Growing Conditions Necessary for Planting Sky Pencil Holly

Like any other plant, this elegant-looking shrub has its unique requirements to flourish and enhance the border areas of wide landscapes. Stay along to know the care requirements of this botanical miracle.

  • Watering: When the shrub is young and in its initial growing stage, make sure that you are watering the Pencil Sky plant at regular intervals. 

    Once the species reaches its maturity, it requires watering in moderation, like once or twice a week. Remember to water only when the topsoil is dry, as overwatering can loosen the roots and kill your plant. 

  • Soil Type: One impressive attribute of the Sky Pencil Holly tree is that it can survive in a variety of soil conditions, which makes it the most preferred plant to grow in garden spaces or for outdoor decorations. 

    Though this cultivar usually prefers slightly acidic and well-drained soil types, it can manage to grow in clayey, loamy, or sandy soil, but it should not be too moist. 

  • Sunlight Exposure: Thrives in full sun, the Japanese Holly Sky Pencil requires 6 hours of direct bright sunlight. In warm climatic areas, it is best to keep the plant in partial shade to keep the green-coloured leaves intact. 
  • Pruning Method: While pruning or trimming down the Sky Pencil Holly, do not forget to maintain its narrow pencil-like structure. Remove the extra branches or dead foliage but avoid flat topping the tree. The best time to prune your Sky Holly is during late winter or early spring when new growth begins.
  • Propagation Technique: Propagating Pencil Hollies is a quite straightforward process. Cut approximately 4-6 inches long healthy stem, apply the rooting hormone, and plant the stem in a container having a well-composed soil mix, and you are good to go! 

With proper care, Sky Japanese Pencil Holly can grow into strong and healthy evergreen shrubs. The little to no maintenance of this species makes it a perfect choice for both experienced and new gardeners.
