I got fed up with seeing the grass and weeds around the base of our citrus trees so I raided the free timber bin at Bunnings for the packers out of the fence palings packs, cut up a hardwood stake that wasn't being used and made my own tree surrounds.

Steps
Step 1
I cut each packer in half as they were roughly 1m long each and cut up an garden stake that we weren't using into 100mm long pieces (same height as palings). I had left over timber protector from my previous garden project so I painted all the pieces with that to help prevent rot etc. I screwed the pieces together with 40mm climacoat screws that I had left over from another project.
While the timber protector was drying, I weeded and fed the citrus trees and the following day, I put it all together - dug the surround in a little, then added extra garden soil and some mulch (both from Bunnings). I was careful to keep too much soil and mulch from around the base of the trees.
I hope this helps someone looking for a cheap and easy solution to a similar problem 😊
