Pacific Northwest October Garden Checklist: Bulbs, Containers, and Harvest Extension

Fair-weather gardening means getting ahead in pleasant early autumn. October tasks set up winter ease and spring success.

Plant Spring Bulbs

Fun part first! October is prime for spring bulbs.

• Daffodils symbolize spring. Mass in drifts along pathways or tuck between late perennials (black-eyed Susan) to hide dying bulb foliage.
• Bluebells near hostas for shade garden effect.
• Match garden color scheme: white/silver/blue front garden repeated with white daffodils, white crocuses, periwinkle windflowers (Anemone blanda).

Plant Fall Container Gardens

Refresh with winter-hardy evergreen shrubs, perennials, seasonal color. Small conifers, bright spurge (Euphorbia), evergreen sedums, cheerful pansies. Add bulbs for spring layer: dwarf daffodils, hyacinths, crocuses. 'Princess Irene' tulips stunning with 'Peach Flambe' coral bells (Heuchera).

Shade containers: variegated Aucuba, coral bells, orange-tipped autumn fern (Dryopteris erythrosa), variegated grasses. 'Pink Frost' hellebore blooms months in pink shades; add snowdrop bulbs for partial shade.

Extend the Harvest

Brussels sprouts, parsnips survive harsh frosts. Cover tender lettuce, carrots with floating row cover (Harvest Guard) or cold frame. Remove summer crops (tomatoes, tender herbs). Remove fallen leaves under apple trees—especially if apple scab present. Do NOT compost; replace top inch soil with fresh compost to prevent fungal spread.

Generally Tidy Up

Cut soggy hostas and tired perennials/grasses, but leave coneflower (Echinacea) and grass seed heads for winter birds.

Divide and Multiply

Divide hostas, false spirea (Astilbe)—sharp spade works. Dig bearded iris, divide, replant with knuckles visible (over-mulching buried them too deep, reducing blooms).

Play in the Leaves

Leaves are nature's gift. Shred lawn leaves with mower; add to compost or back to garden as mulch. Don't cover perennial crowns (rot risk).

Make Composting Easier

Large garden = distant bins. Use wire cages behind evergreens or portable frames. Rake leaves in, let break down, spread rich mulch next year—saves double handling.

Enjoy the Season
