January Planting in the PNW

January is not about planting outdoors in the Pacific Northwest. It’s about buying time.

Our springs are cool, wet, and slow to warm, so seeds started too late often stall. 

Seeds started thoughtfully now have time to develop strong roots and steady growth before ever touching cold, wet soil. When spring finally shows up, those plants are well established and thriving. January is the season where gardeners who understand this region gain an advantage by starting early.

Think of January as the foundation season. You’re not chasing fast results. You’re setting the stage for healthier plants, steadier growth, and more abundant harvests later on, with far less stress along the way.

Top 10 Plants to Start in January 

1. Onions (from seed)

Difficulty: Easy, but slow

Best start: Indoors in shallow trays

Why January: Onions need a long runway to form proper bulbs

Next step: Transplant outside in early spring

They look like grass for weeks but for most, this is one of the best January investments you can make.

2. Leeks

Difficulty: Easy, patient-required

Best start: Indoors

Why January: Very long growth cycle

Next step: Transplant deeply once pencil-thick

Leeks love the PNW climate and reward early starts with thick, sweet stalks later in the year.

3. Kale

Difficulty: Very easy

Best start: Indoors

Why January: Cold-tolerant and forgiving

Next step: Harden off and transplant early

Kale thrives in cool weather and keeps producing even when other plants sulk.

4. Cabbage

Difficulty: Moderate

Best start: Indoors

Why January: Early planting avoids summer pests

Next step: Transplant once sturdy

Cabbage likes consistency. January starts mean spring harvests before the real slug chaos begins.

5. Broccoli

Difficulty: Moderate

Best start: Indoors

Why January: Long maturity time

Important note: Needs hardening off

PNW broccoli does best when it matures before heat stress. Early starts help immensely with this.

6. Lettuce

Difficulty: Easy

Best start: Indoors or cold frame

Why January: Cool-season favorite

Next step: Succession sowing

Lettuce is a confidence booster and an excellent way to practice seed starting without pressure.

7. Spinach

Difficulty: Easy

Best start: Indoors or cold frame

Why January: Thrives in cool temps

Important note: Bolts once it heats up

Spinach prefers the moody weather we’re famous for. Give it an early start and enjoy it before summer arrives.

8. Parsley

Difficulty: Moderate

Best start: Indoors

Why January: Very slow germination

Tip: Be patient — it can take weeks

Parsley pretends nothing is happening, then suddenly explodes with growth later. Totally normal.

9. Medicinal Herbs

Difficulty: Easy to moderate

Best start: Indoors

Includes: Chamomile, Calendula, Yarrow, Lemon Balm

Why January: Slow growers with big payoff

These plants are resilient, useful, and well-suited to PNW conditions. They’re not just pretty — they’re practical.

10. Lavender

Difficulty: Moderate

Best start: Indoors with cold treatment

Why January: Benefits from early or cold stratification Important note: Needs excellent drainage

Lavender takes its time but becomes a long-lived, low-maintenance staple once established.

Even though the internet loves to suggest otherwise, most PNW gardeners should wait on:

  • Peppers

  • Squash

  • Beans
