Why are agaves not going to seed?

First I heard from Sergio Garnier that the wild lamparillos on his 24,000-acre ranch in Durango skipped a season. Didn’t shoot quiotes. Didn’t go to flower. Then I heard the same about the agaves in Guerrero from Damian Meneses from El Tigre. And Damian and I were in Jalisco together and he told me that the raicilleros were saying the same thing: none or almost none of the agaves are going to seed. So … what’s up?
