Visitors to this page have left the following comments| steve shull | Nov 05, 2011 | Seed starting-Mexican Hat-What is 22%G. I assume you're referring to Giberrilic Acid, but I don't understand the 22%.
Remainder of instructions-baggy method self explanatory. Germination time-4 to 9 days.
Thanks
The "G" stands for "germinated". For some reason, a relatively small percentage sprouted that year, but since ratibida sets plenty of seed that's not a big deal. |
