Whataboutyou! This is Robbie from Premier Lawns, the lawn care company based in Belfast
Northern Ireland today I'm in a customer's garden look we scarified
before the lockdown we didn't do any aerating at this one but a lot of
people have been asking me why we put the iron on afterwards so I'm gonna
show you this lawn and then talk you through the reasons for it. So stick around
So there's some scars in places they'll not be long coming back.
You can still see the lines from the scarifiyer.
We scarified this two or three weeks ago just before the lockdown
and they're starting to come back nicely. The grass is
lovely and dark green from the iron that we put on and just as it starts to go
away the the fertiliser is really starting to kick in and that's when I
really start to see a lot of recovery in the lawn.

This is a question that comes up very regularly in the comment section
of my video - how to kill moss in the lawn and why do we put the iron on after we scarify
and not before. In lawn care we use a
product called chelated iron and this comes in the form of iron sulfate,
soluble or iron for short, it comes in other forms, though for my lawns this is what
I use and this is what I'm going to be talking about today.
Iron is a fantastic product for your lawn so look anything, too much of it as a bad thing
and you need to keep it away from a patio as its stain is super hard to remove.
Iron feeds the lawn, it does this by helping the grass to produce chlorophyll
that's the bit that makes it green and it also has the added benefit of controlling moss.
Now something that I need to make clear and to help you understand why we
apply the iron on afterwards the iron does not kill the moss it burns it and
this is the key reason to why we apply it afterwards.
Due to the lockdown I haven't done any mossy lawns yet this year. I had some
planned and coded for in the works but due to the lockdown I've had to stop.
Daniel my helper is currently in furlough the recycling centers are all
closed so can't get rid of the waste and it's not safe to work on a two-man
team so at the minute all the lawn renovations are stopped. I get a lot of
questions asked me why we don't lift the debris between passes? Generally this is
unneeded, we use professional tools I have an Elite 501 scarifyer and it just
eats up the lawn. There are times of course when we will lift between passes
but this is on an ad hoc basis as and when required depending on the lawn.
This is a picture of a soil profile it will hopefully help me explain why it is
better to apply the iron afterwards to a lawn. If you put the iron on before
scarifying a lot of the time it'll only burn the surface moss. This circle shows the
thatch layer of the plant and this bit is key! The moss grows in the thatch layer and
the moss that is growing in the thatch layer will be unaffected if you apply the
iron before scarification.
If you wait until after scarification the thatch layer will be opened up and the iron has a better chance of penetrating right
the way down into the thatch layer as it'll be reduced from the scarification.
This is why I apply the iron afterwards as it just works better
although there are times when you wouldn't apply the iron afterwards
for example if you were feeding a lawn - but that's a topic for another video!
