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?
How warm has it been for you during these sowing attempts?
"Carrots (Daucus carota) are cool-season plants that grow best at
average temperatures between 60 and 65 F. The optimum soil
temperature for seed germination is 55 to 75 F. Seeds will not
germinate above 95 F."

One fairly traditional tactic to get carrots to germinate in summer
temperatures is to put a board over the row to keep the soil cool
and moist. Check the board a couple of times a day and remove
the board once you notice seedlings beginning to emerge.
