It is made of undecomposed grass stems, blades, roots and rhizomes, which collect between the green vegetative part of the lawn and the soil. Several factors make for a faster build-up of thatch – heavy, compacted soil, inadequate soil preparation prior to seeding, excess of undecayed organic [...]
