Three Ways to Use Logs In Your Garden (Instead of Throwing Them Away!)
Rotting wood and logs are a great addition to the garden.
I see so many people – particularly in South Florida – dragging logs and palm branches to the side of the road in bins for trucks to haul away.
Quit doing that! As I cover in my book Compost Everything: The Good Guide to Extreme Composting and in glorious color film in Compost Everything: The Movie, wood is good for the soil. It breaks down into excellent humus which holds water. When you have poor soil, you want to increase humus and soil nutrition, not send it off to the city dump.
Here are three ways to use wood in your garden and increase your soil fertility long term.
1: Use Chunks of Wood for Garden Boundaries
When my Dad and I built The Great South Florida Food Forest Project, we picked up all the yard “waste” we could find from nearby neighbors and then piled it up, lining the pathswith the thicker branches and logs.
In a very short period of time, those logs started breaking down into rich soil.
Most of them aren’t there any more and need replacing… but you wouldn’t believe how nice the sand looks where they used to lie.
The image on the left shows what the sand looked like before and after we piled up organic matter.
People love to complain about how “bad” the sand is down in South Florida and how nothing grows there. Yet they rake up all their leaves and throw away logs.
2. Make Hugelkulture Mounds
A friend of mine cleared a big area of her yard to open up the light for her edible crops, to get rid of the invasive trees, and to make sure hurricanes didn’t send any 2,000lb chunks of tree through her roof.
Instead of making a big burn pile or sending them off to the city, she made a gigantic pair of hugelkultur mounds.
She dug trenches, filled them with wood, then took all the mustard-covered soil on the left and buried the rotting wood.
Now they are rich, flower and food-covered gardens.
They can improve the soil for decades.
3. Turn Those Logs into Biochar
When life gives you fallen trees, why not turn them into charcoal and improve your soil for not just decades… but generations!
I burn big open piles because I don’t want to bother making kilns or getting fancy. Plus, I want to fight global cooling.
Though turning charcoal directly into your soil will suck up nutrients and drop your yields, soaking the charcoal first in something like compost tea will allow it to become a resource bank for the soil. Charcoal pieces hold in fungi, bacteria and nutrition like little condominiums, thanks to the intricate pore structure of wood.
Steven Edholm recently shared some tests he did in three garden beds and I reshared it here.
It’s time to think differently about fallen logs and branches.
Don’t view them as “too big for the compost bin” and send them off.
Every time you do that you are exporting fertility from your property. Don’t.
Instead, use one of these three methods and you’ll not only improve your soil, you’ll keep useful material out of the waste stream.
I’ve done all three and my plants love the help. You can too – and can even make it look nice. I once grew a nice cabbage inside a rotting chunk of log I picked up by the side of the road.
Worms, bacteria, fungi, beetles… all of these live in and out of the rotting wood and will happily break it down into rich soil for your garden.
Think differently about fallen trees and you’ll improve your soil long term. I guarantee it!
