I have been treating it as a shady lawn and getting an appropriate grass
seed mix for reseeding. I have recently reseeded grass is growing very
well but the existing grass is not growing much. When it was
germinating was watering twice a day but now watering every other day.
There is some moss and it needs feeding so I have just ordered some MO
Bacter Organic Lawn Fertiliser.

The fertilizer will help.]


I seem to be getting there but have a few questions.

1) Is it correct to treat it as a shady lawn or am I using the wrong
grass mix?

You would probably be good either way.

Those mixes are typically tolerant. Here you can find mixes for sun
sun/shade, shade, dense shade. For what you describe, anything other
than dense shade should be OK.








2) How long should I cut it? Currently, I am setting mover to 60mm but
thinking 40 or 50 may be more appropriate. I'm currently mowing once a
week (ish, sometimes a bit more frequently, sometimes a bit less).

Cut it as high as your mower will go. The grass will better shade the
soil, helping retain water. The roots will have more energy to grow.

Agree, a higher cutting height is generally better. It also helps
keep weeds out. It also depends on the grass and how you want it to
look. I'd stay with the 60 or maybe try higher.






3) in this weather is watering every other day about right.

That's way too often after the newly seeded grass is growing to mowing
height.

I tmay not be too often, depending on the temperature and rainfall.
If it's 90F+ and no rain, even if newly seeded grass is at mowing height
it probably needs to be watered every other day. You can gradually
back off, go to every third day.



You are encouraging shallow root growth. Give it 5-7 days
between deep waterings (1") unless you see it start to dry out.

That all depends on the conditions. If it's 90F+, good luck with
any lawn staying green with 5 to 7 days between watering. Around
here, you'd need to water it twice a week, minimum. I see a lot of
people saying one inch once a week, but I think in reality one inch
goes deeper than typical roots and 1/2" or 3/4" twice a week is
better. Also few people have any idea how much water it's really
getting. You need some tuna cans scattered around to find out.
With sprinkler systems, many people run them for 20 mins and think
they've done something. My system takes about an hour per zone to
get around 1/2", maybe longer. And if you're paying for water, that
adds up quickly.
