Attracting Birds to your Garden

Fall brings with it not only foliage color but also colorful fruits and berries that invite birds into your garden. If you’re a backyard birder you probably already have lots of plants to lure our feathered friends,

If you have room for a new tree, consider Paul’s scarlet hawthorn.  With clusters of double rose flowers and small vivid red fruits resembling tiny apples in late summer and fall that hang from the branches well into winter, this tree offers interest in more than one season.  Robins are attracted to hawthorn berries.
 
Flowering crabapples sport showy edible fruit relished by many birds in the winter, including black-headed grosbeaks.  Fruit color ranges from reddish purple, brilliant red to golden orange.  Crabapples are good lawn trees and their spring blossoms are stunning.  To avoid disfiguring diseases, choose varieties that are resistant to cedar-apple rust, scab and powdery mildew.   Among these is ‘Prairiefire‘, with pink flowers and dark red fruit.  This tree grows 20 feet tall.
 
A native that puts on a fall show is  A background plant most of the year, the white berries on this 4-foot shrub stand out when the leaves drop.  Snowberry is a good choice for erosion control on banks.

Looking like clusters of pale purple pearls, the gorgeous fruits of beautyberry ( Callicarpa ) are born well into winter.  This deciduous shrub reaches to 6 feet and takes sun or light shade.
 
For both bird-attracting berries and brilliant winter stems, plant redtwig dogwood.  Native along creeks and other moist spots from northern California through the Northwest, it performs well with little additional summer water once established in gardens
 
Other shrubs with beautiful colored berries include barberry, cotoneaster, currant, elderberry, mahonia, nandina and pyracantha.  As an added bonus many of these berries make good holiday decorations, too. 

 

Groundcover Tips for Fall

The autumnal equinox happened this week. It’s the official start of fall when the sun crosses the celestial equator and moves southward. The earth’s axis of rotation is perpendicular to the line connecting the centers of the earth and the sun on this day. Many people believe that the earth experiences 12 hours each of day and night on the equinox. However, this is not exactly the case.

During the equinox, the length is nearly equal but not entirely because the day is slightly longer in places that are further away from the equator ( like where we live ). Also the sun takes longer to rise and set in these locations as it does not set straight down but in a horizontal direction.

Take advantage of fall planting weather by looking at what’s covering your ground. Be it the small lawn for the kids to play on, ground cover to keep the weeds at bay or erosion control to keep the hillside intact, this is an excellent time to plan for winter.

Let’s start with the lawn. If you still need a space for recreation, this is a good time to reseed those bare spots. Also to keep the lawn healthy, remove underlying thatch with a thatching rake. Then aerate the lawn by poking holes in the sod and fertilize with a complete lawn fertilizer like an organic all-purpose. Your lawn needs the phosphorus in the fall to encourage deep, strong roots for the winter.

If the kids are grown and no one is using that lawn, why not rip out the water guzzling grass and replace it with a walk-on groundcover? There are many to choose from like dymondia, lippia, potentilla duchesnea strawberry and several kinds of thyme.

One of my favorites is Elfin thyme. It doesn’t need mowing, edging or fertilizing or much irrigation. You can walk on it and it stays green all winter, shading into bronze tones when the weather cools. It even blooms in midsummer for several weeks. Bees will be attracted to it at this time. Thyme prefers sun and poor, sandy soil. Autumn is the best time to install from flats cut into 4" plugs planted about a foot apart. It will fill in within 3 years. Plant them closer together if you’re impatient. You’ll love your new lavender-blooming "lawn".

There are also Ca. native and prairie meadow grasses that you can walk on. They need little irrigation and even less mowing. Some can be planted from seed, others from plugs or sod. Good choices include Idaho, Calif. and red fescue, carex pansa, June grass and Hall’s bentgrass.

If you don’t need to walk on your groundcover, low-growing shrubs that are good groundcovers are baccharis, ceanothus maritimus, cistus salviifolius, grevillea lanigera, creeping mahonia, rosemany prostratus, rubus, manzanita, creeping snowberry and ribes viburnifolium to name just a few.

It’s time to enjoy fall weather and cover that ground before winter.

Why Plant in the Fall?

Those lazy, crazy, foggy days of summer are behind us now. What a strange summer it was. Checking my un-scientific weather records I’ve kept since 1999, I find no other summer that was as cool at this one. This comes as no surprise to you tomato growers out there, I know.   At the other end of the spectrum, a few years, like the summer of 2006 and 2008 were real scorchers. We’re all looking forward to Indian summer which is the best planting season of the year.

There is plenty of time to plant California natives, Mediterranean plants or any other perennial, shrub, grass or tree.  By r, roots have a chance to grow all autumn and most of the winter as well without having to supply nourishment to the leafy portion of the plant. Roots of deciduous plants still grow even after plants drop their foliage as long as the ground temperature is above 50 degrees.  Cooler day and night temperatures slowly harden off the top of the plant to prepare for the cold days of winter.

Another reason that fall is the no-fail planting season is because plants put in the ground in fall need less water to establish. Plants themselves use less water since photosynthesis is slowed by shorter days even if it’s occasionally hot. Evaporation rates slow down also during fall so water in the soil lasts longer as well. Sometimes we get lucky with fall and winter rains perfectly spaced so the ground never completely dries out.

Even cool season annuals such as snapdragons, pansies and violas, Iceland poppies and primrose planted in early fall have time to develop better roots before flowering and because they start blooming earlier they bloom over a longer time.

So get out the shovel, prepare you soil and make a shopping list.

Plants that thrive in dry, shady spots benefit especially from fall planting as they need established root systems before next years dry season. Dry shade sometimes occurs in places beyond the reach of the hose but also under native oaks. To protect their health, it’s a requirement that plants underneath thrive with little or no summer irrigation.

Plants of proven success under these conditions include native currants and gooseberry. Claremont pink flowering currant ( Ribes sanguineum var. glutinosum) are beautiful in spring with pale pink flower clusters that darken as they age. The powdered, blue-black berries are edible although the seeds are bitter. To get a taste of the fruit, though, you’ll have to compete with the birds. Chapparal currant is another tough reliable shrub that blooms early and often, flowering from December through March. The pendulous flower clusters are 2-6 inches long and range in color from dusty pink to rose red.

Other winning shrubs for dry shade include mahonia, nandina, osmanthus, snowberry, coffeeberry, aucuba, barberry and upright manzanita.

Groundcovers that thrive under oaks or other dry shady spots include hellebore, evergreen currant, correa, manzanita and sarcoccoca.

Whatever conditions you have in your garden, don’t miss out adding some great plants during the fabulous fall planting season.
