Is the "grass" countable or non-countable?

"Grass" is both countable and non-countable. The grass in your garden is uncountable, "I'm going to cut the grass" not "grasses". However, there are different types of "grasses".

Is the word "grass" correctly used in this context then??

I would introduce an annual high tea function, where everyone can enjoy ambient music and civilized conversations with other club members, a few more annual "Dress up for the theme day", where we meet up dressing
up like the theme characters e.g. Alice in the wonderland, a soccer competition, or just simply gather for a nice outdoor picnic that involves
lots of green grasses, music, mini games and some nice sun.

Thanks heaps.

You should use 'grass' singular. I have suggested some alterations.
