The Rural Voice, 1999-07, Page 29trees to mature. Using two-year-old hazelnut trees a grower can get a first minimal crop in three or four years. At first they sold their nuts, then they began using them in their bird -feed business. The problem with marketing the nuts was the uncertainty of the crop. Paul says. "We'd have a good year then we'd have a poor year because it was too cold and we were losing all the pollen." production from hazelnut trees in summer can be determined by severe weather conditions the previous winter. At minus 30 the catkins that will produce the pollen the next spring. start to be damaged. At minus 35, all pollen for the next year will be lost. No pollen, no nuts. The Bennetts had been experimenting with fertilizing the trees with potassium. Though the level of potassium in their soil was high, the trees weren't taking it up, an analysis of the leaves showed. Trees that don't take in enough potassium before winter are more susceptible to the male flower freezing. Those experiments were showing some success, when the blight hit. "It was one of those frustrating things. We were just getting one problem licked when we got another one." In the summer of 1997 about 20 trees in the grove died. Looking at them, Bennett could see lesions but he didn't know at that time it was a symptom of blight. The problem with being a lone wolf in a new industry is that you're on your own if something goes wrong, Paul Bennett says. When he saw the effects on the trees he thought it was filbert blight but getting it confirmed was another matter. He finally dug up an entire tree and sent it to Guelph for analysis and the report came back the lab couldn't detect the blight — yet the trees kept dying from blight -like symptoms. Last spring he called in OMAFRA advisors who initially confirmed his fears that he had blight but couldn't be certain. "We know that's what it is and we're just stopped wasting our money," he says. It takes 14-16 months from the time the tree is infected before it 26 THE RURAL VOICE shows any signs of damage and more time again before the tree dies. Last summer about 20 per cent of the grove died. This year, indications are that 60 per cent of the grove is dead. But when an aerial photographer came to the door selling pictures of the farm last year Bennett noticed something. Two of the rows of trees seemed distinctly fuller and greener Paul Bennett shows some of his bird seed products while happy customers enjoy them in the background. than the rest of the grove. "I thought there's some hope here that maybe we have something — because if we have a survivor, even one tree that has decent nuts and an immunity to this disease it could be worth more than the whole grove. It could be the Macintosh apple of hazelnuts. I'm trying to look for a silver lining to this black cloud," he says. In the meantime the trees have been left to fend for themselves to see if there is a fittest to survive. Besides, it's depressing seeing all the years of work and hope in such a sorry state. The Bennetts have experimented with other types of nut trees over the years. Korean pine nuts are being grown with success by one Niagara grower, Bennett says. The trees are very hardy but they require a mycrrhiza in the soil to grow. The correct soil conditions can be initiated by surrounding the plants with pine needles but unless the tree creates enough needle drop of its own, the grower has to keep providing pine needles to supply the mould required. After a while Bennett gave up trying to supply enough pine mulch and the trees have slowed their growth. Even in a cultivated environment, Korean pine nuts probably take 15- 20 years to produce their first nuts and in nature, 60 years. Their experimental group of Korean pine nut trees are now 10 years old — and only knee high. Other experiments have involved heart nut, almond, pecans and carpathian walnut (the traditional eating walnut). "For the most part each of the trees is still growing but with limited success." Each variety seems to have a weakness that makes it unsuccessful in Bruce County climate. The heartnut, for instance, is susceptible to late spring frosts. If he had planted the trees on the hillside at the back of the farm they would likely have done better, he feels. Similarly, the carpathian walnuts planted on that hillside have been much more successful than the trees planted on lower fields. They have surviving pecans but the Bruce County summer it just too short for them to produce mature nuts. Almonds find the climate too cold at the elevation of the farm, though down by the Lakeshore they might do better, he says. Still, even as he walks through his devastated nut grove, Bennett has high hopes for nut growing in Ontario. Each tree can produce 10 pounds of nuts that sell for $1-$4 a pound. With 200 trees per acre that's an income of $2,000 to $8,000 per acre, he says. "It was worth the experiment," he says. There's a potential to expand the market for nuts with a locally grown nut, he says. Ontario residents don't know what a good nut tastes like. Most of the nuts imported to Ontario are several years old, often the nuts that countries with discriminating taste refuse to eat. Fresh nuts are sweeter, with no bitterness like the nuts normally sold here at Christmas. Though the investment of time, energy and money in planting the 20 acre grove seems to have been lost, it 1 1 1
