We built a rear extension and once this was all completed, the garden is now a disaster. No grass and rubble all over. I am clueless about gardening, but very interested. I would like to clear this up myself and regenerate grass.

Can someone advise how I do it (sorry for being daft).

1. What tools do you recommend
2. Is it is a good time to start in April? With planting the grass seeds etc.


Thanks!!
