…the koi have been up and about all fall, not going to sleep yet. They’re uncommonly nervy: I wonder if they don’t perceive our near water level lines as some sort of protection. They’ve never been so out and about. But that’s about to change: Wednesday will be in the 50’s. Wednesday night a cold air mass arrives, with moisture, and snow and freezing rain are possible, not to mention fog.

Our new trees and bushes are being quite pretty: the magnolia and birch and weeping cherry have gone bright yellow, the hawthorne is gold, the new cherry tree (sakura) is bronze with hints of red. the dogwood is reddening, our red Japanese maples are brilliant, and the burning bushes are raspberry red to brighter red, and the Virginia creeper is going red along the front stonework. We are very happy with our fall color: we didn’t know how they’d all go in fall, but the placement and look is very nice.

We lost one of our Japanese maples, the green one, to verticillum wilt, which is a soil fungus very common up here: most Japanese maples sold in the PNW have the problem, according to one horticultural site. And there’s no cure for it but to plant something that ignores it, like an apple, or such. Except—cauliflower growers in California also fight this pest, and one discovered—wait for it—that it hates broccoli. Apparently broccoli has something in it that verticillum can’t abide; and they chop up broccoli and use it as a soil treatment.

Well…so we got a lot of broccoli from Costco and chopped it up, and dug it in around all our Japanese maples, for starters. We also dug it into the place where we had to take the green maple out. Next spring we are going to plant a new green Japanese maple with a lot of broccoli, and if it lives and thrives there in soil we know was infected, we’ll go on broccolizing our trees.
