June Bowls Diary
By Laurence Gale MSc
June continues to be a busy month for bowls, with the long daylight hours resulting in many evening matches being played.
The maintenance regime continues with regular mowing, grooming, feeding, brushing and watering ongoing. With the likelihood of drier warmer weather irrigation systems may be called in to use to maintain the water requirements for the green. Allowing the green to dry out can lead to a condition called dry patch which, in time, will lead to inconsistent surface playability.
Check areas where dew is not present for signs of stress or dry patch. These areas may need hand watering and the green as a whole may benefit from the application of a wetting agent. If this is the case treat these prone areas with a sarrel roller prior to using the wetting agent and monitor closely.
Generally with the long hot days, irrigation will be important, but better to give the green a good dousing every two or three days than a little bit every day. This encourages roots to strengthen and go in search of water.
It is essential to ensure there is enough soil moisture present to activate the fertiliser product used. Liquid feeds are more efficient in getting into the plant especially when used as a foliar feed.
Applying a balanced fertiliser regime will help prevent the plant becoming stressed, especially during drought conditions. The aim is to keep the roots growing. The well-being of the grass plant is influenced by the state and condition of the roots. Most of the plants nutrient requirements are taken in by the rooting structure.
Seeding sparse or bare areas can be continued. Any rise in soil or air temperatures 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.
It is important that you use a compatible rootzone material for any repairs. These may come in different formulations, generally a 70/30 sand soil mix is the one used by most groundstaff, who usually mix their grass seed into this rootzone medium prior to spreading and integrating into the worn areas.
Ensure you use new seed as old material may not give you the required germination rates.
Top dressing is usually carried out in spring and autumn in conjunction with the renovation programmes. However, some bowling clubs have a policy of applying top dressing materials during the season. It is important an appropriate top dressing material is sourced to ensure compatibility with the existing rootzone materials of your green. The last thing you want to encourage are rootbreaks in the green.
Spreading of the materials can be achieved by several methods, utilising pedestrian or ride on disc or drop action top spreaders, or by hand using a shovel and a barrow. It is important to get an even spread of material, the aim is to put on a very light dressing, followed by brushing in with a lute or drag brush/mat to restore levels.
Double cut the green in diamond formation for tournaments and finals. This type of cut removes more grass from the same area without the need to reduce the cutting height. Most bowling greens tend to suffer dry patches at the edges of the green, generally caused by mowing practices, where you continue to turn. The use of turning boards can help reduce wear on these areas.
Check grass in times of heat stress, roll instead of cutting once in a while to ease pressure. If temperatures remain high it may well be necessary to syringe the sward with water to cool surface temperatures.
Monitor for disease or pests, prevention is better than cure.
Check and inspect ditches, floodlights, structures and any site furniture for damage, keep the site clean and tidy and maintain a tidy appearance throughout the facility.
