Let's talk Maryland weather. The last two years notwithstanding, our winters tend to be fairly mild. That's the upside. On the downside, our summers are brutally hot and humid with a great deal of rain from mid-May to late June. The grass is green as green can be, and gardens thrive. But then, the waterworks stop. From July through mid-September, Maryland enters a dry season. And that's when things get dicey.
