Key Tasks for November
End of season renovations should be completed, therefore, during November, the following activities are usually undertaken:
- Maintain a winter height cut of 10-12mm
- Carry out inspection and maintenance of machinery and irrigation equipment
- Service equipment and replace any worn or damaged parts.
- Check for diseases and pests, seek advice if necessary
- Aerate when conditions allow
- Clean up any leaf debris
- Drag brush daily
- Spike, if and when possible, and only if conditions are right
- Maintenance of fences and hedges
A generally mild October with good growing conditions has provided opportunity for continued recovery across many areas of the country, especially in the north and west of the British isles. Speaking to turf managers across the south and east, comparably lower rainfall in some areas has resulted in stalled recovery from summer drought stress. Maximising any rainfall via the use of penetrant wetting agents and aeration will assist the rehydration process; something which needs to be encouraged before cold temperatures eliminate opportunities for growth.
With that in mind, the forecast for November is for periods of stormy and wet weather interspersed with drier spells and crucially, with respects to turf management, below average temperatures.
As always then, prior preparation with a mindset to wards proactively making use of favourable windows are key considerations.
TURF DISEASE TRIANGLE
Disease incidence can be correlated with the factors in the disease triangle. All three factors are required to coincide for an outbreak of disease. The major pathogen on turf surfaces throughout November will be Microdochium nivale.
Consideration of the contributing factors
- Susceptible host – excess leaf growth and stress will lead to the grass plant (host) becoming more susceptible to fungal pathogens. The key phrase here is appropriate nutrition. In practice this means the Goldilocks zone of nitrogen, just enough to keep the plant healthy but not too much to cause a flush of soft growth which allows the disease to attack more successfully.
Providing the plant with calcium, silicon and phosphite strengthens the cell walls and helps the plant to resist attack without resorting to chemicals. Applying plant beneficial biostimulants such as seaweed and carbon energy when conditions favour the plant primes its metabolic defence responses and assist’s beneficial microorganism’s to help repel the disease.
- Virulent pathogen – Is the pathogen being provided with the resources it needs to thrive? In the case of fungal pathogens this would be prolonged periods of leaf blade wetness and nutrition. Manage this situation by removing dews, reducing humidity within the thatch layer via aeration and the application of penetrant wetting agents. Also avoid applying biostimulants such as seaweed and carbon energy at times when the pathogenic activity is actively on the rise.
- Favourable Environment – prolonged humidity as a result of overcast days and nights, rainfall, cool temperatures which slow grass growth and low wind speeds which extend drying times are the factors which when they align drive the arms race between host and pathogen away from the grass plant and towards the disease. Monitoring forecasts and historic patterns facilitates prediction of high disease pressure. Allowing turf managers to act appropriately.
Nutritional requirements will be aligned with growth, put simply the more growth the more nutrition required. Typically fertilisers applied during renovation operations should see the majority of surfaces through November and into December. As a result NPK applications will be limited however, targeted application of secondary macronutrients and micronutrients to elicit plant responses such as those outlined above with calcium will bring tangible benefits.
Maintaining appropriate water air ration is a key factor in reducing turf stress during periods of the year where rainfall increases and drying opportunities are reduced. Little and often aeration via methods such as star tineing and sarel rolling facilitate diffusion of oxygen into the profile and carbon dioxide out. This allows the plant roots and beneficial soil microorganisms to breath which reduces plant stress and sustains their population numbers respectively.
Maintaining water percolation into deeper aeration channels and drainage systems via the application of penetrant wetting agents reduces the tendency of water to be held at the surface where it acts as a barrier to gas exchange and increases localised relative humidity. Something which helps fungal diseases to grow and spread.
Regular applications of products containing sulphur will acidify the local soil surface environment and discourage worms from casting. Avoid regular products containing iron which is not in a liquid chelated form as this will quickly oxidize and build up in the soil chemistry causing numerous problems such as reduced pH, iron panning, nutrient lock up and inhibition of microorganisms.
It is important to maintain machines by carrying out regular servicing and repairs.
As grass growth slows down, use the time to take some machines out of operation for an overhaul.
- Keep machines overhauled and clean
- Maintain a stock of consumables for your machinery, replace worn and damaged parts as necessary.
- Keep an eye on your material stocks (seed, topdressing, petrol, oil), remembering to replenish as required.
- Service machinery and equipment - changing oil / air filters and greasing up moving parts and sharpening mower blades.
We are pleased to announce the launch of our new Grounds Training website, together with our new suite of Online Courses.
Our Lantra Accredited Bowls Green Maintenance Course is now available as an online course.
Now you can learn about maintaining a bowls green in the comfort of your own home and in your own time. This newly developed course consists of a number of videos with assessment questions, and an accompanying hard copy Course Manual. The Online Course is Lantra accredited and provides you with all the basic knowledge required to maintain a green over a 12 month period. There is also the option of attending a one day practical course.
Pitchcare is the only provider of LANTRA accredited training courses in the maintenance of Bowls Greens.
We can also arrange Lantra accredited training on site to groups of 6 – 10 people. Email Carol Smith for information.
The Course Manual is available for purchase separately.
At this time of the year, when the weather allows, a general tidy-up of areas around the green makes all the difference; this would include tasks such as hedge cutting, clearing ditches, painting club house, weeding paths and borders.
Check and inspect ditches, floodlights, structures and any site furniture for damage; keep the site clean and maintain a tidy appearance throughout the facility.
