Why Grow Apios in Quebec?
Apios is well adapted to Quebec’s temperate climate and provides numerous benefits :
Highly Nutritious : The tubers are rich in protein, fiber, and essential nutrients.
Perennial and Low Maintenance: Once established, apios returns yearly with minimal care.
Soil Improvement: As a nitrogen-fixing plant, it enhances soil fertility naturally.
When and How to Plant Apios?
Planting Period
Apios tubers should be planted in early spring (April-May) or (September-October) to allow for proper root development.
Soil Preparation
Choose a moist, well-drained, and nutrient-rich soil.
Loosen the soil to a depth of 30 cm to encourage tuber formation.
Enrich the soil with compost or organic matter.
Planting the Tubers
Plant tubers 5-10 cm deep, spacing them 30-40 cm apart.
Provide a trellis or support, as apios is a climbing vine.
Water consistently, ensuring the soil remains moist but not waterlogged.
Apply mulch to retain moisture and reduce weed competition.
Care and Growth of Apios
Watering : Regular watering.
Support : Allow vines to climb for better growth and tuber production.
Fertilization : Minimal fertilization is needed, but adding compost annually can boost yields.
Harvesting and Storage
Apios tubers are ready for harvest in late fall (october-november), after the vines have died back. Carefully dig up the tubers and store them in damp sand or a cool, humid environment to maintain freshness (fridge is ideal).
