Russian sage can be transplanted at any point during the growth season. It grows well in full sun with well-draining soil that’s slightly dry or has medium moisture. Pruning in the spring can help minimize flopping, which is a problem when Russian sage is grown in areas with less than eight hours of direct sunlight per day.
Is it simple to transplant Russian sage?
The faded flowers will still provide interest and color to the winter landscape if you choose not to trim the bushes back.
It might be challenging to transplant established Russian sage. With as much soil and the plant’s root system as you can, dig a wide circle around the plant. After transplanting, the plant will probably experience shock, from which it may take several months to recover. Early spring is the ideal time to move Russian sage. In the coldest areas, wait until the earth is warm. Before transferring the plant, trim the stems back by two-thirds. Until you notice new growth, keep the transplant well-watered; after that, gradually reduce water.
Can you divide a Russian Sage?
Russian sage plants require very little watering maintenance. In actuality, once established, Russian sage does well in dry soil and requires little water.
Every other year in the late fall, scatter a spoonful of all-purpose fertilizer or a shovelful of compost around each plant.
Provide a 2-inch (5-cm) coating of pine needles over the winter in areas north of USDA Zone 6 and remove them in the spring when new growth appears.
While leaving the stems and seed pods in the garden until spring adds winter interest, you can trim the stems back to a foot (.5 m) above the ground for a neater appearance.
Pruning is the main part of Russian sage care in the spring and summer. Cut the old stems back to just above the lowest tier of leaves when the new spring growth appears. Shear off the top one-third of the stems if the plant starts to sprawl or spread open in late spring or summer to promote upright growth. If the plant stops blooming in the summer, cut off the top half of the stems. This promotes new growth and a fresh blooming cycle.
By splitting the clumps or taking cuttings in the spring, you can propagate Russian sage plants. Every four to six years, divide the clumps to revitalize the plants and limit their expansion.
How is Russian sage dug up?
Russian sage (Perovskia atriplicifolia), a hardy, tenacious perennial, is known for flourishing in conditions when no other plants will. This semi-woody Afghan shrub can withstand drought and is resistant to disease. It can live in poor soil, performs well in direct, hot sunlight, and has few insect predators. Thanks to its lacy silver-gray foliage and delicate spires of light purple blossoms, the plant is frequently seen in U.S. Department of Agriculture plant hardiness zones 4 to 9, where it is utilized to line garden borders and as substantial accent plants. In a flowerbed or small garden, Russian sage plants can quickly become invasive due to widespread sucker growth, so you might need to occasionally remove them.
Overwatering your Russian sage plant will cause root rot and poor health. Russian sage performs badly in muddy, poorly drained soil and eventually perishes from winter-kill. You can remove the plant’s stump after it dies from your garden.
Simply dig the plant out of the ground by cutting it back to the stump. Pull out the root system after moistening the soil surrounding the stump to make it more pliable. If you throw away the roots in the garbage rather than your compost pile, the plant can start to grow again.
Use a herbicide that contains prodiamine to treat the plant and destroy it. Before the Russian sage blooms in the middle of the summer, spray the herbicide on the plant’s leaves.
If any sucker offshoots appear where your Russian sage originally grew, remove them. Manually remove the suckers, then dispose of them in the trash. Apply herbicide to the ground area where suckers are a problem.
In the fall, should Russian sage be pruned?
The growth from the previous year might continue throughout the spring in regions with moderate winters. In colder regions, chilling weather kills back the top growth. Cut the stems down to 12 inches above the ground in the early spring when the buds on the stems are starting to swell in order to promote new growth from the ground level for the upcoming season.
According to Arbor Valley Nursery, pruning plants in the fall could promote early growth that is vulnerable to frost damage. Rejuvenate plants as they get older over a few years by cutting some of the older stems to the ground. Consider lifting and dividing a plant in the early spring and replanting the divisions if it grows congested over time. For terminal branching and increased bloom production, Russian sage can also benefit from mild pruning in the early summer.
