I guess I think of Maigret as being small (not to be confused with very small), because so many of mine are large, or really large.
Okay, I'll share my secret on how to grow them.
1. Plop them out in the elements and let them sink or swim (the swimming part applies to the PNW).
2. I don't fertilize (It surprises me that they are so plump, you'd think they would be all skinny from lack of food.)
