Let us use this post as a source of knowledge on how to get rid of some very common lawn diseases.
WHAT CAUSES LAWN DISEASE?
Numerous factors are responsible for lawn diseases in kikuyu lawns and lawns with couch grass. Environmental stress is the number one reason for load by others, such as improper lawn care, fungal pathogens, over- and under-watering, weather conditions, and so on. Amongst all of them, fungal infection is the most prominent reason that arises due to a lack of maintenance.
You must have a proper understanding of your turf type and also the diseases that it can face. Some common reasons behind lawn diseases are listed below.
Poor drainage
- Excess water encourages fungal growth and weakens the roots, promoting disease.
Drought stress
- Conditions can cause weakened turf and make it more susceptible to diseases.
Over-fertilisation or under-fertilisation
- Imbalanced nutrition can create an environment where diseases thrive.
Improper mowing
- Cutting the grass too short or with dull blades can stress the grass blades.
COMMON TYPES OF LAWN DISEASES
WINTER FUSARIUM
This lawn disease is also known as fusarium patch, and it is a common fungal disease that affects cool-season grasses. It mainly thrives in the winter season or wet conditions, and you can trace it easily through small circular patches of discoloured turf. White or pinkish fungal growth also appears due to this disease during the rainy season. It mainly arises due to poor drainage or water pooling in the lawn area. Over-fertilisation also gives birth to this problem, and the prevention tips given by turf suppliers are provided below.
- Aerate your lawn to improve drainage and reduce compaction.
- Avoid applying too much nitrogen fertiliser.
- Do not overwater cool-season grasses during winter.
DOLLAR SPOT
Another general disease prevalent in warm-season grasses is the dollar spot, and it has evolved to affect cool-season grasses as well. It is easy to identify this disease by small circular patches of light-colored grass. If ignored for too long, the patches will merge together, and you will witness a large affected area in your lawns.
Excessive watering and high humidity are two main reasons behind the emergence of dollar spots, and turf suppliers provide the following prevention tips.
PREVENTION TIPS:
- Water your lawn early in the day to allow the grass to dry before nightfall.
- Mow your lawn regularly
- Avoid cutting the grass too short
- Keep your lawn properly fertilised
