Watering Tips when Planting for the Birds & Bees

Western Tiger Swallowtail butterfly

I may not be so fond of gophers but I never tire of the birds, butterflies and bees that visit my garden. I?m always on the look out for plants that will attract even more of these exquisite creatures and it?s one of the top requests for nearly every garden that I design. Fortunately there are many plants that fit the bill and have low water requirements for our summer dry climate.

Trees that provide fruit, seeds, nectar and protein from insects attract many kinds of songbirds. Our native Big Leaf Maple is a favorite of the Evening Grosbeak who relish the seeds and early spring buds. Another bird magnet is the dogwood. Our Pacific dogwood as well as the Eastern dogwood and even the hybrid of the two, Eddie?s White Wonder, all are very valuable sources of food for many birds. Their summer berries are high in fat and important for migratory and wintering birds.

Lesser goldfinch

There are many great low water-use shrubs and perennials that attract birds. My favorite Lesser Goldfinch is partial to the seeds of yarrow, buckwheat and aster. Kevin?s mahonia is favored by Western bluebirds. Blooming now in our own neck of the woods is Mexican elderberry. Their butter yellow flowers will form purple berries rich in carbohydrates and protein and attract an incredible number of birds. And I always can find space for another variety of manzanita or ceanothus.

Mimulus ‘Jelly Bean Gold’

Both hummingbirds and butterflies are attracted to flowers that provide nectar. Among their favorites that won?t break your water budget are natives such as penstemon and salvia. galvezia, mimulus, monardella. California fuchsia and ribes are also important nectar sources for birds in your garden. Add a couple non-native, drought tolerant perennials like lavender, gaura, coreopsis, verbena, scabiosa, lantana and wallflower and you?ll provide a feast for all your winged visitors.

So how much water do different types of plants need during the heat of summer?

As a rule of thumb, trees and large shrubs need deep but infrequent waterings. They should be on a separate valve than your smaller shrubs and perennials. Water ornamental trees 1-3 times per month depending on the type and soil. Tree roots grow 12-36? deep and require 10 gallons of water per inch of trunk diameter.

Sambucus nigra berries

Apply with a soaker hose, drip system emitters or hand held hose with shut off and soft spray attachment according to your water districts restrictions. Don?t dig holes in the ground in an effort to water deeply. This dries out roots even more. Be sure to water the root zone to the indicated root depth every time you water. Watering deeper than the root zone only means you are wasting water. You can test how deep you watered by pushing a smooth rod -1/4? – 3/8? in diameter- into the ground soon after you irrigate. The soil probe should easily slide through the wet soil but become difficult to push when reaching dry soil.

The roots of smaller shrubs are 12-24? deep in the soil. Established native shrubs may need only monthly irrigation to keep them looking their best while other shrubs may need watering every 7-10 days during the heat of the summer. Perennial roots only go down 12? or so and may need watering once or twice a week depending on type.

With lots of mulch and the above watering tips you can keep all your plants happy and healthy for the birds, butterflies and bees to enjoy.

Climate Smart Plants for the Garden

verbena_lilacina-blue_oat_grass

All this talk about ?drought tolerant? plants or ?water smart? plants is misleading in some ways. What really matters for the success of a plant in your garden is that they are climate smart. You can call the new California garden climate tolerant or climate adapted but it all comes down to the same thing. The plants you choose to grow in your garden should be able to naturally tolerate periods of lower than average water. This doesn?t mean no water during extremely long dry periods. No plant can live without water.

I have two books that I look to for plant ideas when called upon to design a garden in our area. This first was published by East Bay MUD in 2004 and is called ?Plants and Landscapes for Summer-Dry Climates?. The other book I refer to regularly for ideas and information is ?California Native Plants for the Garden?. Both are invaluable in these times of water conservation. One of the best tips each of them offer is to garden where you live.

All of us live in a summer-dry climate. Summer-dry gardens are naturally dry for long periods. Knowing which type of plant community you live in can make the difference between success and failure in your garden. Choose the right plant for the right place whether it?s a California native from an area with similar soil and exposure or a plant from another Mediterranean-like climate with growing conditions like yours.

Plant communities have evolved over time with geologic changes in climate, topography and soils. We have several district areas here- mixed evergreen forest, redwood forest, chaparral and sandhills.

If you live in a mixed evergreen forest you garden with trees like coast live oak, tan oak, madrone, bay and buckeye. Understory plants include ceanothus, coffeeberry, hazel and poison oak. Your soil contains serpentine and granite. Many other unthirsty plants like salvias, lavender, santolina, society garlic, giant feather grass, rosemary and rockrose do well here. California natives such as western mock orange (philadelphus lewisii), wild ginger and western sword ferns grow here also.

Mixed evergreen forest may also be found along canyon bottoms near streams where big leaf maple, white alder, cottonwood, and western sycamore trees grow. Most plant here grow lush in this deep soil. If you are looking to add something new to your garden here consider giant chain fern, aquilegia, dicentra, Pacific Coast iris and fuchsia-flowering gooseberry.

