English Ivy growth in shade vs full sun
Is there scientific research indicating that English Ivy will grow back more quickly from a plot it's been removed from if the plot is exposed to full sun, whereas more slowly in more shade? The location is in Portland.
Multnomah County Oregon
Thank you for your question. I have attempted to find research implicating sunlight as a factor in growth patterns with this plant. My review suggests that it is not as light-sensitive as many other species. https://extension.oregonstate.edu/news/english-ivy-invasive-weed-pacific-northwest https://extension.oregonstate.edu/news/english-ivy-can-be-contained But you are able to research further using search terms of ‘light sensitive english ivy site:edu’ Good luck!
