Hi green fingers. My bird nestbox - current home of field mouse - is about 8 feet above the ground but the climbing hydrangea makes a wonderful staircase! Regarding your lawn, I agree with Kate. I have a very small front lawn and I have filled it up with native wild flowers. In the spring it is full of snakes head fritillaries, snowdrops and the native small wild daffodils. I have sown yellow rattle to control the remaining grass and I have wild carrot, poppies, clover, selfheal, knapweed, cats ear, meadow sweet, birds foot trefoil, and buttercups with primroses, ragged robin and cyclamen around the edges. This is an ongoing project and each year it looks better. The bees, butterflies,ladybirds and hoverflies seem to enjoy it almost as much as enjoy watching them.
