A 25 foot row of carrot seed was planted. Method is to mark the row, rototill, flatten surface, place seeds along row three across insuring no seeds touch,(if seeds touch the stalks will be intertwined) water, place supports and place board over the row.The supports under the boards allows space for the shoots to grow without distortion. This method insures the soil surface temperature does not get too high (above 80F) and the seeds tend to remain moist. If it rains the seeds do not get washed out of position. Germination is almost 100% using this method with little care required. Either take care and the effort when planting, or one has to thin later, which is difficult and time consuming.

The carrots germinated in 20 days using the board method. Germination at first look appears to be high. It has been very cool during this gestation period. But 20 days is fairly typical for carrot seed to germinate. Eleven days germination occurred once.
