Or: How to prepare your garden for a winter that may have absolutely no respect for your plans.
Hello, fellow dirt enthusiasts.
November has arrived on the Monterey Bay, and Mother Nature appears to be preparing something rather theatrical.
The weather people are talking about a very strong El Niño — possibly a Super El Niño. Whether that translates into biblical rainfall in your particular backyard remains to be seen. Our little corner of California has a remarkable talent for ignoring regional forecasts.
But there’s no sense waiting until your garden resembles a swamp and your wheelbarrow has floated into the neighbor’s yard.
Here’s your November assignment.
1. Sharpen Your Chainsaws. And Everything Else With an Edge.
Chainsaws, loppers, pruning shears, hedge trimmers. November is an excellent time to sharpen, clean, oil, and inspect your cutting implements.
Remove dead or damaged branches that might become airborne during winter storms. Check for limbs threatening fences, paths, and rooftops.
And while you’re feeling industrious, clear those gutters and drainage channels.
A word of caution: Storm-damaged trees, especially limbs under tension, are not amateur chainsaw projects. Call an arborist. Heroism is overrated, particularly when performed from a ladder.
2. Rake the Diseased Leaves. The Fungi Are Plotting Their Return.
Those spotted, rust-colored, mildew-covered leaves beneath your roses, peonies, and other susceptible plants aren’t merely untidy.
They’re potentially next year’s fungal infestation, patiently waiting for spring.
Rake them up, bag them, and send them to an appropriate disposal stream. Don’t toss infected leaves into your backyard compost pile. Most home compost heaps don’t get consistently hot enough to eliminate every troublesome pathogen.
Healthy leaves are another matter. They can become wonderful mulch, compost, and overwintering habitat for beneficial insects.
The goal isn’t a sterile garden. It’s a garden where the good guys have somewhere to live and the bad guys have fewer places to hide.
3. Poison Oak: Put Away the Sprayer.
If you’ve been planning a grand offensive against poison oak, you’ve probably missed the best window for foliar treatment.
As autumn progresses, poison oak sheds its leaves and moves toward winter dormancy. With photosynthesis and growth slowing, there’s much less opportunity for leaf-applied systemic herbicides to be absorbed and transported through the plant’s phloem into its roots.
In other words, you can’t effectively poison leaves that aren’t there.
Mark the offending plants and plan your next campaign when they’re actively growing and carrying healthy foliage.
And remember: leafless poison oak can still cause a spectacularly miserable rash. Never burn it, either.
Gardening requires patience. Occasionally it also requires admitting that the enemy has won this round.
4. Peonies: Time for Bed.
If your herbaceous peonies haven’t been trimmed back, and their foliage has yellowed or died, now is the time.
Cut the old stems close to the ground and remove the debris, particularly any foliage showing signs of fungal disease.
Peonies spend winter conserving energy underground, preparing for their next glorious performance.
Of course, along the immediate coast, peonies can be notoriously temperamental. They prefer a proper winter chill, something our Monterey Bay microclimates don’t always deliver.
Still, hope springs eternal. Especially among gardeners.
5. Mexican Sage: Don’t Evict the Hummingbirds.
Those magnificent purple-and-white Mexican bush sages are among the last great nectar buffets of the year.
And our hummingbirds know it.
Rather than cutting the whole plant to the ground in one heroic afternoon, consider pruning selectively over November, December, and January in our mild coastal gardens.
Remove spent flowering stems in stages while leaving healthy, nectar-rich blooms standing. In warmer spots, selective trimming may encourage fresh growth and another round of flowering.
In frost-prone gardens, leave more of the old growth for protection until spring.
The idea is simple: tidy the garden without shutting down the neighborhood hummingbird diner.
Our tiny feathered customers have remarkably high expectations and absolutely no interest in your landscaping schedule.
6. Roses: A Little Care, Not a Banquet.
Some Monterey Bay roses are still flowering in November, blissfully unaware that the rest of the country is preparing for snow.
If yours are actively growing, a modest application of an appropriate organic fertilizer may be reasonable in a particularly mild microclimate. But for most established roses, heavy feeding should be finished by now.
We don’t want to push a flush of tender new growth just as winter arrives.
Clear diseased foliage, refresh mulch, and save the major pruning of most repeat-flowering roses for winter dormancy.
And avoid reaching automatically for combination fertilizer-and-pesticide products. A hungry rose doesn’t necessarily need an insecticide.
Sometimes the best gardening intervention is to stop intervening.
7. Finally, the Most Dangerous November Gardening Activity: Catalog Shopping.
The newest seed, rose, bulb, and perennial catalogs are appearing.
Pour yourself something warm. Find a comfortable chair. Start imagining next year’s garden.
Perhaps a fragrant climbing rose. A ridiculous number of dahlias. A new salvia that will bring even more hummingbirds. Or that spectacular plant you’ve killed twice already but are convinced will succeed on the third attempt.
There is absolutely no scientific evidence that gardeners learn financial restraint from catalogs.
And isn’t that rather wonderful?
One Last Thought
November gardening isn’t really about making everything perfect before the rain.
It’s about knowing what to cut, what to clean, what to leave alone, and what to dream about next.
The fungi will return. The weeds will return. The hummingbirds will demand breakfast.
And somewhere beneath all that damp soil, next spring is already getting organized.
