It could be time to plant plants such as snowdrops
Jonathan added: "If your grass needs a boost apply a balanced slow-release fertiliser during September.
"This should be done after scarifying and aerating but before applying a top dressing. A slow-release fertiliser will encourage hardiness and root growth.
"Spring-flowering bulbs such as snowdrops, crocuses and daffodils are often planted into a lawn during autumn ready to add colour and attract pollinators when the spring season arrives.
"You will need to leave the planted area for several months in spring without mowing so it can be best to plant in a specific area where grass can be left a little longer, rather than planting across the whole lawn."
