February Tennis Diary 2012

February can be a very unpredictable month regarding the weather, temperatures tend to fluctuate and you may even get more snow and frost depending on which part of the country you are in; also, you may get some strong winds that will dry your surfaces out quickly.

However, we have just be having a relative mild weather period with soil and air temperatures well into double figures in some parts of the country , which has stimulated some grass growth. If ground conditions allow, you may be able to get your rotary mowers out and tidy up the grass courts; rotary mowing grass surfaces in the winter months has become a popular way of keeping playing surfaces neat and tidy.

If however you have been unlucky with the weather and had snow cover for some days, there is a likelihood you may be get caught out with some outbreaks of disease.

It is important, after a period of snow cover, to be on the lookout for any turf grass diseases, particularly Fusarium and snow mould. The change in temperatures and the fact that snow cover can act as an incubator are often the catalyst for disease outbreaks.

Diseases may still be prevalent, especially after a period of snow or changing weather. Continue to keep the sward dry by regular brushing/caning the dew off the courts in the mornings. Preventative fungicide spraying may be necessary to control these diseases.

It often pays to use a selection of these products over time, rather than constantly using the same product year after year, as the disease can become resistant to the formulation, if continually used.

Ideally, Integrated Pest Management (IPM) strategies should be employed to deter disease attack in turf. IPM is all about putting into place good working practices that reduce and prevent the conditions that support and initiate turf diseases; and integrating a number of cultural practices that can break up the disease cycle and promote healthy, more vigorous growing turf, which in turn promotes a healthy sward than can be more resistant to disease attack.

Beneficial cultural practices are:-

* Brushing and switching to remove early dews off playing surfaces.

* Programmes of aeration/spiking to help reduce anaerobic conditions.

* Machines are well serviced and sharp; poor grass cutting results in leaf tissue damage that provides a good entry point for disease pathogens.

* Effective feeding programmes to keep the plant strong and healthy, so it can resist any disease attacks.

Whilst, the soil profile often remains quite cold and wet in February, it's best to keep off the courts, you do not want to risk damaging the surface as grass growth recovery is virtually non existent during these conditions. However, when the surface becomes drier, the opportunity to spike/aerate in February will be of some benefit.

With regard to aeration practices, any deep aeration of the courts should have been completed in January, so as not to incur problems later in the year. Deep aeration carried out in late February or March can lead to the tine holes/slits remaining in the soil profile well into the playing season, which can cause some surface deterioration when the clay soils begin to dry out.

Sarrel rollers can still be used to keep the top 20-45mm open to aid surface water drainage.

There may still be some bare or thin sward areas; these can be oversown when weather conditions improve; the use of germination sheets will greatly improve success rates.

Mowing heights: the sward should be maintained at its winter height of cut between 12-18mm. The use of a rotary mower can be ideal for topping off and, at the same time, cleaning up any surface debris.

Artifical surfaces: Artificial tennis surfaces also need attention. Regular brushing is essential to keep them clean and free from contaminations. Sand filled/dressed carpet systems also require regular brushing to keep them clean and to redistribute sand infill materials.

American Fast Dry courts: Keep surface clean, rolling to consolidate surface, levelling and brushing of fast dry materials, brushing to clean lines.

Tarmac Courts: February is a good time to clean your tarmacadam playing surfaces. Ideally, it pays to power wash the courts surface to remove any debris, moss and algae that will have accumulated and deposited itself on the courts during the winter months. Be careful when washing, using a too powerful washer can result in surface damage.

Keep surfaces clean, regular sweeping and brushing. Repair any hollows or damaged areas. Repaint lines.

Moss and algae can be a serious problem on tarmac tennis courts, especially if the courts are situated next to trees and hedges, the shading and damp conditions create a favourable environment for moss and algae to grow.

Regular brushing and cleaning of the courts helps disturb the moss preventing it from taking hold. However, once established, the best methods of control are by a combination of chemical and washing activities.

Clay courts: Keep surface clean, regular sweeping and brushing to restore playing levels using SISIS Trulute or similar equipment. Topdress any hollows or damaged areas. Repaint lines.

Algae can often be a problem at this time of the year on artificial playing surfaces. Regular brushing and fungicide treatments may be required to reduce and remove algae growth on the courts. You should use approved chemical products when treating algae problems.
