Expected weather for this month:

An unsettleld start to the month, but average temperatures throughout of 20°C

Key Tasks for June

Continue cutting regularly to ensure a good sward density. It may sometimes be helpful on newly established grass to lightly roll the surface before cutting to ensure that the plant does not get pulled out by the action of the mower. Also, ensure that any mowing equipment used is keenly set to cut without tearing.

June is when soils can dry out quickly. Make sure that your irrigation systems are functioning correctly as, once soils become hydrophobic and dry patch sets in, it becomes very difficult to get water back into the surface.

You may choose to use wetting agents to ensure uniform wetting, particularly on soils prone to dry patch.

Continue the work of brushing to keep the air circulating around the base of the plant, particularly important for removing early morning dew and controlling disease. However, suspend this operation for a period to allow for the germination of the new seedlings to take place, particularly on oversown thin areas.

Spike when the conditions allow, but keep your regime flexible. Surface spiking in a dry spell will help what rain you receive, or water you put on, to move quickly down through the profile to reach the new roots.

Now is a good time to thoroughly check your goalposts. Don’t just take them down and store them away. Make sure they will be fit for purpose for the new season.

Other areas should also be checked over, such as fences and dugouts.

 

General Nutrition

Consistently warm soil temperatures in June create ideal conditions for fertilisers with an organic component, whether that be straight organic fertilisers or organo-mineral. Organic sources of nutrition help to support the soil food web and manage the soil-plant system in a holistic fashion. Spring inputs of nitrogen aiming to get things going can be reduced and grass growth will naturally start to drop back as temperatures rise. In the wild, the plant would have now gone through its leafy growth spurt and be diverting energy into setting flower.

Calcium is a key driver of growth for roots and shoots, as it is responsible for the construction of cell walls. Calcium can become limited in dry soil, so ensuring soil levels are adequate and supplementing with foliar calcium helps it to maintain good health. Calcium, along with potassium, are essential for regulating stomatal function, helping the plant to better react to the onset of heat and water stress. Cold pressed liquid seaweeds contain plant hormones which also help to regulate against water stress and are a significant resource to be employed. Seaweed also contains hormones which promote germination and establishment.

Any areas which have been seeded in May will benefit greatly from the addition of seaweed. Carbon sugar sources and liquid humates will also drive establishment, promote soil biology and maximise the uptake efficiency of nutrition.

Water management

The use of wetting agents as part of a managed plan will pay dividends during June if hot weather occurs. Ideally, these should have started with the application of a block co-polymer in March at the latest, to give the soil a chance for the chemistry to accumulate in the soil. 

Penetrant wetting agents will help applied irrigation and rainfall to enter the profile from the surface down.

Regular sarrel tine aeration is a key cultural means of maintaining soil moisture levels as the shallow but tightly spaced tines puncture a large percentage of the surface area, allowing gas to escape from the soil and better aiding the percolation of water from the surface.

Growth regulators applied during periods of good growth in anticipation of hot dry weather to come will help the plant to conserve energy and manage water stress, again mitigating drought pressure. 

With respect to irrigation, a thorough soaking just before dusk gives the soil the maximum time to expel heat over night. Applying water at the end of a hot day creates a nice thermal blanket, trapping heat in the soil.

Little and often watering is appropriate for germinating seed and very young plants, but it is advantageous to thoroughly wet the profile and then let the soil dry down to just above wilting point if you can. This encourages the roots to penetrate and allows carbon dioxide to leave the soil and life-giving oxygen to enter.

Little and often watering also maintains surface humidity and will encourage algae, mould and fungi such a botrytis and Rhizoctonia spp. to attack swards.

Start thinking about your end of season renovations, and how you may be tackling the possibility of an extended season and the need to get onto the pitches to carry out the work. Start to build your strategy and get it down on paper. Look at what resources you will need - manpower, materials and machinery.

With reference to your machinery needs; if it's part of your inventory, drag it out, dust it off and fire it up to make sure it will work for you when you need it. If you don't have it in your inventory, but you know someone who has, a neighbouring club or school perhaps, particularly if you are on good terms with them; you may come to some arrangement to borrow it when they are not using it.

Alternatively, look at the option of hiring. There are a growing number of hire companies these days that are now specialising in the hire of sports ground equipment. With reference to your material needs, get them ordered now so that they are on hand when you need them.

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.
