to plan, experiment, coordinate, add and subtract. During that evolution, plants grow, can be moved or removed. In time, gardens take form and shape. A well-planned garden provides color, texture and interest at various times of the year. The design should draw you in to probe the mystery of hidden fragrances, explore follies, and discover the intricacy of exquisite flowers. Plant choices need to add to the form of a garden while also serving the function of attracting birds, butterflies and beneficial insects. The sustainable practices for maintaining a healthy garden must be considered during the development.

Part of the evolution requires thought about how the space will be utilized. Is the garden a place for entertaining, growing food, playing or meditating? Would you like to grow natives or consider rainwater catchment systems? Will there be an area for chickens, garden shed or greenhouse? It could be a combination of all these elements and designed with rooms and pathways meandering throughout.

Are you stuck on the evolution of your garden? Is there a trouble spot or tired portion of the landscape that needs to be spruced up? Perhaps you are starting with a fresh blank slate and looking for ideas. On Saturday, May 18, the Marin Municipal Water District invites you to explore nine beautiful and inspiring gardens on the Marin-Friendly Garden Tour. This FREE, self-guided tour runs 10:00 a.m. to 4:00 p.m. and will also include “garden talks” by local experts. Register at marinfriendly.brownpapertickets.com, and we will email you the Garden Guide, which provides information about each garden as well as addresses and driving directions. Register by May 1 to be automatically entered into a drawing to win a Marin-Friendly prize.

Believe it or not, in their past lives many of the gardens on the tour were dull lawn, invasive weeds or even concrete. They certainly have been transformed over time. Each garden is unique. Each garden offers various ideas that may stimulate creative changes. Learn about environmentally friendly garden practices and put these ideas to work for you. Let the gardens evolve!

Another Sneak Preview: Marin-Friendly Garden Tour

by Craig Lauridsen

Registration is still open for the 2013 Marin-Friendly Garden Tour, scheduled for Saturday, May 18, from 10 a.m. to 4 p.m. It only takes a minute to sign up using our online registration system, and there’s no charge to attend! Register by May 1 to be automatically entered into a drawing to win a Marin-Friendly prize! We hope you can join us.

The 2013 tour features nine inspiring gardens that showcase a variety of environmentally friendly practices, ranging from conserving water to creating wildlife habitat. Here’s a sneak preview of one of the gardens on this year’s tour.

There are so many reasons to visit this garden. The front yard has a collection of towering redwoods and an impressive valley oak that have watched the neighborhood mature for over 100 years. When you enter the backyard, it’s hard to believe that for 40 long years the entire space was covered in cement and a swimming pool. This all changed when new owners purchased the home in 2010. They worked with a landscape professional and designed the backyard to be drought-tolerant and wildlife-friendly, with mostly native plantings, and a vegetable and herb garden. Stepping-stone pathways connect three small patios, and artwork is peppered into the landscape to add color and character. One corner of the backyard features two raised beds for a seasonal vegetable garden and a wire trellis on the fence encouraging two young kiwi plans to grow. Soil is kept healthy through the use of a compost bin. An onsite well is used for irrigation, and the owners carefully manage their water by using drip irrigation and a self-adjusting irrigation controller.

Welcome Sprouting Scientists to Lake Lagunitas!

by Jaimie Baxter

Do you love learning about Mt. Tamalpais and its plants and animals? Explore the northern side of the mountain, participate in fun activities and become a Citizen Scientist.

The Marin Municipal Water District believes that exposing youth to real scientific projects and the outdoors is the best way to instill environmental stewardship. And, lucky for us, the California Academy of Sciences does too! Citizen science is a big part of what we do on Mt. Tamalpais, so we welcome you to join us for a very special event on the first Saturday of May. What is Citizen science? In essence, it is “the study of nature by the people who live in it, which means YOU!” We encourage you and your families to join us in being environmental stewards to Mt. Tamalpais.

In 2012, the Marin Municipal Water District and the California Academy of Sciences teamed up to conduct a Botanical Bioblitz—a large scale  survey of every single plant species on the Mt. Tamalpais Watershed. This multi-year effort involves citizens, botanists, nature photographers and students alike. Click here for more information about this project.

On Saturday, May 4, from 10:00 a.m. – 2:00 p.m., MMWD and the California Academy of Sciences are hosting a “Sprouting Scientist” event at Lake Lagunitas in Fairfax. Both organizations will be on top of the dam at Lake Lagunitas to facilitate family-friendly, hands-on, science-based activities. Our Botanical Bioblitz, a real scientific project, is occurring on the same day, so families can come join the fun of collecting and recording all the plant species in the surrounding area. Come find out what it means to be a Citizen Scientist! Prizes will be handed out to all families who participate. The event is free, although the usual parking fee of $8.00 per vehicle still applies.

