Bill: No, fish oil is not among the offending residues; mancozeb is probably the worst I have. So you think an electric 2000psi, 1.4gpm rig, with a nearby fast hot water heater would do the job? Or maybe even with cold water? I like your suggestion on use of spray oil. It might work as we

A $150 washer from Home Depot works for me. I use hot water from a building that has a water heater. Hot water makes a lot of difference. But now if you're using fish oil everything changes, that stuff is harder to get off than most paint. What I finally figured out to do with fish oil was to pai

It used to be said exterior paint had harmful chemicals that could harm your tree, but EPA is so strict now that it's no worry: use whatever is in the garage. Kevin Hauser n Tue, 6 Mar 2012 12:01:17 -0800, "Tommie van de Kamp" wrote: > Just to clarify, is it best to use diluted interior or exter

Well the good news is that we're gloriously free from Dogwood borer and round-headed borer. But per union contract we have the Pacific Flathead borer. The main ingredient for the drywall mud is gypsum, but may act as you specified. It's cheap and available everywhere, and much more effective tha

Northern Tool and Equipment lists pressure washers from under $200 to several thousand dollars. Would anyone care to advise on needed pressure, gallons per minute, and hot versus cold water, or other considerations in choosing a system to clean exterior surfaces on air- blast sprayer and t

Interesting observation, would be great to see some University trials. Perhaps the silica acts as irritant? Do you still see borers laying eggs and larva not surviving? Also, which borers are targets? I understand that there is work with pheromone confusion a la peach tee borer research going o

I've been using 1/3 paint, 1/3 water, 1/3 all-purpose drywall joint compound; this is still thin enough to brush on, but makes a pretty good crust. I had "Gripper" white primer left over (Home Depot) and have been using it, despite dire warnings about not using exterior paint. If it works again t

Add a slug of drywall mud to the mixture and you'll have borers covered too! This is John Bunker's recipe at Fedco Trees in Maine and was effective last year in reducing borer damage here. Kevn Hauser Kuffel Creek Apple Nursery Riverside, California On Tue, 6 Mar 2012 03:48:36 -0600, Nick Luckin

Randy, I've noticed on mature trees where I had yellow belly sapsucker (woodpecker) damage and I've painted them, the birds do not return to peck. I had quite a bit of vole damage last year where I had painted trunks but no guards. I have started to add hot pepper sauce to the latex pai
