Solving Soggy Lawn Soggy Lawn Solutions

Soggy lawns are something that causes many gardeners much concern throughout the course of the gardening calendar. Having a soggy lawn can lead to a wide variety of problems, not least water logging, which in itself if not dealt with can quite literally drown your grass plant's root system and result in it dying out.

Causes of Soggy Lawn

In the United Kingdom we are subjected sometimes to excessive periods of rainfall, which is one of the most common reasons for lawns suffering from too much water intake. Soils of varying types can suffer either from too much water intake or not enough but for the most part the problem is one of too much water.

Another common problem faced by gardeners is poor drainage. Poor drainage leads to excessive amounts of water being left in the soil with the outcome being - as mentioned previously - water logging.

A lawn that takes on too much water can feel spongy and under foot the soil can compact, which can cause additional problems when it comes to aerating and replacing damaged grasses.

Also surface water can lie and this can be a breeding ground for garden pests and also as the water lies it can become stagnant thus giving off an unpleasant odour.

Curing the Problem

Effective drainage in your garden is a must, especially if your garden runs on a hill or slope. Lying some simple pipe work in a herringbone formation can help to drain excess water to a lower point where it can be absorbed into borders where plants thriving on water can be planted. This is a good way of putting the water to a good use without sacrificing the integrity of your lawn.

Levelling out bumps in your lawn is another good way of ensuring that water is not allowed to pool and cause problems in specific areas of your lawn. If you do have bumps in your lawn it is advisable to try and level them out; this not only reduces the chances of water gathering in specific areas but it also reduces the chances of scalping when mowing your lawn. Scalping is the term of a horizontal blade coming too close to the lawn and pulling large chunks of grass and earth out as it goes.

If your lawn is close to your house laying a small pathway may help as will attaching an additional piece of piping to your down spout which can be routed to your rainwater drain to run off excess water. Diverting the flow of excess water away from your lawn where possible is a very useful practice indeed.

You might consider what is known as a Soak Away. This is a hole of a size normally one metre square and 75cms deep, which is filled with, gravel. The gravel allows for access water to be gradually absorbed into the soil beneath it at a rate, which the soil can cope with and in addition to this it can be used as an attractive additional garden feature.

The introduction of a narrow pathway on your lawn is also a useful idea as this prevents the grass sinking beneath your feet should you need to walk on it when it is wet. Walking on wet grass will compact the soil beneath it and can lead to pothole sized areas of grass being flooded under the weight of your feet as you walk on it.

@nomes - The main issue here is to find out what is causing the actual depression, it may be a case of builder's burying debris from the house (if a refurb was carried out), old tree roots etc. So, a bit of digging down should allow you to be able to assess the problem (make sure you are careful to avoid drainage pipes etc). Then, once you have found what is creating the issue it's a matter of removing any degradable materials then filling in the hole with a larger amount of soil (about three inches higher) and letting that settle for a few weeks before you level off and lay turf or plant grass seeds.

We have a small garden & in one corner nearest the house it's very boggy in winter & often puddles in the rain, in the summer it's constantly just a sunken area. We've tried packing it with earth & the grass grew back but it remained sunken. Can you help please?

My contractor put a membrane down before rolling turf lawn out.Is this normal?There are areas now which are very wet and the whole lawn never seems to dry out.Can I "fork" it to help with drainage?

@Caz - what was it like prior to re-turfing last year? If it was boggy before, then you may need to see about drainage.

We re-turfed our lawn last September after putting topsoil on it and ever since it has been a bog. I've not allowed the kids to go on it and it's really boggy with thin grass growing up now. Do I have to take it up and start again by putting sharp sand underneath for drainage? or can I rectify it with aerating it and adding sand?

@mouse - the dog may just acecerbate what is already a problem by making it worse, i.e digging it up etc. However, the problem is quite obviously there regardless of the dog and it sounds like it may be on its way to becoming stagnant and as specified in the article effective drainage in your garden is a must, especially if your garden runs on a hill or slope. Lying some simple pipe work in a herringbone formation can help to drain excess water to a lower point where it can be absorbed into borders where plants thriving on water can be planted. I hope this helps.
