Yes, cuttings can be rooted in water to spread Russian sage.
The new plant can then be planted in the ground after developing roots at the stem’s nodes.
Russian sage’s lovely purple blossoms are a wonderful addition to the garden.
Additionally, it can withstand drought and is resistant to deer, making it the ideal choice for individuals who have difficult gardening.
Can cuttings of Russian sage be rooted?
Russian sage has been a mainstay in perennial programs and landscapes across the nation ever since the Perennial Plant Association named Perovskia atriplicifolia as the 1995 Perennial Plant of the Year. This sturdy perennial has grayish foliage and silver stems, and in the middle of the summer, it bears tiny light blue to lavender flowers. Perovskia is a dependable and highly prized perennial for the landscape because of these landscape characteristics.
Commercial growers have historically introduced and grown relatively few named cultivars; in fact, the straight species P. atriplicifolia has received more cultivation to yet than any named cultivar. However, new cultivars are being found as a result of plant selection efforts. Peter Catt from the United Kingdom’s Liss Forest Nurseries Ltd. recently made the discovery of “Lacey Blue.” This cultivar has many desired qualities that professional growers and landscapers are looking for, and it is certain to provide new excitement to a genus that is already well-liked and dependable.
With fragrant grey-green foliage, “Lacey Blue” grows into compact, bushy mounds that are 18 to 20 inches tall. It blooms profusely, producing masses of blue-purple flowers from the middle of summer to the end of the season. The quality of the plant in bloom is not compromised by its small stature; in fact, “Lacey Blue” boasts the largest blossoms of any Russian sage now being produced.
Perovskia ‘Lacey Blue’ performs admirably in gardens and thrives in sunny settings in USDA Hardiness Zones 4 to 9. Russian sage is frequently used as cut or dried flowers, as border and mass plantings, and in containers. Perovskia also resist deer grazing, are drought tolerant, and draw hummingbirds to the garden. With these qualities, applications, and simplicity of creation, “Lacey Blue” will be a great addition to most enduring projects.
Propagation
Tip cuttings are used for vegetative propagation of Perovskia ‘Lacey Blue’. Unlicensed propagation of this cultivar is forbidden as a plant patent application (PPAF-Plant Patent Applied For) is being made.
By placing cuttings straight into liner trays with a pre-moistened, well-drained growth medium, cuttings can be effectively rooted. Perovskia may root well without the aid of rooting agents. High humidity works better for Russian sage propagation than misting. For the first week or so of cutting propagation, spray the cuttings lightly, then progressively reduce it as time goes on. As the cuttings start to form roots, start giving them complete water-soluble fertilizer at 150 ppm nitrogen once a week (usually between 10 and 14 days). With soil temperatures ranging from 68 to 74 F, the typical rooting period lasts four to five weeks.
Production
For 1-quart to 1-gallon containers, use Perovskia “Lacey Blue.” When planting large containers in the spring, such as 1-gallon pots, I advise planting at least two liners per container (depending on the size of the pot) to properly fill out the pot for same-year sales; when planting in the late summer of the year before the containers are to be sold, fewer liners per pot are frequently sufficient.
Russian sage thrives best when it is grown in a moist, well-drained medium with a pH range of 5.8–6.5, which is slightly acidic. If there is sufficient drainage, the majority of peat- or bark-based growth mixtures are effective. The liners should be inserted into the new container such that the original soil line of the plug is level with the top of the growing medium. The finest quality is obtained when plants are cultivated in greenhouses with high light intensities or in the full sun (greater than 4,000 foot-candles).
Although it is rarely necessary, pinching can occasionally be beneficial to enhance lateral branching, plant fullness, and the overall amount of blooms produced on each plant. Typically, a mild pinch is used, leaving at least four to six leaves (nodes) on each stem while just removing the plant’s growth point.
Irrigation needs for Perovskia are ordinary to slightly below average. Avoid excessively damp growing conditions because they may cause stunted growth, root rots, and plant death. When irrigation is required, make sure to water them well and let the soil gradually dry in between.
