Years ago after visiting Europe we were fascinated by the truffle after having a delicious truffle dish in Italy. Truffles can grow in the USA with a good climate, optimal site choices and proper cultivation procedures, the Black Perigord production will occur under hazel, oak, chestnut, poplar, willow and other trees. To ensure tree health and viability Locust Grove has selected hardy stock primarily in oak and hazelnut, the best potential hosts for truffle production.
TRUFFLE LIFE CYCLE
- Oak has the longevity to sustain truffle production over a century, requires less pruning and produces less debris;
- A truffiere can use mixed species or monoculture – it is an individual choice.
- Hazel has a lifespan of over 40 years and the benefit of the secondary hazelnut harvest but requires extensive pruning to produce a tree form;
The key to successful truffle production to establish the symbiotic relationship between Tuber Melanosporum and its host tree. This association involves the complete envelopment of the tree roots by the fungus. The T. Melanosporum, in return for mineral ions, particularly phosphorus, receives carbohydrates from the tree. In order to promote optimum truffle production constant nurture and protection safeguards this association to ensure the root coverage is complete and undisturbed.
Trials have been ongoing to expand our variety of host trees that accommodate T. Melanosporum. Our primary goal is to ensure the highest quality truffle production while also ensuring climatic suitability, adaptability and consistent production in the widely varying extremes of Canada’s climate.
Locust Grove Truffle Trees
Truffles raise hardy host trees well established in gallon containers. Quantities available in a given year will vary. Recently available proven host tree varieties are:
Oak wood has been valued for wine cask construction, its acorns for a high protein food supply, and now we recognize it as Canada’s leading native tree that produces Black Perigord Truffle. We are delighted that it is proving to be an excellent truffle producer.Documentation of harvest time is ongoing and closely connected to our documented year-round soil, weather and other conditions.
Trials of some other varieties with excellent potential are ongoing. Current trials include:
