November Rugby Diary 2010

Laurence Gale MScin Rugby

November can often be a challenging month, contending with a changing weather front, cooler air temperatures, frost snow and heavy periods of rain. The demands on the pitches remain the same while the day length for doing the work is shorter with the clocks going back. Many clubs also organise bonfire events, which often leads to a lot of work for groundstaff, who are usually responsible for building the bonfire and clearing up afterwards.

Playing surfaces are more prone to damage in the winter months when ground conditions tend to remain in a wet state, also the onset of frosty weather can affect maintenance regimes. Playing on frosted and flooded pitches will only cause damage to the playing surface. Allow for the frosts to clear and allow time for the saturated pitches to drain before use, or indeed using equipment on the pitch.

You will soon lose grass cover if you play on wet playing surfaces. Grass growth is slowing down due to the low soil and air temperatures. Grass struggles to grow when temperatures drop down below 5 Degrees C. and recovery after damage is limited.

Early in the Month 1st - 15th November

Keep up your weekly routines of pre and post match maintenance - mowing, marking out, divot replacement and brushing. Presentation of the pitch is important. Use string lines to help keep straight lines and mowing bands.

It will be a good practice if you have the time to brush / knock off any heavy early morning dews that form on the playing surfaces; this will help reduce the incidence of disease.

Later in the Month 16th November - onwards

Keep a check on pitch equipment, flags, post protectors and ensure they are fit for purpose. Remember to keep a good supply of marking materials and keep the marker clean after use.

Key Tasks for November

RFU guidelines stipulate that the accepted heights of cut during the winter months should be maintained at between 30mm to 90mm.

Many junior club pitches tend to have too much grass on their pitches. I regularly see rugby pitches that are not cut on a regular basis and the grass length often exceeds 125mm - far too long, thus it becomes weak, straggly and often flattened after play or training.

Most senior clubs now maintain their pitches between 30-40mm, giving them a faster surface to play on.

Ensure your mowers have sharp, well-adjusted blades and that there are no oil leaks.

Facts about mowing

If grass shows signs of stress (weak growth, discoloured), fertiliser treatment and turf tonics can be continued in accordance with your annual programme. If you haven't got a fertiliser programme, have your soil tested; try an independent soil analysis company for an impartial set of results.

Generally, few fertiliser applications are made during the winter months, as plant growth has slowed down. However, some groundstaff may apply a dose of liquid iron to colour up and provide some strength to the grass plant during the winter months.

Pitch Presentation

The presentation of the pitch is important. If it looks tidy and well presented with bands and stripes it often inspires the players to perform and, more importantly, gives them a safe, consistent surface.

Soil based pitches, generally the heavy clay and clay loam ones, will be susceptible to surface damage during wet weather, especially when the top 100mm becomes saturated.

Soils, when saturated, lose their stability and strength. Damage from scrummage and line out play are the main causes of damage on rugby pitches during wet weather periods. The severity of the damage will be dependent on the soil type and the ability of the top 100mm to drain quickly.

To help keep the top 100mm free draining, a programme of surface aeration is necessary. This is achieved by regular spiking with solid/slit tines to a depth of 150mm or more when conditions allow.

There are other specialist machines that can help with improving surface drainage, for example the Blec Ground breaker and the versatile vertidrain machines that are now available. In recent years, we have seen the introduction of linear aerators, machines that cut a slot through the soil profile, usually at 200mm centres.

Hand or machine aeration to aid surface drainage, varying depths of penetration to prevent the development of a soil pan. As last month, if there is opportunity to aerate, then do it. Regular autumn aeration provides air space for the roots to expand into and the plant to breathe. Achieving an improved root system will stand you in good stead for the coming winter months.

Inspect drainage outfalls, channels and ditches. Ensure that they are working.

Pitch Disease July 09 003.jpg

Diseases can still be prevalent in November due to the cool, wet ground conditions, and particularly with heavy dews on the playing surfaces. It is important that groundstaff remove these dews to prevent disease attack. Many stadium clubs are experiencing outbreaks of leaf spot and red thread. A dose of approved chemical fungicide will help control and prevent the spread of these diseases.

A wetting agent is sometimes used with the fungicide to help it penetrates deep enough into the soil profile. With the sun now lower in the sky, shade problems in stadium environments tend to be increased. The sun tends to cast longer shadows that often remain on the ground for long periods. Shaded areas tend to take longer to warm up and dry out, which in turn may affect maintenance operations and playability.

Brush or sweep daily to remove dew and remove surface debris. Using a brush or a SISIS quadraplay will restore levels and produce striping or banding aesthetics.

Keep and eye on fungal disease attack, and use approved fungicides to treat infected areas. Early morning dew on playing surfaces often promotes the chance of disease attack. Regular brushing off the dew will help prevent an attack of turf disease.

Other Tasks for the Month
  • Drainage / Weekly / Inspect drainage outfalls, channels and ditches. Ensure that they are working.

  • Goal posts / Weekly / Inspect goal posts and sockets to check they are safe and secure.

  • Grooming/ verticutting / As required / Grooming and verticutting are operations that remove unwanted side growth and reduce the amount of debris in the sward. These operations are completed in conjunction with your mowing regimes. Brushing the pitch in the opposite direction prior to cut will produce a cleaner finish and a healthier sward when used in partnership with verti-cutting.

  • Harrowing/raking / When conditions allow / Helps to restore levels and keep surfaces open

  • Earthworm activity usually increases in November. Earthworms can survive in a wide range of conditions, but most earthworm activity is dependent on the quality of food available. Worms like plenty of Organic Matter (OM), therefore greens with a high thatch problem tend to encourage worm activity. Soil pH also affects where earthworms are found. In strongly acid or alkaline soils earthworms are rarely seen (pH less than 4.5 or greater than 8). The soil texture will also affect the number of earthworms found; they prefer clay soils and are less frequently found in sandy soils.

  • Worm activity inevitability leads to worm casts appearing on the playing surface. These worm casts can be very problematic; casts tend to smear the surface, which in turn can affect surface water drainage capacity as well as providing a seed bed for weed germination.

  • Leaf clearance will also be a priority. Wet leaves left on playing surfaces will eventually cause problems, they will affect line marking and, if left on the surface for too long, will cause the turf to become yellow and even begin to die. The use of blowers and sweepers will help keep surfaces clean.
