Growing tips
Germination conditions:
- seedling depth: 2.5 mm or surface sow
- optimal temperature for germination: 10 to 22ºC
- time for germination: 7 to 14 days
When to sow:
- indoor sowing 4 to 6 weeks before the last frost date in your area OR
- direct seeding when the soil can be worked in the spring (2 to 3 weeks before the last frost) and towards the end of July/beginning of August for a fall harvest
Sowing technique: in pocket
Inside the same hole, sow 3 to 5 seeds spaced 1 to 2 cm apart; when the seeds have germinated and the seedlings have reached a height of 5 cm, keep all the plants if space is available or keep only the best plants.
- for indoor seedlings: transplant into individual containers while waiting for transplanting in the garden OR
- for direct seedlings: transplant to their final location in the garden
Transplanting outdoors (for seedlings started indoors):
- Planting in the garden when the soil has warmed up: after having hardened off the plants for a few days outdoors, plant in soil with a prior application of compost, keeping the stem slightly above the soil so as not to bury the central bud.
Distance in the garden:
- between plants: 20 cm
- between rows: 45 cm
Soil: loose and well drained
Watering: regular and moderate
Exposure: full sun or light shade
When to harvest: 45-65 days for mature leaves
Recommendations:
- Mulching the base of the plants helps keep the soil cool and moist and helps control weed growth;
- Adding organic matter (homemade or commercial compost or decomposed manure) or a natural fertilizer once or twice during the season is beneficial for the plants.
