✨ Pull garlic, push carrots, baby the tomatoes through the Fourth of July sizzle.
Sowing fall carrots in Portland this July is the move I make every year right between the garlic harvest and the first real tomato glut. The dry stretch ahead (zero rain in the forecast and a Saturday flirting with 85°F) means I'm building a careful seedbed, not just scattering seed and hoping. While I'm out there, I'm also pulling garlic, tucking in beet rows, and babying the tomatoes against blossom end rot.
This Week's Action List
- 1
Direct sow carrots now for an October harvest. I like 'Napoli' and 'Bolero' for fall sweetness. Soak the bed deeply the night before, sow shallow (about a quarter inch), then cover the row with a board or damp burlap for four to five days until germination. With highs hitting the upper 70s and no rain coming, that surface crust will kill a carrot sowing in 48 hours if you skip this step.
- 2
Sow beets ('Detroit Dark Red' or 'Chioggia') in the same window, half an inch deep, two inches apart. Soak the seed clusters in water for an hour before planting to speed germination, then water the row lightly every morning until you see true leaves. Beets are far more forgiving than carrots in July heat but still need a consistent top inch of moisture.
- 3
Pull garlic this week if the lower three leaves have gone yellow and brown. With Saturday's 85°F and bone dry soil, you want to lift now rather than let the wrappers rot or split. Loosen with a fork, brush off soil (do not wash), and cure in a shaded, airy spot — my garage with a box fan works fine for two to three weeks.
- 4
Deep water tomatoes twice a week, not daily. Aim for one to two gallons per plant at the base, early morning, to keep calcium moving and prevent blossom end rot. The swing from Tuesday's 64°F to Saturday's 85°F is exactly the kind of week that triggers blossom end rot on 'Early Girl' and paste varieties — consistency is everything.
- 5
Slip in a quick succession of chard ('Bright Lights' or 'Fordhook Giant') and a fall kale ('Lacinato' or 'Red Russian') this week. Both germinate fine in warm soil if you keep them shaded and damp for the first week. These bridge the gap between summer salads and the heavy fall harvest, and they will still be producing in December for me here on the east side.
Frequently Asked Questions
When should I plant fall carrots in Portland Oregon?
I sow my fall carrots in Portland from late June through about July 20, aiming for harvest in October when frost sweetens the roots. After July 25 in Zone 8b, germination is still fine but the roots may not size up before short days slow growth in late September.
How do I know when to harvest garlic in Portland?
Pull garlic when the lower third of the leaves have turned brown but the upper leaves are still green, which usually lands between July 1 and July 20 in Portland. If you wait until all the leaves brown, the bulb wrappers split in our dry July soil and the cloves will not store well through winter.
