When the frost is over, mow the lawn extremely short. This may look alarming, but will result in good growth in the coming season. Rake or brush out with a stiff brush, any dead and matted material. Then push the times of a garden fork into the lawn so that air and water can reach the roots, or use a roller if you have one.
Bare patches which were subject to heavy traffic should be dug over and the dead grass removed. Bring in good soil and plant it with grass, or cut squares of turf from other parts of the garden.
At this time, it is essential to encourage the roots to grow well, and an application of general fertilizer such as 2:3:2 or 3:2:1 (100 g per square metre) followed by a thorough drenching will do this. A slow release should be used if there is a shortage of water, as it is not necessary to water immediately after application.
A good growth of grass will help to keep the weeds down, but weeding should still be carried out on a regular basis. Weedicides are of great help, and broad-leafed herbicides can be applied. Good soaking should be given and, later in the season, a fertilizer high in nitrogen or urea can be applied.
Aim for a clean uncluttered look, with no fussy beds to break the flow. Soil must be prepared by breaking up any lumps, then raking it over to make sure the surface is level. add 2:3:2 (50 g per square metre) and rake it in, in two directions.
If seeds are to be sown, scatter them evenly over the raked surface, then gently rake them in by drawing the rake in two directions. The quickest way of establishing a new lawn is to buy ”instant” lawn, which is expensive, but time saving.
Regular and ruthless weeding must take place from now on, and watering should be gentle. Keep the mover blades at a height of about 10cm for the first mowing.
