November Gardening Tips and To-Dos for the Pacific Northwest

The rain is back. The days are short enough that I’m turning on lamps by four, and the bay out front has gone from summer blue to that soft November gray. The garden isn’t done yet, though. It’s just quieter.

November is the month for tucking things in. A few hours of work now (mulching beds, digging or protecting dahlias, draining the irrigation lines) save real headaches in February. And the bulbs you plant this month are the daffodils and tulips you’ll be cutting in March and April.

Here is my November garden-to-do list for the Pacific Northwest, written from our Zone 8b cottage garden on Puget Sound. If you missed last month, start with my October gardening tips for the Pacific Northwest.

Quick November Garden Checklist for the Pacific Northwest

Short on time? These are the tasks that matter most this month:

  • Plant tulips, daffodils, and garlic before the ground gets waterlogged
  • Decide whether to dig up or mulch your dahlias
  • Spread shredded leaves or mulch over bare soil
  • Drain irrigation lines and cover outdoor spigots before the first hard freeze
  • Move tender plants like geraniums into the greenhouse or a bright window
  • Clean gutters and check that winter rain drains away from beds
  • Clean, sharpen, and oil your garden tools
  • Order seed catalogs and start your wish list

A Quick note about my garden

  • Location: Pacific Northwest; about 60 miles southwest of Seattle, Washington
  • Growing Zone: USDA Zone 8b
  • Average Last Frost: Mid-April (give or take a little PNW spring moodiness)

Most of the flowers I share here are grown from seed in our greenhouse and planted in raised beds and containers throughout our cottage garden.

What to Plant in November in the Pacific Northwest

Finish Planting Spring Bulbs

In our mild maritime climate, you can keep planting spring bulbs well into November. Tulips actually do better planted a little later here, once the soil has cooled. The real deadline isn’t frost. It’s when the beds turn to soup.

  • Plant tulip bulbs 6 to 8 inches deep, pointy end up.
  • Choose beds with good drainage. Bulbs sitting in cold, soggy soil all winter will rot.
  • If your beds are already saturated, pot bulbs up in containers and tuck them against the house.

For the full rundown on bulb care after they bloom, see Growing Tulips from Bulbs.

Plant Garlic

Plant garlic now so it can grow roots over winter. Separate the cloves right before planting, set them 2 inches deep and 6 inches apart, and cover with a light layer of straw or shredded leaves.

Order Bare-Root Roses, Fruit Trees, and Shrubs

Order bare-root plants in November while the best varieties are still available. Most nurseries ship them from January through March, which is when they should go in the ground here. Ordering early means you get first pick.

Take Hardwood Cuttings

Once leaves drop, you can take hardwood cuttings from hydrangeas, roses, and other woody shrubs. Cut pencil-thick stems about 8 inches long, just below a leaf node, and stick them in a pot of gritty soil in a sheltered spot. Some will root by spring and some won’t. That’s fine. Take more than you need.

How to Protect Dahlias and Tender Plants Over Winter

Dig or Mulch Your Dahlias

In Zone 8b, the cold usually isn’t what kills dahlia tubers. Wet soil is. A tuber sitting in waterlogged ground from November to April can rot.

  • Dig them up if your soil is heavy or drains slowly, or if you have varieties you can’t stand to lose. Wait until frost blackens the foliage, then follow my steps for storing dahlia tubers over winter.
  • Leave them in the ground only if the bed drains well. Cut the stems back and add mulch.

I personally leave my dahlia tubers in the ground through the winter with a layer of mulched leaves on top to protect them from winter temperatures.

Bring Geraniums and Tender Plants Inside

Geraniums, fuchsias, and other tender perennials need to come in before the first hard freeze. Mine spend the winter in the greenhouse. A bright, cool window works too. Here are 4 easy ways to overwinter geraniums, depending on how much space you have.

November Greenhouse Tasks

The greenhouse changes jobs in November. It stops being a growing space and becomes a winter shelter.

  • Clean out spent summer plants and sweep the benches before moving tender plants inside.
  • Wash the glass or panels. Winter light is precious, and dirty glass blocks more of it than you’d think
  • Test your heater and thermostat before you need them.
  • Crack a vent on mild days. Our damp air plus cold nights mean condensation, and condensation invites gray mold.
  • Water overwintering plants sparingly. They’re resting, not growing.

