When grass is under stress it can lead to a number of lawn diseases taking hold. Some will cause minor cosmetic damage to the grass blades, others can kill of large areas of the lawn, ultimately ruining the lush green appearance. There are various different factors that contribute to the development of disease in domestic lawns, they are:
- Weather Conditions – damp and humid or wet and cold conditions are conductive for disease.
- Incorrect Mowing – if the lawn is being cut at the wrong height or with a blunt blade.
- Lack Of Nutrients – grass, like any other plant, needs feeding. A shortage of sufficient nutrients at the correct times can leave lawns stressed.
- Insufficient Cultural Treatments – regular aeration and scarification will help deter disease by improving the air, moisture and nutrient penetration to the root zone.
Lawns can be made more disease resistant by applying a balanced nutritional programme all year, combined with regular cultural practices such as scarification and aeration. The treatment of any occurring diseases can depend on the current condition of the lawn, time of year and stage of disease.
