Chafer Grubs

Chafer grubs are plump little grubs which live in the soil and feed on the roots of plants and grass from mid-spring through to mid-autumn.

If you see yellow or dead patches of lawn you may have chafer grubs. Where lawns are heavily infested, you may also see additional damage caused by foxes, badgers and birds ripping up the wilting turf to feed on the plump little grubs.

Our expert operatives can look at your lawn and advise on the best solution.

Leather Jacket

In the autumn you often see crane flies (daddy long legs) flying around and gathering near lights, at the same time your lawn could have yellowish brown patches and be covered in small round holes. This is a sign that your lawn has an infestation of leatherjackets. Pulling up a section of grass will reveal greyish brown grubs up to 30mm long with no legs or obvious head. Crows, magpies, rooks and starlings love to eat them hence the small holes in the grass.

Greengrass operatives will be happy to come and have a look at your lawn and determine the correct treatment to bring it back into full health.

Fusarium Patch / Snow Mould

This is one of the most damaging diseases found in lawns and is not easy to treat. Commonly known as snow mould, fusarium patch often forms in lawns when snow thaws and in prolonged very wet periods. The disease forms due to wet, humid climate conditions. When the disease first appears you could notice a small circle shape, like a tennis ball, in your grass in a creamy straw like colour.   Whilst the disease is actively growing the outer circle has a slimy texture, this can make the circles look like an irregular shape and some might say even look like clouds.

 

If you have Fusarium and it’s not treated during the winter and spring, it will survive the summer months lying dormant within the thatch in your lawn. Once the correct weather conditions arrive it will attack the living blades of grass within your lawn. It can spread quickly through lawnmowers, feet and any wheelbarrows etc.

 

Control of Fusarium

 

Non-chemical

  • Ensure that your lawn can drain quickly following snow or heavy rain by a combination of scarifying and hollow-tine aeration.
  • Remove overhanging trees or shrubs to improve airflow.
  • Remove heavy dews in the morning with a long pliable rod (switch) or a bamboo cane.
  • Ensure correct lawn feeds throughout the year.

 

Chemical control

This is best treated with a professional fungicide, Greengrass operative will advise you on this.

 

Fairy Rings

Fairy rings are circles of dead grass or circles of toadstools that spread out across the lawn usually in late summer and autumn. They are caused by colonies of the fungus Marasmius oeades, which lives in the roots of the turf.

Other types of fungi can cause fairy rings, but doesn’t have an effect on turf, and has been known to encourage growth of the grass! Symptoms vary depending upon the type of fungi that you have, however you may see the following symptoms within your lawn:

An irregular ring of dead grass that gradually expands across the lawn.

Directly across from the dead grass, the grass might be greener

Crops of brown toadstools at various times of the year.

 

Control of Fairy Rings

 

Non-chemical

These toadstools produce vast quantities of spores so there is no point in trying to remove them. In principle you can dig them out going at least 1ft beyond the ring, then reseed or returf.

 

Chemical control

 

This is best treated with a professional fungicide, Greengrass operative will advise you on this.

Red Thread

If you look at your lawn and see patches with a reddish or light brown tinge then this may be caused by a fungal growth known as Red Thread. This can be seen all the year round but is much more common in the autumn. Patches vary in size from 7.5cm (3”) to 25cm (10”) or larger. Close examination will show pinkish red gluey thread-like structures on the leaves.

Treatments

Non Chemical control

When you see Red Thread an application of nitrogen or iron can help to strengthen the leaves and this may be enough.

The problem of Red Thread can be reduced by good lawn care, improving the general condition of the lawn with aeration and scarification. Mechanical scarification removes thatch and moss resulting in improved air flow through the lawn.

Chemical Control

Severe cases of Red Thread will require the application of a fungicide. A Greengrass operative will visit your lawn on request and advise on the best treatment. Home gardeners can only use a fungicide (Trifloxystrobin – Provanto / Bayer Lawn Disease Control) applied a maximum of 2 times in a year. Professional lawn companies like Greengrass have other fungicides available to treat lawns complying with strict legislation.
