If your lawn has been overfertilized, either because the wrong concentration has been applied or because of an accidental spill, you are probably worried about the dry patch or patches that appear almost instantly. The symptom is called fertilizer burn for a reason – fertilizers are very harsh substances that encourage growth only when applied in the right concentration, when it comes into contact with your grass in undiluted form, it dries out and kills the leaves. There is no reason to despair, though – here is how you can resuscitate your overfertilized grass:
- The first step should be a meticulous check of the grass roots – this is very important because the check will tell you whether the spillage is only superficial or it has affected the roots as well. If the roots seem healthy, all you need to do is to water the grass – it will recover by itself, especially if you are using an organic fertilizer Denver stores sell. If the roots are affected, the only way to solve the problem is to remove the dead plants;
- Watering – the next step is to flush the surplus fertilizer with a copious amount of water on the lawn. Pay increased attention to the affected area – add about an inch and a half of water every day for the next five days or so. Water the unaffected areas as well to flush any excess from the entire lawn;
- Rake the grass – when new grass starts appearing, make sure to rake it thoroughly to remove any dead residues;
- Overseed – if you have too many plants that are unable to recover, sprinkle new seed in the bare areas, while continuing to water and clean the area until the leaves become evenly strong.
