When to sow

Lawn seed may be sown from March to October. However, for best results, sow lawn seed in the spring from March to May, and in the early autumn from mid September through to mid October.


New lawn

Firstly prepare the soil by clearing away any debris. Dig out any perennial weeds and treat the area with weedkiller. Once the soil is clear of weeds, prepare a seedbed: On a dry day, dig over the soil to a depth of 20-25cm (8-10 inches). Break down any lumps and tread the soil to firm it again. Level out any bumps or hollows using a rake, aiming to create a flat, even surface. The day before sowing, water thoroughly if the soil is dry and leave to soak in overnight.

TIP – The top of the soil should be dry with moist soil just below the surface on the day of sowing.

Existing lawn

Remove any weeds either by hand or by using a selective weedkiller treatment. Once weeds are dead, mow the lawn closely before raking or scarifying to remove any moss and weed remains. If the ground appears hard or compacted aerate using a garden fork. Finally, spread Westland Lawn & Turf Dressing to fill any shallow holes and to level-out the surface.


Apply the seed at a rate of 40g/sq.m (30g/sq.m for lawn repairs). As a guide one large handful is approximately 40g. Sprinkling the seed in 2 passes at right angles to each other will help spread the seed more uniformly. Lightly rake to gently incorporate the seed into the surface.

TIP – Shake the box of seed thoroughly to mix up the seeds and weigh out the amount required to cover the site.

After sowing

Rolling: The ground should be rolled or lightly firmed by walking over it and pressing the seed into the soil.

Watering: Water the lawn thoroughly using a fine-rosed watering can or a lawn sprinkler which produces a fine spray taking care not to wash the seeds away.

TIP – If sowing a new lawn in very hot conditions the lawn should be watered late in the day once the sun has gone down. It is better to water thoroughly once rather than several times lightly.

Mowing: Grass can be cut for the first time when it is 5-8cm (2-3inches) high. A light trim will be sufficient initially. Gradually lower the cutting height to about 2.5cm (1 inch), which is ideal. Do not remove more than 1/3rd of the growth at any one time.

TIP – Alternating the direction of the mowing encourages the lawn to thicken out. Feeding: After 10-12 weeks we recommend feeding your new lawn with Aftercut 3 Day Green Lawn Feed. Simply apply after mowing for quicker more visible greener results in 3 days.
