Planting And Caring For Sky Pencil Holly
The Sky Pencil holly is a beautiful plant that requires careful consideration for successful growth and long-term health. Here are some key factors to keep in mind:
- Sunlight: Choose a spot that receives ample sunlight throughout the day as the plant thrives in full sun.
- Soil: The holly prefers slightly acidic soil that is well-draining. Take this into account when selecting the planting location.
- Planting Hole: Dig a hole that is twice the width and depth of the plant’s root ball. This will provide enough room for the roots to spread and establish themselves.
During the first year of growth, it is crucial to water the Sky Pencil holly on a weekly basis. This helps establish a strong root system and promotes healthy development. However, as the plant matures and becomes established, supplemental watering can be reduced, as the holly is resilient and can tolerate some drought.
Fertilize the plant in the spring with a slow-release fertilizer to provide the necessary nutrients for optimal growth and vitality. Follow the instructions on the fertilizer packaging for proper application rates. If pollinated, the Sky Pencil holly will reward you with small white flowers in the summer and black fruits in the fall.
While pruning is not necessary for the health and growth of the Sky Pencil holly, occasional trimming may be required to maintain its desired shape or control its height. However, it’s important to note that this shrub is best left to grow naturally to showcase its unique form and slender silhouette.

Frequently Asked Questions
How long does holly take to grow?
Holly, unlike other fast-growing evergreen shrubs, takes significantly longer to reach maturity. It requires a patient approach, as it can take approximately 20 to 25 years for a Holly shrub or tree to reach its full size. While this slow growth may be seen as a disadvantage by some, it also offers unique advantages, such as the opportunity for caretakers to observe and appreciate the gradual development of the plant over time.
How quickly does Japanese holly grow?
Japanese holly, known for its compact form, possesses a notably slow growth rate. Growing at a rate of fewer than 6 inches per year, it takes its time to reach its mature height and width of 4-5 feet if left unpruned. These hollies can thrive in partial shade or full sun environments and are content with a consistently moist soil, although waterlogged conditions should be avoided.
Why is my sky pencil holly dying?
Your Sky Pencil holly may be dying due to its poor adaptation to the climate in south Louisiana. Being a cultivar of Japanese holly, it is susceptible to root rot, which is common in the hot summer months. Excessive irrigation or heavy rainfall can further exacerbate this issue, and given the abundant rainfall this summer, it is likely a contributing factor to the decline of your plant.
Do sky pencil holly bloom?
Yes, the Sky Pencil Holly does bloom. In late spring, it produces small and delicate white flowers with four petals. These blooms add a touch of beauty to its dense and dark green foliage. As the flowers are pollinated, black rounded fruits begin to appear in the fall, further enhancing the visual appeal of this elegant plant.
