choosing Mittleider garden sawdust

Mittleider garden sawdust

When it comes to gardening in grow boxes in your Mittleider garden it is extremely important to choose and obtain the correct sawdust.  Not just any sawdust will work as your Mittleider garden sawdust.

Most any type of tree will work, with the exception of black walnut.  Black walnut has toxins in it called juglone that can stunt, deform or even kill other plants.  If the sawmill cuts black walnut you should avoid that sawdust, even if it is free.  Do nut use walnut for your Mittleider garden sawdust for any reason.

The only kind of sawmill that you should consider as a good source of sawdust is one that runs a large diameter circular saw blade.  The blade kerf is wide enough that you will get the correct size of sawdust particles.  See the video at the bottom of this post to see the correct size and an example of a sawdust that is far too fine.

Band saw sawmills

Sawmills that run band saw sawmills are becoming popular and can be found on homesteads where folks make their own lumber. Unfortunately the kerf is much smaller on these types of mills and the sawdust particles are too fine for our purposes and isn’t a good source for our Mittleider garden sawdust.

The size of the sawdust particles is important

Have sawdust that is too large, such as wood chips, will result in poor drainage and souring of your growing medium.  This can prevent water from getting to our plant roots and even cut off oxygen.  Either can surely kill your plants. (Remember the 6 laws of plant growth?) Planers or even wood chippers would be a common source of wood chips that are too large.

Just as too large can kill your plants, so can sawdust particles which are too fine.  This sawdust is would be collected from table saws, band saws, and that cool saw you see in stores like Home Depot and Lowe’s.  This sawdust is far too fine and can cause compaction.  Once hard and compacted your plants can struggle to get water and nutrients.  This fine sawdust is often free, but it can cause real problems in your garden and needs to be avoided.

What if there are no sawmills near me?

If you’re unable to locate sawmills near you and are determined to grow in sand and sawdust then you can buy equine pellets. When the pellets become wet they turn into a usable pine sawdust that works well.  It takes just a few minutes to transform the pellets into a usable sawdust.
