atrium watered with graywaterThe 50 or so plants in Maya M.’s beautiful atrium have never tasted pure drinking water. Instead, she keeps them happy and hydrated with buckets of lightly used water.

Though people often associate graywater with laundry-to-landscape or more elaborate, professionally installed systems, getting started with graywater can be as simple as buying a few good buckets. Graywater collected in a shower or bathroom sink bucket works well for toilet flushing and is fine for watering landscape plants and fruit trees. (Just be sure to choose a biodegradable soap, make sure graywater infiltrates into the soil and doesn’t pool or run off, and avoid letting graywater come into contact with any plant parts you plan to eat.)

In addition to being a proud member of the “bucket brigade,” Maya also is a big advocate of “stop the disposal” containers; since running the disposal uses a lot of water and energy, diverting fruit and vegetable trimmings to a handy juice container, lidded bowl, or basket and then to the compost pile is a simple way to save.

Maya learned the value of water growing up in the Netherlands during the war. When the bomb sirens sounded, the water and gas companies would at times turn off the utilities. Her job was to fill the bathtub so her family would have water during and after the air raids.

She still views water as most precious. She hand waters her garden to ensure plants get just what they need and is a proponent of saying goodbye to unwanted lawns. “To be green we have to love beige and let our lawns go dormant,” she says.

As her experience shows, being green also means loving gray.

(This is part three of our garden expert Charlene’s trip to Italy. Read the first and second installments.)

A day exploring Florence and visiting the leaning tower of Pisa completed our stay in Tuscany. Liguria was our next destination, where we found the five picturesque fishing villages along the Italian Mediterranean otherwise known as Cinque Terre. We were pleasantly surprised as we headed out of the Tuscan region as we drove under an unmarked, ancient aqueduct still carrying water to regions that I imagined to be nearby.

To the north loomed mountain ranges that I thought to be covered in snow. We soon realized the glistening white of the mountains near Carrara were quarries of marble that Michelangelo once traversed searching for the perfect piece to create artwork such as his sculpture of David.

As we continued north, the roads wound like a lazy snake through the wildflower-covered hills. Below lay the clear waters of the Mediterranean. We soon found the time allotted to explore this region was too short. We only had two nights and a full day to see all that we could. Transportation to these little fishing villages required taking a train, a boat, or hiking, so we opted to take in only two of the five villages. We were thankful for the ability to reach the jeweled towns, for it was only in 1926 that roads were cut into the hillside to reach them. Otherwise, they could only be reached by boat!

We arrived during the weekend and the tiny communities were mobbed with tourists. We walked along the busy, narrow streets where I noticed people milling about a grotto. Upon closer inspection, we saw the grotto featured an open spigot where the drinking water flowed freely. People clamored to the precious liquid to refill their water bottles, wash their hands, or cool their brow.

The sight of water freely flowing unnerved the water conservationist in me. It was an assault to my senses! The paradox is, while the water escaped into the basin below, every restaurant in Italy charged for a bottle of drinking water—asking with or without “gas” (known to us as sparkling water). I wondered why the restaurants in Marin don’t exercise this practice with water being such a precious commodity—after all, I now understand that it is so European! Would that practice ever catch on?

Bougainvillea

After recovering from the grotto, we traversed the breadth and width of the beautiful beaches and tiny streets that were covered with magnificent flora. Bougainvillea, lantana, ivy geraniums, and so much more filled the grounds of exquisite estates that faced the Mediterranean.

As we walked along one path, Lynette asked me to identify a plant. I had never seen it before but fell in love with the delicate flower. Guido and Paulo, friends of Lynette who live in Italy and met us at Cinque Terre, quickly pulled out their smart phones to identify the plant as Capparis spinosa, otherwise known as capers—the very accoutrement that we use in cooking! I couldn’t wait to find out more about this plant. It was, in fact, one of the first things I investigated upon my return. To my surprise, Capparis will grow in Marin! Why has this beauty eluded me, and would the nurseries be able to find this deciduous perennial bush also known as Flinder’s rose? True to its Mediterranean origin, it needs very little water, requires fast draining soil, but tolerates poor soil. This all made perfect sense as the plant we saw was growing in a rock wall. It can act as a groundcover or trail over walls. What a treasure!

