Pacific Northwest Gardening Calendar (Zone 8a–8b)
How to Use the Garden Calendar
Gardening in the Pacific Northwest follows a rhythm shaped by cool springs, long stretches of rain, and soil that warms slowly in early season. What works in other parts of the country often runs weeks ahead of us here.
This calendar is designed specifically for Pacific Northwest gardens — especially Zone 8a and 8b — where timing matters more than dates on a seed packet. Instead of rigid planting charts, you’ll find seasonal cues, soil temperature awareness, and practical monthly guidance based on real regional conditions.
Use it as a reference point throughout the year. Conditions shift, but the rhythm stays consistent.
June
Early summer abundance. The garden shifts from planting mode to tending mode.
Plant
- More beans (succession)
- Basil (outdoors once nights are mild)
- Late carrots for fall harvest
- Second sowing of beets and chard
Do
- Harvest frequently to keep plants producing
- Water deeply and less often (train roots downward)
- Pinch/prune tomatoes lightly for airflow
- Mulch again where soil is showing
Watch
- Bolting lettuce as days heat up—switch to shade/heat-tolerant varieties
- Aphids and ants teaming up
- First signs of powdery mildew (improve airflow early)
Indoors / Protected
- Start: fall brassicas (late June for planting out mid-summer)
- Start: more basil if you love pesto season
