In addition to regular scheduled maintenance, the lawn may occasionally require emergency repairs, e.g. due to lawn diseases, mosses and various pests, chemical or sunburn.It is worth noting that with proper comprehensive care, such problems become rare.
The most important thing in emergency lawn cover restoration is to notice the symptoms in time, correctly diagnose the problem and choose the right course of action for repair, restoration of the lawn and prevention of possible recurrences. As we know, if the patient does not receive the right course of treatment, disease will progress, so we advise you to seek emergency help from your area only from a proven specialist.
Common lawn diseases
Lawn grass is most susceptible to fungal diseases – various types of mold. The main signal of fungus is the presence of baldness and spots of different colours, white, grey, yellow, reddish-brown.
The main reasons for the development of mold are constantly overmoistened soil, lack of certain minerals or, conversely, its overabundance, the presence of vegetable felt on the lawn, prone to rot, as well as insufficient aeration or exhaustion of the soil.
In the case of mould, the lawn is treated with fungicides and regenerated by removing the turf layer and sowing new grasses. After that, it is important to eliminate the cause of the disease – to normalize the humidity, adjust the fertilizer complex or take drastic measures in particularly severe cases, for example, to remake the drainage system – a popular cause of excessive humidity.
Common fungal lawn diseases and their symptoms:
- The so-called “red thread” is caused by the fungus Laeti-saria fuciformis, looks kike brown spots which then go pink. If you take a closer look, you can see the red threads of the fungus on the leaves. Reasons for this are high humidity or lack of fertiliser.
- “Rusty mold” is caused by the Puccinia fungus, which forms round spots of rusty colour. The fungus dries the plant out and it dies. The disease is caused by soil exhaustion, sudden temperature changes, plant residues on the lawn and poor lighting.
- Dollar spot disease affects parterre lawns due to a lack of nutrients, too frequent mowing and too much of a felt, and is characterized by brown and white spots with the size of a silver dollar.
- Fusariasis (fungus Microdochium nivale), a common “snow mold”, most often appears in spring in the form of yellowish dry spots, which grow and are covered with white fluffy mold in wet weather. You can stimulate the development of fusariasis if you do not pay attention to aeration and felt removal.
- Ofiobiosis (fungus Gaeumannomyces graminis) affects the whole plant, its stems and roots, causing the grass to dry out and die. It is caused by disturbed gas exchange and increased soil ph levels in the form of dark green and then brown spots.
Algae, mosses and lichens.
Lawn diseases as mosses, lichens or algae may appear on areas with heavy clay soils in rainy, cloudy summers. Water stagnation on the lawn, untimely removal of plant felts, poor aeration and too little mowing also create a favourable environment for the growth of these plants.
How do you control such weeds?
First of all, treat the affected areas with dichlorophen or general herbicides, remove dead mosses and sow the resulting glades. It is very important to overcome the very cause of the infection and prevent relapse. Sow more shade tolerant grass varieties, improve drainage system, regularly ventilate the soil.
Among the common prevention methods for soils with a high level of acidity are lime treatment, spraying with copper or iron sulfate and ash fertilization.
Moles, insects and… pets
After a lot of effort has been put into organizing fertile for a beautiful, healthy lawn, its owner may face a new problem – the growth of grass attracts unwanted residents – mole and insects digging holes in your land.
Moles can leave a dozen heaps of soil on your lawn overnight, instantly spoiling its appearance. How do you fight them? Unfortunately, military methods are to set traps and lay out poisons. In some cases, you can get sonic repellent devices. And, of course, it is necessary to fix burrows, to compact the soil, to sow new lawns right away.
In the case of ants and bees damage will not be so global, it is enough to periodically treat their nests and routes with drugs, controlling the insect population and preventing them from invading.
Unfortunately, our favorite pets – cats and dogs – can also act as lawn pests. Their faeces and urine are saturated with active substances that literally burn out the grass and leave yellow dry spots on the lawn. If it is not possible to wean the animal from using the area as a toilet, the only obvious solution is to repair the affected areas periodically. Alternatively, your favourite lawn spots can be replaced with paving stones.
Yellow dried out stains of grass can be not only a sign of illness, but also a consequence of overdose or improper fertilization, as well as sunburn. The fertiliser should be applied carefully to the surface of the soil, preventing pellets from getting onto the leaves. In order to avoid sunburn, the correct watering regime should be followed, avoiding daytime irrigation, and the composition of the grass mixture can be adjusted towards more sun-resistant varieties.
In most cases, lawn diseases and other problems that require emergency repairs are caused by improper or insufficient care. As in the case of human health, in addition to treating symptoms, it is also necessary to eliminate the cause of the disease and prevent future diseases, i.e. to strengthen immunity. How to strengthen the immunity of the lawn? To make it stable and full of strength. Monitor the soil, regularly feed, water, strengthen the root system. This will make the lawn resilient to stress and environmental influences, eliminating the need for emergency lawn rehabilitation in the future. Hoped you learned to restore lawn from lawn diseases
