About 3 weeks ago I sowed a new lawn, can you advise on what fertiliser to use on it now please. The topsoil was screened at purchase and I didn't put any fertiliser on it prior to sowing.

• Newly sown lawns do not need fertilising as the seed has enough 'food reserves' to sustain the grass for at least 8-10 weeks.
• However, feeding the lawn will help it establish quickly
• The best fertiliser to use on a new lawn is Tui LawnForce New Lawns slow release lawn fertiliser.
• It is applied to a dry lawn and then watered in well. 
• LawnForce New Lawns slowly releases nutrients for up to 10 weeks and is a low nitrogen formulation to prevent fungal diseases in new lawns. 
• Blended lawn fertilisers such as Tui Lawn Fertiliser are too concentrated to use on a new lawn and should only be applied after the lawn is 14-16 weeks established.
