📢 : Emerald ash borer has been detected in Washington State near Vancouver. This highly invasive and destructive pest kills up to 99% of ash trees. So far, this pest has not been eradicated in any area where it has been discovered.

Washington has prepared for the arrival of this pest by creating resources for government organizations and individuals. Check out our press release to learn more about this pest and get resources on what you can do now to prepare. https://agr.wa.gov/about-wsda/news-and-media-relations/news-releases?article=47256

Late summer is a great time to check in on your garden and enjoy the results of your hard work.

🌿 Harvest vegetables and herbs regularly
Keep picking what’s ready to help plants continue producing.

💧 Water deeply during dry stretches
Containers, raised beds, and newer plantings may still need extra attention.

🌸 Prune spent blooms
Deadhead flowers selectively to tidy plants and encourage more blooms where appropriate.

🥬 Check the planting calendar
Before starting fall crops, review the WSU planting calendar for crop timing and local microclimate considerations.

🪴 Sit back and enjoy your garden
Take a moment to appreciate what you’ve grown this season!

Did you know there were palm trees and crocodiles as far north as Alaska?!

“The Paleocene-Eocene Thermal Maximum (PETM) at 56 million years before present is arguably the best ancient analog of modern climate change. The PETM involved more than 5oC of warming in 15-20 thousand years (actually a little slower than rates of warming over the last 50 years), fueled by the input of more than 2000 gigatons (a gigaton is a billion tons!) of carbon into the atmosphere. The PETM was associated with the largest deep-sea mass extinction event in the last 93 million years and remarkable diversification of life in the surface ocean and on land.” (Penn State College of Earth and Mineral Sciences)

What can the past teach us about our own changing climate?
How can we gardeners adapt, and ensure our precious PNW biodiversity?

Join us on Sunday, September 13, at Bellevue Botanical Garden for our annual plant sale and class offerings. You'll find a variety of vendors with great plants to choose from plus three topics of great interest. Sign up for all three and you'll have early access to the sale at 9:30 a.m. All the information plus registration is here:
