• Cover vegetable plants with bird netting to keep quail and other birds away.

• Broadcast wildflower seeds and annual ryegrass on hillsides to stop erosion and give you lots of flowers next spring.

• Spray citrus and other tender plants with Cloud Cover to give them some protection from frosts.

• Plant Paperwhite Narcissus in pots for Christmas gifts.

Reds and Yellows Galore

What a beautiful fall we are having and what a fine opportunity to choose shrubs and trees that will decorate your garden each year with their bright, warm colors.

Some unusual shrubs are showing their colors right now. Fothergilla ‘Mount Airy’ is a deciduous shrub that grows 4-5’ tall and is prized for its profuse spring flowering of bottlebrush-like spikes of fragrant white flowers, and excellent yellow, orange and red-purple fall color.

Smoketrees, Cotinus coggygria, are multi-stemmed shrubs that grows 10-15’ tall. After the flowers they are covered with fluffy, hazy, smoke-like puffs. In fall the bluish-green leaves turn bright red. The variety ‘Royal Purple’ has dark purple leaves throughout the summer and fall.

Spiraeas are a large family of shrubs with tiny flowers in clusters. The spring-blooming varieties, like ‘Bridal Wreath’, have long arching branches covered with delicate white flowers. In the fall they are again colorful as the leaves turn a red-orange-yellow fall color.

We have many fine trees to choose from for fall color. Start with the Japanese maples, small trees that are beautiful in every season. Depending on the variety, leaves may turn to bright yellow, soft apricot, or brilliant scarlet. Look for trees now that provide you with just the look that you want.

Ginkgo is commonly called maidenhair tree, which refers to the resemblance of the fan-shaped leaves to maidenhair fern leaflets. In fall the leaves turn bright golden yellow leaves and are spectacular when backlit by early morning or late afternoon sun. The leaves drop all at once forming a golden carpet around the tree.

Some of our edible plants in addition to producing delicious fruit, will also add color to your landscape in the fall. Blueberries are deciduous shrubs that typically grows 5-8′ tall. After you enjoy their nutritious berries in the summer, you can watch their leaves turn attractive shades of red in the fall.

Pomegranates celebrate the end of the season with their bright yellow leaves – a nice contrast to dark green evergreens. Currant bushes, particularly the Crandall black currant, have now turned a soft, orange-red.

Persimmon trees come into their own in the fall. Their spectacular bright red to orange fall color is followed by orange ripening fruit that hangs majestically on bare branches into late fall.

Even the peach trees are attractive right now. Their light green leaves have taken on a soft pinkish hue. Some plum trees, like Satsuma and Burbank, as well as the tasty Pluots, turn shades of red, yellow and orange.

And don’t forget the beautiful grapevines for colors from bright yellows to intense reds.

Dress up your garden with the bright reds and yellows of shrubs, trees and edible plants.

• Crocus and daffodils announce the arrival of spring if you plant them now. Choose from a variety of colors and bi-colors available now.

• Enjoy birds in your garden by hanging bird feeders around the yard. You’ll see many different kinds as they migrate through this fall.

• Mulch asparagus beds with three inches of well-rotted manure.

• Japanese maples and snowball bushes are some of the most colorful shrubs in the fall. Plant them now and give them a head start on spring.

• Check houseplants for insects. Spray leaves with insecticidal soap and wipe them off to leave them clean and insect-free.

Protecting Plants from Freezing Weather

Plants vary in the amount of cold that they can take in the winter time. Where zinnias are completely killed by a frost, pansies thrive in the cold and will even bloom underneath the snow. Some evergreen shrubs, like jasmine vines, fuchsias, citrus and fragrant rhododendrons, are damaged by severe winter cold, but there are measures you can take to protect these plants.

Protecting plants from frost damage usually is accomplished by trapping the heat that is rising up from the ground with clear plastic or similar materials, by moving the plant to a sheltered location, or by spraying with an antitranspirant spray, such as ‘Cloud Cover’. Each measure gives a few degrees of protection, so try them all on tender plant you value.

Covering tender plants with plastic or ‘N-Sulate’ (a lightweight fabric) make a big difference. When covering with plastic, it is best to make a light frame and staple the plastic to it. If plastic touches the leaves, each point of contact will freeze. During the day, the covering must be opened, at least a slit, to prevent overheating. With just an hour of sun, temperatures under a closed cover can quickly rise to over 100 degrees!

For additional protection, add Christmas tree lights inside the cold frame. On extra cold nights, placing an aluminum space blanket over the plastic on the frame will significantly add to the frost protection. With the aluminized side placed down (towards the plants), a space blanket retains 99% of the heat.

‘N-Sulate’ is a floating row cover that traps heat and moisture underneath it. Temperatures beneath the fabric can be 6 to 8 degrees warmer than the outside temperature. It is light enough that you can simply drape it over the plant, and porous enough that you don’t need to remove it during the daytime. But it will need to be secured against winds.

‘Cloud Cover’ is a product made from an acrylic polymer. When sprayed on a plant, it forms a clear, colorless, flexible, glossy film that doesn’t interfere with the plant’s growth. ‘Cloud Cover’ forms a protective coating, holding in moisture on plant foliage and stems, substantially reducing water loss in winter when drying winds and frozen ground deprive plants of their natural moisture intake.

For winter kill protection, spray in late fall when the temperature is above 40 degrees. The spray will gradually break down in about four months under cold weather conditions.

Antitranspirants are also effective on cut Christmas trees, wreaths, and greens to retard needle drop by retaining moisture in the foliage.

Keeping plants well-watered is important in freezing weather. Container plants are especially vulnerable to the desiccating (drying out) effects of freezing temperatures.

Apply protection measures this month before the severe cold of winter arrives.
