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
- Bare Root - Cut open the bundle (top and roots are tied) and separate all the plants. Soak roots in buckets of water until planted. Each plant type will be labeled separately for identification. Do not expose the roots to sun. They should never dry out. Keep roots covered. All bare-root plants must be trimmed when planted.
- Containers - Completely saturate all container plants by putting in a larger container of water until stops bubbling, then remove the plant from the container.
Planting Bare Root
- Plant Bare root in spring or fall. A good indicator if you can still plant is if the ground is still workable you’re good to go. If a hard frost is expected be sure to hold off on planting.
- Dig a hole at least 6" wider and the same depth as the root mass. The crown or graft of the plant should be slightly higher than ground level where it was grown at the nursery.
- Trim off the broken roots and branches.
- Place fertilizer packets in hole (if purchased). Do not place other fertilizers in the planting hole. *Use Our Recommended Fertilizer.
- Spread the roots and fill halfway with soil, then water until soil settles completely saturating the soil and planting pit.
- Re-adjust plant and fill the hole with the rest of the soil.
- Back fill the balance of the soil and water well.
- See our link below “Handling & Planting Guidelines” for illustrations on planting.
- 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
- Bare Root - Prune ALL bare root plants to reduce transplant shock and ensure success. Pruning should occur either before or as soon after planting as possible. All pruning should be done with a sharp pruning shears.
- Thin ? to ½ shrub by removing large branches. Top back some branches to improve general shape. Cut the shrub back to at least ½ its original size to promote new growth from the base. See illustrations in our link below “Handling & Planting Guidelines” to help with this process.
- 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.
Planting & Handling Help
Download our Planting and Handling Guide below to plan for a successful arrival and install of your plants. Be sure to water all plants as soon as they arrive and every day until you’re ready to plant. Keep any bare root bundles in a shady, cool spot with the roots covered at all times.
