Gardening for Frogs and other Creatures

Pacific tree_frog_on_potReading about the new wetland pond construction at the Ben Lomond SLV Homeschool in The Press Banner this past October 31st has me thinking about a low spot in my own garden that becomes soggy during the winter. Most mornings and evenings I hear the resident Pacific Tree frog singing his heart out. Maybe I can encourage even more frogs as well as dragonflies, salamanders and toads by installing my own wetland habitat. There are a lot of landscapes that I encounter that also have a ?problem? area with poor drainage and this would be the perfect solution. I?ve thought about building a wetland garden or bog garden for many years. This winter I?m going to do it.

The difference between a wetland garden and a bog garden is basically how long the water remains during the year. A wetland pond in our area is often seasonal, drying up in the summertime. A bog garden is damp even in the summer. A shady spot with a high water table is a good spot for a bog garden.

Wetlands are important to our ecosystem. One of the greatest wetlands in North America at Flame_Skimmer_dragonfiy-matingthe southern end of the San Joaquin Valley has almost completely vanished. There used to be almost 5 million acres of wetlands in the Central Valley and now only a small percentage remains. This habitat destruction is causing the disappearance of birds, frogs, amphibians and other wetland wildlife. You can help encourage these species in your own backyard and grow plants that are beautiful, too. Every little bit helps.

Most wetland plants don?t require standing water to grow successfully and will survive even in an area that appears dry most of the growing season. Many frogs including the Pacific Tree frog only need 3-4 weeks of water to lay eggs and the pollywogs to mature. Other frogs need a longer time to reproduce. The water need only be a little over a foot deep.

To create a wetland in an area that isn?t naturally moist and has heavy clay soil you will need to lay down a waterproof, nontoxic liner and cover it with soil. For a bog garden add decomposed plant matter and peat, Branches and logs can be placed around the edges as perches for birds and dragonflies and provide a spot for turtles to bask in the sun. Winter rains provide the best water to fill your wetland pond. Frogs and other amphibians are extremely sensitive to chemicals in tap water. Wildlife will be naturally drawn to your wetland. If you build it, they will come, I promise.

Blue_Damselfly-matingThere are many wetland plants that grow quickly when the soil in wet and then die back when the soil dries up only to return when moisture is again present. Species like cattails and rushes will do well being common in wetlands in our area. The plants you select depends on the amount of light, the length of time the soil will be saturated and the depth or water. Native trees like Big-Leaf maple, Red Alder and Box Elder are good companions for a wetland garden as are shrubs such as Snowberry, marsh baccharis and Yellow-twig dogwood.

Other native plants include Stream orchid, Deer fern, Horsetail, Cardinal lobelia, Twinberry honeysuckle, Cardinal Monkeyflower, Wood?s Rose, Blue Elderberry, Blue-eyed Grass, California Wild Grape and Giant Chain Fern.

Creating a mini-wetland in your own yard provides many of the same benefits that natural wetlands offer, providing habitat for creatures like butterflies, bees, salamanders, frogs and birds.

Gardens Change with Time

Leave a comment

quiet_path.1280Call it a trick, call it a treat, but all gardens change with time. It?s part of nature for the fittest to survive. Now possibly you have different ideas of what you want your garden to look like but it?s hard to fool Mother Nature. Recently I had the opportunity to visit a special garden in the Gilroy area that has evolved with time. This garden of California native plants truly demonstrates how nature can decide the best plants for birds, butterflies, wildlife and people.

It was one of our classic mild autumn days when several fellow landscape designer friends and I were treated to a tour by the enthusiastic owner of the 14 acres of land called Casa Dos Rios at the base of Mt Madonna. Jean Myers loves to share her deer_grass.1280property and especially the journey that has transformed it from a formal landscape with lots of lawn to the present truly native wild garden. She loves that the landscape now supports all sorts of wildlife including birds, mammals, reptiles, amphibians, insects and fish.

