Petite Knock Out® Rose

Rosa 'meibenbino' PP30811, US Utility PPAF

Petite Knock Out® is what I recommend when you want the famous Knock Out® reliability, but you need it in a smaller, neater package—something that edges a bed, lines a walk, or shines in a container without taking over. The red blooms keep coming for months, the plant stays naturally tidy, and it rewards the basics: full sun, base watering, and one good prune before spring growth takes off.

Petite Knock Out® Rose for Compact Red Color, Easy Borders, and Season-Long Blooms

Dwarf Size With True Knock Out® Bloom Power

Petite Knock Out® Rose is the rose for gardeners who want the famous Knock Out® performance—without the full-size shrub footprint. It stays naturally compact and rounded, making it a perfect fit for smaller beds, townhouse landscapes, and front-yard borders where every inch matters. You get a tidy little mound that looks intentional, not “stuffed in,” and it still delivers a steady parade of flowers that keeps the planting looking lively.

Because it’s compact, it’s also easier to design with. Use it to echo color along a walkway, frame a foundation bed, or tuck into mixed borders where taller shrubs would overwhelm the space. If you love the idea of a rose hedge but don’t want something tall and bulky, Petite Knock Out® gives you a low, flower-forward edge that reads clean and modern.

Red Blooms That Keep Coming From Spring Through Frost

This rose is built for long-season color. Petite Knock Out® blooms from spring through frost in repeated waves, giving you that “always flowering” look that makes landscapes feel finished. The blooms are typically a vivid red, and the plant produces them generously across the canopy so the color is easy to see—whether you’re standing at the curb or enjoying the bed up close.

Deadheading isn’t required for the plant to keep blooming, which is a major win for low-maintenance gardening. If you like a super-polished look, you can snip off spent clusters now and then, but the point of Petite Knock Out® is that it performs even when life is busy. Give it sun, steady water while establishing, and a little seasonal shaping, and it will keep your borders colorful for months.

A Perfect Choice For Edging, Mass Plantings, And Containers

Petite Knock Out® Rose typically matures to about 18 inches tall and 18 inches wide, making it a standout for edging and front-of-bed placement. It’s a natural along paths and driveways, where you want a low plant that won’t block sight lines but still delivers real floral impact. It also shines in mass plantings—think a ribbon of red that stays uniform and tidy instead of turning into a tangled, uneven line.

This compact habit also makes it a strong container rose. Use it in a large pot on a sunny patio to bring rose color close to where you sit, or combine it with complementary plants for a seasonal mixed container. Just remember that pots dry faster than beds, so container roses need a little more attention to watering during summer heat to keep bloom performance strong.

Cleaner Foliage With Disease Resistance And Simple Watering Habits

Knock Out® roses are known for strong disease resistance, and Petite Knock Out® carries that same reputation when it’s planted well. Full sun and good airflow help the foliage dry quickly after rain or irrigation, supporting cleaner leaves throughout the growing season. Watering at the base (instead of spraying overhead) is one of the simplest ways to keep the plant looking fresh and healthy.

A straightforward routine keeps this rose at its best: mulch to stabilize soil moisture (kept off the base), deep watering during establishment, and a once-a-year prune to refresh growth and encourage new bloom-producing stems. The result is a compact rose that looks “professionally landscaped” with a homeowner-friendly level of effort—steady blooms, tidy form, and fewer headaches.

How to Care for Petite Knock Out® Rose

Be sure to read our planting instructions to ensure a healthy and happy Petite Knock Out® Rose plant for years to come!

How should I plant Petite Knock Out® Rose?

How should I plant Petite Knock Out® Rose?

Plant Petite Knock Out® Rose in full sun in well-drained soil. Dig a hole about twice as wide as the root ball and set the plant so the top of the root ball sits level with the surrounding soil. Backfill with native soil, water deeply to settle, and create a shallow watering ring to guide water into the root zone. Mulch 2–3 inches over the root area to conserve moisture and reduce weeds, keeping mulch a few inches away from the base of the plant. Because this is a compact rose often used in borders, take time to space plants evenly for a clean line and good airflow. A sunny, well-drained start is the fastest path to heavier bloom cycles and cleaner foliage.

How often should I water Petite Knock Out® Rose after planting?

How often should I water Petite Knock Out® Rose after planting?

Water deeply right after planting, then keep the root zone evenly moist (not soggy) for the first several weeks. A good baseline is a deep soak about once per week, increasing to twice per week during hot weather, sandy soil, or windy conditions. After it’s established, water during extended dry spells and during heavy bloom periods for best performance. Water at the base rather than overhead so foliage stays drier. If you’re growing it in containers, plan on watering more frequently since pots dry out faster than garden beds.

When should I fertilize Petite Knock Out® Rose?

When should I fertilize Petite Knock Out® Rose?

Fertilize in early spring as new growth begins, using a rose fertilizer or a balanced slow-release fertilizer. Apply it over the root zone (not against the stems) and water afterward so nutrients move into the soil where feeder roots can absorb them. If you want extra bloom power, feed again after the first major flush of blooms. Avoid heavy late-season fertilizing, which can push tender growth when the plant should be slowing down. Consistent, moderate feeding supports better bloom cycles and a fuller, denser mound.

When and how should I prune Petite Knock Out® Rose?

When and how should I prune Petite Knock Out® Rose?

Prune Petite Knock Out® Rose in late winter or early spring before active growth begins. Remove dead or damaged stems first, then lightly cut the plant back to refresh its shape and encourage vigorous new growth that will flower heavily. Because it’s naturally compact, you typically don’t need aggressive pruning—think “shape and refresh,” not “hard renovation.” During the season, you can lightly trim straggly growth to keep the mound neat, but avoid heavy pruning in extreme heat. A simple yearly prune is usually all it needs to stay dense and bloom-packed.
