Performance Greenkeeping tasks for January

Here are some recommended Greenkeeping tasks for January maintenance work for the Performance Bowling Greens Programme.

Carrying out maintenance is of course dependent on the weather and underlying conditions. It’s important to keep an eye on the green as disease outbreaks can spread quickly when the weather turns mild again.

Here’s what you can be getting on with this month:

Mowing (8mm and at least one cut this month)

Mowing should go on through the winter months when conditions allow. It’s important to keep the height of cut at 8mm throughout the winter period and not to let the grass get too long at any point. Not only does longer grass encourage disease, by creating  a slightly warmer microclimate at the green surface, it also become coarser in texture.

Disease Control and Prevention (get some more Liquid Seaweed on)

Greens that are still in the recovery phase probably will see occasional outbreaks of fusarium when the weather is mild and you shouldn’t be too complacent about these if your green is still thatchy, annual meadow grass dominated and/or apt to stay wet and soft at the surface.

Spot treatments of fungicide are still recommended if needed.

Seaweed Liquid with its plethora of trace elements and natural plant inoculants is an essential helper in the soil in deep winter. Trace elements like Copper and Zinc are known to help grass plants fend off attacks from fusarium and other fungal pathogens and its bio-stimulant properties helps to keep the microbe population growing and active.

Dew/worm cast removal

Worm casts left on the surface or smeared into the turf with the mower become ideal seedbeds for weeds next year, so try to make sure you clear them using a switch or brush frequently when conditions allow.

We have over 20 species of earthworm and only 3 surface feeding species’ produce surface casts. They feed surface detritus, taking it back underground, helping to recycle it into soil. If you leave debris on the surface you will get more casting worms, so try to keep it clean.

Worm killers are mostly unavailable now thankfully, as they did more harm than good, so it comes down to suppressing worm activity if they are causing a nuisance. Light applications of sulphur pastilles (granules) can have a good suppressant effect.

Deep slit tining

This is the most important job throughout the winter months for any bowling green. By deep, I mean 125 to 150mm, with tines that can get in to the upper limit of this range being preferred.

If you’re starting this kind of maintenance for the first time, the tines might not penetrate to this depth due to hard, compacted layers in the soil, but persevere with twice a month slit tining and you will notice a gradual and incremental improvement in the depth achieved.

Bio-Stimulants and Microbes

If the weather is mild and the green is able to take a pass of the sprayer it’s a good time to get some soil rejuvenating bio-stimulants on your turf, and an easier route to adding microbes in winter is to pop 2 BioTabs in the sprayer with Liquid Seaweed or Defender.

Some very interesting research from Sweden here on how soil microbes don’t slack off in winter, so the more you can do to encourage a strong soil food web, the better.

Tank mix the Biotabs  with Liquid Seaweed for an additional bio-stimulant boost to keep plants healthy in stressful conditions.

Moss

Moss has been a continuing problem for many readers. Moss takes hold in any space that is left in the sward, so until your green has fully transitioned into a healthy, perennial dominated one, this will continue to be a problem, albeit decreasingly so.

Killing it at this time of year is of course counter productive as it simply creates space for more moss to come after it. If you still have lively looking moss on your green you can keep it under control until spring using some Liquid FeN or Chelated Liquid Iron

Looking forward to Spring

With the New Year well underway, many of you will have an eye on preparing for spring time work on the green. Why not make this the year you finally commit fully to achieving a Performance Bowling Green? The ebook that’s caused all the fuss is well under the price of a bag of fertiliser!…more here.

Soil Analysis with comprehensive report and ongoing support.

In addition to absorbing the message in Performance Bowling Greens, why not let me do a soil analysis for you. I’ll send you a kit to take the samples and also ask you some questions about the physical condition of your green, photos etc. Then I can write you a report with a suggested program for the spring start up and beyond. You can see the details of the soil analysis service here.

Questions Please

Of course as always, if you have any questions comments or problems, please feel free to drop me a line.
