Planting & Care for Petite Knock Out® Shrub Roses
Preparation
- Dwarf Knock Out Roses may be mass-planted in beds and borders or planted alone in the garden.
- The hardiness of roses is variable.
- Most of these mini Knock Out roses tolerate extreme cold, while others can be singled by frost.
- To form stocky shots and flower bounteously, rose blooms need full sun all day.
Good air circulation is important, but shelter from strong wind to avoid flower damage. - Rose shrubs prefer heavy but humus-rich, well-drained soil.
- You can improve light, sandy, gravelly, or chalky soils by adding large amounts of well-rotted manure or decomposed garden compost several weeks before planting.
- Add garden lime to highly acidic soils.
Opening Plant Material
- Containers: Completely saturate all container plants by putting them in a larger water container until bubbling stops. Remove the plant, then dig a hole no deeper than the depth of the container, ensuring it’s wider on the sides by an additional 6” or more.
Planting Containers
- Shrub roses can be planted from March to November.
- Dig a hole no deeper than the depth of the container and 6" or wider on the sides.
Slide the plant from the pot by tapping on the bottom of the pot. - With a shovel or knife, trim the bottom 2" off the root ball for plants in plastic containers.
- Rotate the plant to the proper position. Never lift or move plants by the tops.
Place the root ball in the hole. - Adjust the plant height so the root crown is slightly higher than the ground.
Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer. - Backfill the hole with soil, ensuring the top of the root ball is visible and slightly higher than the soil around it.
- Firm the soil around the plant. Water well to settle soil around the root ball.
Pruning - After Planting
- Containers: Although it’s not essential after planting, light pruning can help shape a Petite Knockout rose. Doing so removes any broken branches from shipping or thins out a heavily branched plant to assist in the transplanting process and the appearance of your new planting.
Pruning - Through-out the Season
- Perform pruning in early spring before buds burst, typically around March-April.
- In fall, shorten extra-long stems on bush rose blooms to avoid them catching the wind and loosening the stem.
- Always cut to just above a bud.
- Deadhead all rose blooms weekly to channel energy into new shoots and more blooms.
Watering - After Planting
- Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as often as every 2-4 days at the start and at least a minimum of once per week.
- Beyond the six-week establishment period, water once per week unless rain occurs.
- Remember to check soil moisture by sticking your finger into the soil around 3”.
Watering - Through-out the Season
- After the first season, plants should only be watered during extended periods without rain.
- How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it’s dry, give it a good soak with the hose end (no nozzle), watering the soil only, not the leaves.
- Same as after planting, stick your finger into the soil around 3” to check soil moisture.
