Turf Care

Turf Heating

During humid and hot weather conditions, turf must be unrolled immediately upon receiving the turf delivery to prevent ‘turf heating’ – here’s what to look out for.

Does your turf look yellow, black or ‘greasy’ and does it have a stagnant smell, or has it got brown patches or streaks?

If the weather conditions are humid and hot and your new turf has these symptoms within the first day or two following installation, or when you have unrolled it, the turf might have been rolled up too long and have suffered from heat stress.

Description of turf heating

New turf rolls contain living grass plants, they are breathing all the time. Cool turf breathes slower than warm turf and when turf is rolled up it acts like an insulating material, slowing down how fast heat is exchanged with the air and during humid and hot conditions, the pallet of new turf rolls can quickly turn in to a mini-compost heap. There is more to ‘turf heating’ than just overheating, other factors are at work too. Within a turf roll there are microorganisms that breathe or consume the oxygen, as the oxygen is used up, other organisms that need very little oxygen become active, as they start multiplying, they too generate heat. Because rolls of turf act like insulation, it traps this heat in and just gets hotter especially on humid and hot days. At first the heat will cause the grass to turn yellow or black, if the heat isn’t released by unrolling the turf, it may kill it. This can happen within 24 hours after the turf is harvested.