Chaparral areas are the hottest, driest slopes of these mountains. Dense thickets of manzanita, coyote brush, chamise, coffeeberry, ceanothus, monkey flower and sage are native here. These plants are adapted to little water and often have tiny, thick, waxy, light green or grayish leaves. Soils tend to be rocky and shallow with overlaying rock or a subsoil that is mostly clay. Plants here need to have an extensive root system that reaches widely and deeply for water. If you live here a classic combination would be the spring blooming western redbud and Julia Phelps or Dark Star ceanothus. The combination of magenta and electric blue flowers is unforgettable.

The sandhills near Quail Hollow and Bonny Doon around Martin Rd. are part of an ancient sandy sea floor that was uplifted, eroded and exposed. These sandy soils lack organic matter and nutrients and their white color magnifies the temperature of the summer sun. Unique, native plants like silverleaf manzanita and Ben Lomond wallflower live here. Buckwheat and sticky monkey flower do well here. You might also try growing Lewisia, a pretty little plant native to northern California, thrives in sand and gravel soils with good drainage. This 8″ tall hardy perennial blooms from spring to early summer with extremely showy flower clusters in colors ranging from apricot to pink, rose and bright cherry red. Mulch them with gravel or crushed stone.

Remember right plant-right place. Don?t try to force nature although most gardens do look better with some summer water. Closer to the house we expect a fuller look. Combinations I?m going to try this season include leucospermum paired with blue echium or grey-leafed westringia planted with red-flowering callistemon ?Little John?.

Adding Bright Color to the Garden

Yellow primrose

Do you ever look at the collection of cut roses at the market and think ?Which is my favorite color today?? Sometimes it?s the strawberry pink ones I?m drawn to other times i like butterscotch or deep red. It?s the same dilemma in my garden. I try to use restraint and stick to just 3 colors but who can do that, really? In early spring I love the soft pink and pure white of bleeding hearts, camellias and early rhododendrons but maybe because I?m surrounded by so much green, I?m drawn in summer to the bright jewel colors of orange, yellow and red in my garden.

Clivia miniata or Kaffir lily

I?m looking forward now to my orange clivia flower clusters that are emerging from deep within the dark green strappy leaves and will be opening soon. The color is especially vivid on a dark rainy day. I also have lots of deep golden and red primroses blooming now. I?ve enjoyed these same plants blooming repeatedly for many years in partial shade. I even get some sporadic blooms throughout the summer.

hakonechloa_macra_Aureola
Japanese Forest Grass – hakonechloa macra ‘Aureola’

Also at this time of year I get color from foliage too. My ?All Gold? Japanese forest grass and the variegated one have emerged from winter dormancy and they are some of my favorites. Besides being deer resistant the sound of the leaves rustling in the wind adds another dimension to the garden. The chartreuse leaves of heuchera ?Citronelle? – coral bells – add a colorful touch of foliage all year round. There?s a variety called ?Lemon Chiffon? and another named ?Lime Rickey? that i want to add to my collection also.

Later in the season I look to brighter flowers to brighten my garden. High on my wish list for several years is the kniphofia or red hot poker. In addition to yellow and red varieties there?s a cool dwarf one called ?Mango Popsicle? available now. This terrific drought tolerant plant attracts hummingbirds and blooms continuously from late spring into fall. Other colors in this dwarf ?Popsicle? series are banana, creamsicle, lemon, papaya, pineapple and fire glow. All would look awesome planted in a drift.

There are so many plants I want to add to my perennial garden on the terraces between the low rock walls. Some of the existing plants are California natives like salvia ?Bee?s Bliss? with some water smart South African plants such as coleonema ?Sunset Gold? and leucodendron ?Safari Sunset? and an Australian grevillea ?Coastal Gem? thrown in.

Because I wechinacea_Hot_Coralant to add more vibrant colors to this area I?m looking to some of the new?echinacea or coneflower. From deep gold to pumpkin orange to red-orange sunset colors this perennial has medium water needs once established and is deer tolerant. I?m hoping the seed heads will attract more goldfinches to my garden if I don?t deadhead but allow the flowers to remain on the stalks throughout the summer and into the fall. I can also plant more California native grasses for the goldfinches like blue and yellow-eyed grass and festuca californica.

Santolina 'Lemon Fizz'
Santolina ‘Lemon Fizz’

A plant like santolina ?Lemon Fizz? provides chartreuse mounds of fragrant foliage for year-round color. In the summertime it?s topped with bright yellow flowers. This compact evergreen plant is perfect to edging pathways, borders and in herb gardens. Plant in mass for a colorful, drought tolerant ground cover.

I have quite a few native sticky monkey flowers in orange and yellow that the

hummingbirds love. Also the reddish-orange California fuchsia adds color to my landscape later in the summer cascading over the rock wall. A lemon yellow fremontodendron or flannel bush would add some height to my slope.

Also I?ve wanted an Island Snapdragon or galvezia speciosa to add to my red-yellow-orange color scheme. This evergreen California native blooms with bright red snapdragon-like flowers in late winter through early fall. It?s a tough plant and very adaptable to many garden situations and soils. It can

even be hedged or pruned to ground level to keep the foliage fresh.

The bright colors of yellow, orange and red play well with blues and purples and are especially useful in mid-summer when the harsher light of the direct overhead sun can wash out paler hues.
