What to do in the Garden in September

I never want summer to end. Who doesn't love those long days and warm nights? The calendar might say fall is near but Indian summer is one of the our best seasons so I love this time of year, too. But then I get all excited when spring rolls around and everything is in bloom. It's all good. I have a check list of some garden tasks  I need to do at this time of year so I better get to them between hiking and trips to the beach.

Fertilize shrubs lightly one last time if you haven't already done so last month. All shrubs, especially broad-leaved evergrimperata_cylindrica_rubrum2eens such as rhododendron, pieris, camellia, hebe, need to calm down, stop growing and harden off to get ready for the winter cold. Some plants have already set next year's buds.

Roses especially appreciate a bit of fertilizer now, encouraging them to bloom another round in October. To keep them blooming make a habit of pinching and pruning off old flowers. Always cut back to an outward facing branchlet with five leaves. There are hormones there that will cause a new rose to grow much sooner than if you cut to one with only three leaves. You can always cut lower on the stem if you need to control height.

Deadhead flowering annuals and perennials in the ground as often as you possibly can. Annuals like zinnias and cosmos will stop blooming if you allow them to go to seed. The same is true of repeat blooming perennials like dahlia, scabiosa, echinacea and lantana. Santa Barbara daisies will bloom late into winter if cut back now.

These plants know they're on this earth to reproduce. If they get a chance to set seed the show's over, they've raised their family. Try to remove fading flowers regularly and you'll be amply rewarded. If you want to start libertiaperennial flowers from seeds this is the time so that they'll  be mature enough to bloom next year.

Now through October, divide summer blooming perennials like agapanthus, coreopsis, daylilies and penstemons that are overgrown and not flowering well.  You can also divide spring blooming perennials like candytuft, columbine, astilbe, bergenia and bleeding heart but sometimes they don't bloom the first spring afterwards due to the energy they use re-establishing themselves.  If you're on  a roll out in the garden, though, go for it now.

It's still a little hot to plant cool season veggies starts in the ground. They appreciate conditions later in September when the soil is still warm but temps have cooled. It is OK to plant seeds of beets, carrots, spinach, arugula, mustard, leeks, onions, peas, radishes and turnips.

If you aren't going to grow vegetables in the garden this fall consider planting a cover crop like crimson clover after you've harvested your summer vegetables.  Next month I'll talk about how to go about doing this and how this benefits your soil.

Cut back berries vines that have produced fruit.  Canes of the current season should be trained in their place.

OLYMPUS DIGITAL CAMERASpider mites are especially prolific during hot, dry weather.  Sometimes you don't even know how bad the infestation is until all your leaves are pale with stippling.  Periodically rinse dust and dirt off leaves with water.  Spray the undersides of infected leaves with organics like insecticidal soap switching to neem oil if they build up a resistance to one of the pesticides. 

Now that you've taken care of your chores reward yourself by  to your garden for color in late summer through fall. Take a look at the garden areas that aren't working for you and replant. Good choices include aster, chrysanthemum, coreopsis, and gaillardia. Abutilon also called Flowering Maple come in so many colors that you probably need another one in your garden.  Petite Pink gaura looks fabulous planted near the burgundy foliage of a loropetalum. Don't overlook the color of other foliage plants like Orange Libertia and Japanese bloodgrass in the garden.

One last to do:  Make a journal entry celebrating the best things about your garden this year. 
 

Lessons from the Sierra Nevada

Lake Mary2Maybe we can't improve on Mother Nature but can we learn from her to make our own gardens more beautiful. My late summer travels this year took me to Lake Mary in the Mammoth Lakes area where I began to get ideas. This small Sierra lake formed in a depression in the glacial moraine below majestic Crystal Crag. Dozens of small streams keep the meadows blooming with wildflowers even in August. Granite slabs and obsidian domes the size of small states create an impressive landscape. Everywhere I looked I  saw how the plants, stone and water came together to make a combination that would look incredible in a regular garden.

Horseshoe Lake nearby was particularly fascinating for another reason. Back in 1990 the pines near the lake began to die off. Drought and insect infestation were first suspected but were found not to be the cause. It wasn't until 1994 that a soil survey revealed an exceptionally high concentration of carbon dioxide. The trees were being killed by CO2 in their root zone.

What caused such high concentrations of this gas? A swarm of earthquakes in 1989 allowed magma to push up from deep within the earth into tiny cracks causing limestone-rich rocks beneath Mammoth Mountain to be heated and release carbon dioxide gas. We also live in earthquake country. Thankfully this has never happened around here.

The art of bonsai involves creating nature in miniature. The Eastern Sierra does it on an immense scale. The boulders are huge beside the trail, the conifers towering above you as you hike. You can take this same look and scale it down to garden-size.