Moderate plant nutrition requirements apply to Russian sage. When necessary, growers frequently use 150 to 200 ppm of nitrogen in water-soluble fertilizers, or they continuously administer 75 to 100 ppm of nitrogen in liquid fertilizer with each irrigation. Prior to potting, 0.9 to 1.2 pounds of elemental nitrogen per cubic yard of growing mix are often added as controlled-release fertilizers.
‘Lacey Blue’s’ compact growth habit means that height management is typically not necessary. Water management, avoiding high fertilizer levels, and ensuring appropriate space between the plants can all be used to efficiently control plant height. If required, the plants can be toned using tank mixtures of 2,000 ppm daminozide and 3 ppm uniconazole or spray applications of 2,500 ppm daminozide (B-Nine, Dazide) (Concise, Sumagic).
Insects and Diseases
When cultivating perovskia, growers are unlikely to encounter many issues with insects or diseases. Russian sage is occasionally seen being consumed by aphids, leafhoppers, spider mites, and whiteflies, but these pests rarely cause serious crop harm.
Growers may occasionally notice the following plant pathogens: Cylindrosporium leaf spot, Phoma-caused stem canker, root rots, and Sclerotinia stem blight. Regular scouting is helpful and advised to identify insect pests and plant diseases early, allowing the implementation of the proper control techniques prior to substantial crop damage or mortality.
Forcing
I advise farmers to transplant “Lacey Blue” during the late summer of the year before the plants are to be marketed if they are producing 1-gallon or larger-sized containers; this will afford enough time for bulking and will result in fuller, higher-quality plants.
Perovskia are cold-tolerant plants that bloom whether or not the soil has been vernalized. Compared to plants that haven’t gotten a cold treatment, vernalized plants typically have more blooms and greater branching. Plants that have grown larger before a cold period arrive will benefit from vernalization the most (six to nine weeks at 35 to 44 F). Unless they have been vernalized, Russian sage typically needs long day lengths to flower; however, after receiving a cold treatment, they will bloom under any day length. When cultivated at 65 to 68 F after vernalization, perovskia can be coaxed into bloom in 10 or 12 weeks.
Get a hold of some sage
If you are cultivating your own sage, all you need to do is snip off a few healthy, non-flowering sprigs. There is no need to remove entire branches; sprigs that are 4-6 long will do just fine.
Although you can take cuttings at any point during the growth season, the ideal time is as the weather turns chilly and the stems start to get a little woody at the end.
Most grocery stores and farmers’ markets sell packs or bunches of fresh sage if you aren’t already growing it and don’t know of anyone who is willing to share theirs. While cutting sprigs directly from the plant is undoubtedly preferred, very fresh sprigs that are purchased can also be used.
While perennials like sage can be planted in the spring or the fall, annuals should be planted in the spring. Since a sage bush’s stems become more woody at their base in the fall, that season is preferred. Your cutting is strengthened for propagation as a result.
Strip leaves off the bottom 2 of the sage sprig
Once you have a sage sprig, remove the lowest leaves—you want around 2 inches of bare stem—as this will be the starting point for the sprig’s roots in the future.
Cut the sprig’s tip at a 45-degree angle if you want to propagate it immediately soon. This will guarantee that the sage sprig’s center receives some recent exposure.
The sprigs can be kept in your refrigerator, wrapped in a plastic bag, if you aren’t ready to propagate them just yet.
[Optional] Dip the stem into a growth hormone
You now have the option of immersing the naked stem of the sprig into a rooting hormone.
In particular, when it comes to a plant that can be eaten, like sage, the use of a growth hormone is entirely optional. Although it could be required for stronger roots, you can usually get away without it.
You may get growth hormones from your neighborhood garden center in either the powder or gel form if you decide to use them for a quicker and healthier root system. Simply dunk your stem in water first, followed by growth hormone.
Please be aware that most hormones (whether in powder or gel form) will require you to wait a full year before consuming any parts of the plant while cultivating sage. For more specific instructions, make sure to read the growth hormone label before buying.
