June Golf Diary

blackwell-1jpg.jpg

By Laurence Gale

June is a very busy time for Greenkeepers with the longer daylight hours increasing the duration of golf play times, coupled with the start of many golf competitions which tends to increase the pressure on the greenkeeping staff to produce quality playing surfaces. Mowing and course preparation will be the priority, with the need to irrigate to keep the turf surfaces alive and growing, maintaining their colour and vigour. Mowing heights will now be down to the summer levels of 3-6mm, depending on the course and grass species being maintained.

Irrigation will now be a major consideration in maintaining turf surfaces. Evapotranspiration (ET) the combined water loss from both the plant and soil surfaces will now be rising due to the warmer weather. Watering will be essential for maintaining greens tees and fairways. When irrigating it is essential that you ensure the water is uniformly applied to prevent any dry patches forming.

Most of the tasks detailed can be undertaken within a limited budget. Local conditions and circumstances will need to be taken into account. If any members are undertaking any specific work not detailed, please let us know by adding a comment in the section below the diary.

June Maintenance Tasks for Golf Courses

Natural Grass

Task Frequency Reason
Aeration When conditions allow Greens. Generally from May through to September any aeration completed on greens is done with micro tines only so as not to disturb the playing surfaces.
Tees. Generally no aeration carried out on tees during June.
Fairways. Generally no aeration on fairways during June.
Amenity areas

Weekly

Tidy up any flower and shrub borders around the club house and entrance.
Brushing / Sweeping Daily / Weekly may-diary-cardenparkbrush.jpg Prior to mowing the surface should be thoroughly brushed. Continue to brush greens and tees daily to remove moisture from the grass surface, stopping the spread of disease and facilitating an improved quality of cut on the dry grass.
Bunkers Daily / weekly

Course Inspection Daily Inspect greens, tees, flags and hole positions for damage or vandalism.
Diseases including Moss & Algae Daily / Weekly Greens , Tees , Fairways. Keep an eye on fungal disease attack, and use approved fungicides to treat infected areas. With the recent spells of wet weather many golf courses are experiencing outbreaks of Fusarium particularly on their greens. Scarring of the playing surface is normally reduced as grass growth is usually dominant and vigorous in June, reducing the need to use fungicide treatments. However, there may be a need to apply a preventative fungicide treatment in the event of important competitions or matches, thus reducing the damage or effects of this disease.
Divoting As required Greens, Tees and Fairways. Repair any divots and scars.
Drainage Weekly Inspect drainage outfalls, channels and ditches. Ensure that they are working.
Fertiliser programme If grass shows signs of stress (weak growth, discoloured) Fertiliser treatment and turf tonic 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.

Most grounds staff will be applying their summer fertiliser's to maintain vigour and colour, aiming to cut back on the (N) nitrogen input and (P) phosphate elements, and apply something like a 8/0/6 NPK fertiliser. Generally USGA sand based greens tend to be more hungry for fertilisers compared to the pushed up soil greens. Most course managers would then look to colour up the greens with an application of iron and sea weed products prior to competitions and tournaments. Many course managers like to use straight compound fertilisers that act instantly to the conditions, rather than use slow release products that can initiate or stimulate growth when you don't want it.

The choice of materials and how well they work can be dependant on factors such as soil type and weather, with moisture and and air temperatures being the catalyst for growth.

Footpaths As required Keep all footpaths clean and free from debris, check any step details and hand rails ( Health & Safety).
Harrowing / raking When conditions allow Fairways. Harrowing/raking helps restore levels and keep surfaces open.
Hole Changing As required april-golf-diary-hole.jpg

Most golf courses are changing their hole positions at least three times a week.

Inspect Course structures As required The Course, Clubhouse, Car parks. Check and repair fences, seating, shelters, bridges, litter bins, shoe and ball cleaners, signs, and tee boxes.
Irrigation

Daily and weekly

Check and monitor all sprinkler head controls/valves to see that they are working, and check the spray patterns and timing of each and every sprinkler head. Also check any manual systems, hose pipes, sprinklers and pumps.

Soil and air temperatures during June are likely to increase affecting the rate of evapotranspiration ET (water loss from both the soil and grass plants) increasing the likelihood of the ground and surfaces drying out.

Its very important that irrigation is uniformly applied to keep the grass plant alive and healthy and to prevent dry patch occurring. Further information about Irrigation of sports surfaces can be see on link. Irrigation

Most golf courses often have formal garden/ornamental areas that require watering especially when new summer bedding schemes have been planted.

Litter / debris Daily / Weekly Greens , Tees and Fairways. Inspect and remove debris from playing surfaces. Litter, twigs and leaves. Regularly empty litter bins/tee boxes.
Machinery (Repairs & Maintenance) Daily / Weekly maydiary-carden-park-mach.jpg
Marking out Weekly Mark out trolley areas, out of bound site areas and range markings.
Materials Monthly Estimate and order seed, loams and fertilisers, fuels and other consumables.
Mowing As required June sees the mowing operations in full swing with the aim of reducing the height of cut of the greens, so that by the end of June the greens will be at their summer height (3-6mm). Other tasks that complement this work involve the use of grooming and verticutting units to remove unwanted thatch and side shoot growths. The frequency of grooming is fortnightly and verticutting monthly.

Mowing frequencies varying from daily to twice weekly operations dependant on the growth of the grass and the standards set by the course manager. Mowing heights may vary depending on local conditions, type of course, course expectations, sward type and mower type. The mowing heights are a guide, and will be subject to local weather conditions, but remember not to remove more than 1/3 of total grass height in each cut. The less stress that is placed on the grass at this vital time the better the results further on into the season.

Greens. Mowing height should be maintained at around 3-6mm.
Tees. Mowing height should be maintained at around 10-15mm.
Fairways. Mowing height should be maintained at around 15-20mm.
Rough, Semi rough grass areas. Mow and tidy up these areas.
Pest control As required Weed growth is very active during June enabling course managers the opportunity to use and apply selective herbicides. These are more effective when the plant is actively promoting growth.

Moles and rabbit damage; repairs as required.

Ponds, lakes and streams Weekly may-diary-carden-park-strea.jpg
Seed bare & worn areas When conditions allow Greens, Tees and Fairways. Over seeding of sparse or bare areas can be continued, the rise in temperature will help germination. Use germination sheets to aid this process but remove the sheets regularly to check for diseases. Remember that without good seed to soil contact the operation is useless.

Ensure you use new seed as old material may not give you the required germination rates. Remember, bents and fescue grasses require higher soil temperatures for successful germination. You may need to wait for favourable temperatures later in the year.

Tee boxes, pegs As required All tee boxes, tee pegs and competition markers should be inspected daily, cleaned and moved to new positions as required.
Top dressing As required Greens & Tees. Ensure you have enough top dressing material for any renovation or repair works carried out in June.
Wetting agents As required If wetting agents are being used they are generally applied monthly throughout the season.
Woodland & conservation areas. As required april-golf-diaryashridge-Ot.jpg
Artificial Tees and Mats
Artificial Grass Systems Weekly Keep surface clean, regular sweeping and brushing. Remove any algae and moss from surface.

Sand filled systems require regular brushing to maintain manufacturer's recommendations for sand levels and pile heights.

Rubber Tee Mats As required Keep clean.
