Dr. Russell Sharp explains what fairy rings are, why they become visible after droughts, and how their hydrophobic exudates and waxy residues can cause grass death and uneven growth on lawns and sports turf.

He outlines practical management: maintain irrigation, reduce thatch, use wetting agents, consider spot applications of lime sulfur as an organic soil sterilant, and reseed damaged areas. Fungicides are of limited use for soil fungi, so targeted, cautious treatments and cultural control are recommended.

Dr. Russell Sharp takes a deep dive into flooding and waterlogging across gardens, farms and sports turf—explaining causes like clay pans and heavy rain, the physiological damage to roots and crops, common symptoms such as patchy chlorosis and shallow rooting, and secondary risks like nutrient loss and pathogen spread.

The episode also covers practical treatments and prevention: why you shouldn’t work wet soil, mechanical drainage and mole ploughing, liming and gypsum, organic matter and mycorrhizae, plus Utrema’s liquid gypsum solution that can improve drainage without digging—useful for lawns, golf courses, allotments and arable land.

Dr. Russell Sharp explains why pouring liquidised food waste or adding fresh, uncomposted plant material to soil or lawns can harm plant growth. Microbes breaking down this material consume available nitrogen, causing nitrogen deficiency and chlorosis in your plants, and fresh food waste can also attract pests like rodents and rabbits.

The episode advises always composting organic matter or significantly increasing nitrogen if you must add uncomposted material, and warns about common sources such as grass clippings, manure, and mulch.
