Plastic grass is not the answer, aren't we all meant to be cutting down or out plastic? What do you do with it when its life has ended or you just plain fed up with, throw it away to landfill.
My garden has grass, longish with clover and some wild flowers, patches of mud and yes a bamboo wind chime. We have two hedgehogs, a frog and even found some slowworms amongst a pile of rocks. A fig tree provides shelter from the sun when we need it Plenty of birds and I feel we have a lovely natural environment for a garden.
The reason for the chime is I like the calming sound it makes, so much better than the children one side shouting and screaming and the adults on the other side having a BBQ.
