Does a dead tree still make for "green" firewood?

   / Does a dead tree still make for "green" firewood? #21  
I did this a couple of weekends ago. I always like the idea of burning firewood I just got. Something more satisfying about it. It really didn't burn well. It was Elm like most of the stuff I burn, and still had a few branches up top. I threw it on the fireplace when I had a good hot bed of coals and put on more overnight. The biggest was about a foot in diameter. The good thing is, it was still smouldering by morning, and I didn't really have to start a fire from scratch. I would not burn it in the stove on account of creosote, but could care less about the fireplace which has a 1/4" Stainless Steel chimney liner!

One of the best ways to cut firewood is to saw a ring around a live tree this time of year, it will die and be dry enough for next year. Standing it will not draw the moisture of a tree on the ground nor will it have as many bugs on it. Elm will usually slip the bark and makes excellent firewood. Not too big as it is he** to split.
After a couple of days of 40 below your elm will split just fine, but you will get a good workout.

Standing dead is OK sometimes, and you can tell right away when you saw into it and then split it. In good cases, it's bone dry. If the bark has fallen off and it's been there for a couple years, it's probably good to go.

Dead standing oak (DSO) is excellent firewood, especially where the bark has fallen off. It's best if it is harvested during a dry spell. A couple of years ago, I goofed and didn't get wood in ahead of time and that's all we used all winter and it was great. (Red oak, here.)

I sure am learning a lot from everyone here, especially about different woods. I have 90% oak: post oak and blackjack oak. These trees are mostly small with the tops not exceeding 30' tall. Many times they die and the tops break off and fall, leaving a 12" - 16" trunk about 15' to 20' tall. After leaving them in the ground for a year, they easily push over with my tractor and the rootball pops out of the ground. I like to push them over during the winter because most remaining sap has gone to the roots. The rootball may be heavy with moisture, but the main trunk seems very dry and requires little seasoning. I normally buck them into 16" rounds and stack them for one season before splitting, but many/most of them would be fine for burning the first season after cutting. One of these round that is 6" to 8" in diameter makes a perfect back-log for my fireplace and will last almost all day long with smaller logs and splits burning in front of it.

I have resorted to burning some rounds of white oak, red oak, and wild cherry from the dozer pile that I cut up last weekend. Some of it is really heavy/dense, and I was concerned it might have too much moisture in it. However, it seems to be burning just as fast as the split seasoned red oak from last year, and without any noticieable creosote. I'm guessing I'm not getting the BTU's I would get if it was seasoned, but the house it still warm. I will be cutting more during the warm spell this weekend!

If I cut down a dead tree, or cut up a fallen tree propped up on another, is it still considered "green"?

It just depends. The problem is I can't figure the depend part.

We have what I think are White Oaks on our place. If these things die, say from a lightning strike, they dry out and rot FAST! I just had one of these tree blown over a few weeks ago and I know that tree was dead for less than a year. These trees die but rot then dry again. The rot ruins them for firewood and makes the standing tree very dangerous. The tree that just blew down could be burned since it seems very dry but there is very little mass to the wood from the rot. Chalk is stronger than this wood once it has rotted which makes cutting down one of these trees so dangerous when they have died. You just do not know what you will find under the bark.

When these tree rot, they rot from the center out. The wood feels like a wet sponge at this stage.

Now, the Red Oak on our place is awesome. It rots very slowly even when wet. We still have Red Oak on the ground from Hurricane Fran which was almost 20 years ago.

TWO summers back, we had some trees bulldozed to give us more garden space AND get some trees away from the house. Over the last six months, I finally got time to start cleaning up the trees and making firewood. These trees have been pushed over and the root ball pushed out of the ground. Some trees were so dry I could have burned the wood right after splitting. Others are wet and will take time to dry. The one huge White Oak that was pushed over is wet with some rot but I think I have split the wood in time to get some ok firewood after it dries. Some of the Red Oak was dry enough to burn while other batches needs some drying time.

So the answer is it depends and the only way to know is to cut up and split the wood.

To help dry out some of the wood, this winter I started stacking wood on the south side of the house. Our roof over hang keeps most rain off the wood and I will use a tarp if we get rain. The southern exposure keeps the wall very warm and warms up the wood as well. This seems to act a bit like a drying kiln. Not perfect but better than nothing.

The wood we are burning right now I split starting in August and it has been fine so far. The only wetness I noticed was in some wood yesterday. The wood was sitting in front of the wood stove for a few hours and I saw some wet spots. The wood burned into the over fire zone on the wood stove thermometer we use. The wood did burn as high as other wood but it was certainly hot enough. Well, it was so danged cold yesterday and today, that it did need to burn hotter! It was 6 yesterday and 10 today and the woods stove has a tough time keeping up with these low temperatures. The house was 74 yesterday morning but down to 68 this morning even though the stove was running 24 hours a day. Thankfully, the temps are rising and will be above freezing today and into the 60s over the weekend! :dance1:

The water supply froze this morning! :shocked: The well house was in the 40's but the water supply line from the well house in the exterior wall. The plug of ice melted by 9:30. First time this has happened and I hope the last...

The shorter the length of wood, the faster it will dry.

Later,
Dan
