Non-native Black Walnut used to promote growth of native Oregon Oak

There’s a lot of debate about native vs non-native plantings, so I wanted to share that in my opinion they are not exclusive.

For my verges I have encouraged Black Walnut, despite its juglone content, as a pioneer shade producing planting to help other plants get established.

It is particularly helpful in areas I do not irrigate, and I tend to cut it back each winter to keep it manageable.
