Fall Tips for Gardeners

Halloween is just around the corner and besides deciding what your or the kids are going to be this year, it’s time to bring in any plants that you plan to overwinter in the house. Whether they’re the houseplants that you put out on the patio for the summer or frost tender plants that you want to save, this is the .

 Although our nights are still well above freezing,  plants need to acclimate to the indoor environment before you start turning on the heater regularly. Be sure to wash them thoroughly and inspect them for any insects that may have taken up residence while they were vacationing outside. Usually you can dislodge any hitchhikers with a strong spray of water but if that doesn’t do the trick, spray them with a mild insecticidal soap or one of the other mild organic herbal sprays like oil of thyme.

If you want to decorate for Halloween there is a lot of plant material you can harvest from your own garden or nearby woods. Manzanita branches can often be found on the ground and make great arrangements combined with nandina or other berries. Some of the trees have started to turn color and their leaves can also be used for wreaths.  The leaves of New Zealand flax last a long time and add fall color in bouquets.

Mums are the classic fall flower.  They come in nearly every color except blue and the flowers have many shapes from daisy to spider mums.  They are perennials and make good additions to the garden. Best of all they make excellent cut flowers.

This October has had the perfect weather  allowing fall color to develop in our trees, shrubs and perennials.  Warm days, cool nights, not a lot of wind or heavy rain all help plants to attain and keep those bright reds, oranges and yellow colors we love. Here’s a short list of small plants that you can easily find space for even in the smaller garden.

Japanese barberry turn yellow, orange or red. They get red berries and are deer resistant.
Blueberries not only are good for you and their foliage turns beautiful yellow-orange in the fall.
Oakleaf hydrangea leaves take on burgundy hues.
Crape myrtle shrubs explode with brilliant red and orange color.
Pomegranate bushes turn bright yellow
Spirea foliage varies from red, orange to yellow.

Squirrel wars
If you are at odds like me with squirrels that dig up everything while burying acorns for the winter, delay planting your bulbs until Thanksgiving when they’ve finished stocking the pantry.  Store you bulbs in the frig or a cool place until then.  If you just have to plant some on a beautiful autumn day, cover the area with flat stones or chicken wire.

Don’t prune now
One last thing and you’ll be happy to hear this.   Fall is not a good time to prune.  Wounds heal slowly, leaving them more susceptible to disease.  As a general rule, don’t prune when leaves are falling or forming.  Wait to prune most trees until late in the dormant season or  late spring after leaves and needles form.  To avoid sap flow on birches and maples, prune after leaves mature. 

What to Plant in Clay Soil in the Santa Cruz Mountains

              "The soil is made of butterfly wings, dinosaur teeth, pumpkin seeds, lizard skins, and fallen leaves.
                  Put your hands in the soil and touch yesterday, and all that will be left of tomorrow shall return
                                         so that new life can celebrate this day."  -Betty Peck

Soil is a wonderful thing. It grows our food, anchors our trees and provides a foundation under our feet. But it sure can be hard to work with if it’s not the soft, crumbly loam that many plants prefer. It’s amazing that anything grows in some of the soils here in the Santa Cruz mountains. Some folks garden in an ancient sea bed of sand and there are others who have such heavy clay in their gardens that you wonder how anything survives.  Recently I helped plant in the dense clay of Garrahan Park in Boulder Creek and I dedicate this column to those of you with similar inhospitable soils.

The soil in Boulder Creek required a pick ax to break up enough to plant. Sound familiar?  Although rich in nutrients it needed compost in many areas to provide the environment  necessary so beneficial microbes, worms and other critters could do their work and aerate the soil. A thick layer of mulch will be spread over the soil by The Boy Scouts to preserve the structure and prevent it from packing down again.

There are many plants that are tolerant of clay soils and plant selection is half the equation. The park chose mostly California natives that won’t need fertilization or pruning, can be eventually weaned from irrigation and will provide food for the birds and visiting children. Juncus, a type of grass, red-flowering currant, redtwig dogwood, California rose and western redbud will be the stars of the park in the wet, clay soil. The drier side of the park was planted with deer grass, toyon, California rose, huckleberry, coffeeberry , ceanothus, native honeysuckle, vine maple, native iris and California fescue grass.

I’m sure the park will be the crown jewel of the area and hopefully you will come to visit and see the progress of the plants. Kinda like a local demonstration garden in the San Lorenzo Valley.

There are plants from similar environments in other parts of the world that would also do well if you garden in heavy soil. One of my favorite trees for these conditions is the strawberry tree. Also hackberry, ash, gingko and paperbark trees work well also. Shrubs to try include flowering quince, bottlebrush, Australian fuchsia, smoke tree, escallonia, pineapple guava, mahonia, osmanthus, Italian buckthorn, elderberry and vitex. Easy perennials for clay soils are yarrow, bergenia, carex grasses, fortnight lily, coreopsis, echinacea, nepeta, salvia, teucrium and verbena to name just a few.

If you’re not familiar with some of these plants it’s easy to see what they look like by Googling images. It’s what I do to see a plant full grown and not just a line drawing or a close-up of the flower.

So you see, there are plants that will be successful even in heavy, clay soil, you just have to pick the right ones.

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.
