Planting & Care

Where to Plant

Sunlight: For the tightest, densest growth, plant your Sky Pencil Holly in full sun, which means at least 6 hours of direct light. It can handle partial shade, but you might notice the vertical branches becoming slightly more open and less "pencil-like" in lower light.
Soil: These hollies thrive in well drained, slightly acidic soil. If you are dealing with heavy clay, mix in organic compost or peat moss at planting time to ensure the roots do not sit in stagnant water.

Watering Requirements

During the first growing season, water your holly deeply two or three times a week to help the root system become established. Mature Sky Pencil Hollies are surprisingly drought tolerant, but inconsistent moisture can lead to "bare legs" where the bottom leaves drop off. Aim for deep, infrequent soakings rather than light daily sprinkles to encourage roots to grow deep into the ground.

Pruning Tips

Because this plant naturally grows in a narrow column, it requires very little pruning. If you need to maintain a specific height or want to tighten up the sides, use bypass pruners in late winter before new growth starts. Think of this like a light haircut to remove any stray branches that have wandered out of the columnar shape, which helps the plant stay sturdy against heavy snow loads.

Fertilizer Needs

Feed your holly in early spring with a slow release fertilizer designed specifically for acid loving evergreens. Avoid applying nitrogen-rich fertilizers in the late summer or early fall. This prevents the plant from producing tender new shoots that would be easily damaged by the first hard freeze of the winter season.

Understanding Our Container Sizes

At Nature Hills, our plants are sold in industry-standard nursery containers. You will notice we use the word "container" rather than "gallon." Container numbers follow a nursery trade size standard, not liquid volume. The number tells you the plant's size category and general maturity level. A larger container means a more established plant with a stronger root system.

Container Sizes

Quart

Plant age: 6 months to 1 year
Best for: Ground covers, perennials, ornamental grasses
What to expect: Our smallest and most affordable size. Well-suited for planting in multiples across a large area. Allow 1 to 2 seasons for full establishment.

#1 Container

Plant age: 1 to 2 years
Best for: Shrubs, perennials, smaller trees
What to expect: About the size of a large coffee can. A well-developed root system in a manageable size. Good value choice when you have time to let the plant grow into the space over a season or two.

#2 Container

Plant age: 2 to 3 years
Best for: Shrubs and trees where you want faster establishment
What to expect: A noticeable step up from a #1 in both plant size and root development. Good choice when you want visible presence without going to a larger size.

#3 Container

Plant age: 3 to 4 years
Best for: Most plants, most situations — flowering trees, shade trees, evergreen shrubs
What to expect: Our most popular size. Strong, developed root system. Plants in a #3 container make an immediate visual impact from day one. If you want a head start rather than waiting seasons for a plant to fill in, this is typically the right choice.

#5 Container and Larger

Plant age: 4 to 5+ years
Best for: Specimen plants, privacy screens, maximum instant impact
What to expect: Large, mature plants ready to make an immediate statement in your landscape. We also carry #7 and larger sizes for select varieties.

Why "Container" and Not "Gallon"?

Nursery container sizes follow an industry trade standard established for the nursery and horticulture industry. The number is a size designation, not a measurement of liquid volume. Actual soil volume varies by plant type, root mass, and growing medium. Using "container" is the accurate industry term. When you see #1, #2, or #3, think of it as the plant's size tier, not a gallon measurement.

Root Pouch Containers

Some Nature Hills plants arrive in a Root Pouch, a breathable fabric container made from 100% recycled materials. Root Pouches encourage denser root development through air pruning, which discourages root circling and promotes a stronger, more fibrous root ball at the time of planting.

There are two types. Knowing which one you have changes how you plant:

Degradable (brown or tan fabric): Plant the entire pouch directly in the ground. The fabric breaks down naturally in the soil over time.
Non-degradable (black or gray fabric): Remove the pouch before planting. Cut the bottom open with scissors, then peel the sides away. The fibrous root ball will hold its shape.

Not sure which type you have? Check the tag on your plant or contact us and we will confirm.

Dramatic upright evergreen! If you need some instant definition or strategic screening in your yard, Sky Pencil Holly (Ilex crenata 'Sky Pencil') works beautifully all year long. It's sure to turn heads wherever you plant one.

No matter how small your yard is or how little planting space is available, there's always room for a Sky Pencil Holly! Just as the name implies, the Sky Pencil Japanese Holly has a pencil-thin growth habit. This dramatic evergreen Holly cultivar creates a very narrow punctuation point anywhere you place it. It reaches up into the sky, creating a tight, column effect. You'll gain a marvelous vertical accent with this easy-care shrub. Dark green elliptic leaves fill out the branches nicely.

How to Use Sky Pencil Holly in the Landscape

Some evergreen shrubs can outgrow their allotted space, but not Sky Pencil. This is a well-behaved, columnar evergreen that can work extremely hard in your garden design and provide year-round greenery.

Another wonderful way to use this special plant is in mass plantings to provide an effective low privacy screen in a narrow side yard or another tight spot. For a solid screen, plant Sky Pencil a bit less than 2 feet apart (measuring from trunk to trunk) The plants will grow together.

Use this screening spacing to hide your garbage cans with style!

For an Instagram-ready modern look, plant them in containers and use them on your patio. Pair with other evergreens, such as Dwarf Alberta Spruce or Blue Arrow Juniper for a lovely, curated collection. Try your hand at the specialized pruning art of topiary.

#ProPlantTips for Care

The Sky Pencil Holly will grow in sun or partial shade, transplants easily, and requires no pruning to maintain its remarkable shape. However, it does adapt well to an occasional trim should you prefer to manage its size. This is the perfect small garden plant or condo patio plant.

It's adapted to a wide range of climates but requires well-drained, slightly acidic soil to perform at its best. Give them full sun and keep the soil moist to keep that beautiful foliage green in color.

Container plants need good water drainage and a consistent water source, plus 3-4 inches of mulch over the top of the soil always helps both potted and in-ground plants. Their root systems won't tolerate poorly drained soils.

In colder hardiness zones, move containers to a protected patio, or unheated garage, an east-facing location out of the sun, or even an unheated garage with a window after the plants have gone dormant in late fall or early winter. Do not let them dry out excessively.

Do you ship Sky Pencil Holly to Alaska, Hawaii, or internationally?
