Replacing conifers with hedge
We have just had eight large conifers removed (they had probably been there 30 years and some were leaning dangerously after the recent Winter). We are going to replace them with a cotoneaster franchetii hedge. There is obviously a large amount of shredded conifer bits left. Can I use them as part of the planting preparation? I'm also thinking of bagging some to use in the Autumn as a mulch for heathers, pieris etc. What do people think?
