The first 12 months are critical in establishing your new turf.
All soil has weed content in it, and you would expect weeds to germinate. This is normal and once you have mowed your lawn 3-4 times you can spray your weeds using a soft herbicide like MCPA to control the broadleaf weeds in your grass. The time of year your lawn is sown will dictate the type of weeds that will germinate as soil temperature will define what weeds will establish in your lawn and turf.
Fertiliser is an important tool in establishing your new lawn or turf. Fertiliser is applied when your hydroseed or turf is put in and gives your lawn its first boost to make it germinate. It is recommended that you look at applying a second application of fertiliser 6-10 weeks after the hydroseeding or turf is put in. The timing of the fertiliser application is dependent on your soil type and base fertility. If you see your young grass going yellow this is a sign of low fertility.
Due to the lawn being newly constructed and lacking any soil structure, it will take regular fertiliser treatments for the first 12-18 months to build up the base fertility and to regain soil structure. This takes a few seasonal changes of wet then dry weather for microorganisms to re-develop. New lawns do hold water because the surface is sealed off during construction. This is short-term and quickly improves over a couple of months once the grassroots get down and earthworms in the habitat of the soil.