A few of the native plantings have been more successful than she would have liked, Jean laughed as she pointed out the California Rose thicket has taken over the entry garden. She wishes she had planted the native wood rose instead which doesn?t spread as much. She plans to remove the wild rose eventually to make room for other native plants that aren?t so aggressive.

At this time of year a native garden is at rest. There?s a quietness to the landscape as the wind blows through the grasses. Large swaths of deer grass have naturalized. Originally, Jean planted many varieties of native grasses and some still remain but the deer grass have been particularly successful. Jean explained that this grass was used for making baskets by the Ohlone Indians that used to live in the area. To keep this grass fresh looking she cuts them back to 6 inches from the ground in late winter.

Calif_fuchsia.1280The California Aster was still blooming along the path as we made our way to the frog pond. This plant is well liked by the native moths and butterflies, Jean said, as it provides a late source of nectar. The lavender flowers make perfect landing pads. The two species of butterfly weed bloomed earlier in the season and had already spread their seed for next year.

The frog pond consists of basalt columns that drip water into a deep pool filled with rocks which cools the water in the heat of the summer. Jean said the area is usually alive with birds but they were keeping their distance during our visit. Lots of time for them to bathe later when we weren?t invading their space. She said Pacific Tree frogs and Western toads call the area home, too.

Another late blooming plant, the California Fuchsia, covered a slope alongside massive granite boulders. You could barely see the foliage through the hundreds of flowers of this red blooming variety. These plants spread easily and with a bit of late winter pruning look great late into the season.

Jean loves all her native plants. From the butterfly garden to the bog garden she has a story to tell about each Calif_buckwheat.1280area. In the spring, Jean said, the native iris steal the show. She rounded up 600 of these from nurseries all over California when the garden was first planted. Grouping each type together she says was half the fun to keep the colors pure in each stand. I was amazed to see them in areas of full sun as well as part shade locations.

We picked late blackberries and raspberries as we walked around this amazing 14 acre property that benefits all wildlife. She is an avid birder and she and her husband manage two creeks, the Uvas and the Little Arthur that support hundreds more bird species, including bluebirds, swallows and owls. ?There?s so much for them to eat here.? says Myers. She lets nature feed and attract all the native wildlife that visits.

It was a privilege to listen to Jean share her enthusiasm for gardening with California natives to attract wildlife and to conserve water. I left with my pockets filled with seeds from native wild grape and clematis so I?ll always have a bit of Case Dos Rios in my own garden.

Traveling with the Mountain Gardener

Truckee_RiverSo far this year my travels have taken me up the coast of California and parts north. Then I headed a bit east to explore the Sierra Nevada. Statistics show that the drought is affecting all parts of the state. I?d heard that the Tahoe Queen had to modify it?s path around the rim of Lake Tahoe to avoid rocks. I had to check it out for myself. Just how low could that big blue body of water be? And what affect is the water situation having on the gardeners up there?

From the first glimpse of the Truckee river that is the sole outlet for Lake Tahoe I could see that the water was lower than usual. Still looked like enough water to negotiate a tube or small raft but the rafting companies have already closed for the season with the flow from the lake at only half of what it is normally in August. Hiking on the Tahoe Rim Trail next to the river was beautiful. The native plants and trees can exist even without the normal snowfall. They might not put on a lot of growth during dry years but they still looked healthy.

There is a chart at the dam where the Truckee river originates on the north side of Lake Tahoe. The graph shows that this is not the only drought event to have hit the Tahoe Basin. I was told the lake has been lower than this many times. Back in the 1930?s, 1962, 1976 and especially during the early 90?s the lake level dipped even lower. 2004 and 2010 were also low years. The lake level is just above the natural rim right now. The average daily evaporation rate of the lake is 397 million gallons.

