Paragraph 1

I have recently planted a hedge.  Living in a rural environment, I made the decision to plant only native species, including field maple, hawthorn, hazel, dog-rose and blackthorn. In time this will grow to form a dense hedge whose primary purpose is to form a windbreak, but which will also be attractive both to me and to wildlife. In the two years since planting, a number of hedgerow wild flowers, such as scabious and knapweed have already begun to colonize the spaces between the growing shrubs. Of course, if allowed to grow too freely, rank weeds and grasses will limit the growth of the hedge and need to be removed. This is done by hand, without the use of herbicides, in order to encourage bio-diversity.
