I think I have mentioned this already but back on to these Mildew and Bud Rot issues. I have been trying to find a something, anything, between "the when" the Powdery Mildew appears on the Cannabis plants and on other plants in the immediate area (my backyard). I am sure that the mildews that show up on squashes, cucumbers, oak trees, Bindweed (Morning Glory) and the other plants are different strains than what we have to watch out for.Y’know, now that you say that.. My MIL has fought PM every year she’s grown. This year my FIL decided to grow. However, because of scheduling/timing he wound up getting the plants out a month later than normal, and he currently has zero PM going on.
It’s gotta drive my MIL nuts the two of them are pretty petty and emotionally childish so they weirdly compete out of anger or jealousy. My MIL was convinced my FIL was gonna fail because he started so late and doesn’t know what he’s doing. He just grew them like the rest of his veggie garden. He has produced much higher quality plants that are much more healthy
Now there might be a correlation. I believe that the mildew on my Zinnias is the same variety of Powdery Mildew as what shows up on the weed plants. The first signs of mildew on either of them is the same. To stop planting Zinnias is not the answer since the spores are blowing on the winds so they will attack the Weed even if the Zinnias are gone. Maybe it would be better to plant more Zinnias to trap the mildew spores before the wind pushes them into the stealth areas. Won't trap them all but if it reduces the amounts still on the wind it is a good thing. Plus the Zinnia flowers attract pollinators, mostly Monarch butterflies and bees
I noticed a blackish area on the mint flower stalks and it immediately reminded me of Cannabis Bud Rot. Going to add that to the things to look for next year in the late summer.
