Lawn Zing

I live in a row of 4  houses and we share our outside lawn. which must be about 80m long ,20m each. we have just all paid to have it relawned with rolls of grass and very nice it is to  . 

I havent a hose pipe at home so i have bought my watering can back and my section takes about a dozen watering cans and trips to the kitchen sink to water, i notice no one else is watering theres but im sure it will be ok. My wife and i where just talking about it and she said if you are looking after ours why dont you find out what grass really likes and give it a 'treatment' every now and again and see if we can get our section sparkling healthy and green for a bit of fun. So she has given me the challenge!

Help i dont know much about treating lawns for the added sparkle! would it like a comfrey tea? i can do that lol.
Any ideas of what gives grass that added zing please let me know 

Cheers MW.

From an agricultural perspective I would grass nothing after the beginning of September 

sulphate of ammonia 

not much tho.

Yeah that's it a light sprinkle its really potent stuff.

I bet you will have to cut your lawn 3 times more than the others :-)