Evergreen conifers are often overlooked as additions to the landscape. If a white fir or bristlecone pine won't fit into your backyard there are many smaller types that provide year round structure. Maybe a 4 foot golden Feelin' Sunny deodar cedar would look spectacular in a small border, rock garden or container. Or how about a dwarf Wilma Goldcrest Monterey cypress against a backdrop of trees or shrubs with red or purple foliage? Don't overlook these elegant workhorses in the garden.

Pink Sierra Currants, adorned with shiny, translucent fruits were ripe for the picking as I walked along the trail on the way to Box Lake in the Rock Creek area. This currant is similar to our familiar red-flowering currant but is a smaller bush. I found it growing in moist areas as well as dry spots and would do well in any garden.

Blue Sierra lupine, Crimson columbine, blue Sierra Fringed gentian, pyrola or pink wintergreen and spice bush or calycanthus occidentals are just a few of the wildflowers still blooming in profusion. Given similar conditions all these beautiful flowers will grow in your garden. Tucked next to an accent rock you can have the Sierras right out your own window.

The diversity of plants on the eastern side of the Sierra is made possible by three vegetative communities: the Sierra Nevada range, the Great Basin and the North Mojave Desert. Our own area is rich also in plant species. Our cool moist coastal conditions and warm dry chaparral allow us to grow an amazing number of different kinds of plants. Enjoy all that your garden can be.
 

Native Plants for Winter Birds in the Santa Cruz Mts.

There's no way around it. January may signal the start of the new year but most of our plants still have the day off. I need inspiration on these cold mornings when most of my plants are asleep. This is the time of year when it's doubly important to include plants in your garden that can take a licking, keep on ticking and provide some much needed food for our feathered friends.

During the winter small songbirds and hummingbirds face big challenges, too. Just like us, they need to keep warm.  Our fuel might be a comfort food like hot stew, theirs are foods rich in antioxidants and fats or high octane nectar. Native shrubs with berries or nectar at this time of year will benefit them as well as providing hardy winter color in your garden.

Small flocks of Chestnut-backed chickadees frequent my garden regularly. I can hear their familiar chattering from quite a distance. I read in Audubon magazine that they weigh about as much as a dozen paperclips but their bodies are large for their mass. They have to ramp up the number of hours they devote to feeding. At night chickadees cram themselves into tiny cavities and shiver, burning the day's fuel to keep from freezing.

Other birds that I enjoy in my garden at this time of year are Lesser goldfinches, Townsend warblers, Ruby-Crowned kinglets, robins, brown creepers, Hutton's vireo, Dark-eyed juncos and Anna's hummingbirds.  These native plants will make both of you happy and it's not too late to plant.

Mahonia (Berberis aquifolium) is one of my favorites for winter color and spring berries. Fat cluster of golden yellow flowers light up the Douglas fir woodland understory. In the garden it has a surprising level of adaptability to tough conditions including low water, not-so-great soil and shade or partial sun. In the barberry family, they have gorgeous prickly foliage and powdery-blue, then black berries that the birds devour in late winter and early spring. Hummingbirds rely on the flowers as a source of nectar-rich food in wintertime when there isn't much else around. I saw them visiting these beautiful flower spikes in Seattle recently at Chihuly Glass Exhibit (got the spelling right this time). There are many cultivars of mahonia now available and they are all great.

Common Snowberry (Symphoricarpus albus) is a native that starts its show in fall. It thrives in a woodland garden or in the dry shade under oak trees. A background plant most of the year, the white berries on thie 4-foot shrub stand out when the leaves drop.  Seldom troubled by pests this small shrub can be used to control erosion and is deer resistant. Beautiful ornamental white fruits cover the plant at this time of year and are valued by varied thrush, robins and quail.

Hairy honeysuckle (Lonicera hispidula) can  provide both berries and nectar for local birds. Large, pink nectar-rich blossoms give way to red juicy berries in the fall and often hang on the vines during the winter. They are relished by birds. By pruning them a bit to get more branching they'll be denser and flower more. It's as deer proof as they come. They do well in clay soil in full sun and also shade. Snowberry, Hummingbird sage, toyon and coffeeberry are other natives that complement them.

Toyon (Heteromeles arbutifolia) is the official shrub of the State of California. Also called the Christmas berry shrub it's common in chaparral and open wooded forest. Many birds enjoy their bright red berries throughout the winter including cedar waxwing, bushtit, warblers, robins, flickers, finches and sparrows.  Toyon make a good screen as well as a beautiful specimen plant. They are drought tolerant when established but tolerate some water in the garden if drainage is good. They are relatively fire resistant, like full sun but will tolerate shade. They adapt to sand, clay or serpentine soils. Butterflies also are attracted to the flowers in the summer.

These are just a few great natives to plant in your garden. Other native plants for the winter garden are Pacific wax myrtle, Strawberry tree and Red-twig dogwood.  

By choosing plants that are native to our region birds spend less energy and time foraging for food as they more easily recognize them as a food source. You can have your beautiful berries and color and the birds can eat them, too.
