Instructions

Things You’ll Need
  • Pitchfork
  • Organic compost (optional)
  • Shovel
  • Stella d’Oro daylily plants
  • Organic mulch
  • All-purpose flower fertilizer
    1. Loosen the soil at the planting site with a pitchfork. Break up any large clumps. You can add some organic compost to the soil if the soil is poor.
    2. Dig planting holes that are the same depth as and 4 inches wider than the containers. Space plants 18-to-24 inches apart.
