Planting & Care for Shrub Roses
- Roses may be mass-planted in beds and borders or planted alone in the garden.
- The hardiness of roses is variable.
- Many tolerate extreme cold while others can be singled by frost.
- To form stocky shots and flower bounteously, roses need full sun all day.
- Good air circulation is important, but shelter from strong wind to avoid flower damage.
- Rose shrubs prefer heavy but well-drained, humus-rich loamy soils.
- 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 in a larger container of water until stops bubbling, then remove the plant from the container.
- Shrub roses can be planted March-November.
- Dig a hole no deeper than the depth of the container and 6" or more wider on the sides.
- Slide plant from pot by tapping on the bottom of the pot.
- With shovel or knife trim bottom 2" off of 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
- Back-fill the hole with soil, making sure 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.
- Water frequently when newly planted.
Pruning - After Planting
- Containers - Although it is not essential for container plants to be pruned after planting, a light pruning to remove any broken branches during shipment and improve shape will help the looks of your new planting.
Pruning - Through-out the Season
- Tackle pruning in early spring before buds burst. Typically this is around March-April.
- In fall, shorten extra-long stems on bush roses to avoid them catching the wind and loosening the stem.
- Always cut to just above a bud.
- Deadhead all roses weekly to channel energy into new shoots and more flowers.
Watering - After Planting
- Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as oft en as every 2-4 days at the start and at least a minimum of once per week.
- Beyond the 6 week establishment period, water once per week, unless rains occur.
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 is dry, give it a good soaking with the hose end (no nozzle) watering the soil only, not the leaves.
