Lawn Care

It is time to give the lawn some attention. Follow the lawn maintenance schedule below and take note of our extra tips.


  • Mow once and trim the edges
  • Feed with lawn fertilizer with a high nitrogen content (calcium ammonium nitrate)
  • Dig up conspicuous weeds


  • Mow one or more times a week
  • Trim the edges every week
  • Feed with organic fertilizer (granulated cow manure) *
  • Feed with lawn fertilizer with a high nitrogen content (calcium ammonium nitrate) *
  • Re-sow bare patches


  • Mow one or more times a week
  • Trim the edges every week
  • Feed every month with calcium ammonium nitrate
  • Sprinkle in dry weather
  • Apply a top dressing
  • Aerate the lawn
  • September 
    • Mow one or more times a week
    • Trim the edges every week


    • Mow and trim the edges for the last time
    • Rake the leaves from the lawn

    * Allow 14 days between these two feeds, and always feed before a substantial shower (more than a few drops) or use the sprinkler.


    • In hot, dry weather it is advisable to postpone mowing.
    • Regular mowing is still necessary in August. If you mow three times a week, you can leave the grass cuttings on the lawn where they will soon disappear. If you mow less frequently, it is better to rake up the grass cuttings and remove them. In late summer it is also better to remove the grass cuttings.
    • If you use a mulching mower you can generally leave the grass cuttings on the lawn, but when you mow for the last time before winter it is better to collect or rake up the cuttings. You can remove the fallen leaves at the same time. A mixture of leaves and grass on the compost heap decomposes far better than grass alone.
    • Keep off a snow-covered or frozen lawn as much as possible, and never walk over the lawn when the thaw sets in as this causes damage.
    • The lawn should be mowed at least once every 8-10 days. Unless you use a mulching mower, the grass cuttings should be collected in a bag or collector or raked up.
    • A newly laid lawn needs sprinkling more often than an older lawn. A newly laid lawn also needs to be sprinkled during the day if the sun is shining. Although it needs more frequent sprinkling, this should be less intensive.
    • An older lawn should be sprinkled once a week during dry spells, but for longer and preferably late in the evening. Once a week is sufficient for an older lawn, whereas a newly laid lawn needs water more frequently.
    • If you want to sow grass seed, keep an eye on the weather forecast. Only sow if rain is expected, otherwise you will be wasting your time, money and effort.
    • The most favourable time to sow is in damp weather from 15 August to the end of October. This period is ideal for grass seed, as weeds present less of a problem, the soil is still warm, and the nights may be slightly longer but they are still warm and damp.
    • Most annual weeds freeze to death with the first night frost, so they will not be a problem.
    • If the weather is unexpectedly dry, you can sprinkle a newly laid lawn until the seed has germinated. You can also lay perforated plastic sheeting over the lawn to protect the seed from being eaten by birds.
    • Lawns needs frequent mowing and frequent feeding. This ensures a dense grass cover that is attractive and deters weed growth.
    • Weeds with tap roots must be dug out thoroughly, removing all the roots, as otherwise a new plant will develop from the remnants. They can also be sprayed with a weed-killer that penetrates down to the roots.
    • Bare patches should be lightly raked, then re-sown with grass seed, covered with a layer of earth or potting soil and watered. To prevent the seed from being eaten by birds, it can be covered with a sheet of (transparent) plastic until it has germinated.
    • If you hate trimming the edges of the lawn, you could separate the lawn from the borders with sleepers or impregnated wooden boards.
    • Do not throw too many grass cuttings onto the compost heap in one go. Grass has a high moisture content, and too much grass hinders the decomposition process.

    Sprinkling the lawn
    If the grass is cut very short and the underlying soil is dry and sandy, the lawn should be sprinkled daily, otherwise the grass will turn brown, by which time it is too late to do anything about it.
    The best time to sprinkle is at the beginning of the afternoon, as this allows the grass to dry.
    If a lawn is intended for playing rather than for decoration, the grass should not be cut too short. This also means that it will not need sprinkling as often. Once every other day should be sufficient.

    Feeding the lawn
    Feed the lawn for the first time in the season in April, using a lawn fertilizer with a high nitrogen content (calcium ammonium nitrate). Feed just once in April.
    In May you can use an organic fertilizer (granulated cow manure) followed by a nitrogen-rich lawn fertilizer - for example, with an NPK ratio of 12-10-18. 3-4 kg is sufficient for 100 m2. Allow 14 days between these two feeds.
    In June and July you should administer calcium ammonium nitrate once a month.
    The last feed should be in August. 1 kg per 100 m2 is then sufficient.
    Always feed just before a (heavy) shower, or use the sprinkler.

    Calcium ammonium nitrate
    Calcium ammonium nitrate is widely deployed as an artificial nitrogen fertilizer. Although the name suggests otherwise, this fertilizer does not add lime to the soil. On the contrary, it has a lightly acidic effect.
    The fertilizer contains 27% nitrogen and 4% magnesium oxide. Half of the active nitrogen is in the form of nitric nitrogen, the other half in the form of ammoniacal nitrogen.

    Use grass twice as ground cover
    Of course, a lawn is the perfect ground cover, but mown grass can be used to cover the ground a second time if it is scattered under bushes and shrubs and left to decompose. This is especially beneficial for shrubs with roots close to the surface of the soil. This allows the grass to be used twice as ground cover.
