Carrots All Year Round

This post by Sarah Backmo  https://www.sarabackmo.com/growing-carro...y3-eYD2hbY about Growing carrots (and eating carrots) all year round looks useful and challenging!
I don't have much luck growing carrots, not really thought about  summer or winter carrot seeds so I'm thinking of trying Sarah's planning schedule:- 

Instructions:

1. Late fall/winter: Winter sow summer carrots outdoors, in a sheltered spot
   
   
2. Winter: Winter sow summer carrots in a polytunnel
   
   
3. Early spring: Sow summer carrots outside or in a planter box
   
   
4. Early spring: Sow winter carrots outside (in one or two beds)
   
   
5. Late spring: Sow summer carrots outside/in a planter box
   
   
6. Early summer: Sow summer carrots outside/in a planter box
   
   
7. Summer: Sow summer carrots outside/in a planter box
   

 
I also try to sow some carrot seeds in my hotbed, if I have the space. I sow these seeds in February and start harvesting my carrots in May. The seeds will of course grow in the order they were sown. The seeds in the polytunnel might get a bit of a head start though, depending on how sheltered they have been.
