Does anybody know what they seed with? Just curious because I may be building a grass court later this spring and I would want a good blend to work with. For that matter, what do they use at Halle? In general, I'm looking for a blend that has a solid durability, is hearty in a mixed climate, and also one that is better for a faster court/more traditional grass surface. Suggestions/ideas/info on the clubs? Any help is greatly appreciated.
