Topic tags/keywords: tip question

So what does everyone do with their sawdust once their collector is full? I would like to throw it in the yard or garden, is there any concerns with doing this? I know Walnut dust is an herbacide, any thing else? I was told to dump it in a pile outside for a year first, but I dont know why that would be. Am I missing any other uses for sawdust other than mulch? I have trouble throwing things away when it seems there should be some kind of use for it.

This last winter, I poured a mound of sawdust in the middle of the fireplace, place pine cones, other kindling over that, squirted with charcoal lighter fluid, etc.

I was surprised!! It ended up burning real slow and got really red like coals… and kept the fire burning a lot longer!

Most of mine was from Poplar & Oak… there was some Ply in there too… It burned really well!

I plan on burning more this next winter!

I use it for mulch for contolling weeds around my yard. Works great!

I have heard that it can attract termites…

I mix some of it with candle wax to make starter logs…gotta wrap it in paper. The rest gets a trip to the burn pile

A word of caution about bedding for horses.
Black walnut is taboo for the purpose.
The horses, I’m told by a horse owner, get a severe hoof disease from black walnut and sometimes have to be destroyed.


This how I came to score a great collection of large black walnut boards fro a guy whose wife had horses. She wouldn’t let him keep it under any circumstances.

I’ve heard mixed things about using it in yards due to issues with certain woods (if you don’t use those woods though then no biggy of course).

The best solution I can find is to create fire starters or even fuel logs (think duraflame but not as good) out of them. You could make a ton of them with a full bag of sawdust and give them as gifts in the winter.

I tossed some sawdust on a burn pile this spring. I am aware of the flash point of fine particles in places like a feed mill but this really surprised me! When I tossed the SD on the fire, it flashed like I had poured gasoline on it!

I use it as ground cover and to control weeds back behind my shed. We live on the north side of a high bluff and our back yard is heavily wooded. Nothing (except weeds) grows back there, so I dump my dust collector back there.

Never throw sawdust directly onto a fire!

Put it on BEFORE it is lit.

Many of you are correct to not throw sawdust on a fire. Check out this youtube video, it is not faked (the Mythbusters did an episode on it, and were able to replicate it).

I had been using it as mulch when I was doing nothing but oak, pine, and cedar. Since I started using Walnut, Osage Orange, and a few other exotics, I simply take it to a friend’s property and throw it on his burn pile.

i have a few people who come and pick some up for their animals, and the rest i am filling “big bags” with it, 1000liter volumes. or spread it in my vegetable garden for weed control.
but that’s not ideal since i read that wood fibers are complex to break down for bacteria, and they need alot of NH4 to break it down, wich causes your ground to become less fertile when you incorporate wood fibers!

Make sure you don’t have any treated lumber mixed in with it if you plan on putting it on the yard.
