My cucumbers tried hard to fight powdery mildew with the help of baking soda, but since the fruit were bitter anyway, I eventually just yanked them out - hence the empty containers on the deck. It turns out that having a vegetable garden isn't all fun and games.
For next year, I am going to try my luck with more root veggies. Since carrots seem to be doing okay, I'll try to grow turnips and radishes. I am tempted to try potatoes as well. I'm also going to add more herbs to the mix: dill, coriander, thyme and lavender. Beans will need a different spot, as do the peas and onions. I'll plant the leafy greens earlier on, and I'll be more prepared to fight the slugs.
All in all, having a veggie garden has been a win-some-lose-some deal. It has been fun, and to some extent, rewarding. I am sad that my tomatoes are dying though. I can only hope that the remaining two plants stay healthy for a little longer.
