Planting Pieris japonica

Pieris japonica is planted in fall or spring for specimens purchased in containers.

  • Planting in fall is, as always, the best way to ensure proper root development, but still it can also be planted up to spring as long as it is well watered.
  • If purchased in containers, it’s still good to plant in spring, simply remember to water more often at the beginning.

Once in the ground, best spread mineral-based mulch around its trunk so as to not influence ground acidity.

Propagating Japanese andromeda

Making cuttings is the easiest and fastest method to propagate your Japanese andromeda.

  • Snip 6-inch (15 cm) cuttings off new growth (only partially hardened off) at the end of summer.
  • Remove lower pairs of leaves, keeping only one or two pair(s) of leaves.
  • If possible, dip the base of the cuttings in powdered rooting hormones.
  • Plant the cuttings in heath soil.
  • Keep the cuttings near light, but not in direct sunlight.
  • Keep substrate a little moist.
  • Protect cuttings from freezing in winter.
  • Transplant in the following spring.

Potted Japanese andromeda

Pieris japonica or Japanese andromeda is a shrub that is particularly well suited to growing in a pot.

Thanks to its reduced breadth, more or less 5 feet (1.5 meters), and its evergreen foliage, it hits the nail to decorate a deck, balcony or terrace and arouses interest in winter, spring, summer and fall.

  • Ensure that the bottom of the pot has a hole in it to avoid stagnating water.
  • Prepare a drainage layer with clay pebbles or small rocks, to make water flow through to the bottom of the pot more easily.
  • Fill the pot exclusively with heath and plant your Japanese andromeda.
  • Mulch with pine bark, it will keep moisture in summer and protect from the cold in winter.
  • Water often from spring to fall, as soon as the surface soil is dry.
