Vegetable and fresh herb sowing calendar

Harvesting fruit (and vegetables) from the garden is one of the joys of summer. When sowing, certain dates must be respected in order to maximize the harvest. The calendars below indicate which moment to plant vegetable and fine herb seeds, at what depth, and when to transplant them to the garden.

Indoor sowing

Certain vegetables need to be planted before spring in order to give them the chance to mature by the month of August or September. To do so, we plant the seeds in small plantable pots or peat pellets in March or April and place them in a warm and sunny area in the house, watering them regularly.

Pro’s advice

Sowing too early could have as harmful consequences on the crops as sowing too late. Make sure to respect the planting dates. Note that dates may vary from one region to another.

Outdoor sowing

Certain vegetables, like root vegetables, resist better to the cold weather and should be planted directly outside. We therefore skip the transplantation step.

Pro’s advice

Seeds should be planted 4 times deeper than the diameter of the seed. For very small seeds, like carrots or parsley, simply cover them with a thin layer of soil.

Fresh herb sowing

Fresh herbs enhance the flavour of your meals. Why pass them up when they are so easy to grow?

Pro’s advice

Coriander bolts quickly. If you’re a fan, start sowing seeds every two weeks to ensure a summer-long harvest.
