A couple of news have been just released that make a nice overview of the truffle farming industry in Chile and USA. I thought it could be nice to share it here:
Why Haven’t American Truffles Taken Root Yet?
and the Chilean one, where they describe the truffle industry in Chile for the last 10 years. Though it is in spanish language, but worth try the translator:
«Una década del cultivo en Chile: la trufa comienzaa oler bien»
BTW, I´ll be in California again from 23rd august to 5th september 2017, just in case any local grower need anything…
Cheers,

Hi Marcos, that story on US truffles is a real cop out. It’s a new industry in the States only because growers haven’t been successful. There was a concerted effort to grow T. mel. at Dripping Springs, Texas in the early ’90s and every new attempt to grow T. mel or borchii is seen as new and novel. Giving advice to the yanks on growing truffles has to be a goldmine for you.
Peter, with all due respect, your comments to Marcos were mean-spirited and not entirely accurate. Some growers in the U.S. have produced truffles, and those who haven’t should readily understand why they have not been successful. A ‘concerted effort’ tells us very little about what actually took place in Dripping Springs. Many (read: most) orchards I have visited are poorly managed, and often neglected. Many growers are not following recommendations or they are getting bad advice. Compacted, heavy soil, poor drainage, poor choice of host trees, not using Spanish Wells, etc. EFB has been around for many years, and is (was) well documented. Yet growers planted C. avellana anyway, or planted Q. ilex where it isn’t cold hardy. What did they expect? Growers must do their homework. One cannot simply plant trees, and walk away, to return several years later to harvest.
filbert blight is affecting lots of plantations in the States. Now changing host trees. I´ve seen now pretty nice young orchards with high potential if well managed. I love their spirit that “I´ll make it happen” 🙂