In Tahoe City there is a destination nursery that I always visit when I?m in the area. In addition perennial_borderto several acres of trees and plants, the Tahoe Tree Company?s grounds are beautifully landscaped. A small lawn in surrounded by perennial beds loaded with flowers and a gazebo bordered with Autumn Joy sedum was just starting to bloom. Stands of quaking aspen towered over the shade beds of hosta, begonia, astilbe and New Guinea impatiens.

I asked one of the employees about how the drought has affected their customers. I noticed that many of the local residents had bright green lawns surrounded by dahlias, rudbeckia and ornamental grasses. She told me that many water companies serve the communities around the lake. They get some water from the lake itself but the rest is from springs which are drying up. The Tahoe City Public Utility District recommendation is to reduce water consumption by 20% with watering on even or odd days depending on your address.

Changes this season at the nursery range from reduced sale of seeds because seeds need regular watering to get started. Also customers are requesting more native plants but I was told that some of those requested are high water usage plants like dogwoods and willows. Customers are mulching more and learning which plants are drought tolerant. Popular natives include Sierra currant, Bitter and West Sand cherry, Mountain spiraea and elderberry.

Sun_King_AraliaStrolling the grounds of the nursery a brilliant gold plant caught my eye. Morning sun shone on a group of Sun King aralia and I had to find out more about this beautiful plant. In mid-spring this fast growing, 6 foot plant emerges with bright gold leaves. In sun the foliage remains gold through out the summer. In full shade, the foliage will be chartreuse to lime green in color. Spikes of tiny white flowers emerge in summer followed by ornamental black fruit. This plant is deer resistant. It?s needs some moisture so combine it with other average water users in the same bed.

We are all hoping this winter will bring us some relief from the drought, even those who live next to that big blue lake.

Organic Gardening in the Pacific Northwest- Part 2

deer_Japanese_mapleLast Christmas I gave my sister a Beni Kawa Japanese maple. This tree sports even brighter red bark in the winter than the more familiar Coral Bark maple. She recently sent me a picture of a deer standing right next to it and looking? longingly at it?s next meal. Her tree wasn?t nibbled that day but I was anxious to visit Fox Island where she lives in the Pacific Northwest to check on it for my self.

The morning after I arrived I heard the neighbors next door outside in their garden chatting. I have seen their vegetable garden from outside the fence as I drove by and was curious what they had growing in there. I introduced myself and was offered fresh picked blueberries, raspberries and strawberries. ?Come by after breakfast and we?ll give you a tour?, they said. I could hardly wait.

The front of Bob and Bev?s corner lot is landscaped with perennials, flowering trees and shrubs. Everything on the property is grown organically, they told me. ?The weeds can really get out of hand up here with all the rain?, they hydrangea_paniculata_Limelightlamented. The back garden containing the edibles is fenced but the front is open to the local deer population. A massive Limelight hydrangea paniculata dominates the entry. Covered with hundreds of lime green blooms that will turn pink in the fall, Bob told me he sprays it weekly with Liquid Fence deer repellent.

White coneflower, dahlia, crocosmia, hosta and gladiola are just a few of the perennials in their landscape. Bob and Bev mix native plants with other plants they like. Native Oregon grape front_perennial_bedground cover and manzanita cover the sloping bank along with a small stand of vinca minor that is well behaved. Bev does wish she hadn?t planted the bugloss under the flowering plum but say?s the little blue forget-me-not flowers each spring are worth the effort it takes to keep it in check.

In the back, protected by a perimeter deer fence is where the edibles live.

On one side of the yard is a 40 foot stream Bob designed and built himself. Along the curving bank they have planted Oregon grape, salal, kninnikinnick manzanita and snowberry. Woolly thyme and black pussy willow also grow alongside. Wild birds love bathing in the stream. Bob used the leftover soil and rock from the stream project to construct a streammound for overbearing strawberries.

Another bed of strawberries is still producing. This one is built from timbers and amended soil from compost Bob and Bev make themselves.

The raspberry crop was great this year, Bev said. I had tasted a few and she wasn?t exaggerating.

