Here in New York at latitude 41 deg. Equisetum arvense fertile fronds emerge in 
the third week of April and are followed several days later by the first of the 
sterile fronds. The overlap is short with fertile fronds senescing quickly.

I've not noted the last fertile frond emergence date, but by May 1 they seem to 
be on the way out.
