I'm having terrible luck germinating carrot seeds. The varieties are "Baby Babette", "Round Romeo", and "Sunshine Orange and Yellow", all from Renee's.
I'm sure that the seeds are fresh. Everything else we purchased from Renee's has been excellent, this is not an indictment of the vendor.
Per the package instructions the seeds were sown 1/4" beneath the soil and kept moist throughout the 10-20 day germination window. The soil is San Joaquin Delta peat contained in raised beads. This soil has not had carrots sown in it before now. "Baby Babette" and "Round Romeo" failed to germinate at all in both of two successive sowing, and "Sunshine Orange and Yellow" germinated at less than a 50% rate.
USDA zone 6, Sunset zone 7 and/or 9.
Any ideas what we may be doing wrong?
