When we have warm rainy days like today during the winter, people go around saying "if it was colder outside and this was snow, we'd really have a mess on our hands". I checked a few web sites and it looks like opinions vary, but an inch of rain converts to about 6.5 - 10 inches of snow.
I am not much for this kind of speculation. When it is rain, it's not snow, and we can be thankful for that. I prefer rain to snow, except on Christmas day and maybe Christmas eve. And even on those days I prefer just enough snow for a white Christmas, but no snow on the roads, please.
Right now, oddly enough, we have a thunderstorm rolling through. And more rain. The rain is not unusual in December, but the thunder is.
Actually, snow and consistent cold would be better overall for the garden. Cold, then warm, then cold, then warm temperatures tend to cause a lot of intermittent freezing and thawing, and thus ground shifting, which can uproot perennials and other shallow rooted plants.
But every place has its challenges when it comes to gardening. We just learn to accept the challenges where we are and figure out over time how to overcome them.
Then we become somewhat "snobbish" and insist we would rather garden in no other place than right where we are. (Wouldn't that be quite an exchange amongst gardeners... who is gardening in the best place and why?)
I can't imagine gardening some place else other than where I'm at. It's all I know.
Except, I would convert Indianapolis to one hardiness zone warmer, to zone 6. This would give me some additional plants to work with. Not that I am bored with the plants available to zone 5 gardeners. It's just that sometimes when I'm looking through catalogs, everything is hardy just to zone 6 and thus just out of my reach.
