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 that 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 pots of flowers are beginning to fade replant with pansies, violas, and ornamental cabbage & 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 & 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 month.

To suppress future pest problems, clean up annual flower beds by removing diseased plant material, overwintering areas for insect pests; mulch with manure or garden compost to feed the soil and suppress weeds.

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.

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

If moles and gophers are a problem, consider traps or repellants such as Bonide MoleMax.

Fall is the best time to seed & feed your lawn. The warm temperatures of the soil kick start 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 Black Forest Compost and the fall morning dews will help keep them moist and growing strong. Most successful lawns will be started by October 15th to give young grass time to harden-off before winter.

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

Plan for winterization of you 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: garlic (bulbs), fava beans, overwintering onions, and shallots.

Sow cover crop seeds in empty garden beds to improve & protect the soil through winter.

Dig and divide rhubarb every 4 years, then replant and mulch with manure or Bumper Crop soil amendment. After frost, cover asparagus and rhubarb beds with a mulch of manure or compost such as Bumper Crop Soil Builder.

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 various fungal and bacterial diseases.

IN THE GARDEN SHED:

To force Christmas cactus to bloom in late December reduce water, place in 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.

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.

Check/treat houseplants, tender plants and tropical succulents for disease and insects before bringing indoors.

BASIC PRUNING:

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 and 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 take an un-cut pumpkin spray with craft glue, stick dried moss on top of pumpkin and glue cuttings of sedums and succulents onto the moss. Add colorful berries &/or seed pods as embellishments to finished arrangement; mist with water twice a week. Check our upcoming classes & workshops!