May I encourage you to also explore using this plant in your landscape? The buds can be pickled if you use capers in your recipes. Just taking in the beauty of the delicate flowers from late spring through summer would bring enough joy as you watch the flowers open in the morning and close as evening approaches.

I fell asleep that night wondering if capers could survive in our little greenhouse in Lassen and missing the Mediterranean climate of Marin where I knew this plant could thrive and enhance any garden.

MMWD’s water production for the period February-June 2014 was 15% lower than production for the same period in 2013. Many thanks are due to district customers for quickly heeding the MMWD Board of Directors’ January 21 call for voluntary reductions in water use. The board took that action just days after Governor Jerry Brown requested statewide voluntary reductions in water use.

The 2013-14 rainfall year ended on June 30 with a total of 33.4 inches, which is approximately 64% of the long-term annual average. By contrast, total reservoir storage at the end of the 2013-14 rainfall year was 90% of average. The near-normal storage levels are due to unusually high rainfall in February, customer conservation efforts, and higher Russian River water deliveries.

Here are the current water statistics:

Reservoir Levels: As of July 22, reservoir storage is 57,524 acre-feet,* or 72.3% of capacity. The average for this date is 63,144 acre-feet, or 79.36% of capacity. Total capacity is 79,566 acre-feet.

Rainfall: Rainfall this year to date (July 1-July 22) is 0.03 inches. Average for the same period is 0.04 inches.

Water Use: Water use for the week of June 14-20 averaged 28.29 million gallons per day, compared to 31.38 million gallons per day for the same week last year.

Supply Source: Last week we averaged 20.76 million gallons per day from our reservoirs and 7.53 million gallons per day from the Russian River.

Creek Releases: During the month of June 2014 MMWD released 200 million gallons, or a total of 614 acre-feet, into Lagunitas and Walker creeks in west Marin.

Water use and reservoir figures can be found on the Water Watch page of our website.

(This is part two of Charlene’s trip to Italy. Read the first installment here.)

Central and northern Italy’s flora was amazing. The dense, lush vegetation filled every inch that didn’t have a structure or wasn’t cultivated for crops (primarily grapes and olive trees in the Tuscan region). The narrow, twisting, hilly roads in Greve guided us through forests thick with brambles, vines, and wildflowers. Each turn in the road surprised us with charming, tiny villages as we made our way to the Autostrada that paved the way to the ancient walled cities of Tuscany.

Stone steps in Italy

One of thousands of steps

For several days, San Gimignano, Siena, Montepulciano, Pienza, Montalcino, Monteriggioni, and Lucca found my daughter Lynette, her husband Jeff, and my son Randy coaxing me up the steep roads, and what seemed like thousands of steps, to reach the heart and plazas of these walled medieval towns. All the Stair Masters of the world could not have prepared me for this grueling exercise! Though my calves were screaming, the desire to explore drove me on to find the artifacts and ancient art I had read about. In every plaza we found a well covered with a metal grate. The steps leading up to each well provided seating for the weary tourist.

What I didn’t expect was the abundance of window boxes crammed with color that brightened up the ancient structures from the 12th and 13th centuries. Within these ancient cities, all the vegetation was in containers. Repeatedly, star jasmine seemed to be the “star” as its scent filled the air. Despite the size of the plants, I was impressed that all flourished so well in containers. One restaurant even created an outdoor covered arbor using containers of grape vines and, you guessed it, star jasmine to provide shade for the diners underneath.

The stone walls of the cities sprouted beautiful foliage that accented the patterns formed by stone masons of yesteryear. The fortress walls angled back toward the center of the town. Even though the stone collected the heat from the summer sun, rain could easily find its way into the crevices to irrigate the tenacious plants.

And rain it did! While in Pienza, Randy and I ducked into the Palazzo Piccolomini, the former papal palace, to find an open roof that allowed rain to collect in the marble-covered room below. Indoor plants of all types prospered in this wealthy environment. Upon our return to the car, we entered a beautiful park where familiar Cotinus coggygria (smoketree) was in full bloom, but sporting white panicles instead of the familiar smokey, pinkish-purple that I know. At that point, the sky opened up and we were grateful for the canopy of trees in the park acting as a giant umbrella for these ill-prepared tourists!

