I seeded a lawn (from scratch) about 3 weeks ago. The grass is no
between about 7 & 13 cm high. Should I give it its first mow or wait
Also there is a certain patchiness (I probably could have distribute
the seeds a little more evenly); will this even out over time or ar
there some measures I should take?
Thanks in advance,
I'm no expert, but I have read years ago, that one should mow newly
seeded grass as soon as there is something to mow, and raise the
mower for the second mowing, etc until you have grass at the desired
height. This is supposed to help the grass spread.
You don't specify what type of grass it is, but for typical cool
season lawn grasses, It should be mowed when it's about 7.5cm.
Cutting it does encourage it to grow faster.
As for being patchy, it depends on 2 things. One is what exactly you
mean by patchy. If it's small spots of 10 cms or so, yes the grass
will grow to fill in. If it's patchs of a meter in diameter, then
likely not, or at least not at a rate you will like.
The other factor is the type of grass. Kentucky Bluegrass will spread
via rhizomes, so it can fill in larger bare areas over time. With
clump type grass, eg fescues, the individual plants can expand to fill
in smaller areas, but it can't cover wider areas like KB will. If you
have an agressive grass like Zoysia, it can spread and cover anything
given enough time.
