How to revitalise your lawn after flooding

How to make sure your lawn bounces back following extensive rain and flooding.

We’ve seen a lot of rain over the past weeks in the UK. If you find yourself in the unfortunate position of having your lawn flood, there are necessary steps to prevent contamination and allow the lawn to return to its best condition.

When to start

Following flooding, all repairs to your lawn will take time. In some cases, you may need to hang fire on repairs to await more favourable weather conditions as taking immediate action could do more harm than good.

This often means waiting until the spring. During this time, take great care not to walk on saturated soil and do not mow any wet grass.

There can be no flood water left on the lawn for repairs to begin in earnest. After the water has subsided, the first thing to do is remove any debris left on the lawn, by using a rake.

Aeration

Following a flood, the greatest threat your lawn faces is suffocation. So, once all unwanted debris has been removed, quick action needs to be taken to aerate the lawn as the lawn surface dries.

Aeration is the process of using professional equipment to penetrate your lawn’s surface, opening it up, and allowing air to reach the grassroots. This is vital following a flood as the lawn will have been deprived of air and may even have become compacted.

Time dependant: Scarification

Dependent upon the time in which the water has laid on the lawn surface, it may be necessary to complete some scarification to remove organic matter that was left on the lawn’s surface.

Organic matter is important to eliminate as it can prevent the grassroots from penetrating the soil properly. This means your grass can’t receive the right nutrients to stay happy and healthy.

Remove silt

After leaving the lawn to dry naturally, you may have also found a deposit of silt left on the lawn’s surface. In such instances, you’ll need to lightly rake over the layer and complete further aeration.

After this, apply a helping of sand-based top dressing to break up the silt. Once raked over the lawn surface, this will further improve drainage and soil structure by filling the holes that were created during aeration.

Fertilisation and overseeding

To allow for your lawn to return to its prior condition, fertiliser application is likely to be required to allow for existing grass to regenerate.

Once temperatures allow, it may also be necessary to complete some overseeding to achieve a denser grass cover. This is important in preventing an increase in moss and weed infestation, as these are more likely to form should the grass cover remain patchy.

Returning your lawn to its former glory

While the full repair work may take time, using the right processes, and equipment will result in a perfectly manicured lawn, that is likely to be even better than before.
