Soak the seeds 24 hours before planting, in place of soaking in water, you can soak them in pulpy passion fruit juice or warm water, milk, or tea. The acid helps break down the seed shell and helps in germination.
It is best to start Passion Flower seeds in containers indoors.
Kept at 75-80°F., germination occurs unevenly over a period of 30-90 days. Providing bottom heat can lower the days to germination by up to 50% or more.
Seeding depth: ¼ inch deep
Once Passion Flower seedlings have 4 - 5 leaves, they can be hardened off and transplanted into the garden.
Passion Flower plants need to be well watered through out the summer months, watering infrequently but deeply to encourage deep root growth.
During the winter months keep the soil on the dry side so it will go semi-dormant.
Must be planted in well-draining soil mix, equal parts gravel and soil.
