When do I plant roses in Oregon?
If you’re in western Oregon you’ll want to plant roses from mid-February through early March.
In central and eastern Oregon, because it’s colder than the western side of the state, it’s best to wait until the ground is completely thawed. That would likely be around late April and into May.
Regardless you reside on the eastern side or the western side of the mountains, the process of planting roses is the same. The hole should be generous in size and depth. If you’re planting container-grown roses the hole should be twice as wide as the pot. For bare-root roses, the hole can be 1.5 times the width of the root.
If you’re resident in a milder part of Oregon plant your roses so the graft line appears just above the level of the soil. If you live in a colder region, bury the rose graft around 2 inches below the surface of the soil. Ensure the soil is level around the root graft/ rose stem, not the same shape as a volcano.
