Top dressing is applied to a lawn if it is poor condition, usually following mechanical works such as scarifying or aeration. The dressing will level out minor imperfections in the lawn surface whilst creating an environment where new seed can successfully germinate. This process is usually carried out during the spring or autumn.
What is Lawn Top Dressing?
Many types of top-dressing products are available, usually made from a mixture of sand and loam or refined organic compost. The percentage of sand and loam is stated as 50/50 or 70/30. For example, 70/30 top dressing would be 70% washed sand and 30% fine loam.
Organic soil conditioner top dressing is fast becoming very popular with lawn care professionals because it is derived from well-rotted garden waste. When applied, it is ideal for putting organic matter back into the soil whilst assisting seed germination.

After applying top dressing
After top-dressing, your lawn should not be mowed until the grass has recovered to approximately 2-3 inches long. Be aware that newly germinating seed will be starting to emerge, and the lawn may take many months to recover. Water daily during periods of dry weather to assist recovery.
