overseeding and reseeding bare patches
Hi guys, I am looking for some advice, I have this 80m2 lawn, with a dog. I have dethatched and aerated and fertilised. I still need to take off some of those yellow patches.
I am planning on overseeding and top dress it with 70/30 sand and soil.
1. With those big patches, is it better to to use just top soil to reseed it?
2. What is better 70/30 mix or just topsoil to top dress a lawn?
3. Also I have worked out I need 600kg of topdressing for this lawn! Is that correct??
4. Do you guys topdress before or after overseeding and then mix it in?
NB. getting rid of the dog...i can't do. I will be setting up a barrier so the dog can't go on the lawn during this time.
I live i north east england
Any advice is much appreciated!