If conditions are right, plants will thrive. This knowledge was driven home to me over and over again as I witnessed the beauty around me abounding in containers, crevices, and other harsh conditions. It drove home the point of planting native for maximum effectiveness. Year-round rain in Tuscany may increase gardening options without the need of irrigation, but the same principle still applies here at home.

Having lived through three Marin County droughts, MMWD customer Anne Layzer has become an expert at saving water—even while maintaining a 2,000-square-foot vegetable garden and several smaller flower beds. Her favorite advice for conserving water in the garden? Compost.

Many people think of composting as a way to nourish plants and reduce waste by recycling plant and vegetable trimmings back into the garden. But adding compost to your garden also saves water by building healthier, more sponge-like soil that better absorbs and holds onto moisture. Plants growing in amended soil fare better in drought conditions. And of course by composting kitchen scraps rather than sending them down the garbage disposal, you’ll also save the water and energy needed to operate the disposal unit.

Compost piles

Anne’s backyard composting operation

You can start composting on a small scale and work your way up to an elaborate composting operation like Anne’s, which she describes as a central feature of her garden and household recycling program. Her backyard piles have a diverse diet that includes food scraps, leaves, shredded paper, and grape skins from a wine-making neighbor. Even weeds aren’t unwelcome in her garden—they’re more fodder for the pile.

Anne jokes that she doesn’t know whether she has a compost pile because she has a garden or a garden because she has a compost pile. As her daughter says, “Neither: They are one.”

Bougainvillea

Bougainvillea

As I looked around my garden this past weekend, I felt myself sigh in both satisfaction and a little relief. No doubt summertime is here and the plants in my north-facing garden are enjoying the warmer weather and longer days as much as I am! The star jasmine that turn pitifully bare every winter have resurrected themselves once again, and my bougainvillea is back and bigger than ever, spilling its maroon blossoms wildly over my neighbor’s fence.

As a beginning gardener, this has been my most productive spring yet. In contrast to previous years, almost all of the projects I’ve been working on have yielded good results. I’ve been successfully coaxing two morning glories up a trellis, patiently shaping a small collection of rosemary topiaries, and the petunias I received for my birthday in April are still alive and thriving in the intensifying sun. Surprisingly even the poppy seeds I scattered at the end of May have sprouted and grown!

Maybe it’s safe to say that I’ve finally gotten a handle on how things grow, and it’s likely that working in water conservation has helped. But, as far as I’ve come, I do often find myself still grappling with some of the most basic of gardening concepts. One that I struggled with recently? Roots! What’s so complicated about roots, you ask? Well, let me start by saying that if you’re well-versed in water-wise gardening, you’re surely familiar with the principle of watering deeply, but infrequently to encourage more drought-tolerant plants. If you haven’t heard this before, watering in this manner can create plants with roots that grow more deeply. Not only can plants with deeper, more extensive root systems find water and nutrients in more places, but having roots further away from the surface of the soil means they also stay moist longer and plants don’t dry out as quickly.

Rooting petunia

It was this concept that got me thinking. How deep is “deeply,” exactly? Of course, watering my potted plants has always been easy; I simply water until it comes out the bottom (fool-proof!). But, as I graduated from the simplicities of planter gardening, I began wondering about the tall shrubs that run around the perimeter of my yard. How deep are their roots? And what about trees? Is it both possible and necessary to water their entire roots zones?

Well, what I have found is that plants and trees have portions of their root systems that can, in fact, grow very deep in the soil. You may remember Charlene mentioning in a previous post that some California annuals have roots that reach 20 feet! These deeper roots can serve as structural supports and to find water and nutrients in extreme conditions. Oak trees growing naturally on our watershed, and throughout Marin, typically have taproots that grow deeply for this reason.

However, I was surprised to find out that the vast majority of a plant’s root system is concentrated much closer to the surface than I originally thought. Roughly 80% of a tree’s roots, for example, are concentrated in the top 12 to 36 inches of soil. Quite amazing when you think of how tall trees can get! Roots are confined to this depth, for the most part, because this is where the most oxygen, minerals, and nutrients are readily available. These elements become less and less prevalent as depth increases, and thus roots do, too. Not surprisingly then, watering beyond a depth of 36 inches essentially wastes water and effort.

