What to plant this week in Salem, OR
With Salem's mild 8b climate holding steady above 15°F, you are in the thick of peak summer harvests from March frost through late December. This week marks a critical window to pull your early crops like bush beans and cucumbers before heat stress sets in, while simultaneously sowing warm-season giants like okra and Malabar spinach that thrive in our coastal fog influence.
The next 7 days

- Our Willamette Valley clay-loam soils stay cool deep down; break up hard-packed beds now to let air circulate and prevent root rot on heavy feeders like squash and zucchini.
- Salem's notorious afternoon summer fogs can stall pollination for cucumbers and beans; use bumblebee pollinators or hand-pollinate if you notice empty blossoms despite active bees.
- Avoid overhead watering during our humid nights to combat powdery mildew, which loves the damp air common in the Willamette basin this time of year.
- Take advantage of our long daylight hours by starting your late-summer succession plantings of scarlet runner beans and summer savory directly into warm soil today.

Seasonal tips
- Succession sow bush beans and pole beans every two weeks for a continuous harvest through summer.
- Thin out dense seedlings of zucchini and yellow summer squash to prevent overcrowding.
- Apply a light layer of mulch around established crops to retain soil moisture as summer heat builds.
Pest & disease watch
- Spider mites are exploding on tomatoes and peppers as humidity fluctuates between our dry inland winds and wet coastal air.
- Aphids are currently swarming the new growth on French marigolds and nasturtiums, using them as a 'sponge' for excess moisture before moving to crops like basil.
- Slugs and snails are active in Salem's moist garden beds right now, targeting young Malabar spinach leaves just before they bolt.
Watering this week
Water deeply at the base of plants in the morning to keep foliage dry and reduce disease risk during hot days.
Harvest watermelons when they produce a hollow sound upon tapping, indicating full ripeness.
Salem gardening questions
3Can I still start zucchini or squash seeds outdoors in Salem this week?
Yes, our 8b zone soil has warmed enough for direct sowing of yellow summer squash and zucchini today. However, protect these heavy feeders with row covers initially to shield them from the sudden coastal wind gusts common near the Willamette River.
My basil is bolting early; should I cut it back or replace it?
Since Basil is listed for both sowing and harvest soon this week, pinch off any flower buds immediately to encourage leafy growth. If your plants are already heavily seeded out, transplant a new Thai Basil seedling into the spot today to extend your season before our first late frost in December.
Are we safe from late frosts if I plant Malabar Spinach now?
Absolutely; Salem's average last frost is March 1st, and this hardy leaf green tolerates light freezes well. Sow the seeds directly into your bed today to ensure a robust harvest as the weather stabilizes for our remaining growing season.
