In his free time he loves taking photos of Madrones, seeing them mightily growing out of cracks in our concrete jungle.

The Collective

Propagation of Future Madrone Forests
This species in on the decline across its range, so we think it is important to cultivate and plant more of them in locations where they will fare well. One can look for the characteristic red fruits in the late fall and into winter. People soak the seeds in water for a couple days to a couple weeks. Some folks then spread these seeds directly onto bare ground, but we can also whiz the soaked berries in a blender to help separate the small seeds from the fleshy pulp of the berry. Research indicates that we cold stratify the seeds in the refrigerator between 20 and 80 days to mimic nature’s winter dormancy. After the stratification period, we can sow the seeds into flats with a light soil mixture to be transplanted into larger pots sizes later if needed. Many think this species is tricky to transplant and there is some truth to that urban madrone myth. We will address that issue in later editions.

Madrone: PNW Medicinal Plant
Another way to familiarize ourselves with Pacific madrone is to learn about how it has been used traditionally as medicine. The thick, leathery leaves of the tree are astringent, antibacterial and a diuretic, which people can use to heal urinary tract infections, decrease skin inflammation and stanch light bleeding. One can clip the leaves from the branch ends between mid-spring and through mid-fall to be dried and crushed. Adding alcohol to a jar of the crushed leaves can make the medicinal constituents more available when consumed as tincture or added to a standard infusion tea. Collecting and using wild plants can be risky, so please know the detail above is for information and entertainment only, and not intended for self-treatment of medical problems.

TreeSnap Update
WSU Ornamental Plant Pathology is collaborating with USDA Forest Service and City of Seattle Parks and Recreation to conserve and restore Pacific madrone. Help us to collect data on Pacific madrone so that we can get a better understanding of where the sick (and healthy!) trees are. Another important use of TreeSnap is to identify the geographic range of the species and help to answer questions about its movement under climate change. You can see the current observations here: 

Featured Disease – Phytophthora root disease 
Winter in the Pacific Northwest is a cold and wet time. Not great for trees and humans that like the sun, but ideal for Phytophthora. Phytophthora is a microscopic organism whose name means "Plant Destroyer" in Greek. It is very good at what it does, because it has spores that can swim and attack plant roots in wet or flooded soils. Read more about it here:

Upcoming Events!
Madrone Decline and Recovery Workshops
The February 16 workshop at Camp Long in Seattle was a success! More than 20 people came out in the snow and learned about pacific madrone, then tried out the TreeSnap app on trees in the park.
Join the Arbutus ARME on March 23 in Puyallup. The workshop will explore madrone basics, forest ecology, pathogens, conservation efforts and propagation tips. We will also introduce everyone to the TreeSnap app to survey and map madrone anywhere and everywhere.
The outdoor portion will include a visit to one of the madrone common garden sites where we are studying the genetics of this tree.
