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 much of my Russian sage should I cut back?
Cut back Russian sage, butterfly bush, and pest-free perennials in the late winter or early spring. These plants become more hardy when allowed to stand during the winter, according to research. Additionally, the winter environment is made more interesting by the form, texture, motion, and bird-attracting elements. Trim the Russian sage to a height of 4 inches or less. You can give your plants another clip if they have a tendency to flounder in the heat. Once the plants are 12 inches tall, cut them back halfway. Little Spires is a shorter (four foot tall) cultivar of Russian sage that is less prone to flopping, so those thinking about include it in their gardens might want to give it a try.
When do you trim back Russian sage for the year?
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 should a Russian sage patch be handled?
Although it grows with a slightly woody, shrub-like form like to garden sage and is a robust, drought-resistant member of the mint family, Russian sage (Perovskia atriplicifolia) (Salvia officinalis). Russian sage plants have an open, airy habit, gray-green foliage, and modest blue-purple flower spikes that resemble a multicolored mist. They can grow up to three feet tall and just as broad. Due of the plant’s strong perfume, deer and rabbits avoid eating it. Russian sage that has become overgrown can start to look straggly, but the plants can be revitalized with appropriate trimming and division.
To stop outer stems from roots, remove them in late summer or early autumn after they have fallen flat to the ground.
In the late fall, trim away any dead leaves from the area surrounding the plant’s base. Keep stems that are upright throughout the winter.

Early in the spring, use anvil pruners to trim the stems from the previous year to a height of 6 to 8 inches from the ground. Examine the thicker, woodier stems at the base and cut off any that appear rotten or don’t appear to be budding.
If after pruning, the plant base is still too big for the area, divide it. At the appropriate division point, use a flat-bladed shovel to quickly dig down into the plant and root stock.
Take the extra plant material out. Sand and compost should be combined, then used to fill the hole created by removing the divide. You can either replant the removed section or throw it in your compost bin.

Replace your Russian Sage with newly propagated new specimens to revitalize it. Several stems that have flattened to the ground in the late summer should be covered with a shovel’s worth of dirt to help them take root. Replace the old plant with the newly rooted plants after digging it up.
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.
