July Planting Guide for Portland, OR: Raised Beds, Containers & In-Ground Gardens
In July, Portland gardeners can focus on heat-tolerant vegetables and herbs in raised beds, containers, and in-ground gardens.

FAQs
Can I plant lettuce in July in Portland?
It's best to start lettuce indoors in July for transplanting in late summer, as direct sowing outdoors may cause bolting due to heat.
How often should I water raised beds in July?
Water raised beds deeply about 2-3 times per week, adjusting for rainfall and temperature to keep soil consistently moist but not waterlogged.
Are tomatoes safe to plant outdoors in July?
Yes, transplanting tomato seedlings outdoors in July works well, but avoid direct seeding now as the season may be too short for fruit development.
What vegetables should I avoid planting in July in Portland?
Avoid planting cool-season crops like peas, carrots, and radishes outdoors as they struggle in summer heat and may not mature before frost.
How can I protect container plants from heat stress?
Place containers in partial shade during peak afternoon sun, water more frequently, and use mulch or self-watering containers to maintain moisture.
