New house but from photos the lawn needs some help and so I am planning on doing the following but not sure in which order is best or if some steps could be concurrent.

• Top dressing the lawn with black earth

• Reseeding

• Fertilizing

• Applciation of Scotts GrubEx (understand white grubs are a problem that nematodes have not handled

Suggests will be very appreciated.

Disclaimer: I've got a lot to learn and there are much more experienced users on this board. Listen to them first.

I'd say you could probably do this all in one day. If it were me I'd throw the GrubEx down, dress, seed and fert. Probably in that order.

I would do grubex, fert, crabgrass preventer. Then in July, seeds.

How long between each step and where does the top dress fit in?

Thanks

Being in Montreal you could take this plenty of different ways because your summers are rather tame

Usually, @g-man and I agree, but this time we're a little different. I would wait until it's all green and you've mowed at least once, if not twice, to fertilize. no point in doing it on dormant grass. But you can do the Grubex first, anytime, as long as the ground isn't frozen. Pre-emergent may end up being the second thing you do. I would aim for no later than a week after the Forsythia bloom, ideally.

Green is right. I assumed it is 60f and forgot to adjust to your weather/frozen ground. I have visited Quebec for vacations in July (and plan to go again this year). They told me they have two seasons, winter and July.

Since I gave you a bad advice, let's take this from the start. Could you post some pictures? Why do you think you need seeds?

It has stopped raining (10 days after it's stopped snowing) so here are some indicative photos of the mess (I mean lawn).

Thanks for asking.

First image looks thin, but there is plenty of grass in there. I would treat it like we do after a renovation, with frequent low quantity of nitrogen (~0.2lb of N).

The second image, top right areas, that looks rough. It looks like it is matted down from all the snow. Some times these areas recover after the winter with some nitrogen.

But for nitrogen, we need make sure the soil is not frozen, as green pointed out. A quick online check for Ontario said it was 0C at 4cm. I think we should wait for some improvement in the soil temperatures.
