 | | | The Merrill Fire burnt to the back fences of houses in Moraga, Photo Cynthia Brian | | | | | | "Starry, starry night Flaming flowers that brightly blaze
Swirling clouds in violet haze." - Don McLean
In 1889, post-impressionist Vincent Van Gogh painted one of his most memorable paintings, "The Starry Night," as he looked out of his asylum east window. On Oct. 10, when I looked out our east window, the starry night was aglow with flames and they were not the brightly blaze of flaming flowers. Normally, I look forward to October because of the frivolity of Halloween - costumes, candy, scarecrows, black cats, ghosts, ghouls, jack o'lanterns, and trick or treating offer children a scary evening of amusement. It was a scary, scary night, but it was not Halloween.
The power was off and a fire erupted racing down the hill to a neighborhood fast asleep. Firefighters were swift and efficient evacuating the community and containing the inferno. Police officers assisted in maintaining peace and safety. Fortunately, all structures were saved and no injuries were incurred, thanks to the professional first responders. Gardens and landscapes survived the blaze with only a few fences being torched.
What homeowners need to know to be more fire-safe:
Lamorinda is rural, wooded, with minimal escape routes. Many of the plants and trees growing throughout our area are highly flammable including pines, cypress, cedar, fir, bamboo, acacia, juniper, Pampas grass, rosemary, ivy, arborvitae, miscanthus, and eucalyptus. Coyote brush, although moderately fire-resistant when it is young and green, is highly combustible as it grows. It depends on fires to regenerate and grows everywhere in our hills. All of these plants need to be removed or carefully supervised. Since heat moves up, fire speed and severity is stronger on slopes where vegetation management is crucial.
Autumn is a prime time to prepare your landscaping for the next season and create a defensible space around your property. A defensible space is an area around a structure that has been cleared of ignitable debris and botanicals that may cause a public safety hazard. No plant is fireproof. Under the right conditions, every plant will burn, especially those that are drought-stressed or not maintained. A "fire-safe" plant means that it tends not to be a significant fuel source in itself with a chemical composition that resists heat and combustion. It is critical to keep plants around our homes well tended and pruned as a fire protection tool. The closer plants are to the house, the more care is needed. Every homeowner is responsible for managing their vegetation to meet fire district requirements.
Neighborhoods are encouraged to form a committee to receive advice from local fire professionals on how to be Firewise. Being Firewise is dependent on the diligence of everyone in a neighborhood to keep property fire safe. Fires do not honor property lines. All properties become indefensible when one neighbor has overgrown bushes, brush, or low hanging trees.
What makes flora highly flammable?
- Dry and dead leaves, twigs, branches
- Abundant, dense foliage
- Needles
- Low moisture foliage
- Peeling, loose bark
- Gummy sap
- Leathery or aromatic leaves
- Content of terpene, oils, or resin
- Dry uncut grasses
What makes flora reasonably fire-resistant?
- Hardy, slow-growing plants that don't produce litter or thatch.
- Drought tolerant natives with internal high water content. Generally,
but not always, California natives are more tolerant of fire and deer.
- Trees with thick bark that restrict the growth of invasive shrub species and hardwood trees such as walnut, cherry, maple and poplar are less flammable. Deciduous trees and shrubs are more fire resistant because they have higher moisture content when in leaf, lower fuel volume when dormant, and usually do not contain flammable oils.
- Supple, moist leaves with little to no sap or resin residue.
- Low growing ground covers.
- Bulbs with dried leaves cut to the ground.
What can you do now to create a more fire-resistant landscape?
- Include pavers, bricks, pavement, gravel, rocks, dry creek beds,
fountains, ponds, pools and lawns.
- Select high moisture plants that grow close to the ground with a low
sap and resin content.
- Plant the right plant in the correct location. Leave space between plants.
- Minimize the inclusion of evergreen trees within 30 feet of structures.
Clear the understory. Keep trees 20 feet away from chimneys.
- Remove invasive species or swaths of flammable plants including ivy,
rosemary, broom, coyote brush, chamise, and juniper.
- Keep mulch moist. Create zones of rock, brick or gravel. Bark and leaves
are not mulches recommended near structures.
- Prune trees 6-10 feet above the ground to hinder fire laddering.
- Keep appropriate clearance to reduce the threat of burning embers from
decorative features such as gazebos, fences, sheds, porches and
junk areas.
- Irrigate and maintain all flora, lawns, and hillsides. Clover,
ground covers, and grasses that are kept low and green are excellent
alternatives.
- Due to soil erosion, bare ground is not recommended.

Having had warning of the looming PG&E blackout, I had deeply irrigated my entire garden and hillside. An alert from EBMUD instructed that in a power outage, water must be used judiciously, so as a preemptive measure, I watered my landscape thoroughly, soaking the grass, shrubs, mulch, trees and fences. Throughout the summer, thrice, I had weed-whacked the tall grass surrounding my property and that of neighbors, pruned low hanging tree branches, and a week before the fire I had, thankfully, cut the dry perennials to the ground. These are steps I encourage all homeowners to undertake. Maintaining our landscaping is a never-ending task mandatory for both our pleasure and protection.
Let's participate in keeping the fire-breathing dragon away. Enjoy a safe and scary evening of Trick or Treating under the starry skies!
Happy Gardening. Happy Growing. Happy Halloween! |