For more information, visit our website or contact volunteerprogram@marinwater.org or (415) 945-1128.

Spring Wildflowers

by Charlene Burgi

Creeping phlox

Spring is in the air. One minute the sun is warming the earth, and the next minute we are donning raincoats and grabbing umbrellas. While the weather is unpredictable, springtime consistently produces some of the most glorious wildflowers to be seen.

As I drove to Marin this week, I noticed sweet drifts of pink creeping phlox showing up along the roadside that, not so long ago, was covered in snow. Brilliant orange poppies spun their gold through meadows and the redbud shrubs burst into color as if vying for attention. New growth of green from deciduous trees seemed to dance through the forest of conifers still bearing the scars of winter storms.

Sagebrush buttercup

I love spring. Everything seems to come alive. During one of those rare sky-blue warm days in March, I grabbed my camera and set out for a walk around the ranch hoping to find some wildlife to capture digitally. While nothing furry appeared before my lens, I did come across the most beautiful glossy yellow wildflowers. I was stunned by the intense color and couldn’t walk by without capturing their loveliness to share with you. I soon learned that the sagebrush buttercup, Ranunculus glaberrimus, is listed as a California native in the northeast part of the state. Amazingly, very few sightings are registered on the CalFlora website. Even more amazing is there is another buttercup, glossy buttercup, that looks much like the sagebrush buttercup but is considered a nocuous weed in many states. Research revealed subtle differences between the two, and I was greatly relieved that I wasn’t promoting an invasive weed!

My research on this little yellow beauty made me think about people collecting seeds from wildflowers. I wondered how many research their discoveries prior to gathering and sowing their finds. Many people new to Marin see the gorgeous yellow blooming bushes during this time of year. They frequent nurseries asking for the plants, not realizing those bushes are invasive Scotch and French brooms we are fighting to eradicate on the Mt. Tamalpais Watershed and in other parts of Marin. Once again, it is important to know your plants before propagating them!

Speaking of the Mt. Tamalpais Watershed, there are many wonderful spots to hike and see wildflowers this time of year. Take a stroll around Lake Lagunitas or explore the different habitats along Rocky Ridge. I hear that the iris and lupines are particularly beautiful this year! This is also the time of year to explore Days Island in Novato where native rockrose is found exclusively along with one other place in the Mediterranean. Those seeds are collected for propagation purposes. And the rockrose is a sure winner for planting in native gardens. (As a reminder, seed collecting is not permitted on the Mt. Tamalpais Watershed.)

If you are interested in adding native plants to your garden, don’t miss the Marin California Native Plant Society’s Annual Spring Plant Sale tomorrow, April 13, from 10:00 a.m. – 3:00 p.m. at Green Point Nursery in Novato. While visiting Marin, I spoke to staff members at the College of Marin and learned the Indian Valley Organic Farm & Garden also has its Spring Plant Sale coming up next weekend, April 20 – 21. In addition to native plants, they will be selling many organic vegetable starts. This is the perfect opportunity to collect healthy native and vegetable starter plants that thrive in the garden. Will I see you there?

Celebrate Our Planet at Earth Day Marin on April 21

by Trang Bach

Can you imagine that before 1970 it was perfectly legal to dump tons of toxic waste into a nearby stream? There was no legislation to prevent such acts or to stop big companies from pumping dark clouds of fumes into the air. Concerned about Earth’s fate, Senator Gaylord Nelson of Wisconsin decided to create Earth Day as a way to celebrate planet Earth while bringing attention to the environment. His purpose was to rally people to improve our environment and preserve our natural resources. On April 22, 1970, an estimated 20 million people participated in Earth Day. Since then, Earth Day has become a global event and is celebrated in over 192 countries each year. Millions of people continue to come together to celebrate the earth and promote sustainable activities because of the foresight of Senator Nelson.

This year, Earth Day Marin 2013 Festival will take place on Sunday, April 21, from 11:00 a.m. to 5:00 p.m. at Redwood High School in Larkspur. It will be a fun, free, family-friendly event and a day of action on climate change solutions. There will be speakers, comedy, music, local organic food and hands-on activities, including Sea Party, a carnival for kids developed by Greenwood School 7th and 8th graders. This event will take place rain or shine. For more information visit earthdaymarin.org.

MMWD will have a booth at Earth Day Marin. Stop by and visit and we’ll give you some tips on water conservation and tell you about our upcoming Marin-Friendly Garden Tour on May 18. Let’s conserve and preserve our lovely planet!
