If your lawn loses its colour and the tips of the blades of grass turn a yellowish colour, this may be a sign that the grass has been cut too short. To be on the safe side, you should never cut your lawn any shorter than four centimetres. As a rule of thumb, each time you mow the lawn, cut the grass by approximately one third of its length.
A patchy lawn can be a sign of incorrect irrigation. In addition to a regular supply of water, it is important for the grass to be kept clear of old leaves and foliage at all times. This will ensure it receives a constant supply of air, light and water.
If your lawn does not recover even after four weeks, reseeding is recommended. In serious cases, it is advisable to consult a professional landscape gardener to help eliminate more deep-rooted problems with your lawn.