Must Russian Sage be Reduced?
For us on Nantucket, Russian sage is an excellent plant because it possesses all the characteristics we value in a superb perennial:
- It is resilient and requires little particular care from the gardener to overwinter.
- Most of us on the island have a lean, sandy soil, which is where it operates best.
- Its fragrant, gray-green leaves has just the right amount of fuzz to be particularly deer resistant.
- It has a lengthy interest season, looking fantastic from June through October.
- When seasonal people are present on the island in the middle to late summer, it blooms for a very long time.
- It is extremely adaptable in the environment thanks to its lacy leaves, blue flowers, and open habit. It works well with decorative grasses, can be added to perennial gardens, and creates a striking mass planting.
I’ve also had great success pruning Russian sage in the fall when I take down my spent perennials, even though many of us have been trained to leave it standing and prune it in the spring. Wait until it is dormant, preferably after a frost, but be sure to do so.
Russian Sage should be pruned with the following goals in mind: Removing dead twigs, cutting off broken or damaged branches, and encouraging vigorous growth from a healthy foundation of stems that will bloom the next summer.
To prune Russian Sage while it’s dormant, adhere to these steps:
- Trim back all previous growth to healthy buds within 6 to 8 inches of the ground.
- Remove any damaged or broken timber as well as any dead branches.
- Remove any weak branches that won’t be able to sustain robust new ones the next season.
- In order to encourage strong, new shoots to replace the older ones, prune a couple of the oldest stems close to the soil, if possible.
I’ll share a small secret with you now that we are aware of how to prune Russian sage properly. The “Hair Cut method of pruning” is used by the majority of island landscapers because of how forgiving this plant is. Simply grab the twigs in one hand and use the other to cut them all off evenly. Or, if you’d rather, use your hedge trimmers to attack them! Any remaining dead twigs will be rapidly buried by new growth next summer.
When should Russian sage be transplanted?
Any period during the growth season is suitable for transplanting Russian sage, also known by the scientific name Perovskia atriplicifolia. This perennial grows best in full sun and well-draining soil that is dry or moderately damp in U.S. Department of Agriculture plant hardiness zones 5 through 9.
Are the roots of Russian sage invasive?
Many gardeners are on the hunt for plants that can not only survive in dry, poor soils, but also thrive there in an effort to create environmentally friendly landscapes that require the least amount of maintenance. Given all that it contributes to the landscape in terms of color, texture, pollinators, and presence, Russian sage ought to rank quite close to the top of that list. Although it is not a native plant, if you give it the well-drained conditions it requires, it won’t spread quickly and will remain where you plant it for many years.
How is Russian sage kept in a compact form?
Russian sage is a fuss-free perennial that adds color all season long and is drought resistant. With a modest 28- to 32-inch height, “Denim ‘n Lace” manages the towering and floppy growth of classic Russian sage. Plants that are fully colored resemble lavender. In Zones 4–9, hardy. Perovskia atriplicifolia ‘Denim ‘n Lace’ is its botanical name.
Pruning Russian sage requires courage. Russian sage pruning can be intimidating at first, but once you get the hang of it, your plants will become stronger and fuller and put up a more attractive flower display. Although taking tip cuttings may qualify as a pruning action by genuine botanists, pruning is not a part of the propagation of Russian sage.
Russian sage is normally pruned by the regular gardener at the beginning and end of the growth season. With its purple flower spires, Russian sage creates a purple haze in gardens starting in mid- to late summer. The silver-gray stems are encircled by whorls of the fuzzy blossoms, creating an intriguing sight. Plantings are given a great dramatic flair by foot-long flower heads. Pruning Russian sage in the spring properly paves the way for a stunning flower display.
