Hi, I think my plants are getting what people refer to as powdery mildew.. I removed the affected leaves (which are at the bottom). What is the best thing against it, if anything? I'm growing outdoor in Holland and it's kind of wet here, so I guess the problem can reappaer.. any suggestions?

Greetings from across the pond!!
I think you are going to have a problem controlling this because you are growing outdoor in a cool rainy coastal climate. You may want to give indoor growing a shot.
Anyway... my Grower's bible says spraying the plants with a mixture of baking soda and water should raise the PH of the leaf to 7 and powdery mildew can't grow. It doesn't specifically say if this works for outdoor plants. It also doesn't give any specific measures or ratios of baking soda to water..... maybe someone here knows what it should be.
Other then that I'd hit a nursery in your region and ask them what sprays they have that are safe for edible plants that will reduce the mildew on plants in your garden.
Wish I had more then that to offer.
Good luck
