how to grow ipomoea aquatica from seed and....
I bought some seeds from Ipomoea aquatica and would like to grow them in a container submerged in my pond as an annual flower, not for food. The plant is not invasive in my country as it is to cold during winter.
How are the seeds germinated?
Do I have to nick or soak them?
What soil is best?
When they have germinated, can I put the pot into the pond?
How deep should the water be over the crown?
What temperature should the pondwater have?
Many questions but I hope to get information from this forum.
