NOTES:

In shady sites with dry soil, plant choices are very limited. And, because shaded sites are often under trees, root competition limits space for planting and provides competition for the limited water in the soil.

Consider alternatives to plants in these sites:

  1. Allow natural processes to proceed, especially if the site’s canopy is evergreen trees. The needles that accumulate over the years form a duff layer that is attractive, prevents loss of water, reduces weed growth, and contributes to the organic matter in the soil over time.  This organic matter allows the soil to hold more water.
  2. Plant at the sunnier edges of woodlands. Woodland edges are very productive in terms of plant growth and support of pollinators and other wildlife.
