Once established, Russian sage is a low-maintenance herbaceous, woody perennial or subshrub that is simple to maintain. The enticing tubular flowers are a favorite of hummingbirds, bees, and butterflies and bloom for an incredibly long time. This mint cousin, which is native to central Asia, has silvery-green leaves that release a strong aroma when crushed.
Russian sage is hardy in USDA zones 4 through 9, but in colder areas, it will benefit from winter protection. While some types can be larger, most only grow to be 2-3 feet tall and wide. Russian sage is appropriate for water-conscious landscapes because of its high heat and drought tolerance. This adaptable perennial plant can be used as a filler in a mixed border, as hedging, in mass plantings throughout the landscape, or in containers.
Russian sage is it intrusive?
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.
Does Russian sage develop quickly?
Either early spring or late fall are suitable times to plant Russian sage. To encourage proper drainage and guarantee a successful overwinter, choose a sunny location for your plants with soil that is on the grittier side (sandier loam).
Light: Russian sage should be grown in full sunlight. The plant will flop over and get leggier in partial sunlight.
Russian sage is a great choice for rocky, less fertile, poorer soils. It thrives in alkaline environments (pH > 7) but is intolerant to soggy, acidic soils.
Russian sage should be planted 24 inches apart to allow for the ultimate spread of the plant.
Slow-growing and unable to spread, Russian sage develops a woody stem structure at the base of the plant. It can produce offsets (‘mini’ plants with incomplete root systems’) at the base once it reaches maturity.
Russian sage should be planted in the early spring or early fall to give its roots time to grow over the off-season.
Can Russian sage be controlled in size?
Russian sage can be planted with a few tips that will aid in the plant’s establishment in your garden.
Place your planting first. For the Russian sage to flourish, full sun is necessary. Plants tend to flop open as stems stretch for sunlight when given a little shade. A stretch along a driveway or an area with high sun that gets as hot as the area between a sidewalk and a street are good choices. Russian sage enjoys heat and sunlight.
When planting Russian sage, keep in mind that this lovely plant dislikes two things: high humidity, and soil that remains wet all year. Select a planting location with alkaline, dry soil or ordinary, well-drained soil. Both soil types are compatible with Russian sage. Plants often become slack and floppy in overly fertile soil. Insert hoop stakes or support stems with stakes and string in this situation.
Plants mature at a height of 3 to 5 feet and a spread of 2 to 4 feet. Russian sage grows in clumps, so provide the plants some room to expand by placing them about three feet apart or three feet away from other plants in the garden.
At your preferred plant store, keep an eye out for containers of Russian sage. Russian sage can be planted any time between early spring and six weeks before the first frost, but late spring is the best time. The earth is now warm, and plants should begin to grow swiftly. If you decide to plant Russian sage later in the summer, make sure to water the soil frequently as the young plants grow.
There are numerous types of Russian sage for sale. The straight species can reach heights of 3 to 5 feet and widths of 2 to 4 feet. Russian sage known as “Little Spire” is a scaled-down kind that grows only 18 to 24 inches tall and wide. Russian sage known as “Blue Spire” has stems that may grow up to three feet tall and wide and is known to grow more uprightly than other varieties.
In the correct circumstances, Russian sage can self-sow and can also spread via rhizomes. Gardeners claim that this perennial bloom can occasionally be invasive. The National Invasive Species database does not, however, report or list it as such. Keep an eye out for spreading stems in the garden. As you find them, pull and cut them.
How much space between Russian sages is ideal?
- The upright variant “Blue Spire” has leaves that are deeply lobed. It stands three feet tall. Larger panicles bear the rich purple blooms.
- German Ernst Pagels’ introduction, “Filigran,” is used. In comparison to the species, this variety’s foliage is finer and more intricate, giving the plant an almost lacy appearance. On upright, 2-3 foot spikes, the vivid blue flowers bloom throughout the summer.
- ‘Little Spire’ is a more compact kind that only reaches a height of 2 feet.
- Because of its stiff stems, “Longin” has a more formal, upright growth habit.
Russian sage should be planted with a plant spacing of around 18 inches in full sun and well-drained soil. Container-grown plants should be put at the same depth as when they were in the pot in the early spring, but they can also be planted outside in the summer up until one month before a harsh death frost. Small plants could take longer to take root. To build a broad, deep root system throughout the first growth season, water frequently. Once established, plants can withstand drought quite well.
Once established, Russian sage is simple to grow and virtually free of disease and insect issues. The plants have a propensity to floppiness, particularly when young. You can stake Russian sage or place it next to other plants that will sustain it. They can also be simply let go for a more casual appearance.
The plant may tolerate wet winters with proper drainage and aeration. When the soil is excessively wet, plants will rot. To prevent the plants from becoming woody, leave the old stems on throughout the winter and trim them to approximately a foot in the spring (which can result in a reduction in foliage and flower quality). Before springtime new growth starts, fertilize. Propagation
From seeds, Russian sage can be grown. At any time of the year, plant seeds by simply covering them with soil. Typically, germination takes 1-4 months at an ideal temperature of 60–65 °F. A 10- to 6-week initial cold treatment at 35° to 44° F may promote germination and result in a more compact plant. When the seedlings are big enough to handle, transplant them, being careful not to injure the roots. Before putting the seedlings in the garden, harden them off, ideally in the late spring.
Taking 3–4 inch long softwood cuttings in the summer is the most effective way to increase named cultivars. Although sluggish, division-based reproduction is conceivable. University of Wisconsin’s Susan Mahr
Do mosquitoes stay away if you use Russian sage?
WMBF-CONWAY, SC – Don’t use too much bug spray if you’re having a party on the patio over Memorial Day weekend.
Many of the plants that might deter mosquitoes are currently highly popular at Conway’s Plants Direct Nursery.
The nursery’s proprietor, Randy Gaskins, recommended ten plants to keep mosquitoes at bay.
Initially, wax myrtle. When the leaves are brushed together, the plant emits a faintly fragrant smell.
Because it’s a native, Gaskins added, it’s very affordable to use as mosquito control in the area. The plant thrives in pots and can be used as a hedge in the front or back yards.
Rosemary, second. This plant is well recognized for giving any dish made at home taste, but it can also keep insects away.
It’s a terrific container plant, so Gaskins advised using pots of it around your patio where guests would be congregating for a party.
Bee Balm comes next. Bees might be drawn to it, but not mosquitoes. The plant has several distinct hues and a lovely, fragrant blossom. Gaskins claimed that it also functions as a repellant.
Society Another repellant is garlic. It smells like garlic, as the name would imply, and deters insects as a result.
Although Lemon Verbena and Russian Sage are both used in cooking, mosquitoes are deterred by their different aromas.
Lavender is likewise well-liked, particularly inside, but according to Gaskins, it also acts as a repellant.
According to Gaskins, the Dusty Miller plant has attractive foliage color that aids in mosquito repulsion.
The most well-known and productive plant, according to Gaskins, is citronella. Rub the leaves together, and the fragrance is exactly like a citronella candle.
According to Gaskins, the better it dissipates the stench the more you rub it and someone brushes against it. “The plant looks excellent in a pot outside or planted by a deck, patio, or backyard.
Gaskins advised people to get rid of pots, buckets, and anything else holding standing water to prevent mosquitoes. He continued, “It negates the purpose of having plants that repel mosquitoes.”
Russian sage is it messy?
Avoid making the same error as me and planting Russian Sage close to the pool where it can hang over the water because it too has a tendency to “drop” its tiny blooms in an untidy manner. USDA hardiness zones 5 through 9 support growth.
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.
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.
How do you prevent the spread of Russian sage?
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.
