Spiky lawn

Hi, for the last 2 weeks (June ‘11) my lawn seems to have developed a huge number of grass stalks. Previous to this it was the best I had achieved for a long time.
I have not cut it short (summer cut) but have cut it half way between a winter top snip and the summer 15mm. It was looking lovely, lush and almost completely weed free. I fed it in April/May after using a Ferrous Sulphate mix a couple of weeks earlier and removing the blackened moss.
Now I seem to have innumerable spikes of grass stalks all over the lawn - can you tell me why and what action I need to take.
I double (cross) mowed this w/e but without lowering the rotary mower and it's got 95% of the stalks but will they return even worse?
Should I feed the lawn again?
All advice greatly appreciated - thanks

 

Good evening Smigin and welcome to the site. is it grass is it green? and does it look the same when cut? Then keep it cut and and don`t worry about which type of grass.:D:D

 

The stalks are just the grass trying to flower and produce seed heads. It's a seasonal thing, June is the natural flowering time for grass.
Nothing to worry about, just keep cutting them off with the rotary mower, once the grass flowering season is over you shouldn't see too many more.

 

Thanks Diatheplant, Trunky - as you can tell my green fingers are more a shade of pale lime at the moment.

Whilst I've had a garden a number of years weed control was the limit of my experience. Now I have the time and inclination I want to get it right.
(I'm sure there'll be more novice like questions as I try to be more adventurous :o)
