Lawns Seed Growing Guide

Step 1. When to Sow?

Lawn seed may be sown from March to September. 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.

Step 2. Preperation....

New Lawn: Firstly prepare the soil by cleaning away any debris. Dig out any perenial 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.
- 4-5 days before sowing the seed, lightly rake in Growmore.
- The day before sowing, water throughly if the soil is dry and leave to soak over night.

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.

Step 3. Sowing....

Tear back the side strip to sprinkle the seed. Apply the seed at a rate of 33g/m2. 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.

Step 4. 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 thotoughly once rather than several times lightly.

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

TIP - Alternating the direction of the mowing encourages the sward to thicken out
