A few years ago we ( because of both being at work) decided to exchange the lawn for an area of bark, so we made the garden into a kind of woodland feel, with plants dotted about here and there. We love to see birds in our garden, and i hope that the added insects will help, along with better hiding places for frogs etc. I know its not the conventional garden, but do you think we did the right thing.
Doesn't matter what we think. The question is, do you like it? Obviously you do, and thats all that matters. I think it sounds brilliant. However, you may need to keep the bark topped up, as it will eventually break up and you will end up with a very rich soil. I bet its lovely at this time of year - snowdrops, and then bluebells, primroses, etc.
As said in the previous post, if it suits you it's great. I have an area of my allotment covered in bark. Of this I am sure, top fruit love it! Raspberries, gooseberries, cuurants and the like appreciate the lack of weed competition and the moist soil.
This year I am going to plant asparagus and cover the area in bark. I reckon it will work a treat.
Good luck and look for ways that alayer of bark cant benefit a huge pile of plants.
