Although the Japanese holly belongs to the same plant genus as the European holly, it differs significantly from it. Visually, it is more similar to the native boxwood, which is often planted as a hedge, and is also used in a similar way.

During the flowering period, the Japanese holly should not be fertilized

Plant the Japanese holly

While Japanese holly tolerates partial shade, it grows much denser in the sun. She also likes to be sheltered from the wind. The Japanese holly likes the soil a bit acidic rather than alkaline. It can also be slightly damp.

The Japanese holly is only partially hardy and should be well protected from frost in winter, for example with a thick layer of leaves and/or brushwood. Black berries develop from the pale white flowers in autumn. Unfortunately, these berries are poisonous.

Water and fertilize the Japanese holly

The Japanese holly needs plenty of water because it has very sensitive roots that are easily damaged by drought. It tolerates rainwater best, as this does not contain lime. If there is no rainwater available for watering, let the tap water stand a little.

Fertilize your Japanese holly with a commercial liquid fertilizer about every three to four weeks during the summer months. In winter and during the flowering period, Japanese holly does not require fertilizer.

Propagating the Japanese holly

Japanese holly can be propagated by seed or by cuttings. Sowing, however, is quite a lengthy affair. Cuttings are therefore recommended for impatient gardeners. July or August, when the plant is still in full sap, is a good time for this type of propagation. By the way, you can also grow the Japanese holly as a bonsai.

The essentials in brief:

  • grows slowly
  • needs rather acidic soil
  • prefers a sunny and sheltered location
  • water regularly
  • fertilize regularly in summer
  • only conditionally hardy
  • Propagation by sticks or seeds
  • Berries are poisonous!

tips

The Japanese holly is an excellent hedge plant and can very well be planted in place of the box tree infested with the box tree moth.
