The Beginning

I have been posting a bunch of hap hazard stuff on this blog and have recently realized I have missed a great opportunity to explain what is the whole hub-bub about with this truffle thing. To start with I am not talking about chocolate, I am talking about a fungi. A very special and tasty fungi, much like a mushroom bur grown underground. (Those of you wondering, the chocolate truffles you might have eaten during Valentine's Day are named after the fungi because of the way they look.)

This ungrounded fungi that is unlike any other mushroom you might have seen, smelled or eaten is called a truffle. There are thousands of truffles in the world and just like mushrooms, some you can eat and some you can not. Some rare. and highly desired truffles (Italian White) and have such a unique taste that their prices are North of $3000/lb. One rare large Italian white truffle sold at auction for $200,000! See article.

You may read this and be wondering, are they really with all that? That is a difficult question to answer as we asked ourselves the same thing. Then we had a dinner where Period Black Truffles were served throughout the meal as a dressing, salad topping, sauce and mixed in with a risotto. That answered our question with a hell yes they are worth it!

So what are these little gems? The first time you see one in real life, you think it is just a clod of dirt or something your puppy might have left in the yard, if you know what I mean. They are the fungi of an ectomycorrhizae that grow on the root of certain trees. Much like the apple to an apple tree the truffle, or in our case the (Tuber Uncinatum), is the fruiting body that grows from the mycorrhizae on the tree root. The ectomycorrhizae is a muchical benefiting relationship between the tree and the fungi. It helps the tree roots to reach nutrients that it normally couldn't and the tree then gives back the nutrients needed by the mycorrhizae. For a more in-depth description, click here or simply do a Google search for ectomycorrhizae. Warning! If you are not into science or biology and attempt to learn more on this subject, you head may just explode. (mine nearly did).

Now that you are back from googleing all of that, you may be asking if so many trees have mycorrhizae, they why don't they all have truffles? Remember that apple tree analogy? It is for the same reason not all trees have fruit or nuts or pine cones on them. Some trees grow a type of truffle that you would never want to find on your dinner plate while others are edible but have no real commercial value. The type of mycorrhizae we are after only grow on a few specific trees and in very strict soil and climate conditions. Those factors are what make these little treasures so rare. They are not like corn that one can grow almost anywhere and in fact you really don't "grow" truffles but you cultivate them like a button mushroom. We provide the tree and fungi everything it needs to grow but it is up to mother nature weather the tree will bear fruit.

So can you just plant some trees and poof have a truffle?  Kind of.  The poof moment does not happen for years, anywhere from as little as 3 years up to10+!  (the avgerage person can expect truffles in years 5-7).  When you plant trees innoculated with the type of Tuber you intend to harvest, it is a risk.  In Iowa the ground is frozen during the time the Black Perigord truffles are ready to be harvested so you may be able to grow them but you would not be able to harvest them and I am pretty sure selling them would be out of the question if you did get them out of the ground. That is why we turned our attention to the tuber uncinatum or Burgundy Truffle.  They are harvested in the fall just before the freeze.  Why is freezing bad?  Take a look at the picture above.  These truffles came from a farm in Norht Carolina, the on the left was harvested after the ground had frozen for only a couple of days.  Even though it is still a "fresh" truffle, meaning it was just pulled out of the ground.  Because it was frozen it can not be sold as a true "fresh" truffle.  North Carolina had an unusually cold winter this year.

What about value, how much are they worth.  That all depends.  Again you can Google any of the above varity of truffles and you will find prices for fresh Italian Whites around $3000/lb, Perigord Blacks around $1600/lb, and Burgundy's for about $500/lb.  These are of corse retail prices on the internet, I do not know for certain but I imagine that restraunts and chefs are paying a little less then retail. 

"How many pounds of truffles can I get out of a tree"? ,you may be asking.  This is a product that yeild is not measured by the tree but by the acre.  One tree by itself would most likely not produce a single truffle.  (In fact to this day, no one has been able to grow truffles on trees grown in containers.)  Truffle orchards are planted in mass, as much as 500 tree/acre in some palces.  I have read that a person could expect a yeild for Black Perigord truffles, around 35lb/acre on a well maintained orchard and at current prices, one can see how lucretative just a few acres could be.


In the end though, this is still an agricultural venture and should be treated as such. Trees must be tended to much like any other crop. This means that you are subject the will of mother nature and must plan on how to deal with all the things she can throw at you such as drought, floods and pests. ( This truffle on the left had it's fair share of visitors before it was pulled from the ground.)

Cultivating Truffles in Iowa

After month of research and discussion with our friend on the East Coast I can finally say I have a plan. Starting with only one acre at a time will enable us to use our existing equipment without having to invest a ton of money into big farm machinery.

This Spring (2010) we will break ground and bust up the grass using our single bottom plow. Next we will have our local co-op come out and apply 2 tons of Ag Lime, after which we will rotor-till our rows we intend to plant. Using the advice from our friends we have come up with a spacing for our trees and rows that will accommodate the growth of mixed oaks and filberts and should ensure rapid distribution of the mycorrhizae. We will follow up the tillage with a total ground kill herbicide and continue to spray the rows throughout the spring or as weeds appear. 

Then it is just spray and till, spray and till until fall.  Fall of 2010 we will get another soil sample and have it tested to ensure our pH is rising.  Hunker down for another winter.  If all goes a planned in the spring 2011 we should be able to start spreading lime (again), till, lay drip irrigation, and plant trees!

My How Time Passes By


Have you ever seen those fun little time-lapse movies where they build an entire house in just a matter of minutes?  Or have you seen the videos of the setting sun with clouds rolling by in a matter of seconds?  Those videos have always amazed me and they got me thinking.  I have never seen a time-laps video of a tree growing.  Mostly because a tree takes so long to grown and unlike me, most people don't care.  So I decided to look into what it would take to create my own time-lapse movie of a tree or trees growing.

The first search results that came back were very discouraging to say the least.  Most places want to sell you a fancy timer to plug into your $1000+ camera or hook up your camera to a laptop for a few hours.  Neither of those solutions fit my need.  All I needed was an inexpensive camera, enclosure and timer that I could leave up outside for a few years.  Not too tall of a request is it?  Anyway, I found the solution, it is call a PlantCam and it is made by Wingscapes and it costs less then $100 and you can find them on eBay or Amazon.  It has some great reviews even thought the picture quality is not considered High Def for this day and age but who cares for this price!

I have place my order for one and expect it to be here within a week or so.  I hope to get this up and record the snow melting this spring.  If all goes well, I will be posting videos by March.  If all goes as planned, I will be able to record our entire truffle planting process from breaking grown, to planting and with some luck, HARVESTING!
