FOR FRESH COLOR

Pot up and store tulips and daffodils to force into early bloom indoors in December and January.

Plant paperwhites and amaryllis; you’ll see flowers opening in 4-6 weeks for paperwhites; 6-8 weeks for amarylli. For an extended bloom time, continue to pot them up about every 2 weeks while supplies last.

There’s still time to plant garlic and spring flowering bulbs, but don’t wait too long!

Get pansies and violas planted soon so they can develop enough roots to thrive all winter. Add ornamental cabbage/kale or grasses and coral bells for evergreen accents.

FOR THE LAWN & LANDSCAPE

Cooler weather and plentiful rain make this an ideal planting time for trees and shrubs. Evaluate your garden’s need for evergreens or plants with winter interest. Cruise through our garden centers for ideas and inspiration. Continue to plant and transplant until the end of this month.

Keep controlling the slug population with traps or baits; Sluggo is all-natural and safe to use around edibles, pets, and kids.

Trim chrysanthemums to 4-6 inches tall after they finish blooming; hardy varieties will return in the spring. Once spring growth resumes, pinch mums back by about 1/3 every 2 to 3 weeks until around the 4th of July; this causes the plant to branch with many flower buds that will open late summer or fall.

Allow ornamental grasses to stay up for the winter to add texture to your garden as well as food and shelter for birds and wildlife; trim them back in early spring before new growth begins.

Protect tender evergreens and new plantings from drying wind by spraying an anti-transpirant product like Moisture Loc or cover with Harvest Guard.

FOR THE EDIBLE GARDEN

Harvest fall turnips, lettuce, and spinach; mulch garden after a hard frost. Plant garlic and shallot bulbs now for summer harvest. Use Malibu Compost and G&B Starter Fertilizer with bone meal.

Plant blueberries, cane berries, and fruit trees this month to take advantage of cool, rainy weather. Amend soil with compost to improve drainage if planting in heavy clay.

Be ready with cold frames and frost protection cloths; protect tender greens and fall crops from heavy freezes.

It is the last chance this season to plant cover crops for soil building. You can also use a 3- to 4-inch layer of leaves spread over the garden plot to eliminate winter weeds, suppress early spring weeds, and prevent soil compaction by rain.

Treat peaches four weeks after leaf fall; spray for peach leaf curl and shot hole diseases, using Bonide Copper Fungicide.

IN THE GARDEN SHED

Treat mossy roofs during dry spells with Moss Max by Bonide.

Mossy lawns may need improved drainage; possibly an application of lime (do a pH test to confirm). Bonide’s Moss Max Lawn Granules can control existing moss in lawns and help them green up quickly. If major drainage improvements are needed, call our landscape department to talk with someone from the water management team.

Clean and oil your lawnmower; service as needed. Clean and sharpen tools before storing for winter. Drain and store hoses before freezing temperatures arrive.

Burn off those extra Thanksgiving calories by mulching your garden beds after a frost. We love to use Soil Building Conditioner as our mulch of choice. Make sure not to pile mulch too close to the stem, trunk, or crown of plants.

BASIC PRUNING LIST

Autumn (September to mid-December)

  • Thin shrubs and trees only as needed (any other pruning may result in new growth that won’t harden off before winter)
  • Remove any dead branches from trees and shrubs as needed
  • Remove branches that may be damaged or cause damage from winter wind or snow/ice
  • Cut roses to waist- or chest-high to reduce winter damage from wind and snow/ice

FOR FUN

Create a holiday centerpiece or Thanksgiving table arrangement by cutting things from the garden. Look for colorful berries and seed heads, leaves with vibrant fall color, and stems of greens to add texture and bulk to the arrangement. Beautyberry and fall-blooming camellias are two of our favorites!

Visit the Portland Japanese Garden, Lan Su Classical Chinese Garden, and Hoyt Arboretum to see blazing fall colors and get inspired for future plantings.
