Key Tasks for September
End of Season Renovations
September marks the beginning of autumn and, for the wild grass plant, a time for May’s flush of growth, June’s fluorescence of flowering and July’s efforts of ripening to bear fruit; as the seeds dropped onto the ground in August take maximum advantage of the available warmth and adequate moisture in the soil to germinate, develop and grow. This is a process nature has set in place to afford young seedlings of the next generation the opportunity to establish a foundation, such that they can overwinter and then spring forwards as temperatures return the following year.
It is now that the turf manager mimics nature’s perfect blueprint, as across many surfaces we set about renovating at the end of the growing season.
Seed sown with good contact to the soil will be able to draw up moisture and use the residual temperature to establish. Applications of growth regulators, shortly prior to the operation, can assist in holding back competition from the mature plants already in situ.
Adequate nutrition is as important as ever. An application of energy from phosphorous helps to synthesise ATP, the energy currency of all cells. Calcium will provide the raw ingredients to drive cellular generation at the growing tips of roots and within new leaves. Additionally, it will strengthen the primary cell wall, strengthening defences against pathogenic fungal attack, particularly as cooler nights coincide with warm days to produce heavy dews.
Avoid heavy applications of nitrogen on fine turf surfaces in particular. Avoid also inputs designed to stimulate biological activity.
A productive soil ecosystem is a core fundamental of a healthy rootzone and, in turn, grass plant. That said, a soil-plant ecosystem which is too productive during the autumn can lead to an excess of nitrate nitrogen, leading to soft growth more susceptible to fungal diseases.
The Emergency Authorisation for Acelepryn ends on the 30th of September. Application of the product when adult Chafers are monitored as being on the wing means that all those eligible to apply the substance should now have done so. Monitoring should however continue. Lift areas suspected of being infested and check for both the presence of live grubs as well and dead ones. Where chemical control is not authorized, Entomopahogenic nematodes can be applied throughout the month. Warm soil temperatures and available moisture are conditions which play nicely into the hands of Entomopahogenic nematodes who swim in the water film on soil particles in their bid to search out a larval host.
Worms will also take advantage of the morning dews with casting becoming a problem on many areas. There are no legal controls for earthworms and anything applied which directly affects or deters them is done so illegally.
The responsible course of action is cultural management via a combination of localised surface acidification, removal of grass clippings to reduce their food source and sanding of surfaces to assist in the drying out and dispersal of casts.

Maintaining a cricket square requires regular mowing, so it is important to keep your blades sharp at all times. Backlapping will help prolong their lives, but they should be sent for re-grinding, with your bottom blade replaced at the same time, especially a shaver blade.
Check your ground for foreign objects, such as studs or stones which can cause considerable damage to machinery and pitch.
Grounds Training was established in 2006 to provide a complete and unique service delivery training courses for the sports turf industry. We are now the go-to provider for on-site, bespoke training for groups. Alongside our renowned turf maintenance which now includes Lantra accredited Online courses. Grounds Training also works with the industry’s awarding bodies – Lantra and City & Guilds (NPTC).
Open courses for individuals to join are also offered at our Allscott (Telford) Training Centre, Most courses lead to Lantra Awards or NPTC qualifications; a small number of niche courses where the instructor is an experienced groundsman who is also Lantra Awards or NPTC registered, offer Pitchcare certification.
Whether your staff are involved with preparing and maintaining sports turf, operating ground care machinery and equipment or require a safe use of pesticides qualification, we have the course to suit them.
