We own an old clay tennis court which hasn't be used in years. how would i one-sidedly go roughly speaking fixing without paying a fortune for others to fix it? There is bits of grass and weed growing on it. Should I put down weed contract killer on the court? What would you do?
How do I keep hold of birds away...
Answers:    I think you should verbs all the weed and then shift to a hardware store and look to find some material to patch up the cracks surrounded by the clay. Since you will be filling within the cracks there is no genuine need to put down weed executioner because they can not grow back.
Pls oblige me on paver blocks?
