To solve problem for safe over summering of cool-type Festuca Arundinaces Schreb in Wuhan, we carried on a contrast test under lawn of Festuca Arundinaces Schreb over different seeding quantity. The experimental results showed that the first class seeding quantity would be suitable between 15-25 g/m^2 and the best was 20 g/m^2. It is good for the growth of the lawn and safely tolerates summer.
