We are in that "in-between" season right now when it is too early to do much to the garden but the seed orders are in and there is really no reason to go through the catalogues another time, although I got a seed catalogue from a company down in South Carolina a few weeks back that has me thinking disloyal thoughts about our puritanical climate. My wife, more given to action than to words, seized a garden fork and a rake the other weekend and produced a raised bed within minutes. It was obviously the work of one who was tired of waiting for 40 growing degree days (GDD) to arrive with some sort of regularity. If I remember the drill correctly (I forget it after the growing season is over in the Fall and always have to go look it up in the Spring but at the moment I can't find the book that purveys the needed wisdom), you take the high and low for the day, subtract 40 from each and the result is the number of growing-degree days to base 40. Yesterday's high here was 57 and the low was 29. Plus 17 and minus 11 works out to plus six GDD yesterday. Don't ask me what it was in Celsius. (Alternatively, you could add high and low together and subtract 80 to get the same result. Why didn't I think of that before?) |
