I figure on early July as the last chance to plant warm-season crops like cucumbers, summer squash and bush beans. This is actually a good time to plant parsnips, especially if you pre-sprout the seeds in damp paper towels.

The wet weather pattern is frustrating, but I'll take it over drought anytime.

Planatus, thanks for that suggestion on pre-sprouting the parsnips. I will try that. I have already dug a trench for the parsnips just now, but I will cover it, because it is supposed to rain again. (That trench is just to make the soil for the parsnips nice and friable, so the seed can grow deep and long: I am not going to plant the seed at the bottom, in case you are worried!) And you're right about being grateful for the rain.
