Seasonal Advice - Autumn
NOW is the time to fertilise. Warm Season Grasses such as Buffalo, Kikuyu and Couch that have been dormant over winter are very hungry for nutrient as the soil temperature increases. Light, slow-release type fertilising to recommended rates is advisable to assist in good colour and helping your lawn to reach its peak. Spread Sir Walter Slow Release Fertiliser evenly (for best results use a fertiliser spreader) and follow up with a good, deep watering. Liquid Seasol is a great soil conditioner which will also benefit your lawn.
Many lawn problems are caused by soil compaction as people and vehicles repeatedly move over the lawn. Wet soils are especially prone to compaction. If your lawn is not healthy and is full of weeds, the whole lawn may need treating for soil compaction.
Test for compaction by thrusting a garden fork into the ground. If the fork won't go in at least half way down the tines, the lawn is compacted. To relieve compaction for small lawns a simple garden fork can be used to aerate the soil.
Work the fork backwards and forwards at approx. 10 cm intervals to open up the soil. On larger lawns it may be worthwhile using an aerating machine (available for hire) that will help do the job quickly and thoroughly. Follow up with fertiliser (as above) and water in thoroughly.
