We noticed the other day that some of the grass appears not to be grass, now we've looked properly and not just seen green stuff and thought it was lawn you can see that there's at least two or three patches of 'other' in every m2
We started to dig them out but now our garden looks like a mole paradise and is lumpy and holey 2 year old dd is loving just digging and finding worms but we want some semblance of lawn back!
If we re seed will that work? Can we dig up bits and re seed?
First things first: your Profile is out of date, if you now got 2yr old DD!
If I help you with 'lawn' problem, will you tell me why there is 'Jazz' in your name?
Ideally, you should dig over the whole area, but you probably don't want to do that. So dig out the offending items (whatever they may be) and rake the area to try and get it more-or-less level with the areas of grass.
Do you have other areas of garden where you could 'steal' soil from to level off any depressions there might be? Remove any large stones, and especially any bits of glass (before DD falls on them!) Then 'compact' the soil a bit (walking on your heels) and lightly rake again to make a level surface for the seeding.
What is the rest of the 'lawn' like? Does it get mowed? If you have a lawn rake, then rake over the existing grass (to make it stand up) then mow it. Get the bare-soil areas as level with the rest as much as you can, then scatter a suitable grass seed over the bare patches. In case birds or mice eat the seed, cover it with netting if you have any, if not - hope for the best! Water the seed in, and keep it watered in the unlikely event it gets so sunny it could dry out.
(Keep DD off the sown areas, but she will enjoy watching for tiny green grass shoots to appear, hopefully within a couple of weeks. I worked in primary schools for twenty years, including nursery, so I know what kids enjoy!)
