Planting & Care

Where to Plant

Sunlight: This variety thrives in partial shade to full shade. While it handles more sun in northern climates, afternoon shade is best in hotter regions to prevent the dark green foliage from bronzing or scorching.
Soil: Use moist, well-drained soil with a neutral to slightly alkaline pH. If you are dealing with heavy clay, plant it in a slightly raised mound or "berm" to ensure the shallow roots never sit in stagnant water.

Watering Requirements

During the first two growing seasons, keep the soil consistently moist like a wrung out sponge to support root establishment. Mature plants are remarkably drought tolerant, but you should still provide a deep soaking during extended dry spells to prevent stress and leaf drop. Always water at the base of the plant in the morning so the foliage dries quickly, which is the best way to prevent fungal issues like boxwood blight.

Pruning Tips

This slow growing shrub stays naturally low, so you only need to perform a light "haircut" in early spring before the first flush of growth. Use hand pruners to thin out a few of the oldest inner branches to improve air circulation and light penetration to the center. This technique keeps the interior foliage healthy and prevents the plant from becoming a humid environment where pests like to hide.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring as you see the buds begin to swell. Avoid using high nitrogen fertilizers late in the summer or early fall. Doing so forces the plant to produce tender new leaves that will not have enough time to harden off before the first hard freeze, leading to significant winter dieback.

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.

Frequently Asked Questions

How should I care for Flat-tery™ Boxwood, including pruning and watering?

Flat-tery™ Boxwood requires minimal care once established and tolerates drought well. Water regularly the first year, then only during extended dry periods. Prune lightly in late winter if needed to maintain shape, though its natural spreading habit rarely requires trimming.

Is Flat-tery™ Boxwood hardy in winter, and does it suffer from winter burn?

Flat-tery™ Boxwood is cold hardy through USDA zones 4-9 and retains its glossy green foliage all winter without winter burn issues. Its low, spreading habit actually protects it from harsh winter winds better than upright varieties. Shop at Nature Hills for this reliable four-season performer.

When is the best time to plant Flat-tery™ Boxwood?

The best time to plant Flat-tery™ Boxwood is early spring or fall when temperatures are moderate. In zones 4-9, spring planting allows the roots to establish before summer heat, while fall planting takes advantage of cooler weather and winter root development.

Is Flat-tery™ Boxwood deer-resistant or prone to pests like leafminers?

Flat-tery™ Boxwood is naturally deer and pest resistant, making it a reliable low-maintenance choice. Boxwoods are generally unappealing to deer and rabbits due to their dense, waxy foliage. Plant it in zones 4-9 for best pest resistance and minimal upkeep once established.

Can Flat-tery™ Boxwood be used as a groundcover, and how wide does it spread?

Yes, Flat-tery™ Boxwood makes excellent groundcover, spreading 3-4 feet wide while staying just 1-2 feet tall. Its naturally spreading habit eliminates the need for constant pruning. Plant on 3-foot centers for solid coverage in zones 4-9, available at naturehills.com.
