As it stands, blueberries actually thrive in the western part of Oregon, and moderately well in other state regions. Aside from checking the climate and hardiness zone in your location you’ll want to learn about their soil and sun requirements, among others.

Ideally, Oregon blueberries should be planted early October (fall) in Willamette Valley and in spring for other regions. Once you get them settled they’re fantastic growers and can live up to 50 years or more.

Choose a site that gets plenty of sun- the more sunlight they get the better. It’s worth noting that they can still grow in the shade; however, they won’t likely reach maximum potential and may bear less fruit or none at all. Once this requirement is met, you’ll want to have a well-drained soil for the roots to thrive. Blueberry roots don’t need to be that deep and might die if you put the plants too deep.

Another important thing to note is the soil acidity. Blueberries require a soil pH of somewhere between 4.5 to 5.5 in order to really thrive. Thankfully, you can grow them in big containers if the ground soil is not conducive, or add ground limestone to raise it up to the preferred level.

Alternatively, you can plant blueberries in raised beds so you can put in the best soil mixture right from the start.
