Hello, I am having trouble with some standing water on the lawn, I was going to hollow tine aerate the lawn to try and relieve this. My question is, do I need to fill the holes that the aerator leaves, if so what with. Or do I just leave the holes as they are?

TIA for your help.

I too have had trouble with standing water on two of my three large lawns.
After particularly heavy rain I am left with about four areas of standing water usually where there is a slight depression
in the surface.
I am also conscious that my garden is at the bottom of a slope which I feel is responsible for the water draining towards us.

Airating the lawn with an hollow tine tool does just that. It aerates the Lawn.
In your case I could just imagine the holes filling with water (although it should help some.

I do feel that you need to add a drainage system to your lawn to help get the water away. That is what
I did after recommendations and it has worked.

My system was put in using cley drainage pipes about 75mm in diameter, although you can now obtain plastic.

This may help:

lawn sand assuming you don't normally have standing water. We've had so much rain lately that water is standing where it normally doesn't.

Hi thanks for the replies, the water appears to be collecting by the childs wendy house. Im assuming it has compacted there, so when I hollow tine, I need to put lawn sand in the holes is that correct?

you don't have to, but it will help with future drainage.

It is worth reading this page: https://www.lawnsmith.co.uk/topic/aerat ... e-the-lawn
Advice there is not to bother with filling the holes with sand.

I find that a very good site when I'm looking for advice on lawn care.

Aerating the soil might be a short term solution but when it rains heavily again the standing water will return. You should try and get rid of the slope, if that's impractical, remove the turf, dig down to 'un-compact' the earth and incorporate lots of gravel and organic matter to create better drainage.
