Gardening in Oregon - What to Plant in Spring & Fall

Having a productive garden in Oregon is easy to accomplish so long as you have the right plan. Below we’ll walk you through which plants thrive in Oregon, when to plant in Oregon, and how to adapt your garden as the seasons change.

Understanding Oregon Hardiness Zones

Hardiness zones, sometimes referred to as “growing zones” or “planting zones”, were created by the USDA to help gardeners determine which plants are best suited for a particular location.

Oregon encompasses 6 hardiness zones. They are zones 4, 5, 6, 7, 8 and 9. Before we get started, determine which zone you live in by visiting this interactive USDA hardiness zone map.

At their core, hardiness zones only represent how cold a particular area gets in winter. This information, combined with the average frost dates for your area, is the key to planting the right herbs and vegetables in Oregon.

Below, we’ll guide you through the best crops to grow in your zone in Oregon and when to plant them.

Spring Gardening in Oregon

Zones 6, 7, 8 and 9

During the spring in Oregon zones 6, 7, 8 and 9, try planting short season produce in March that prefer cold weather, such as green peas, kale, and broccolini.

These crops will feel much more comfortable in the moderate temperatures of spring, as opposed to the intensity of an Oregon summer. And their short growing period means once temperatures begin to rise, they’ll be ready to harvest and replaced with plants more adapt to the Oregon heat.

Classic home garden produce, such as jalapenos, bush beans, banana peppers, and butternut squash are great options for mid-to-late spring planting.

For warm weather crops such as these, start seedlings indoors in March. In April and May, once temperatures at night are consistently above 50 degrees, transplant established plants to the garden.

Zones 4 and 5

In Oregon growing zones 4 and 5, spring is considerably cold compared to most other areas. As a result, the viable growing season in these locations is fairly short.

To get the most out of your garden in Oregon zones 4 and 5, seedlings should to be started indoors. We also recommend using a blanket of straw to help protect transplants from a surprise frost.

With so much of the growing season experiencing cooler temperatures, focusing on frost tolerant crops is a great strategy for success. Vegetables such as romaine lettuce, beets, broccoli, and collard greens can usually be planted in late April or May for zones 4 and 5. Cool weather crops that have a bit longer growing period, such as Brussels sprouts, parsnips, and artichokes, are another great option for the colder areas of Oregon.

But at the end of the day, for most common garden vegetables in Oregon zones 4 and 5, planting will have to wait until things warm up in June.

Fall Gardening in Oregon

Zones 6, 7, 8 and 9

Want to keep gardening in Oregon zones 6, 7, 8 and 9 even as the weather cools? You might be surprised by your options!

Fall crops for Oregon zones 6, 7, 8 and 9 are typically planted around July and August. This should give the plant enough time to establish itself before cold weather begins to set in. Think cold-loving crops such as onions, carrots, and kale. Hardy root vegetables and durable leafy greens are great options, especially if you’re looking for something to plant in September or early October.

Zones 4 and 5

For Oregon growing zones 4 and 5, fall gardening is a race against the cold. Likely, you’ll want to plant short season fall crops during July or August, to ensure ample harvest time before the season’s first frost hits.

Cold hardy produce are the most viable fall crops for Oregon growing zones 4 and 5. Some of our favorites for Oregon are collard greens, iceberg lettuce, beets, and romaine lettuce. Not only can these type of plants withstand a bit of cold, but they’ll be great roasted or thrown in soups and stews during the Oregon winter months.

You can also extend the life of your fall garden in Oregon zones 4 and 5 by using methods such as hotbeds, covering plants with a plastic sheet at night, or “overwintering” perennials such as tomatoes and peppers.

About Me

Hi, I’m Allison! Over the years, I’ve gained a lot of knowledge about growing your own food at home. Now, I want to share that knowledge with others. When I first started gardening, I was overwhelmed by the amount of information available on the subject. It was intimidating! But after years of trial and error, I learned that growing produce at home need not be as technical and complicated as some make it out to be.
