I set out 6 raspberry canes 3 or4 years ago. I mulched it with some sawdust, but didn't put on as much as I should have. I pretty much just neglected it ever since.
I decided to clean it up today. It took about 6 hours to pull the weeds and put 17 wheelbarrow loads of sawdust on.
They would probably be a lot thicker if the weeds hadn't been choking them.
I got my workout for the day.
