How to Repair Over Fertilised Lawn

Over fertilisation is damaging to a lawn: it causes grass to wilt and exhibit brown spots, creates salty soil, and destroys the overall look of the lawn. Over fertilisation can result from fertiliser with too much nitrogen and failure to follow the application instruction that come with the fertiliser package.

The keyword when repairing an over fertilised lawn is watering. Watering cleanses the soil of harmful elements that cause the grass to be sick. But depending on the end result of over fertilisation, there is a certain process that DIYers can use as a guide to repair the lawn.

Repairing Over Fertilised Lawn with Dead Grass

With a garden rake, remove the dead grass from the lawn. If fertiliser granules have been used, remove them from the lawn before the soil soaks them up. If the soil has a white color to it, it means that it has salt buildup. The solution is to remove the top layer of the soil and dispose of it. Then, water the lawn to flush the soil of excess salt.

The next step is to layer new topsoil onto the areas where salty soil was taken and then level the new soil with a garden rake. Seed the new topsoil with grass seed or replace with sod, following the instructions that come with the package. Remember to keep the area moist that when planting sod. Finally, water the new seed until they germinate.

Preserving Green Grass When Over Fertilisation Occurs

Water the lawn slowly and deeply for at least 30 minutes to remove the fertiliser from the blades of the grass, preserving their green color. Remember to cover the entire lawn to wash out the fertiliser evenly. After two or three days, water the lawn again. Repeat the process twice every week with at least one inch of water each session.

The best way to percolate down into the soil is to water deeply and slowly. Watering heavily and hastily only creates chemical runoff. Mow the lawn two weeks after the accident to avoid exposing the blades to fertiliser that creates burn spots. As a reminder, mow only dry grass and cut only one-third of the blade height with each mowing session to lessen stress.

Repairing When Grass Turns Yellow

A buildup of thatch happens when over fertilising kills the enzymes and beneficial microbes that break down grass clippings. Before providing a solution, check first that the thatch buildup is brought about by over fertilisation and not another occurrence like the grass going dormant for winter. A soil expert from an extension office can reveal the real cause of the grass turning yellow. When discovering that the culprit is over fertilisation, begin by watering the lawn to wash away the nitrogen that turns the grass yellow. However, if the lawn is already watered too many times before the problem, irrigate it less frequently.

Next, apply a detaching product to bring back microbes and enzymes to the soil. When reseeding and working compost into the soil, do not forget to aerate the soil to help bring oxygen into the compacted areas.

Reviving Over Fertilised Plants

DIYers need to clear the plant's soil of visible fertiliser. Remove topsoil if it has developed a white crust made of salt. Next, leach the soil with water to wash away fertiliser. Do this by flooding the soil around the root system and let water drip at the base for 30 minutes.

With scissors, trim the burned leaves, which usually have brown spots. Cut off any wilting leaves, too. Removing burned and wilting leaves prevents the plant from attracting pests and diseases. When it is time to fertilise the plant again, use a fertiliser low in nitrogen to avoid the harmful effect of over fertilisation.

Preventing Fertiliser Burn

As the saying goes, prevention is better than cure. Those who know ways to prevent fertiliser burn can avoid unnecessary expenses and keep the grass green and healthy.

When using any fertiliser, follow instructions that come with the package as fertilisers vary in strengths

Check the Health of the Grass Before Applying Fertiliser

Grass in poor condition requires very light fertiliser application; using heavy fertiliser on weak grass can lead to fertiliser burn

Choosing the right fertiliser to use in the lawn is a step to keeping the grass in great condition, and many niche websites about lawn and gardening recommend organic fertilisers as safe fertilisers to use. As an additional reminder, do not fertilise a lawn that is severely affected by heat, drought, or disease.
