What is the most difficult pest you deal with in your garden?

slugs. beer is sort of keeping them at bay, but I might have to try that copper tubing trick mentioned by nukeday around my purple beans. they are stunting their growth.

I also have a mystery diner...and by diner I mean something has figured out a way around my chicken wire fence and ate all of my spinach...I protected my kale and it got wiped out today, my swiss chard has been munched on, and my parsley must have been dessert. The parsley wasn't touched when it was in the front yard. And the kale was left alone for a good 2 weeks. :\

did some further investigation on what could be feasting on my greens...chipmunks. my nemesis this season. they are way too clever. they found a weak spot in my chicken wire, tunneled under it and wedged themselves up between the chicken wire and the raisedbed boards. I have added yet more staples to the chicken wire and hopefully this will be the end of their meals. they should be full at this point anyway, little gluttons.

I have also noticed a bit of powdery mildew/mold cropping up on my squash plants. I had this problem last year and didn't get it under control fast enough. Spraying milk does seem to work.