They have an attached greenhouse, that Bob designed and built. ?Overbuilt?, they both laughed.? Bob?s an engineer and couldn?t help but design thermal windows, fans, vents and a heating system that allows them to grow back-up tomatoes in the summer and to start seeds in the winter. The double pane windows keeps the temperature inside in the 40?s without the heat having to kick on. A meyer lemon grew lush in the corner covered with blossoms and fruit.

cornBob was advised he could never grow corn in the Pacific Northwest but being from the midwest where corn is king he had to try. Their crop was just setting ears at 4 feet and will grow to 7 feet tall by the end of summer. ?They?re delicious?, he told me.

All bare soil in this organic garden is covered with bark chips. Bev told me she listens for a chipper in the neighborhood and tells them where to drop it off. They swear by this type of mulch. ?Like gold?, Bev laughs.

Bob and Bev make gardening in the Pacific Northwest look easy. Their garden is the result of many hours of pleasant work and it shows.

Add Drama to the Garden with Large-Leafed Plants

Leave a comment

philodendron_selloumGardens have different personalities. Some gardens mimic nature with plants that attract birds and butterflies and other wildlife and look a bit wild. Some are neat and tidy with perennials lined up evenly along pathways and clipped hedges under the windows. All gardens are a reflection of their owners.? When I visit a garden to help the owner change, add or ?take the garden to the next level? I know which ideas will resonate with that person and which will just not work for them. Sometimes it?s easier for someone looking at a garden for the first time to visualize what?s needed.

Regardless of your style I often recommend one simple solution to update a garden. Many gardens end up with too many small-leafed plants. Nature is the master at this survival strategy. Small leaves are often more efficient at retaining water in drought conditions. When all your leaves are the same size, however, the garden gets boring. Using large, bold architectural plants allows the eye to rest on a focal point rather than try to take in everything at once, scanning back and forth.

Plants, like people, come in all sizes and shapes and so do their leaves. Some have huge and dramatic leaves while others are just showy and outsized enough to work well when viewed up close or at ground level. Some plants look tropical and others are right at home in the redwood understory. Some require regular water while others are able to withstand some drought. There?s a bold, breathtaking plant for every garden.

Because they reflect light, glossy leaves look even larger than they are. Make those leaves variegated or wavy with a dimpled texture and the effect is even more striking.

Here are a few large-leafed plants that work well in our area.

In partial shade try Fatsia japonica also called Japanese aralia. It?s deer resistant with bold foliage thatfastia-japonica looks tropical but still at home in the forest. Philodendron selloum with its huge, glossy leaves is also easy to grow. Oakleaf hydrangeas have it all: bold foliage that turns red in fall as well as huge white flower clusters in summer.

Tasmanian tree ferns are hardier in our winters than the Australian variety and are about as dramatic a plant as you will find. Bear?s Breech require only moderate water and serve well as a focal point in the garden.

hosta_Sum_and_SubstanceIn my own garden, I?m finding the chartreuse leaves of Hosta ?Sum and Substance? can take more sun than I originally thought. The deer walk right by their thick, dimpled leaves which is a definite plus. I like all hostas for their bold leaves whether variegated, glossy or wavy.

At ground level, some of my favorite large-leafed perennials that require only moderate water include hellebore, aspidistra, bergenia, coral bells and the dry-shade California native. wild ginger or asarum caudatum.

If you garden in more sun you can add pizzaz to your garden by planting something with large-leaves inasarum_caudatum front of those tall ceanothus, manzanita and toyon. Matilija poppy is a show stopper if you have room for it. Rhubarb, windmill palm, smoke bush and Western redbud also have huge leaves as do canna lily, banana, sago palm, loquat and angel?s trumpet. These are just a few of the many plants with big leaves that work magic in gardens around here.

Adding plants with dramatic foliage instantly makes-over the garden.

