Put your Garden to Bed

 There’s a peaceful quality to this time of year.  Mother Nature is winding down for the season turning deciduous trees ablaze with fall color.  Cool season pansies and violas turn their little faces to catch the sun.  It’s time to put the garden to bed for a greener spring next year. 

 Here are some suggestions, but promise you won’t try to do everything on one weekend.  it’ll just seem like work.  Gardening should be something you enjoy. 

  • Build up your soil by layering the vegetable beds with 2" of leaves newly fallen from your trees.  Soil building worms and organisms will start their work right away.  In the spring, dig what’s left into the soil.  If you want the leaves to break down faster, run over them with a lawn mower, then rake them up for mulch.
  •  Prevent erosion of your precious soil by mulching with straw or bark.  Mulch used around perennials, shrubs and trees will help moisture percolate into the soil instead of running off into storm drains or creeks along with fertilizers.    Mulch also keeps the soil from becoming compacted by winter rains.  If you don’t have enough leaves to use as mulch try layering newspapers and cardboard and cover with straw.  3-4" of mulch around the base of trees and large shrubs will hold weeds down, too.  Be sure to keep mulch a couple of inches away from the base of your plants so trapped moisture doesn’t rot the trunk. 
  • Chop down leftover vegetable plants and spent annuals flowers and layer on the vegetable bed under cardboard to decompose.  Don’t do this with diseases plants such as squash plants with powdery mildew.   These can be put in the curbside yard waste can.  Hot commercial composting systems can kill disease spores.
  • Clean empty pots and store them upside down in a dry location.  That way you’ll keep any soil diseases from being passed on to next year’s plants. 
  •  Store any excess leaves to use next summer if you have a lot of deciduous trees.  They’re like gold.  They make great bedding for a worm bin and next summer you can use them in the compost pile when you have an abundance of nitrogen rich green material but little carbon-based brown stuff to mix with it. 
  • Leave a little debris for wildlife so beneficial ground beetles have a place to live and birds can snack on seeds left on shriveled flowers.  Coneflowers, ornamental grasses and crocosmia all attract birds to their seed heads through the winter. 

The bottom line is to do those fall clean-up jobs as you have the time and energy.  Cleaning up in increments leaves height and interest in the garden and feeds the birds, too.

What you should do first, though, is to bring indoors houseplants that  spent the summer out on the patio. Also bring in any plants too tender to survive the winter outside. Be sure to inspect them for insect pests and wash them off.   Sub-topical plants  like tree ferns and bananas benefit from extra mulch to help them survive the worst of the winter weather.

It’s not too late to reseed thin spots on your lawn or apply a fall fertilizer to an existing one and if you have citrus trees, rhododendrons, azaleas or camellias they’ll benefit from an application of   Citrus use it for flower bud development and fruit sweetness.  Rhodies, azaleas, and camellias need it when flower buds begin to form.  It also improves flowering and root development of any plant and helps plants resist diseases and cold weather damage. 
 

Let the Birds Control your Insect Pests

Looks like trick-or-treating for Halloween is as popular with my garden visitors as it is with kids.  No, I’m not talking about those four-legged twins with doe-eyes that look longingly through my deer fencing at my hydrangeas.  I’m referring to the many birds that flock to my garden to eat aphids, mealybugs, mites and spiders, keeping the insect population under control without me lifting a finger.   What could be more convenient and beautiful to watch?

Throughout the year there are many resident birds that help me in the garden as they go about their business of  nesting and raising their young.  Ladybugs and other beneficial insects also do their part but it’s the songbirds I depend on to really get in there and do a clean sweep.  As if that’s not enough I get to hear them sing and call to each other and enjoy their bright plumage as they flit through the trees.

My garden is not very big.  I have a small birdbath to provide water for drinking and bathing. Several hummingbird feeders supplement the food supply when they are feeding their young and to help them through the winter.  The plants I grow provide foliage, nectar, pollen, berries, seeds and nuts for all wildlife ( except those deer, sorry ) that visit my garden.  Shrubs provide hiding places and shelter for birds and other wildlife to raise their young, avoid predators and get out of inclement weather.   In return, they keep my garden healthy.  I’m getting a good deal, if you ask me.

Just this morning I was happy to welcome my resident flock of Chestnut-backed chickadees who proceeded to scour every perennial, shrub and tree like acrobats looking for insects and seeds.  They are quite tame and friendly and easily attracted to feeding stations.   At the same time, a group of brilliant yellow and black Townsend’s warblers arrived to survey the scene.  The prefer our cool fir and redwood forests in the fall and spring and also find food in oaks, madrones and bay trees.  These little birds are so bright you can see them from quite a distance.

Hopping about and scratching the ground to expose beetles and worms, a couple of American robins were doing their share of insect control. They also love the leftover blackberries still hanging on the vine.   Back up in the trees, the acorn woodpeckers were working on beetles and grubs hiding under the bark.  These are just some of the feathered help I have visiting my garden.

What can you do to encourage this free labor?  In addition to oaks and madrones, plant trees like crabapple, hawthorn, loquat, dogwood  and fruit trees for colorful fruits and berries.  Native shrubs like oregon grape, toyon, coffeeberry,  California wax myrtle, snowberry, coyote brush, manzanita and elderberry all have berries that attract birds. Ceanothus are among the most valued shrubs as a food source attracting bushtits, finches, grosbeaks, hummingbirds, mockingbirds, quail, thrashers, thrushes, towhees, warblers, white-crowned sparrows and wrentits.  Other shrubs to include are Japanese barberry, roses and junipers.

 Hummingbirds do their share of spider control when they have young and need extra protein.  Native plants like salvia, sagebrush, buckwheat, flowering currant as well as garden favorites like flowering maple, fuchsia, coral bells all provide nectar for them and butterflies, too.

 

 *  Avoid using chemical insecticides.   Most birds eat insects and spiders.  If you spray your plants with chemicals, you’ll create a sterile wasteland for protein-eating birds. You’ll also kill butterflies or their larvae.  Spray organic pesticides only if you absolutely have to and then direct the spray carefully. 

  *  Be unfastidious.  The best wildlife habitats are not overly manicured.  The less often you rake under bushes, the better it is for the birds.  Accumulated duff gives a place for insects and other creatures to breed and live.  When possible, leave small brush piles in out-of-the-way places.

If you’d like to identify the birds that you’ve attracted, you can get a free check list of the birds of Henry Cowell Redwoods State Park from their gift shop.  Many of those birds will be in your garden, too.  They also sell a beautiful laminated color chart of local birds of Monterey Bay area.  Fun to have by your kitchen window for a quick reference when you see a splash of yellow fly by.
