This is the best month for planting woody shrubs, trees and herbaceous perennials. Our year-round garden centers are well stocked with great plant selections. Remember, fall is for planting!

FOR FRESH COLOR

October is the prime month to plant spring-flowering bulbs like tulips, daffodils, crocus, hyacinths, and more. If summer flower pots are beginning to fade, replant with pansies, violas, and ornamental cabbage and kale. Add a few pots of chrysanthemums or asters and a straw bale with pumpkins or gourds to create a fall harvest feel.

FOR THE LAWN & LANDSCAPE

Avoid cutting back ornamental grasses, Black-eyed Susan plants, and others with late season seed heads to leave them for the birds. If done blooming, cut roses back to chest height to reduce damage from fall and winter winds. Place mulch over roots of roses, azaleas, rhododendrons, and berries after a hard frost for winter protection; this is usually best done late in the month.

Save seeds from the vegetable and flower garden. Dry, date, label, and store in a cool and dry location.

To suppress future pest problems, clean up annual flower beds by removing diseased plant material. Monitor landscape plants for problems, but don't treat unless a problem is identified. Remove and dispose of windfall apples that might be harboring apple maggot or codling moth larvae. Rake and destroy diseased leaves (apple, cherry, rose, etc.), or hot compost diseased leaves. If moles and gophers are a problem, consider traps or repellants such as Bonide MoleMax.

Fall is the best time to seed and feed your lawn. The warm temperatures of the soil kickstart the germination process and the cool air temperatures allow the root systems to grow dense and strong. Cool temperatures also reduce insect and disease problems. One thing to remember when seeding your lawn is to keep the seeds moist, otherwise the seed will die. A simple thin layer of G&B Soil Building Conditioner and the fall morning dew will help keep them moist and growing strong. Most successful lawns are started by October 15th to give young grass time to harden off before winter.

Test your soil with a home test kit or contact the OSU Extension Service for a local soil-testing company. Amend soil to correct deficiencies and improve as needed.

Plan for winterization of your irrigation system; our knowledgeable landscape professionals can make it easy, email us or call 503.777.7777 to schedule an appointment.

FOR THE EDIBLE GARDEN

Edibles to plant this month include garlic (bulbs), fava beans, overwintering onions, and shallots.

Sow cover crop seeds in empty garden beds to improve and protect the soil through winter. Dig and divide rhubarb every 4 years, then replant and mulch with manure or Harvest Supreme Premium Soil Amendment. After frost, cover asparagus and rhubarb beds with a mulch of manure or Harvest Supreme Premium Soil Amendment. Prune out dead fruiting canes in raspberries; train and prune primo canes. Spray apple and stone fruit trees at leaf fall (dormant spray) to prevent most fungal and bacterial diseases.

IN THE GARDEN SHED

To force Christmas cactus to bloom in late December, reduce water, place in a cool area (50-55°F), and increase time in shade or darkness (12-14 hours) in early October. Place hanging pots of fuchsias where they won't freeze; don't cut back until spring. Check/treat houseplants, tender plants, and tropical succulents for disease and insects before bringing indoors.

Clean, sharpen, and oil tools and equipment before storing for winter. Store garden supplies and fertilizers in a safe, dry place, out of reach of children, pets, and other critters.

BASIC PRUNING

(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, as well as branches that may be damaged or cause damage from winter wind or snow and ice.

FOR FUN

Make a fall arrangement using pumpkins or gourds; cut the top off and carve a pumpkin to use as a temporary planter for some seasonal color or create an un-cut succulent pumpkin. Don't forget to check our upcoming classes and workshops!
