Pseudotsuga menziesii: A Complete Guide to Using Douglas‑fir in the Ontario Landscape
Douglas‑fir (Pseudotsuga menziesii) and its hardy cousin, Pseudotsuga menziesii var. glauca, are two of the most underrated evergreen trees for Ontario landscapes.

In this post, we explore where Douglas‑fir performs best in Ontario, the pests and diseases to watch for, and a few fun pieces of trivia—including why this iconic tree isn’t actually a true fir.
