November Tips & Events for Santa Clara County
"Love the trees until their leaves fall off, then encourage them to try again next year.”  Chad Sugg

Smoke
As people tried to protect their lungs from particulate matter in the smoke from the California fires, they asked about possible harm to their plants. It is true that these same particles can clog the plant stomata (“pores”), basically making it difficult for the plants to breathe. The particulate pollution can also coat the leaves, reducing photosynthesis through which the plant makes its own food. If plants appear dusty, you can reduce the physical effects of the particulate matter by rinsing off your plants with a hose.

Fire Safe Landscaping
There are steps you can take in your landscaping that might help protect your home and property. Clear brush around your house that might otherwise help a fire spread. Avoid high oil content plants like eucalyptus and juniper. And try planting succulents that hold more moisture inside.

Pretty Bugs
The beauty of a bug isn’t a clue to its usefulness in the garden. One attractive pest is the harlequin bug. This pest sucks on plant juices and can cause splotching of leaves and wilting of plants. It feeds on cool weather crops like cabbage, kale, and mustard. Handpicking the bugs and eggs and removing old plant material are good controls.

Straw
Can those bales of straw or hay that were used as Halloween decorations be recycled into your garden? Absolutely. It makes great mulch and can be used around plants to moderate soil temperature or used to cover a fallow area over the winter. It guards against weeds and erosion. It breaks down slowly, adding organic matter to the soil and feeding the beneficial organisms living in the soil. 

Frost
It seems we’re barely out of summer, yet the average first frost date in parts of Santa Clara County is as early as November. You may want to be prepared in advance so you—or, more importantly, your plants—don’t get hit by surprise. Some protective measures you can have ready are row covers, old cloth sheets, and space under the eaves for potted plants.
