Camphor tree shavings
I recently had a camphor tree cut down and saved some of the shavings when they ground the stump. If I use these around my flowering plants to keep down weeds, will it harm them?
As long as your plants are mature it should not have any adverse reactions. If you have some concerns about the shavings robbing nitrogen from your existing plants you can incorporate them into a compost pile for a season and allow them to decompose a bit before adding them to your garden bed.
