Over-seeding a ‘safe option’ in dry soils

He says there is a ‘narrow window of opportunity’ for a full re-seed, as ideally seed needs to be in the ground by mid-August. This is especially so if clover is included in the mix, as it needs to be planted three months before the first frost to ensure its survival.

Parched soils in the south and east of the country may make over-seeding a safer option.

“This is the ideal time of year for over-seeding, as the sward is now less aggressive,” says Mr Morgan.

“Over-seeding is a cost-effective option which can extend the life of a sward for two to three years, and is less risky than a full re-seed in these drier conditions.”

He advises using seed at a rate of 0.5-0.75 of a full re-seed, except in the case of white clover, where rates could double.

“There are a number of methods available when over-sowing, including using a grass harrow or slot seeding with specialist drills,” he says.

“The most important thing is to get good seed-to-soil contact, so a slot seeding approach may be best in the current conditions. This method could also help optimise moisture content inthe soil.”
