I don't understand bark/mulch, which do I need to buy?
in Plants
I have just planted a row of hedges. I have been advised on here and elsewhere to now cover the area with bark mulch to retain moisture and prevent weeds. However, there are a lot of options and I don't understand the difference between them.
I'm not overly concerned with how it looks, I want the functional aspects of the bark.
What bark/mulch do I need to buy?

Bark comes in different 'grades' from finely composted, ground stuff, to chunky heavy stuff. They all do the same job, but the bigger the chunks, the longer they take to break down. It's also a great place for slugs to hide, so it will often depend on what you're growing as to whether it's suitable. Around most shrubs/trees and hedging, it's fine.
For anything more vulnerable, the finer stuff would be better.
