I get a load of email every week asking about the best way to fix a bowling green and you would imagine that it is difficult to give advice that applies to all circumstances and of course this is correct, but only to a certain extent.
I believe it is possible to give advice that is applicable to almost every bowling green, at least in the UK, but of course there is a caveat…or actually 2 caveats.
How is it possible to claim this? Because, every green that is experiencing difficulties is at some stage of what I have called the Circle of Decline. If you’ve been a regular here for any length of time you will have experienced me banging on about the Circle of Decline. So, to give good advice, it is only necessary to know where we are starting from.
Performance Bowling Greens goes through this process step by step.
To the caveats:
- You must be prepared to do some investigative work to find out what stage your green is at.
- You must be prepared to listen to what your observations tell you and accept that there is no miracle cure you can buy in a bag or a bottle regardless of what the salesman says and regardless of how attractive this road sounds compared to what I’m going to recommend.
Assuming that all of the above is understood and agreed, we can move on to today’s simple task:
Step 1. Find out what you’ve got:
So lets see if I can help you to fix your bowling green!
The best way I know of starting this is to have a look at what’s going on under the turf and you can get a good idea of this by taking a deep profile sample that will show you a cross section through the green. The best method is to use a sampler like the one below:
You are looking to establish the depth of the thatch layer, any distinct layers in the profile, any funny smells from it and how moist or dry it is. If you can get a deep sample (deeper than 150mm/6″) you should be able to see the contrast between the natural soil the green was built with and the “improved horizon” (top 100mm/4″) where all of the top-dressing has been going over the years. You should also be able to detect any hard, compacted pans as you try to get the sampler in. Make a note of the depth of any noticeable hard layers.
Take several samples across the green and note down what you see with reference to the above points. If you can take a sample across the boundary of a normal area/brown area you might be able to see a marked difference in the conditions below the turf. A sample taken from an LDP affected area will typically fall apart as the soil will be powdery dry.
Let me know what you find out and send photos if you can. You can send it all direct to me using the email link at the top of the page.
That’s it! That’s all you have to do this weekend…easy eh?
Next time we will analyse the sample to see if we can identify any problems. Happy digging! (a border spade will do in place of a soil sampler)
