Fire-resistant Plants for Home Landscapes by Amy Jo Detweiler & Stephen Fitzgerald

Available as a pdf.  Summary of this 48 page publication: As homeowners continue to build in the wild and urban interface, they must take special precautions to protect their homes. One way to do this is to create a defensible space around the home, and one important factor can be using fire-resistant plants in landscaping. While taking actions to create a defensible space do not ensure that your home will survive a wildfire, they substantially increase the chances. This publication provides a diverse list of plants that are both fire resistant and attractive.

 

 

 

em9103_1Fire-resistant Landscape Plants for the Willamette Valley by Brooke Edmunds, Barb Fick & Paula Lupcho

Available as a mobile app for iOS & Android (eReader plant list also available).  This app is a local supplement to the main publication, Fire-resistant Plants for Home Landscapes (link above).  Summary: The Willamette Valley is known for mild, wet winters, but summer droughts leave the valley as vulnerable to wildfires as drier areas of the state. Homeowners can decrease the potential for damage to their property from a wildfire by using fire resistant plants in landscaping. No plant is fire-proof, but some are considered fire resistant. This publication highlights fire-resistant plants that thrive in Willamette Valley growing conditions. It provides a diverse list of plants by category: groundcovers, perennials, woody shrubs and vines, and trees.

Is there a list of ash tree alternatives? Choose anything but ash (Fraxinus sp.) to avoid loss to Emerald Ash Borers.  Good general source of information: http://www.emeraldashborer.info  Local training from OSU Extension on potential invasive insects affecting trees: http://pestdetector.forestry.oregonstate.edu/programs/registration-and-online-course

What to spray to treat Azalea Lace Bug? http://insect.pnwhandbooks.org/hort/landscape/hosts-and-pests/azalea-rhododendron-azalea-and-rhododendron-lace-bug Robin Rosetta with the OSU Extension Nursery IPM program has indicated that the nymphs are emerging.  This stage in the life cycle is especially vulnerable to contact insecticides (this is different from the systemic insecticide that the questioner mentioned).  Labeled insecticidal soaps and neem-based products may be a good choice.  Good coverage of the underside of leaves will be necessary.

Recent change in USDA Hardiness zones-does that indicate global warming? “Climate changes are usually based on trends in overall average temperatures recorded over 50-100 years. Because the USDA PHZM represents 30-year averages of what are essentially extreme weather events (the coldest temperature of the year), changes in zones are not reliable evidence of whether there has been global warming.”  From: http://planthardiness.ars.usda.gov/PHZMWeb/AboutWhatsNew.aspx