Fall Garden Cleanup: What to Cut Back and What to Leave

You don’t need a perfectly tidy garden when heading into winter. Your garden soil and beneficial insects benefit from some mess.

Clean Up

  • Pull spent annuals and vegetable plants and add healthy material to the compost.
  • Remove anything diseased (mildewed zinnias, blighted foliage) and put it in the yard waste bin, not the compost.
  • Pick up fallen fruit to avoid pest and disease problems.
  • Finish weeding while the soil is soft and roots pull out easily.

Leave Standing

  • Seed heads on rudbeckia, echinacea, and sedum feed the birds and look pretty in frost
  • Hollow stems shelter native bees over winter
  • Evergreen perennials and ferns can wait until late winter. See how to cut back evergreen ferns

Watch for Slugs

Mild, wet November weather is slug season in the Pacific Northwest. Check under boards and pots, and protect anything newly planted. A little slug control now means fewer eggs hatching in spring.

Mulch Garden Beds with Fallen Leaves

Fallen leaves are free mulch, and we have plenty of them. Bare soil gets pounded and compacted by winter rain. A layer of shredded leaves protects it, feeds the earthworms, and breaks down into rich organic matter by spring.

  • Run the lawn mower over leaves to shred them. Whole leaves can mat down and smother plants
  • Spread 2 to 3 inches over beds, keeping it a few inches away from stems and crowns
  • Add a thicker layer over borderline-hardy perennials for frost protection

Winterize Irrigation, Hoses, and Drainage

Frozen pipes are no fun in January. Take care of them now while it’s still mild.

Irrigation and Hoses

  • Drain drip lines and irrigation systems, and shut off outdoor valves
  • Disconnect hoses, drain them, and coil them in the shed or garage
  • Cover spigots with insulated foam covers
  • Bring timers and battery controllers indoors

Gutters and Drainage

  • Clear leaves and needles from gutters and downspouts
  • Make sure downspouts send water away from the house and garden beds
  • Walk the garden after a heavy rain and note where water pools. That tells you where not to plant bulbs or leave dahlias next year

Clean and Store Garden Tools

A little maintenance now saves frustration in March.

  • Scrub off dirt with soap and water and dry thoroughly
  • Wipe pruner and snip blades with rubbing alcohol to avoid spreading disease
  • Sharpen pruners, shears, and mower blades
  • Oil moving parts and metal surfaces to prevent rust

Plan Next Year’s Garden

November Gardening FAQ for the Pacific Northwest

Is it Too Late to Plant Tulip Bulbs in November in the Pacific Northwest?

No. In Western Washington and Oregon, you can plant tulips through November and often into December, as long as the soil isn’t frozen or waterlogged. Tulips need 12 to 16 weeks of cold, and our winters provide that easily.

Should I Dig Up My Dahlias in Zone 8b?

It depends on your soil. Dahlias can survive Zone 8b winters in the ground if the bed drains well and is covered with 4 to 6 inches of mulch. In heavy or wet soil, dig and store them, since rot is a bigger threat than cold.

When is the First Frost in Western Washington?

Along Puget Sound, the first frost usually arrives between late October and mid-November, with hard freezes more common in December. Inland and higher-elevation gardens often see frost earlier.

Should I Cut Back Perennials in the Fall or Spring?

Both work. Cut back anything diseased or floppy now, and leave sturdy stems and seed heads standing until winter late winter. They feed birds, shelter beneficial insects, and protect the crown from cold.

Should I Leave Fallen Leaves in My Garden Beds?

Yes, ideally shredded. Shredded leaves protect the soil from heavy winter rain, feed earthworms, and break down into organic matter. Keep thick layers off the crowns of plants and off the lawn.

What Vegetables and Flowers Can I Plant in November in the PNW?

Garlic, spring-blooming bulbs (tulips, daffodils, alliums, crocus), and hardy perennials can all go in during November. Sweet peas can be fall-sown in milder coastal gardens, and bare-root plants can be ordered now for late-winter planting.

Final Thoughts

November is the last big push in the garden before the rain settles in for good. Plant the bulbs, sort the dahlia tubers, and drain the hoses. Then, cut a few berry branches, bring them inside, and let the garden rest.
