Your Guide to a Great Lawn

October 10, 2017



  • Good soil preparation is the key to achieving a good lawn

  • Spray out weeds with a glyphosate weed killer such as Roundup

  • Allow 10-14 days for weeds to die and brown off

  • Soil should be dug to a depth of 15cm - break up large clods and remove all stones and debris

  • Well -drained, loam soils are best

  • If soil is clay or very heavy, apply Gypsum and work in some sandy soil

  • In very wet conditions, artificial drainage may be necessary

  • If soil is sandy and free draining, add compost, peat to improve its water holding ability

  • Rake and level, filling in hollows and removing high spots

  • Slope lawn away from house and other buildings

  • Tread and rake the area several times to consolidate and stop further sinking



  • Apply General Garden Food to area prior to sowing

  • Alternatively use a slow release lawn food such as Lawn Builder

  • Once grass is established, feed with Lawn Food in spring and autumn

  • Never fertilise in dry conditions


Sowing Seeds

  • Sow in calm weather

  • Sow in early morning

  • Mixing seed with some sand helps even spread

  • Sow seeds in two directions, walking backwards across lawn, North -South, East - West

  • Ensure even coverage - avoid dumping seed in patches

  • Sow at 30gm/m²

  • Keep surface moist with light watering until seeds germinate, ie. at least daily

  • As seed grows water more heavily but less frequently, i.e. every 2 days



  • Mow frequently for best results

  • Avoid cutting too low or ‘scalping’

  • Cutting height between 2.5 -4cm is ideal
