Planting ipomoea

In tropical environments it grows as a perennial, but in colder latitudes it grows as an annual. It won’t grow back from the same plant year after year.

Sow under cover starting from the month of March, transplant in April and plant in the ground starting from the month of May in a blend of earth, soil mix and organic soil conditioner.

  • Soak the seeds in lukewarm water for 1 hour before sowing to trigger sprouting.
  • It’s also possible to sow directly in the ground starting in mid-May but blooming will only occur much later, which is a bit sad for an annual plant.
  • Place Ipomoea indica in a very sunny spot.
  • Place it next to a spot that is often used like a terrace, to fully take advantage of its beautiful blooming.

Growing ipomoea in pots

Growing ipomoea in pots is perfectly possible and it even makes a lot of sense to decorate a terrace or balcony.

  • For that, select a pot that is wide enough, about 12 inches (30 cm).
  • Ensure that the bottom of the pot has a hole in it and ideally pour a bed of clay pebbles along the bottom.
  • Fill the pot up with flower plant soil mix.
  • Water as soon as the surface soil is dry without flooding the plant.
