Farming is beguiling. For the most part, it hinges upon showing up and giving it your all. Some is applying knowledge. Within that framework comes a term, partly scientific in bent, that applies the principal of hypothesis to the quotidian. Delve the depths of literature devoted to site planning of a fruit orchard and you will run across many a dialogue that deals with late frosts / freezes. Invariably, they point to a maxim that stipulates an orchard on a slope has the greatest chance of cheating the deep spring plunges of temperature.
Physics, or its sibling Chemistry, prove that a volume of gas tends to seek lower altitudes as it cools. Our atmosphere is no different. The slope principal interprets that tendency into an understanding that hillside orchards have a flow of atmosphere, wherein, as the air at orchard level cools, it travels down the hill. This movement of air mass draws in warmer air from the next layer just above into its place. To work perfectly, an orchard must be positioned such that it is not at the peak of a promontory, as well as having a clearing below it to accept the sliding air mass.
When we set about looking for land to start an orchard, we had this concept on our minds. It was one of many considerations that went into the calculus of which properties to make an offer on. Sure, it is a ton easier, and other more graphic terms, to propagate, manage, and bring an orchard to fruition if its entirety is on a completely flat plane. Then the 50 year frost hits. Or, even the decade frost. Both will bite deep into your crop.
By all accounts, this one was a doozy. Stone fruit grown in New England will be equivalent to hen's teeth this year. Almost without regard, apple operations will struggle to pay for inputs, given the damage done. We, once again as a result of being unconventional, have managed to emerge unaffected by the May 28th super freeze.
Our orchard is not flat. At the very least, you can count on a 7% incline no matter where you stand in it. At points, it approaches a 15% incline. The lower end bounds a clearing that is at least 15% grade. This all translates into a concept that as air cools in the orchard it should slide down hill, as it has a place to flow.
On April 22nd, we transplanted 56 trees to finally fill in the un-propegated corners and replace some dead loss. As usual, they kept us biting nails as leaf out dallied well behind the established. Finally, about May 22nd, they all showed signs of bud break. Just days later, the 50 year frost hit. Through the grape vine, we heard of operations with new transplanting losing all of them. That, in addition to taking it hard in fruit set. The hill had a different experience. None of our transplants experienced any setback from the sub freezing event that had neighbors thermometer's registering 28F for hours on end.
Farming is beguiling. Not the least of which experienced by a farm on a decent incline. When we plant new trees, it takes a effort above to create berms that keep water around the newly transplanted ball of roots. Then there is the logistics of hauling water to keep them hydrated. Once producing, it is no small task to keep a tree fed and protected from insects, viruses, fungus and bacteria; all a result of applying inputs that arrive at a much lower elevation.
Overall, the orchard spans just over a hundred feet in elevation. That is after taking a two hundred foot climb from where the tractor is stored along with inputs. Overall, this daily hurdle saved us from the 50 year frost. Hopefully, we will not have to test the proof of concept in the 1000 year freeze. Things are challenging enough.
Final note, the fruitlets pictured are Wolf River. Get your pie tins ready New Hampshire, because this orchard will have plenty of apples for your pies this fall!
