Wood shaving in potting mix?
« on: July 13, 2020, 06:32:45 PM »
Just got some untreated oak wood shavings and am wondering if it is any good to put in potting mix. I know oak is high in tannins. Is there any benefit of putting it in potting mix?

If you listen to Laguna Hills Nursery (videos on YouTube), you shouldnít use any wood products (compost) in potting soil. 
Iíve just started to trial this recommendation, which is basically contrary to the entire Ag industry (potting soil companies). 
Iím using 50% peat moss and 50% pumice (alternate equivalent coarse perlite is easier to get than crushed pumice) for potting soil.  There is another potting soil mixture of 1/3 peat moss, 1/3 crushed pumice (or coarse perlite), and 1/3 sand, charcoal, and clay that results in less compaction over time.
btw... they recommend sand as the best growing media, but that weighs a ton.

I would try to not use fresh wood shavings/sawdust in potting soil but I would consider spreading it under trees with microorganisms to slowly break it down, convert into food for your fruit trees.
I do use composted wood, coir, clay, charcoal and sand or rock dust as ingredients in potting soil.  To use a lot of spagham, perlite, etc. you will need more chemicals and the other thing is that if you are going to plant the trees out then they will be going into a soil that will be very different from whatís in the pot.  That doesnít seem good to me.

For Sand, I heard that it has to be coarse sand as common sand is too fine and results in increased water retention and poor drainage. 
Do you know any good source of coarse sand in orange county?

Beach sand is coarse.
You can buy all purpose sand then shift out the coarse sand.

Iím trying to minimize watering so Iím using plaster sand.
Still need to water peach and medium cherimoya every day.

If you are trying to minimize watering then why donít you use clay? Sand dries out waaay faster than clay.  Sand serves a purpose but itís hard for me to think of a medium that needs more watering.

I wouldnt use oak because of the danger of spreading Armillaria.
Also if you mix wood with soil,you deplete you soil of Nitrogen( at first) as wood doesnt contains nitrogen,just a lot of carbon.
In order to be composted it needs a lot of nitrogen and bacteria,fungus,will take all the nitrogen for themselves to break down the wood and you either add more N to the pot or your plant will starve.
