All bowling greens play host to a population of micro-organisms numbered in the billions and this can be split down further into smaller groups such as fungi, bacteria and nematodes, all of which have a role to play in maintaining a healthy bowling green.
In many modern bowling green rootzones—especially those high in sand and low in organic matter—these vital organisms are either missing or severely suppressed. Without a thriving microbial community, thatch accumulates rapidly, leading to a lifeless, compacted surface that invites disease and drainage issues.
The Role of Microorganisms in Soil Health is vast and in many cases misunderstood. For decades we have been obsessed with the potential harm that just a few pathogenic microbes can cause, instead of learning to think of the soil as an eco-system. We've learned the hard way about that approach and now that pesticide availability is being reduced we need to start taking this seriously.

Microbes are hugely important in bowling green maintenance, but did you know how important they are to human existence? In this talk Rob Knight explains the findings of his recent research which show just how important microbes are to humans. Mostly nothing to do with greenkeeping, but a lot of interesting parallels with the discussions we have here on bowling green eco-systems.
Across the UK this summer, bowling greens are being baked in the intense summer heat. Weeks of hot, dry weather have left surfaces bare, cracked, and rock-hard. For many clubs, the underlying soil has crossed into a more serious condition — hydrophobicity — where the soil physically repels water, a phenomenon known as Localised Dry Patch.
If that’s where your green is today, you’ve got a problem.
You can simply can't wait until your usual mid-September renovation
