Repairing Damaged Grass Patches

As any gardener knows there are many ways in which grass can become damaged. Disease, weeds, overfeeding and over watering, damage from human traffic or household pets. Any of these can cause your lawn to lose, not only its look, but also it’s healthy colour and ability to grow.

Damaged grass normally takes on a characteristically different appearance from the rest of the lawn it inhabits and in most cases will be represented by discolouration, lack of growth and ultimately the patch of infected or damaged grass can die.

Damaged grass patches can be replaced in extreme circumstances but in instances of disease or fungal infection by such things as toadstools or puffballs, a less stringent but just as effective method can be used.

Removing fungi from your lawn normally requires you to quite literally brush it away and spray with a chemical weed killer or fungicide which will kill the culprit without killing off the grass. In some other instances such as having family pets that urinate on the grass, liberally watering the affected areas – which manifest themselves as discoloured patches – can return the grass to its original look and health.

As mentioned, in extreme cases, the patch of grass that is damaged may need to be replaced altogether.

Repairing Damaged Grass Patches

When it comes to repairing damaged grass patches there are a few basic tools that you will require to do the job, these are: a spade, a plank or board, some plastic sheeting, a light brush, some soil for top-dressing and some grass seeds.

It is best to remove the damaged grass patch by marking it with your board and digging around two inches down. If you can do this around the affected area it ensures that only the affected area is removed.

Source a fresh patch of grass from another area of your lawn where it will not be noticeable and remove it in the same way. You could if you wanted to, remove the affected patch of grass and plant new seed but this will take time to grow and bed itself with the existing grass so it is advisable – if possible – to take a sod of grass from another area to immediately replace it and keep the lawn looking uniform.

Once you have replaced the damaged piece of lawn you should liberally spread some fresh soil – or top dressing – over the area replaced and then brush it with a light brush so that the soil fills in the joins between the new and old grass and then sprinkle some grass seed which will cover over the lines when grown.

When this is done it is a good idea to water your lawn – if weather conditions allow – and do this lightly using a sprinkler system or hose with sprinkler attachment. Watering the lawn allows the grass that has been used to replace the damaged grass the opportunity to feed and also will help with the germination of the grass seeds. Once this has been done place your plastic sheeting over the area of grass that has been replaced and hold it in place with some pegs. Some people use bricks but it is best not to do this as bricks only seek to flatten down the grass around that which has been renewed.

Leaving the plastic sheeting down overnight and early morning allows for the seeds to sink into the soil and prevents birds from feeding on it. Remember to apply some lawn feed upon replacing grass as this helps the grass to bed itself in and grow.
