If you work out why your lawn has deteriorated, you can use that knowledge to make the right decisions during your renovation. For example, if the lawn has thinned out due to growing trees that shade the lawn and compete for water and nutrients, you should select shade-tolerant grass varieties. You might also want to prune some of the tree limbs, opening up for more sunlight and rainfall.
开始实际翻新第一步，通过手动或使用除草剂去除杂草，特别是多年生杂草。 This keeps other species from competing with your new grass. If you use herbicides, be sure to read the labels and follow the instructions. Most products will allow you to seed in seven days, but some weedkillers will keep your seeds from germinating for three to six weeks.
Check your thatch status by digging up a small plug of turf, several inches deep. If the spongy layer is more than three quarters of an inch thick when you compress it, it’s time to have your lawn dethatched. If your lawn is larger than 300 square meters, you would want to use a power rake or a vertical mower with a scarifier. For smaller lawns, a manual thatching rake will do.
