Fungi, the Bogeymen?

The highly sandy nature of many bowling greens and the historical routine use of fungicides of course means that the fungal community is at best compromised. However, we can encourage they're development by providing bio-stimulants. These are typically long-chain sugars such as—kelp, humic acid, and molasses derived bio-stimulant materials. In fact, trials have shown that spraying Trichoderma fungi (a natural Fusarium suppressor) with 20 litres of a biostimulant such as Molturf per hectare extended its protective activity for over five weeks. Even at lower rates, molasses is a highly effective and underutilised biostimulant.

The thatch dilution delusion

The thatch dilution delusion...discuss. Can thatch be diluted? If so, is there any benefit in doing so? As with many aspects of modern greenkeeping that have been accepted as fact without evidence, the claims for top-dressing's ability to dilute thatch fly in the face of the science.

Seaweed for Bowling Greens: Ancient Input, Modern Results

Beyond plant growth, seaweed feeds the microbial community that underpins a healthy green. Polysaccharides like laminarin and fucoidan stimulate beneficial soil microbes, improve aggregation, and enhance nutrient cycling.

Fixing low pH without Lime

As standard soil analysis offerings are generally obsessed with chemistry, a very low pH is often interpreted as a chemical imbalance, which, of course, it is. The question of why those acid cations are dominant on the soil colloid, remains unaddressed in most cases. Instead it seems that many advisers are jumping straight to the temporary, artificial correction advice to add lime, and as we have seen, for fine turf, that can be dangerous advice.

Fusarium. Why It’s Getting Worse, and What to Do About It

Over the last few decades, routine applications of fungicides, high-salt synthetic fertilisers and ever-increasing topdressings of sand have left many UK greens biologically bankrupt. I see it time and again in soil analysis reports: textural classification coming back as just “Sand”. Very little in the way of silt or clay and sparse organic matter. No biological cushion.
