Show Me Your Autumn Renovation

One of the most useful things we can do is share real examples from real greens. Your photos and updates could help another greenkeeper understand what to expect, give them confidence to try a different approach, or simply reassure them that what they are seeing on their own green is perfectly normal.

Peak Sand Analysis Texture Only

It’s Not Too Late for Soil Analysis!

We can establish that quickly with the Peak Sand Texture Only Analysis. Using laser diffraction, the laboratory measures the actual percentages of sand, silt and clay in your rootzone and plots the result on the Soil Texture Triangle. A soil test that gives us something far more useful than guesswork. We will instantly know whether your green genuinely needs more mineral material — or whether years of conventional top dressing have already pushed it towards the excessively sandy conditions I call Peak Sand. This information can completely change the autumn renovation programme.

Phosphite Ion

Phosphite and Disease Resistance

Phosphite (PO₃³⁻) is a reduced form of phosphate (PO₄³⁻), the familiar phosphorus source in traditional fertilisers. Although the two compounds are chemically related, their behaviours in plants and soils differ significantly. Phosphite is highly soluble and readily absorbed through both roots and foliage, making it a highly efficient delivery mechanism for phosphorus-related benefits, including disease and pest resistance, acting as a trigger for some of the plant's remarkable natural defence mechanisms.
