Can I use bark chippings as a mulch in my planted wall?
North East England, United Kingdom
I have a small wall that gets really dry - I've already had to replace some plants in it this year due to drought, and am keen to try to avoid this happening again without me having to water it constantly. My gardening books tell me that some sorts of bark will deplete the soil of nitrogen(? not sure - from memory) but I don't know what effect this will have, or what type of bark to go for. I'm also hoping for a super-dooper quick reply, because I'm going out to buy it in about half an hour!!!!
