How about replacing it with a meadow? "There's almost nothing quite as
lovely as a meadow full of wildflowers and grasses swaying in the
summer breeze, butterflies flitting around, bees buzzing, birds singing
and the sun shining."

Hi,

I am new to gardening.... I have a house in Portugal and it has a
backyard of 1.200 square meters full of weeds. Once or twice a year I
have to ask someone to go there and with a tractor to clean the land. I
am wondering if there is any type of grass (or any other stuff) that
will take the space and without growing too much (max around 15 cm)
will make it green.

Cheers,

PA
