Fertilizing Tips

  • The amount of fertilizer should not exceed 1 tablespoon per foot of height.
  • Apply fertilizer when the foliage is dry so it does not stick and cause burning.
  • Sprinkle fertilizer evenly on top of the soil, over the root zone.
  • Keep the fertilizer 4-6 inches away from the stem.
  • Water lightly.
