How to encourage blue stain in pine.
« on: September 26, 2014, 11:50:57 AM »
I have a bit of an unusual problem.  I make rustic crates with the lumber I cut on my mill.  By rustic I mean the rougher and worse looking the lumber the better.  The pine that I cut in the summer naturally started growing blue stain.  Now that the weather is cooling it isn't growing anymore and some of my repeat customers are complaining that the crates I am sending them are not rustic enough.  So is there any way to get blue stain to grow in the fall and winter? 

I have thought of soaking the piles with water than completely covering them with black plastic to trap the moisture and collect the heat from the sun. Any other suggestions?

You may also try going to the "wood processing and drying" part of the forum and ask "Genewergart  wood doc" He is very knowledgeable in the stained, mold and fungus fields.

This is interesting. Blue stain occurs naturally in Pines out here that have been standing dead for awhile - such as after a fire. Except for custom work, it is generally undesirable, and therefore there is a huge push to get the dead/dying out of the woods after the fires. I didn't know you could "encourage" it after cutting live wood.

I just looked it up.  It appears as if blue stain has different meanings.  In the Rockies and west it is a fungus that is spread by beatles that prevents the tree from defending itself from the beatles and eventually kills the tree, it ends up with the sapwood turning blue.

Blue stain can also be any type of fungus that grows in the wood after the tree is cut and before the lumber is dry,  it isn't the same as mold or mildew.  Mold or mildew grows on the outside of the lumber, the stain grows inside of it.  It can be caused by many different types of fungus.

The second one is the one I am trying to grow.

You are only going to have blue stain in the sap wood. Do you have a warm garage where you could dead stack your outer boards and keep them moist? Right after the blue stain comes the white mold. That's one step too far. :D

You need heat and humidity for blue stain. The surest way is to cut as much pine as you think you will sell in the hot humid summer months. Before really cold weather you could try dead stacking and cover with black plastic. Frank C.

Without Pine Beatle Pee you are wasting your time.

I have been told by a provincial government foresty guy that there really is no other way to get it. It contains a bacteria/fungus that when exposed to air and moister and warmth it will start to grow.

I would NOT however Recommend growing Pine Beatles.

The black plastic should work.  There is moisture in the wood and the black plastic will trap the heat that you need.  Not sure if it will work after freezing weather, though, as the fungus that causes the stain may not be active.

I still have about 20,000 bdft of pine to cut.  Since it has been sitting around through the summer, I'll be seeing lots of blue stain (caused by heat and humidity around here).  I'd be happy to send you some.   ;D

How about contacting other local sawyers and either working a trade for you "undesirable" perfectly good wood or possibly just buy their logs with blue stain.
I've known guys that did the rustic look on things for people and understand what they are wanting. Another great trick they used was taking a chain with a bunch of bolts run through it and beating the heck out of the boards before building or burning them a bit then cleaning it up halfway and building.

Why would you have all that Pine lay all summer? Did buy it or just cut it off your land?

I buy pine from loggers who only supply it during the months between November and February.  Since I sell lumber I have to guess how much I might need.  At the time it looked like milling was going to be my primary source of income, so I bought a good bunch of it.  Then I got busy doing other things.  So, I wasn't able to saw as much as I had hoped before blue stain set in.   :-\
