Planting & Care

Where to Plant

Sunlight: Aim for a location that receives at least four to six hours of direct sun daily. Full sun encourages the most compact, dense growth, which is what you want for formal hedging. Partial shade is acceptable, but the foliage density may be slightly reduced, making the plant a bit more open.
Soil: This shrub is adaptable but absolutely demands well-drained soil. If you have heavy clay, spend time working in ample organic matter like compost and possibly some coarse grit or expanded shale to ensure water moves freely; Boxwood roots hate sitting in standing moisture. It prefers a slightly acidic to neutral pH.

Watering Requirements

During its first season, water your Boxwood deeply two to three times per week, especially during summer heat, until the root system is established. Once mature, the Calgary Boxwood is quite drought tolerant, but it benefits from a slow, deep soaking every few weeks during prolonged dry spells. Inconsistent watering will stress the plant, causing the leaves to become smaller and potentially leading to foliage bronzing or dull color. Remember to give it a thorough drink before the ground freezes in late fall to prevent winter burn.

Pruning Tips

The goal of pruning Boxwood is to maintain its dense shape and encourage healthy internal air circulation. This plant primarily produces new foliage on new wood. The best time for shaping is in late winter or early spring before the new growth flush begins. For highly formal hedges, you can give it a very light, corrective shear in late spring or early summer after the initial growth has matured. Critically, avoid any heavy pruning after mid-August; cutting back too late will stimulate soft new growth that will not have time to harden off before frost, leading to severe winter tip damage.

Fertilizer Needs

Apply a slow-release, balanced granular fertilizer, like a 10-10-10, or a fertilizer formulated for acid-loving shrubs (like Holly-tone) in early spring, right as the new growth starts. This provides the season’s essential nutrients. What to avoid: Do not feed your Boxwood with high-nitrogen fertilizer after mid-July. This late-season feeding encourages soft, late-season growth that is extremely susceptible to frost damage and dieback, negating your hard work.

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.

Planting:

Choose a site with full sun to partial shade.
Use well-drained soil; amend with organic matter if needed.
Space plants 2–3 feet apart for seamless hedges.

Care:

Water regularly during the first growing season to establish roots. Ensure that your shrubs receive adequate water in late fall. Moisture in their leaves will protect your evergreens against drying winter winds and windburn.
Fertilize in early spring with a balanced fertilizer.
Prune or shear lightly in late winter or early spring to shape and remove dead or damaged growth. These are naturally dwarfed shrubs that will remain small. They can be easily sheared into tight, upright ovals.
Mulch around the base to retain moisture and regulate soil temperature.