A great take-away tip that I found from the California Master Gardener Handbook, and one that I now use for hand watering, is the 1-2-3 rule. Water to a depth of one foot for small plants (like annuals and groundcovers), two feet for medium sized plants, and three feet for large shrubs and trees. How long it will take to reach this depth will vary depending on your soil type and the flow of your hose, so some initial experimentation is necessary. A day or so after watering, use a soil probe or a shovel to dig down and to see how far the water has traveled, then adjust accordingly. Consider using this same procedure to check that your irrigation runtimes are sufficient as well.

With this small token of wisdom comes another sigh of relief. So far, gardening has surely been a process for me. It’s been a piecemeal operation with successes, frustrations, a lot of listening to those wiser than me, and most importantly, enjoyment.

The rainfall year ends on June 30 and in all likelihood we will not receive much, if any, additional rain in the remaining few days. Total rainfall at Lake Lagunitas for the rainfall year ending June 30 will top out at around 33.40 inches, which is about 64% of the annual average. This marks the third consecutive year of below average rainfall, and the reservoir storage levels reflect those low numbers.

The current reservoir storage is the lowest it has been for this date since the early 1990s. If not for the ongoing conservation efforts of our customers, and the especially heavy rain in February, we would be in a far worse position than we are today.

The MMWD Board of Directors’ call for 25% voluntary rationing is still in place and current consumption figures show reduced water use. We appreciate everyone’s conservation efforts and we encourage customers to take advantage of the district’s many conservation programs and rebates. Get more information here.

Here are the current water statistics:

Reservoir Levels: As of June 22, reservoir storage is 60,533 acre-feet,* or 76% of capacity. The average for this date is 67,290 acre-feet, or 85% of capacity. Total capacity is 79,566 acre-feet.

Rainfall: Rainfall this fiscal year to date (July 1-June 22) is 33.40 inches. Average for the same period is 52.56 inches.

Water Use: Water use for the week of June 16-22 averaged 28.78 million gallons per day, compared to 32.27 million gallons per day for the same week last year.

Creek Releases: During the month of May 2014, MMWD released 218 million gallons, or a total of 669 acre-feet, into Lagunitas and Walker creeks in west Marin. We release water throughout the year to maintain adequate flows for the fishery per our agreements with the State of California.

Last December, I bought and moved into my first house (my first house!). When I moved, I brought with me a large assortment of container plantings I’d accumulated over the past dozen years or so—pineapple sage, ferns, agastache, salvia, fuchsia, honeysuckle, penstemon, bee balm, and various succulents. Now that I was in my own home and had a “real” yard to work with, I was eager to get my collection of potted plants into the ground where they belonged. But it was mid-winter, I had a seemingly never-ending list of DIY projects inside the house to keep me occupied (which, amazingly, continues to grow), and I knew the plants would be fine until I could find the time to give them a permanent in-ground home.

Save Our Water logoA few months later, just as I was starting to think about digging planting holes and getting the garden in order, a co-worker forwarded me a link to the Save Our Water website. Of particular interest to me was the section “Water-Wise Landscaping Basics,” which provides information on things to keep in mind when creating or maintaining a low water-use landscape. Even though I felt like I had a pretty good handle on water-wise gardening (based on almost 20 years working in water conservation), I found reviewing the site’s list of simple basic principles to be an excellent refresher. It’s easy to overlook the importance of mulch in reducing water use in the garden or to forget to adjust the irrigation schedule as often as one should. However, considering the record low rainfall we received last year, and the annual uncertainty of what future rain may fall, it’s a good idea for each of us to look at what we’re doing in our own gardens and make sure we’re following the basic framework of water-wise gardening.

The following is a slightly abbreviated version of the basic principles from the Save Our Water website:

Appropriate plant selection: Select trees, shrubs, and groundcovers based on their adaptability to your region’s soil and climate.

The right plants for the right soil: Knowing your soil and selecting the right kind of plants for your area is an important part of a water-wise landscape.

Limit your grass: Consider cutting back or eliminating the amount of turf you have at your house.

Efficient irrigation: The greatest waste of outdoor water is applying too much too often.

Mulch is good: Use mulch wherever possible. Mulch conserves water by significantly reducing moisture evaporation from the soil, reduces weed populations, prevents soil compaction, and moderates soil temperatures.

Appropriate maintenance: A well-designed landscape can decrease maintenance by as much as 50% through reduced mowing, once-a-year mulching, elimination of non-California-friendly plants, and more efficient watering techniques.
