Polemonium Growing Tips
  • Plant in a well-drained soil that has been enriched with organic matter.
  • Before planting make sure the pH of your soil is within a 5.5-7.0 for optimum growth
    and flowering.
  • Incorporate compost into the planting hole to feed a growing plant and encourage an
    even soil moisture.
  • Jacob's Ladder plants prefer protection from hot afternoon sun and like growing under
    the edge of deciduous shade trees.
  • Keep soil consistently moist for best performance.  Normal rainfall is sufficient, but in
    areas where rainfall can be scarce irrigation is needed.
  • Mulch plants to conserve moisture and for added winter protection.
