Indianapolis Pollen Counts September 11th through 17th, 2017

Ragweed started off on the 11th and 12 at high values, 53 and 50 respectively. Since last Tuesday, the counts have dwindled to moderate levels 14-37. Those other weeds, chenopods and nettle, have mostly  been low – for 5 of the past 7 days. Interestingly, grass pollen has been at moderate levels for the 11th, 15th and 16th. My thought is that this is not the usual ‘lawn’ grass that dominates the pollen season mid May to early July. This grass pollen is from ‘ornamental’ grass.

Ragweed 9-11 to 9-17
