need advice on backyard landscaping

Dear Experts,

Would appreciate if you can advise me on the

following

I have 3 trees in my back yard, all will

shed off leaves in winter (which leaves

behind a lot of mess to clean)

Landscape grass needs sunshine, which is

difficult to get in summer, as the Trees

shade a lot with green leaves.

Thinking of get ridding of grass and putting

landscape tiles around the tree and

and probably upto the patio. I live in dallas

is it a good idea? or do I need to get rid of trees to enjoy the backyard?

Any suggestions and any hints on what is

min $$$4 I am looking at? My backyard can be

classified as mdeium-small.

thanks in advance
