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.
In the fall, may I transfer Russian sage?
Russian Sage Transfer Time. Russian sage can be transplanted at any point during the growth season. It thrives in full sun and well-draining soil that is either slightly dry or moderately damp.
When is Russian Sage splittable?
The drought-tolerant Russian Sage (Perovskia atriplicifolia) has lovely silvery-gray foliage. Russian sage blooms along its long stalks in late summer, creating billowing clouds of small lavender flowers. Although Russian sage prefers warm sunlight, it may also survive in regions with extremely chilly winters. Russian sage can be challenging to divide and prefers to be left alone, but successful division is frequently feasible. Russian sage can take a while to establish itself, so be patient. However, Russian sage is a hardy plant that will endure in your yard for many years once it is established.
When the plants are young in the spring, divide Russian sage. To prevent the roots from drying out too quickly and to give the newly divided plant time to settle in its new place, pick a chilly morning on a cloudy day.
- The drought-tolerant Russian Sage (Perovskia atriplicifolia) has lovely silvery-gray foliage.
- Although Russian sage prefers warm sunlight, it may also survive in regions with extremely chilly winters.
With pruners or kitchen shears, remove only approximately 3 to 4 inches of the Russian sage cluster. With a shovel, dig the Russian sage cluster. If the Russian sage clump is big, cut off a smaller portion of it with the edge of your shovel and leave the rest of the plant in the ground.
Shake the Russian sage plant carefully to shake off extra soil as you lift the cluster from the ground. As you divide the clump into smaller pieces, carefully pry the roots away with your fingertips. The size of each division should allow for four or five shoots, with multiple strong roots on each shoot.
With a shovel or trowel, dig a hole for each division, then plant the freshly divided Russian sage in a bright area of your yard. Each plant should be spaced at least 18 inches apart.
- With pruners or kitchen shears, remove only approximately 3 to 4 inches of the Russian sage cluster.
- If the Russian sage clump is big, cut off a smaller portion of it with the edge of your shovel and leave the rest of the plant in the ground.
For the first growing season, water the Russian sage right away and keep the soil evenly moist. After the first growing season, Russian sage can withstand dryness and only sometimes has to be watered in hot, dry weather. Avoid overwatering the Russian sage since too much moisture can make it decay.
You can also plant divisions of Russian sage in patio pots. Select a container with a hole at the bottom, and then fill it with potting soil from a store. At the same soil depth as when it was first planted, place the Russian sage in the container. For the first growth season, keep the soil moist but avoid overwatering.
Should the amount of 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 ought my Russian sage to be chopped down?
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.
How is Russian sage prepared for winter?
Russian sage is a hardy perennial herb that thrives in Northern California’s temperate climate with the right fall maintenance and minimal winter protection. Autumn brings forth the bluish-lavender blooms, which draw butterflies and bees to the yard. The plant’s erect shape and silvery stems, which mature to heights of 3 to 5 feet, provide appeal to the home landscape even in the winter. Although Russian sage does nicely in a flower bed with a variety of flowers, it thrives in areas with dry, poor soil and rock gardens.
Mulch should be uniformly distributed 2 to 3 inches around the Russian sage plants. Mulch aids in retaining soil moisture and ensuring a constant soil temperature. Use an organic mulch, like pine needles or chopped bark.
The winter landscape will be more interesting if you leave spent Russian sage plants alone in the fall. However, excessive trimming encourages new growth, which increases the plant’s susceptibility to winter harm. If you don’t like how the Russian sage is growing unpruned, tidy up the plants with a light pruning, but wait until spring to cut the Russian sage to the ground.
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.
How can Russian sage be controlled?
What may my Russian sage plant be used for? It appeals to me, and I appreciate that it blooms throughout summer. It generates a lot of sprouts and expands out of control, which is what I don’t enjoy. Is there a way to manage these sprouts without destroying the plant as a whole?
Answer:
The Russian sage plant has lovely blossoms that, as you mentioned, have the bad tendency to spread quickly. You can try a number of methods to control its uncontrollable growth.
Herbicides for contact are one alternative. These herbicides exclusively harm the specific area of the plant to which they are sprayed. They will not destroy other areas of the plant like translocated (systemic) herbicides do since they cannot migrate through the plant. Apply this to the undesirable sprouts. These sprouts will reappear below the herbicide’s active level, though.
Reducing the water they receive is another factor to take into account. When properly irrigated, Russian sage plants will grow huge. The plant won’t get as big if the irrigation is restricted, but it will still produce blossoms. Fertilizer will promote growth, particularly nitrogen fertilizer. Decrease the amount of nitrogen fertilizer you give the plant. Choose a fertilizer with a high phosphorus content that contains little to no nitrogen because phosphorus is more crucial for flowering (read the label for this information). What you require should be available from superphosphate and colloidal phosphate. In our calcareous soils, bonemeal is not an excellent source of phosphate.
Russian sage can be controlled from spreading by planting it in an area where it can expand and form a substantial cluster. The Russian sage can also be restrained by being surrounded by plants that are fiercely competitive. In Uzbekistan, I observed Russian sage flourishing in its natural environment. The grasses encircling them in competition with the Russian sage plants prevented the Russian sage from growing rapidly, which is why the plants weren’t big and sprawling. Around my Russian sage in my yard, I’ve put Mexican hat and chocolate flower plants. For nutrients and water, these plants compete with Russian sage. They successfully slow the growth of the Russian sage in this way. These aggressive plants are simpler to manage because they don’t have rhizomes, which are underground runners. When the competitors spread too far, they might need to be cut back. Additionally, the seedlings of the rival plants must be taken out. It may take up a lot of room to grow Russian sage alongside other competitive plants, but it looks nice and the other plants help to control each plant’s size.
