So where are you guys from then ? Bob and Trader4 ?

Here is my plan, thanks to the input from you guys:

I am going to aerate the whole garden.
Seed it so they go into the small holes.
Put some starter fertilizer down.
Put a net over the garden to stop the birds eating the seeds.
Then water, water, water.

I'll also do it at the fall as I have plenty of seed.

I'm not 100% sure about how the sprinkler timer works.
Can one of you guys explain, I'm being thick here.
I'd only be having it on possibly twice in one day while I am at work.
With a normal garden sprinkler you attach the hose to the tap, turn on the tap and you have your sprinkler until you turn the tap off.

How does this timer work with the tap if you are out ?
