You can sum up a Carmel garden with one of two descriptions – hot and dry or mild and dry. Closer to the coast the weather is mild year round while further up Carmel Valley it can get pretty toasty.

In either place, the people of Carmel are used to paying close attention to their water consumption. Monterey County water districts have some of the most stringent regulations around.

On a recent trip to this beautiful part of the world, I took the opportunity to study their beautiful low water-use gardens. What makes for a successful garden that doesn?t include a lawn and lush perennial border? Here are some of the plants and strategies that I admired while in Carmel.

Because many homeowners are replacing their lawns with low water-use landscapes a well thought out design is more important than ever.

Stone makes a garden look like it?s part of nature. Granite boulders are one of the go-to choices for accent rocks due to their lower cost and I saw many gardens with beautiful installations using granite. But it was the creamy yellow Carmel stone that caught my eye. It?s used for everything there from retaining walls and steps to veneer for homes.

Carmel stone is a Monterey sedimentary shale and can be found throughout the Santa Lucia mountain range. The best stone colors, however, come from quarries in Monterey County. With beautiful rust, orange, pink and caramel iron oxide striations it?s plentiful and relatively light by rock standards. That?s probably why it was the material of choice for the native Ohlone tribes who built the Carmel Mission.

In addition to the beautiful stonework and boulders in Carmel gardens, plant selection is often unique and bold as well as easy on the water budget. I wasn?t familiar with Globularia sarcophylla ?Blue Eyes? when I first saw it blooming. Covered with hundreds of button size flowers of cream with dark blue centers it really stood out. This showy little Canary Island shrub is very drought tolerant and hardy down to 10 degrees.

Another plant that looked great paired with old fashioned shasta daisies was the medium sized Gold Velvet kangaroo paw. Flowering for most of the year this variety has more resistance to black spot, needs less trimming and is frost tolerant. Plant kangaroo paws in a well mulched garden using chunky bark chips and ensure the crown of the plant is above soil level. Remove older flower stems and cut back foliage every 1-2 years. Kangaroo paw offer drought tolerant color in the garden.

Dramatic purple leafed phormium ?Guardsman? accented one of the gardens. Leucophyllum frutescens ?Los Alamitos? -Texas sage – would complement this phormium. The gray foliage and pink flowers smother this plant in color from summer into fall. Succulents like aeonium ?Sunburst? and echeveria paired with agapanthus and statice made a nice vignette in another garden.

A visit to several nurseries in Carmel Valley shed more light on what customers are buying in these times of drought. One of the smaller leucodendrons called Ebony is a favorite. This bushy compact shrub grows 3 to 4 feet tall and a bit wider with lustrous blackish-purple foliage and burgundy red bracts surrounding the flowers from late winter to summer. One of the great things about this species is its ability to tolerate only occasional to infrequent irrigation once established.

Other low water-use plants featured at the local Carmel nurseries include California native Woolly Blue Curls, the stunning teucrium ?Azureum?, Velour Pink Mexican Bush Sage and Wyn?s Wonder Australian fuchsia.

Lots of awesome gardens, nurseries and plants – so little time. Take some ideas from the people of Carmel and embrace low water-use gardens.

Dry River Beds – Beautiful & Beneficial

With so many people replacing their thirsty lawns with low water-use plants, I?m getting lots of requests for ideas about what to do with all that empty space. The sky?s the limit when you have a blank slate. Let me get you started.

If your old lawn was in the front you might consider putting in a sitting area for a couple of chairs and a bistro table. Use simple crushed gravel or more formal flagstone underfoot and surround the space with a low seat wall to add a bit of privacy.

Adding a dry river bed is another good solution. A dry river bed can slow runoff, spread it out and sink it back into the soil. Connected to a downspout they keep even more rainfall on your own property. If we get the El Nino storms that are predicted this will be a welcome addition to your landscape.

runoff to soak into the ground. Make sure there is a 2% slope from beginning to end to ensure that water is conveyed away from your house to the desired location. Non-woven geotextile fabric is often used underneath the rock.

You can create a depression or rain garden at the end of your dry river bed and plant it with plants that tolerate wet feet in the winter. Both a dry river bed and a rain garden allow water to sink back into the ground. The plants remove pollutants from the runoff from roofs or other impervious surfaces.

A rain garden might be a simple, shallow depression filled with plants that can flourish in both moist and dry conditions. The size and depth will depend on your how much water you need to capture in a winter runoff

Sometimes a dry river bed will receive so much runoff that a dry well or dispersal pit is installed at the end. If you have a high water table or clay soil the water may not always soak in fast enough and an overflow device like this is needed. The goal is to keep water on your own property and not in the street or the neighbors? yard.

