I really like those in-between times of the year, when spring blossoms into summer, summer fades away into fall, when fall hardens into winter (just kidding on that last one). Seasonality is more tangible; you feel on the cusp of something new, even though you’ve experienced it every year of life so far. Perhaps it’s because my birthday falls during one of those times, but I also like that these passages are rooted in natural phenomena: the shortest day of the year, the longest, and those with equal proportions of day and night. Our cultural ideas of the seasons don’t always match up – we embraced summer weeks ago, pulled out our white linen and headed down the shore, but summer officially begins on Monday, June 21st (at 11:28 am to be precise, if you’re hanging out in Greenwich, England). And I’m always amazed (and thankful) that on the first day of winter (winter solstice, the shortest day of the year), the days actually begin to get longer. Winter’s just begun, but the sun is returning. The flip side, however, is that summer solstice signifies the days getting shorter.
Not to get too scientific or biodynamic-sounding on you (because I’m not qualified in either realm), but this seems fitting in the orchard. Spring is the time of new growth: flowering, fruit set, shoot extension. As the days get longer, the branches also elongate (about 12 to 18 inches, for example, in healthy, productive apple trees each year). Spring is now past; vegetative growth has slowed or stopped, and fruit is enlarging and ripening. As the days shorten once again, the accumulation of all that rampant sunshine, transformed by photosynthesis into carbohydrates, is expressed in the fruit. And in the garden at large, planting is almost over; we’re buckling down to reap the harvest for the next several months. The natural cycle – of growth, fruiting, harvest, storage – is of course in line with the seasons.
You’ve probably seen pictures of the bloom at North Star, and you’ve tasted the results of the harvest, but what’s going on in the orchard in that in-between time, before spring gives way to summer and that glorious six months of the year when there’s fruit to harvest? What have we been up to? Certainly not sitting around twiddling our thumbs and watching the fruit ripen on the trees. Spring is a very busy time of year in an orchard, especially in a young orchard like the three-year old orchard in Cochranville.

Thinned Gold Rush
So we come in, armed with red clippers if it’s Asian pears, or just fingers if it’s peaches or plums. We remove a lot of fruit, leaving just one every four or six or eight or twelve inches, depending on the variety of tree. As we thin, we’re also selecting for the biggest, nicest, undamaged fruits with the best position on the branch. Catch the Asian pear thinning action on YouTube. Every spring the crew spends weeks and weeks working their way through the orchard, branch by branch, tree by tree.
Spreading, one of the main strategies in tree training, is crucial for the development of young orchard trees. Training and pruning are the two main tools we have for shaping fruit trees, to guide them into the desired form and structure. Well-trained trees will need less corrective pruning later on and will develop a stronger, more fruitful framework, even producing fruit at a younger age. The goal of branch spreading is to “set” the branches at an ideal angle. Branches that grow very upright are vegetative, produce less fruit, and have weak angles. In other words, they form a sharper angle relative to the trunk of the tree, which is more likely to break under the weight of developing fruit. Branches with wider angles (30 to 60 degrees from the trunk is ideal, depending on which tree you’re talking about) are desirable because they will produce more fruit and are stronger, less likely to break. Without getting too technical, this works because there is an inverse relationship between vegetative growth and fruiting growth in trees. The more vegetative growth (i.e. leaves and branches) the tree puts its energy into, the less fruit it produces. Inside the tree, this is all controlled by hormones with fun names like auxins and gibberellins. By simply manipulating the position of a branch (up or down) you can manipulate the expression of these hormones. Pull a branch down, and it will produce more fruit sooner.

Tied plum tree
So, during that window in spring when the tree is actively growing and the branches are more pliable, we head into the orchard to do what I’ve affectionately referred to as “torturing baby trees.” The angles of very small branches can be affected by tools as small as a toothpick or clothespin. Larger branches are spread with metal spreaders of various lengths with pointy ends. One end sticks into the trunk and the other holds the branch in place at the desired angle. Another more drastic, and effective, approach is to tie branches down. A clip is inserted into the ground that holds a loop of string. Another string is then attached that connects the loop to the branch in question, holding it in place. Some of the trees (plums especially are notoriously vigorous) wind up with so many strings that it looks like some kind of Maypole celebration is happening in the orchard. By the end of the season’s growth, the tree’s new woody tissue will have hardened, and the angle we’ve chosen will become permanent.
I wish I could say that we were done thinning and spreading for the season, just in time to celebrate the solstice. But on a farm, there’s always more to be done, and, inevitably, it should have been done yesterday. I wish we were ready to simply revel in the ripe fruit coming off the trees (the first plums were harvested on Friday!), but there are more apple and peach trees to spread, more peaches and pears to be thinned. I suppose it’s also fitting that on the longest days of the year, there’s the most to be done.
