Hmm... I have a squash plant that is just covered with powdery mildew (happens every year). I am debating between the aspirin (somehow seems wrong to be spraying that in a veggie garden) and trying the baking soda spray. (Too bad that I was just at the hardware/garden center last night - could have gotten yet another spray bottle.)
For what it's worth, I just picked up the last two 'Angel Daisy' plants from the nursery today (rather one of three nurseries I regularly surf, not including the hardware garden center). I thought that they had the white Echinacea there too, but noooooo, that's at one of my other haunts. SIgh. (Some days it's hard to remember which plant I got from where.)
I also picked up a large flowering white dahlia, 'Kiev'. (This is a dinnerplate which is supposedly white and pink (per Google), but the flowers on my plant look pure white to me. I am presuming that the nursery label is correct (but I have seen mislabeled dahlias at nurseries before).) That will make 3 different white dahlias for the Moon Garden now ('Prince Charming' (cactus), 'Eveline' (decorativel with a bit of lavender in the center) and now 'Kiev' (very large very white).
Those will have to be planted next weekend. Today we played around with the irrigation heads, so that we could plant out the two 'Flower Carpet White' roses.
