It’s best to stick to the 2 to 3 grams a metre rule as that’s how we’ve formulated the meadow designs but don’t worry too much either way. 3 grams and you will get a thicker, more boisterous display. It will probably look amazing early on but be a bit too competitive for a fantastic late display. Exactly the opposite if you’ve gone down to 1 gram. It might look very sparse to start with but often this is compensated by each individual plant growing much bigger and some amazing late season meadows.
