hi all,

i know nothing about gardening at all and i could use as much advice as i
can get about the biggest part of my garden the lawn

long story short its very uneven seems very compact and solid with bumps, i
would say there is more weeds than grass to be honest
and alot of patches with nothing other than solid soil


is there anything i can do ?
what products can i get to weed it ? ( they have to be pet friendly i have a cat )

any way to get some of the bumps out so its more mower friendly

regards
Lee
