Which Method Is Better?
If you want speed and simplicity, use the egg carton as a soil marker.
If you want maximum control, better germination, and less thinning, plant directly in the carton.
Both methods help solve the biggest problems with carrot sowing: uneven spacing, wasted seed, and messy rows. With a little preparation, you can grow carrots in a cleaner, more organized way and enjoy strong, healthy roots at harvest time.
