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.

Gorgeous!

The plants arrived in perfect shape, and started blooming immediately. I just hope they winter well and are as beautiful next spring!

Hi Morgaine,

Thank you so much for sharing your wonderful feedback! We're thrilled to hear your plants arrived in perfect condition and that they started blooming right away—it truly sounds like you have a thriving garden in the making. As you look ahead to winter, planting care can make all the difference. We recommend mulching around the base to protect roots from freezing and ensuring your plants receive adequate water before the ground hardens. If you’re growing species specific to cold climates, they often handle winters beautifully; for others, some extra insulation or bringing potted plants indoors can be helpful. Feel free to reach out anytime—we’re here to support you through all the seasons!

To greener days ahead,

Frequently Asked Questions

How big does the Coral Knock Out® Shrub Rose get at maturity?

The Coral Knock Out® Shrub Rose typically reaches 3-4 feet tall and wide at maturity. This compact size makes it perfect for borders, foundation plantings, or accent spots. Allow adequate spacing for air circulation and plan for its full spread when planting.

What are the basic care requirements for Coral Knock Out® Shrub Rose, like sun and soil?

Coral Knock Out® thrives in USDA zones 5-11 with excellent heat tolerance. This hardy rose prefers full sun and well-draining soil for continuous blooms from spring through first frost. Plant in amended soil and water regularly the first year to establish strong roots.

Does the Coral Knock Out® Rose need pruning, and when?

Coral Knock Out® Roses benefit from light pruning in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches and trim back by about one-third to maintain shape. In zones 5-11, prune after the last hard frost to encourage vigorous blooming through fall.

Is the Coral Knock Out® Shrub Rose disease-resistant, especially to black spot?

Knock Out® Roses are bred for excellent disease resistance, including strong resistance to black spot, powdery mildew, and rust. This makes them incredibly low-maintenance compared to traditional roses. Plant in zones 5-11 with good air circulation for best results.

How much water does the Coral Knock Out® Rose need after planting?

Water newly planted Coral Knock Out® Roses deeply 2-3 times per week for the first month. Once established, these hardy shrubs (zones 5-11) are quite drought tolerant and need watering only during dry spells. Check soil moisture by inserting your finger 2 inches deep before watering.

Will the Coral Knock Out® Shrub Rose bloom all season long, from spring to fall?

Yes, Coral Knock Out® blooms continuously from spring through fall until the first frost. This reliable performer produces abundant pink-orange blossoms all season long in zones 5-11. Plant in full sun for best flowering performance.

Are the plants shipped potted or bare-root for Coral Knock Out® Shrub Rose?

Coral Knock Out® roses are typically shipped as potted plants during the growing season. This gives you an established root system that transplants easily in zones 5-11. Plant in spring after last frost for best establishment and blooms through fall.

What is the condition of Coral Knock Out® roses upon arrival from shipping?

Coral Knock Out® roses arrive as healthy, dormant bare-root plants or potted nursery stock ready for planting. They're hardy in zones 5-11 and establish quickly once planted. Plant immediately upon arrival for best results, or keep potted plants watered until you can get them in the ground.

What fertilizer, if any, does the Coral Knock Out® Shrub Rose need?

Coral Knock Out® roses are relatively low-maintenance and don't require heavy feeding like traditional roses. A balanced, slow-release fertilizer applied in early spring works well for zones 5-11. Feed once more in mid-summer to support continuous blooming through fall frost.
