Tips for growing Giants

  • Avoid planting in a windy site or too near a wall. A north facing area may help the plant grow tall. Plant in sun for branching and lots of flower.
  • Stake the plants for support. Put in a thicker stake as needed.
  • Mound up soil around the base of the plant
  • Water regularly
  • Feed at least weekly with balanced feed and more frequently with a high potash feed when the flower develops.
  • Watch out for insects, wind damage and other problems that need quick treatment.
