Answer: Autumn is usually the best time to top dress but in Florida, you can do it in early spring. The type of mix to be used varies according to your basic soil type. Normally, I use equal parts of sifted top-soil, sharp sand and compost or peat. For Lawns on heavier soil, I would leave out the soil in the mix, and use 50/50 sharp sand and peat/compost.
Mix the ingredients well, ensuring that there are no lumps in the mix.
Lightly spread to mix over the lawn. You will want to apply one quarter to one half inch to your lawn. It is better to do it lightly and in several applications throughout the season, rather than 'smother' the lawn grass in one go!
I normally use the back of my wide rake to spread the mix and 'brush' it into the grasses of the lawn. A good stiff broom will also do the trick. Make sure that the mix goes down into and below the grass blades. Then water the lawn to help settle the top dressing.
