Natural greenkeeping is about rhythm, not routine. And the best greenkeepers are those who tune into the biology of the surface—not just the calendar on the wall.

I am frequently asked about the difference between our 80/20, 60/40 and 40/60 Premium Fescue/Bent Grass Seed Mixes. On the surface, it might just look like a simple percentage change, but there’s quite a lot going on behind those numbers that can affect both the long-term performance of your green and the cost of the mix.
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.
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.
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.
