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.
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.

How can you prevent sage from growing?
Our landscaper installed several Russian sage plants around five years ago, and they are a nuisance. There are three of them, all healthy and lovely, however they produce a lot of suckers and are challenging to remove.
I used to trim the originals back in the fall, but I stopped because I felt maybe I was encouraging them to spread. Last winter, I let them look scraggly, only to discover that they were still growing.
Russian sage appears to be a plant that can be described as both Jekyll and Hyde. Many of you “fortunate” people have plants that are too aggressive for their own good, but a few people I’ve spoken to don’t appear to have issues with the suckering.
It makes no difference whether you cut them back or not whether they succumb. I can’t give you a simple response. Planting Russian sage with a drip emitter or two close by in a dry, xeric environment seems to be one way to prevent the issue from happening. As a result, the plant usually stays in the irrigated area.
Although it doesn’t always succeed, most plants appear to conduct themselves better in these kinds of circumstances.
Planting a Russian sage inside of a “sleeve” that inhibits the plant’s subterranean runners, or rhizomes, from spreading out is another technique to keep it contained.
Use a plastic nursery pot that has had the bottom taken out. I would use one that was rather huge, maybe 1420 inches in diameter. Put the Russian sage in the center and bury it completely.
The plant won’t grow as large or vigorously as a result of this slight root restriction, but those rhizomes will still be present.
You should avoid beginning to apply herbicides. The ones that work have systemic effects and end up harming or destroying the mother plant.
There isn’t much of an alternative to using contact-type weed killers. These herbicides won’t harm the mother plant, but you must keep spraying for as long as you have the plant, and Russian sage is a semi-woody plant, so they don’t actually work that well on it.
Sucker Punch is a substance that slows the suckering of problematic plants like these. After removing the suckers, you spray the solution on the ends that you just cut. It prevents the plant in that location from sucking.
Even though you’ll have to do it every year, at least you’ll be free of those bothersome suckers!
The only other choice is to keep excavating the suckers like you’ve been doing it all along.
Since it is difficult and messy job, as you indicated, many people eventually just dig the plant up and get rid of it completely.
A Russian sage: how can you get rid of him?
Instead of eliminating the Russian sage by hand, use a systematic herbicide. Russian sage can be killed by the herbicide prodiamine, which has the active component, according to Ohio State University. On a quiet day, apply directly to the leaves. Read the herbicide’s label for proper application instructions.
Do you cut the Russian sage back?
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 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.

- Russian sage that has become overgrown can start to look straggly, but the plants can be revitalized with appropriate trimming and division.
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.
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.
Russian sage has runners, right?
Care for Russian Sage Being a member of the mint family, Russian sage spreads by runners and must be controlled to prevent it from spreading in undesirable areas. In the early spring, pull up suckers. Every four to six years, divide the plants to keep them fresh.
How can invasive herbs be managed?
There are two ways to grow invasive herbs in containers. Individual containers can be filled with herbs and left above ground, or you can bury the containers in the ground.
It’s recommended to utilize plain, plastic containers made of plastic when you opt to recess your containers, such the ones you buy plants and seedlings in. However, avoid planting the invasive herbs in the same container that you bought them in. To give your plants room to develop and flourish, use a container that is one or two sizes larger.
Dig a hole big enough for the entire pot of invasive herbs to fit into, leaving the lip (top portion) of the pot jutting out about one or two inches (2.5-5 cm.). Make sure the container you use has drainage holes. To ensure appropriate drainage of the pot, fill the bottom of the container with gravel or Styrofoam pellets. Plant the herb into the buried container, then add some potting soil.
To prevent them from becoming root-bound, your container-grown herbs will need to be dug out and divided once every two to three years.
By erecting borders around invasive herbs that are sown straight into the garden, you can practice compartment gardening.
Use metal or plastic edging to surround your invasive herbs to create distinct divisions. To prevent your herbs from spreading, the edging needs to be buried pretty deeply.
Some herbs spread swiftly and easily, which causes them to become invasive. These herbs include lemon balm and comfrey. Check the area around these plants frequently to see if any unwelcome baby seedlings are sprouting above or below them.
Some herbs spread through rhizomes, which causes them to become invasive. A horizontal plant stem known as a rhizome has roots that extend below ground and shoots that emerge above it. These are also known as creeping rootstalks or rootstocks. The plant reproduces by sending out runners. Bee balm and all members of the mint family reproduce in this manner. Always scan the area around these plants for runners, which must be eliminated right away before they take root.
Invasive herbs can be a welcome addition to your herb garden if you take a little additional care.
Should the sage be trimmed back?
Sage should be pruned in the early spring. The plant can struggle to survive the winter if the leaves are clipped before then. The shoots can now be pruned back to around 5 cm in February. When the weather improves after pruning, the sage will sprout new leaves and become bushier.