Dogwood in the Santa Cruz Mountains

Leave a comment

dogwood_RoblesEarlier this year the flowering plums were the first trees to welcome the beginning of spring. Then came the flowering cherries, crabapples, pears, redbuds and lilacs. But now the flowering dogwoods take over as the stars of the show. They are blooming everywhere I go. Whole neighborhoods, lined with dogwood trees, are coming to life.? I? know of several beautiful specimens along Hwy 9 that bursts into bloom this time of year covered in snowy white, pink or rosy blossoms. There are many types of dogwoods and every garden has the perfect spot for at least one. What better way to honor Earth Day 2014 than to plant a tree?

When thinking about where to plant your dogwood tree consider what role you want cornus_florida_closeupthe tree to play in your garden. You might place it where it becomes the main focal point especially during the spring flowering season but also where you can enjoy the brilliant fall foliage. Maybe one located at the back of the garden would be nice drawing the eye along a path and the flowering shrubs growing along the edges.

Dogwoods need good drainage. If your garden has heavy clay soil plant your tree in a raised bed. They make excellent understory trees in high filtered shade if the air circulation and drainage are good. With 2-3″ of mulch dogwoods thrive in full sun, too. The fungal disease anthracnose is not usually a problem here in our summer dry area if drainage is good. Hybridizers have successfully crossed the Japanese dogwood, cornus kousa, with the eastern dogwood, cornus florida, to create the wonderful disease resistant Stellar series. Also the native Pacific dogwood, cornus nutalli, has been crossed with the eastern variety to produce Eddie’s White Wonder. Both are good choices.

cornus_florida_closeup2The beautiful flowers of the dogwood are actually bracts, a leaf-like structure surrounding a flower. The colorful bracts of poinsettias, the magenta bracts of bougainvilleas and the bracts of the dogwood are often mistaken for flower petals. No matter what you call them, the blossoms are spectacular.

Dogwoods attract a variety of wildlife. All sorts of critters use this tree for food and shelter. The giant silk moth and several species of butterflies favor dogwoods as host plants. The spring flowers provide nectar to bees and other pollinating insects. Robins and sparrow are just two of the bird species than build nests on the horizontal branches and many others seek shelter in the leaves. The high calcium, high fat, fleshy red fruits are eaten by 35 species of birds including titmice, juncos and waxwings.

The fruit of flowering dogwood is poisonous to humans but the root bark was used by Native Americans as a fever reducer, skin astringent, an anti diarrhea agent and as a pain reliever for headache and backache relief. It was also use to counteract the effects of many poisons and as a general tonic. The flowers were infused to reduce fever and relieve colic and several plant parts were used as medicine for blood diseases like malaria.

Because dogwood leaf litter decomposes more rapidly than most other species it has been planted on abandoned strip mines and used for urban forestry projects. The wood is hard, strong and shock resistant, making it suitable for wood products that need to withstand rough use like tool handles, roller skate wheels, golf club heads and knitting needles and spools.

Dogwoods look so great in our area because we get some winter chill.? Some of cornus_capitata_closeupmy favorite varieties include cornus capitata also known as Evergreen or Himalayan Dogwood. It’s a slow growing tree which will reach 20 ft tall after about 25 years and has large white blossoms.

Other common favorites with rosy flowers are Eastern dogwood, Cherokee Chief and Cherokee Brave. Their leaves turn glowing red in fall with fruit lasting well into winter. There are lots of white blooming varieties also and this tree is the parent of the exceptional hybrid Eddie’s White Wonder and the anthacnose-resistant Stellar Pink.

The Japanese dogwood, cornus kousa, starts blooming several weeks later than the Eastern varieties and continues for 5-6 wks. The flowers open along with the leaves which is different than its relatives. This dense multi-stemmed tree grows to 20 ft tall.? With raspberry-like fruits that persist into winter and leaves that turn yellow or scarlet in autumn it’s a beautiful addition to the garden.

Remember a mature leafy tree produces as much oxygen in a season as 10 people inhale in a year. Trees clean the soil and air of pollutants, act as windbreaks and can muffle noises.
