In Quebec (Canadian Zones 4b–5b), direct sow carrot around April 3. Carrots grow well in this province with appropriate variety selection and standard Canadian planting timing.
What is the best carrot variety for Quebec?

Can I grow carrot in containers in Quebec?
Yes. Container growing on balconies and patios extends the viable growing area across every Canadian province. Dark-coloured containers warm up faster in spring and extend the season on both ends. Choose a 5-gallon or larger pot for carrot and water daily during hot summer weather, since containers dry out quickly.
When is the first fall frost in Quebec?