There are good looking dry river beds as we?ll as bad looking ones. A quick Google image search will show you what I mean. Your goal is to create something that looks like it belongs right where it is. The plants, the accent rocks, the cobble, the location – all need to work together.

If your property has a natural slope follow the natural terrain if possible. You can install a dry river bed on flat land also by creating a channel for the river bed to follow. Keep in mind that even a dry river bed is more interesting if it is not all visible at once. Soft, flowing curves and bends create a natural look.

Start with the rocks and cobble. Rounded river cobble looks most natural for the creek bed. In nature, water flowing down a river would round off sharp rock edges to produce cobble of different sizes. A river never has just one size of rocks and yours shouldn?t either.

Accent rocks can be any type that you like as long as you get a variety of rock sizes and shapes. Use the larger stones to direct and channel water. Placing rocks on the outside of a curve creates a more natural look.

As in all gardens there is always a bit of maintenance to keep things looking and working great. Weeding in the first couple of months while plants become established is important. Replenish mulch as needed until the plants grow in.

Periodically remove leaves that have landed in your river bed and reposition rocks moved by runoff to keep your dry creek bed working for you when you need it. Also don?t start your dry creek bed too close to the foundation of your home if that area is flat. You can direct the water through a drain pipe connected to a downspout to a lower starting spot in your garden.

So whether you are adding a dry river bed to add interest to your lawn-free landscape or to double as catchment for winter storm runoff, make yours look like it?s always been there.

Screen the Neighbors with Low Water-Use Plants

We all enjoy privacy around our homes. Even if you?re best friends with your neighbor you don?t always want to wave at them each morning in your robe. Whether you have a property tucked way back in the forest with a next door neighbor that looks right down on your deck or a postage stamp size lot that could be an jewel if you just had a screen between you and the next property, there are techniques designers use to make your home a private oasis.

Narrow spaces can be challenging when you need to screen the house next door. There?s not room for a big, evergreen tree or hedge to solve the problem. One way is to use plants that can be espaliered against a fence or trellis. Some plants like azara microphylla naturally grow flat without much coaxing on your part. This small dainty tree is fast growing and reaches 15-25 ft tall. The yellow flower clusters will fill your garden with the scent of white chocolate in late winter. They are ideal between structures. I?ve used the variegated version to screen a shower and it?s working great.

Another small tree, the Compact Carolina cherry laurel can be espaliered also in a narrow space if needed. It grows 10 ft tall but that may be all you need to screen the neighbor. They are drought tolerant once established, deer resistant and the perfect host for birds, bees and butterflies. The leaves smell like cherries when crushed which gives this plant it?s common name.

A dwarf tree that also works nicely in this situation is a Southern magnolia called Little Gem. Naturally a very compact narrow tree it grows to 20-30 ft tall but only 10-15 ft wide. It can be trained as an espalier against a wall or fence and the sweetly scented flowers will fill your garden with fragrance.

Other small trees that make a good screen are purple hopseed, and leptospermum ?Dark Shadows?. Both have beautiful burgundy foliage. California natives that can be espaliered against a fence include Santa Cruz Island ironwood, Western redbud, mountain mahogany, toyon, pink flowering currant, Oregon grape and spicebush.

If you have a wider space to grow screening plants, one of my favorites is Pacific wax myrtle. This California native grows quickly to 30 ft tall with glossy, rich forest green leaves. Its dense branches make a nice visual and noise screen for just about anything or anybody. I?ve never used the subtle spicy leaves for flavoring sauces but I might try it next time a recipe calls for bay leaves. Best of all the fragrant waxy purplish brown fruits attract many kinds of birds.

Italian buckthorn is another evergreen screening shrub to consider. It reaches about 15 feet tall by 6-8 ft wide and has low water needs. It can grow 2-3 feet in its first few years making a quick screen. There?s a variegated version with stunning foliage that looks awesome mixed with the green variety in a hedge.

Another favorite hedge plant, the California coffeeberry grows 6-8 feet tall and gets by with very little summer water once established. Birds love the berries.

I also like osmanthus fragrans for a screen with a sweet scent and pittosporum ?Marjorie Channon? or ?Silver Sheen? with their showy variegated foliage.

If it?s just not practical to screen the perimeter of your property redirect your line of sight to keep attention focused on the garden instead of on the landscape beyond. A recirculating fountain as simple as an urn spilling onto cobbles at the base can disguise noise and become the focal point. There are lots of ways to add privacy to your home.
