Bowls Green Maintenance and elephants

In the early part of the season no growth means no recovery from last winter’s damage, bare areas not filling in with new grass, bumps, hollows and all sorts of other problems mostly related to surface smoothness and consistency.

I’ve heard more than my fair share of strange reasons in bowling green maintenance circles when there is a lack of growth. These mostly centre on almost every bowling green maintenance practice except the one that matters…why?

Well the one that matters is “Irrigation” and it’s still a big taboo in a lot of clubs and in bowling green maintenance circles; it’s “the elephant in the room” to use one of the most annoying buzz phrases in recent times! However the elephant in the room description is a good one in this case; it’s this big, obvious thing in the room or in the conversation, but nobody mentions it!

One club I met with told me they have an “anti-watering brigade” in their club! Can you believe that, a group of members who are actively against watering the green regardless of how much it needs it?

On a well known bowling forum which shall remain nameless here, a contributor added his tuppence to the discussion on irrigation by “boasting” that they never water their green, as if it was some impressive badge to be worn. Another says that watering 3 times a day is crazy (as suggested by another contributor), even though he has no information to tell him the quantity of water being applied or thinking behind the plan.

We really must get over this folks or there will be a lot of very poor bowling green surfaces next year.

Bowls Green Maintenance Basics-Green Speed

There are some less than obvious essentials required to achieve consistently agreeable Green Speed

The great debate about green speed has raged on since the beginning of the game. But what are the factors known to affect green speed?

In order of their impact on green speed these are the top 7 factors that you should bear in mind. Obviously there are others such as weather patterns, level of play etc, but these are largely out of the greenkeepers control and in any case do not figure highly in green speed management.

Thatch Layer Control and Management; this means knowing the thatch levels on your green and having a feel for how quickly thatch builds up at each point in the year.

Typically thatch will be much quicker to build up in the main growing season and it can easily take greenkeepers by surprise if they don’t keep a watchful eye on the situation.

Reducing a troublesome thatch layer significantly is a job best left for the autumn when severe measures can more safely be taken, but following the Performance Greens program will ensure that you are minimising the occurrence of new thatch through the production and maintenance of a healthy living rootzone and turf.

Localised Dry Patch still causing problems in autumn

Localised Dry Patch causing seed problems

Over-seeding of bowling greens seems like a straight-forward task; you put the seed on and the green’s bare areas recover.

However, one of our regular readers has raised an interesting question today about over-seeding and it is by no means isolated.

After over-seeding the green, the seed has taken well on the parts of the green that least needed it and nothing has happened on the barest areas of the green where the new grass is most needed!

This is unfortunately a very common problem and is usually related to our old friend Localised Dry Patch (LDP).

The barest areas of the green going into the autumn are usually the spots that have been affected by LDP and as such are bare due to lack of soil moisture.

This means that quite a lot of preparation is required before seeding and this might even include heavy watering to get the soil to hold enough moisture to get the seed off to a good start.

It might be necessary to do some light cultivation with a Sarrell roller or hand cultivator and, if the underlying soil is still dry and water repellent, a wetting agent would also help.

The main problem is that we are now a bit late for further seeding, although this largely depends on the weather and temperature. I have seeded successfully up to Christmas in the past, but success with this is obviously dependent on the remainder of the winter. Certainly if we were to get another one like last year, even early seedings will struggle to survive the winter.

If anybody is still having trouble getting grass cover on the green after overseeding please feel free to contribute ideas, tips or questions to the site.
