44 MAINTENANCE CALENDAR Remedial jobs – complete extra jobs such as painting the posts and ensuring all edges are cut neatly. Also, keep an eye on machinery using your daily and weekly checks and if any servicing is required. Rugby Union The season is about to get underway so the pitch should be getting to somewhere like its best for the beginning of the season. Mow at 30 mm every day plus a once weekly cut at 25 mm to remove annual meadow grass seed heads. Aeration – vertidrain bi-weekly down to a maximum depth of 12 inches with 4 inch spacings. Fertilise generally with 12+0+9 or a 20+10+10 if a flush of growth is needed, 12 x 25 kgs. Brush every morning to help stand the grass up and eliminate morning dew. Repairs – walk over and divot every day. Spraying – an application of wetting agent plus liquid fertiliser. Mark out once a week, once the first session on the pitch is required. Irrigate as often as possible as time constraints and training times allow – higher temperatures means more water.

Tennis Now is typically the time that a fertiliser with a lower percentage of nitrogen is applied, especially on more lightly used courts. Continue with routine maintenance, which will include mowing, grooming, brushing, irrigation and overmarking. Where there are multiple tennis courts on site, try and take some out of use and renovate them prior to September. All the materials that are required for the renovation programme should be in stock or at least planned for delivery. Regular mowing of tees, greens and fairways as well as irrigation will be the major tasks for this month. Bunker raking on a regular basis, if not daily, will also help to put the finishing touches to a well-presented course. Horse racecourse Routine maintenance work over the summer months will include the following: Artificial/specific use of irrigation will be more frequent to produce a suitable firmness of ground for a race meeting. Continue to divot and repair after each meeting. Continue to mow regularly, with this forming a significant part of total work input. Do not neglect mowing on courses that are rested over the summer. A fertiliser application in late August might also be given to all, or part of, the course this dependent on need and following a nutrient analysis. Golf course A fertiliser application on the greens will most likely be given during this month. Typically one would be an 8:0:0 @ 34 g/m2 Nitrogen only. While renovation will mostly be undertaken in September, a gradual process of renovation can start now. The extent of the work will depend on important competitions/matches, but operations such as micro-solid-tining, with 6 mm diameter tines, should be considered. This results in a minimally affected playing surface for only a short period of time. If some form of renovation work is not to be done on the greens, then tees or fairways should be targeted. Make use of this month to do some renovation because after September the soil and air temperatures drop rapidly. Fusarium can be a problem now that the nights are drawing in and dew is more prevalent in the cooler mornings. This should be controlled using a proprietary fungicide to prevent widespread damage to the green. When carrying out topdressing, ideally undertake a survey of the green beforehand to give an indication of the levels. The identified low areas can then be topdressed with more material than any high spots, which may not require any dressing. This will help in the production of a flat bowling green for next year. Make observations on crane fly activity as this will indicate the potential level of control that may be needed in October/November to eliminate leatherjacket grubs. Whatever else happens, make sure you get on with the renovation process as quickly as possible. Cricket square With the season now closing, or closed, a thorough renovation of the square will be required. Mow the whole square to 5 mm or so, to produce a fairly clean top surface. the Groundsman August 2012 SEPTEMBER Bowling greens While the season will not be completed until the end of the month, or even the beginning of October, some of the end-of-season renovation can be carried out now, especially after all the competition finals have been completed sometime during the middle of the month. Hollow-tining a green can be readily carried out within a day using a suitable machine which may be designed to collect the cores or staff may be used to brush, rake and shovel up the cores as soon as the machine starts working. If the cores are dry, a litter blower vac can be used to blow most of the cores into defined areas of the green making it easier to remove them. Once the hollow-tining and clearing up has been completed, the green should be cut to provide a satisfactory playing surface. This hollow-tine operation can also be carried out a second time, at the end of the playing season, if needed.