Russian sage’s stems change from being green, soft, and succulent to having a woody component as it ages throughout the growing season. This kind of perennial flower is referred to by gardeners as a semi-woody perennial or shrubby perennial. Russian sage stems should be cut back to 18 inches at the end of the flowering season in cold climates, when the blooms have faded and a deadly frost has occurred. For a more interesting winter garden view, skip the pruning and leave the stems alone. In the coldest regions where Russian sage is hardy, it is good to leave stems in place. zone 4 and zone 5.
Stems freeze as winter approaches and subfreezing temperatures take hold. Depending on how cold it gets and how long it lasts, stems may or may not freeze to the point of death. Russian sage has two sites where new growth appears in the spring: the stems and the plant’s crown, which is where the stem tissue and roots converge. Typically, the crown is hardly visible above ground.
On Russian sage, a harsh winter may kill all of the aboveground stems, and only the crown produces new growth. Stems may only partially die back during milder winters. In this situation, the Russian sage would produce new growth from both the stems and the crown.
Snip stems back to 12 to 18 inches as springtime approaches. Leave 18 inches in place if you’re cleaning up your garden well before the last average frost date. Cut stems down to 12 inches or less if there is no longer any risk of frost.
Zones 4 to 9 are hardy for Russian sage. It might not die back significantly, if at all, throughout the winter in warmer areas. After the blossoms have faded and when winter has arrived, Russian sage should be pruned in regions with mild winters. If you don’t want to see stems throughout the winter, you can give them a severe pruning now, trimming them to a height of 6 to 12 inches. Otherwise, wait until very early spring or late winter to perform a rigorous pruning.
Pruning Russian sage right after after flowering in regions with lengthy growing seasons might encourage a second flush of bloom. Reduce plant growth by 50% to promote reblooming.
What’s causing my Russian sage to collapse?
I have two different varieties of three Russian sage plants planted in medium to full light. They range in age from 2 to 4. They will not get upright and will flop along the ground. Years ago, I had a Russian sage who behaved in a similar manner. Why am I misusing this?
Once it has grown to the majority of its regular height in the middle of the season, Russian sage can flop. When there is just partial sun, the plant may “extend a little, looking for the sun.” Such uncontrolled growth can make the stems top-heavy and eventually flop.
When possible, give the plants a full day of sunlight. Typically, 8 hours is ideal. Once they are established, they can withstand droughts as well. They typically prefer to stay a little shorter and more compact and are better able to support themselves erect if kept warmer and dryer.
There are supports that are a ring with a grid inside of it. This grid will be partially obscured by the plants as they expand as they grow through it. Therefore, consider using one of these supports or even a standard peony ring if the plants of Russian sage are still flopping over after you have given them as much sun as you can.
Does Russian sage like shade or the sun?
Russian sage grows best in hot, dry climates with well-draining soil. Pick a location that receives 6–8 hours of direct sunlight. Plants should be placed 2-3 feet apart using these methods.
- Dig a hole that is slightly broader and deeper than the root ball after loosening the dirt in the planting location.
- Lick up the soil surrounding the plant’s roots after removing it from the nursery pot.
- The crown of the plant should be level with the earth when it is placed in the hole.
- To get rid of air pockets, backfill the hole with soil and lightly tamp it down.
- Water wisely.
Russian sage may grow in a variety of soils, although it favors ordinary to lean soil with a pH that is slightly alkaline. When the soil is overly rich, plants may fail. Ensure that there is enough drainage to stop root rot. Use an exceptional all-purpose potting mix for your containers.
Watering: Once established, Russian sage is drought tolerant and favors medium to dry soil. Disease and root rot may result from overwatering. To promote a deep root system throughout the first growth season, water frequently.
Russian sage requires little to no additional fertilizer. Compost can be used as light mulch in the spring, if desired.
Staking: Larger plants have a tendency to floppiness. Plants may tilt or collapse due to a lack of light or an excessively rich soil environment. Staple any stalks that are sagging. Plant in groups or with other plants for support to prevent flopping.
