Gastil, see below answers - Chad -----Original Message----- From: firstname.lastname@example.org [mailto:email@example.com] On Behalf Of Gastil Sent: Monday, July 23, 2012 6:43 PM To: firstname.lastname@example.org Subject: Re: [pbs] 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? [Chad Schroter] Soaked, plus had a soaker line under plastic to make sure soil did not dry out. The double-spaced layering is a great idea. I wonder how hot it gets, how deep. [Chad Schroter] I used my compost thermometer to measure temps getting up to 120 degrees in top 6 inches The Ops in my yard are found awfully deep. [Chad Schroter] I find the repeated weeding will exhaust the main bulb, and the remaining stem generates the bulbs for the next season at a more shallow depth 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. [Chad Schroter] I think the solarization took care of some of the smaller offsets which form off the stem each Spring. 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. - Gastil Zone 9b (sort of), Cool Mediterranean ________________________________ PLEASE NOTE: The information contained in this electronic mail message is intended only for the use of the designated recipient(s) named above.
