Your garden must smell like heaven! :D: No one can truly know what you mean about minty fresh unless they've smelled that stuff.

I have used grapefruit seed extract to control mildew on the beams/rafters in my basement. It seems to work well, and the extract is a dietary supplement, so there shouldn't be any danger in that respect. I have never tried it on plants, so some testing is indicated.

I have used neem in my greenhouse on lots of plants. Mainly for insect control.

The only problem i have had is on cabbage,broccoli. Their leaves will not tolerate it.

If you use it, make sure not to apply it in the hot part of the day.

I have not had any problems in the greenhouse with Powdery mildew , so i dont know how effective it is once it has shown up.

oooohhh yeah.... neem works great for powdery mildew. I think I mix something like 25 ml to a spray bottle (somewhere around 500 - 600 ml).

Yes, neems oil works great on powdery mildew on squash, and knocks down most fungus on tomatoes and our berry bushes.
