OPS eliminate

Ina I like the sponge-tip idea. I will try that. 
Your victory over Ops is inspiring. 

Chad - was the solarizing heat with the soil soaked or dry? 
The double-spaced layering is a great idea. I wonder how hot it gets, how deep. 
The Ops in my yard are found awfully deep. 
I have photographed some of the deeper complete plants (corm and underground stem) to document just how far deep these grow. 
I assumed they would have to be in growth to be killed by heat. 

Alberto - if I wait too late in the season they will have made the little cormlets all along the sides of the underground stems. I do see the logic of reduced recovery time. So, late season, but not too late season.
