Planting

To start with, plant your Japanese Holly in a space well exposed to the sun. Moreover, the plant thrives in well-drained slightly acidic soil conditions. After spotting the right site, wig a hole of a depth similar to the plant’s root ball, and twice as wide as deep. 

Unpot the Japanese Holly and trim out excess roots that might kill the tree. Put the plant in the hole holding it upwards and fill the roots with soil mixed with well-rotted compost or manure. Stuff back the soil to get rid of any air pockets. Finally, water the plant and tamp down mulch with the organic market to improve water retention.

Watering and nutrients

Young sky Pencils, particularly those less than a year old, thrive in moist conditions. Therefore, it is advisable to water the Japanese Holly weekly during this period. Carefully inspect the soil, and if dry one inch below the hummus, thoroughly water the tree.

Tone down on the supplemental watering once the shrub is well developed and growing well. If your plant is growing in drought-like or dry conditions, maintain regular watering. Additionally, during the spring, you can fertilize your plant with a slow-release fertilizer.

Pollination

During the summer, the Japanese Holly produces tiny white flowers. After pollination, it goes on to produce small black fruits. The sky pencil is a female cultivar. 

This means that the flowers only bear the female plant parts on them. Therefore, the plant can only produce fruits when planted near a Japanese Holly with male flowers. Note that the fruits are not edible and poisonous!

Pruning

Generally, the Sky Pencil maintains its vertical form with minimal assistance and does not require regular pruning. The only time when pruning is needed is when ridding a diseased or broken branch. Also, you can trim the plant to achieve the desired shape or control the height.

Animals, Pests, and Diseases

Common pests that attack the Sky Pencil holly include holly leaf miners, scale insects, and aphids. To control leaf miner infestation, prune out infected branches and treat the plant with an insecticide. As for the aphids and scale, horticultural oil works well.

Japanese Holly diseases include canker. This causes serious damage to the plant’s branches. To control its effects, prune out branches showing sunken areas. During winter, the holly scorch turns leaves to a pale brown color. To avoid this make a habit of planting your Japanese Holly shrub away from strong winds or shelter it with burlap.

Realizing The Best Results

For the potted hollies, unpot them every year and change the soil, and trim down any excess roots for a good garden design.
