Planting Guide
  • Choose the right location

    Plant tubers in a sunny, sheltered location with well-drained soil. Space 18-24 inches apart and water regularly. Apply a low-nitrogen fertilizer every 4-6 weeks and deadhead spent flowers. Lift and store tubers in colder zones after frost.
  • Prepare an appropriate hole

    Choose a pot that is 1-2 times larger than the current pot, ensuring there is adequent drainage to prevent waterlogging roots. Plan on repotting every 3-5 years.
  • Use fertile soil

    Choose soil rich in nutrients and with good drainage to support root growth.
  • Plant at the correct depth

    Plant at the same depth as in the pot, keeping the top of the root ball level with the soil.
  • Care and watering

    Water the plant appropriately, keeping the soil moist but not too wet.
