lee reich’s blueberry-growing how-to
DON’T SAY ‘I CAN’T GROW BLUEBERRIES,’ says Lee Reich, whose PhD explored factors affecting the growth of Vaccinium corymbosum, the highbush blueberry. “Follow the prescription and you can.” So what exactly is Lee’s Rx? It’s covered in his latest book, “Grow Fruit Naturally,” along with detailed how-to on every imaginable home fruit crop (in pots or the ground) from kiwi to pawpaw, citrus to pomegranate to plain old strawberries, apples and pears, 31 kinds in all. You can get his blueberry tips below—and I’ll even let you know what’s going on in the photo up top.
Lee Reich and I have been writing about gardening for a similarly long time, connecting off and on throughout our careers. The last time I saw him? Saturday, during my Garden Conservancy Open Day, when he just walked up the driveway, quite to my surprise. His books “A Northeast Gardener’s Year” and “Uncommon Fruits Worthy of Attention,” both published around 20 years ago, are longtime favorites of mine, and the newest, “Grow Fruit Naturally,” has Lee’s characteristic fusion of solid science; practical, nature-inspired common sense, and a consistently considerate relationship with the environment.
TO BE PROLIFIC fruit producers, blueberries do have special soil requirements, Lee acknowledges, but he manages to provide that and get more than 180 quarts of fruit each year from 16 highbush types in his home garden (which he calls a “farmden,” as in half farm, half garden) in New Paltz, New York, across the Hudson from where I garden.
Me? I grow lowbush (Vaccinium angustifolium) and highbush types, both Eastern native species, for their spring flowers, red fall foliage (below) and the fact that they are favorites of birds (and unfortunately my local army of chipmunks). I never eat a single berry.
Identify a sunny spot, and then adjust accordingly to also provide very acidic soil that is well-drained but moist, infertile (“Yes, you read that right,” writes Lee) and high in organic matter. If drainage is a problem, consider raised-bed planting.
Start with a soil test (blueberries like the pH in the 4-5 range).
If the pH needs adjustment, use sulfur to acidify the soil. (Pelleted is cheaper and easier to apply than powdered, he says, but either one used according to what your test indicates.) Add the sulfur to the soil of the planting hole, and also spread it around the area that will be the eventual root zone of the plant as it grows.
Lee mixes in a bucketful of peat moss to amend each hole at planting time. Because peat is a non-renewable resource and under intense scrutiny from environmentalists, who advise against its use, I asked what else we might try.
“What’s needed is some long-lasting form of organic matter that isn’t rich in nutrients,” he explained. “Thoroughly rotted sawdust is another possibility. Probably very old compost would be O.K. too because much of it would be stabilized organic matter that would release nutrients only very slowly. Back to the peat moss, though; this is only a one-time application.”
After planting, water well (a practice that will need to be kept up particularly in the plant’s first few years in the ground; Lee’s blueberry garden is on drip irrigation). Mulch to a depth of about 3 inches with wood shavings and chips, pine needles, autumn leaves or sawdust.
Lee replenishes the mulch each fall, after leaf drop—and also feeds the plants at that time with soybean meal at the rate of 1 pound per 100 square feet. He retests the soil pH every few years, and adjusts with more sulfur as indicated.
Starting at four years old, the strict dormant pruning regimen begins on highbush plants, because stems aged six years or older are not good fruit producers. In late winter, the oldest stems (they will be about an inch thick) are cut out to the base (photo above shows how the base of a mature plant looks after pruning, with a good mix of older, younger, and middle-aged stems remaining).
After more than 20 years of following these practices, Lee’s bushes are still prolific—and as I said, he even gets to eat the fruit. That’s because of the last step in his Rx: the blueberry gazebo (top photo, seen in winter).
What a coop is to predator-prone chickens, the gazebo—netted top and sides—is to blueberries. A delicious solution.
Just before he left my garden, Lee had a question for me: “So what will you do with that potted fig on the patio this winter, Margaret?” I’ll put it in the unheated garage with the Japanese maples, I replied about the plant I just bought this spring. Oops! No, says Lee, the fruit doctor. Guess the next chapter in “Grow Fruit Naturally” I’ll be reading is the one about figs–or read this later interview about successful fig growing with Lee.