Start the root structure
If you decided to use a growth hormone to start the plant, you can plant the stem in potting soil to make sure it has sufficient drainage.
Your cuttings should be planted in a small pack or pot since they are currently only little sprigs. This will enable you to relocate the plant if necessary.
Before planting in soil, you need build a root structure if you aren’t using a growth hormone. To do this, submerge the two bare stems of your sage plant completely in a glass of water. You should begin to notice roots emerging from the stem after 3 to 4 weeks.
The cutting is ready to be planted in potting soil once it has developed a few roots. Make sure the sprig’s stem has good soil contact so that the root system may develop right away.
Remember that at this point, your cutting will be very delicate. A cutting will be more affected by soil conditions than an established plant would be by wet, dry, cold, heat, etc.
Wait 6-8 weeks for maturing plant
The length of time it takes to root up and flourish will vary depending on what season you are propagating in. Usually, you’ll start to notice some signs of growth around 6–8 weeks.
Your sage plant will thrive in a warm, damp environment. This weather is ideal if you have a greenhouse. If not, covering the plant and container with a plastic bag will have the same effect. Keeping the plant outside may be sufficient, depending on the environment you are growing in.
After a few weeks, if you find that the leaves are beginning to turn yellow, this could be the result of transplant shock (much like people, plants don’t enjoy fast change). Simply cut off the yellow leaves in this instance to make room for new development.
Care for your new sage plant!
Now that your plant has sprouted, it’s time to start caring for it like any other young plant you might buy from a nursery or growing facility.
Make sure the sage plant receives enough light. Sage plants typically require at least a half-worth day’s of direct sunlight.
Keep after watering your new sage plant, please. Sage plants, like the majority of other herbs, require a modest amount of water to truly flourish. Check the top half of the soil for moisture to determine whether your sage plant needs to be watered. It has to be watered if it’s dry.
The sage plant will eventually overflow its initial container. In this situation, the plant can either be put in the ground or moved into a bigger pot.
How can Russian sage be re-rooted?
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 long does it take for cuttings to root in water?
Cuttings can be grouped together in a single container. Before the cuttings are completely rooted, make sure to add new water as necessary. Most plants will begin to root in 3–4 weeks, but others can take longer. The cutting is prepared for potting when the roots are at least 1-2 inches long.
When may I take Russian sage cuttings?
Since most plain garden soil already contains more nutrients than the sage is typically used to, applying chemical fertilizers is neither necessary nor even desirable for Russian sage because it is well acclimated to barren soils.
When selecting a location to cultivate Russian sage, you might want to keep in mind that it draws bees.
Perovskia atriplicifolia, sometimes known as Russian sage, is a perennial sub-shrub that blooms in the summer and fall with spires of blue and lavender flowers. Russian sage is hardy in USDA zones 5 through 9 and requires just light watering and sporadic pruning for shape and size to perform well despite less-than-ideal soil and temperature conditions. Russian sage is a woody perennial with flowers that can be spread both by seed and by cuttings.
At the conclusion of the bloom cycle, gather the seeds of Russian sage from the drying seed heads. Pluck or chop off the seed heads while holding them over some paper or another flexible surface. Then, funnel the seed heads into a small airtight container or resealable plastic bag until planting. Seeds should be buried one inch deep in nursery pots or trays of fresh potting soil before being thoroughly watered.
Use a clean garden knife or secateurs to cut soft wood cuttings off your Russian sage in the late spring or early summer. To ensure that the cutting is not harmed by removing the leaves, make cuttings that are at least 5 inches long and leave any foliage in tact. Make a fresh cut on the woody cutting’s bottom end, then quickly dip it in water and rooting hormone powder to coat the bottom inch or so. Put the cutting’s bottom end quickly and gently into some loose potting soil. To support the cutting, lightly compact the earth around it, and then thoroughly water it.

Put your seed pots and cuttings in a well-lit, moist area that is shielded from the wind and from temperatures that are below 55 or 60 degrees. To assist germination, keep the soil consistently moist. Check on it every day as letting the soil become too dry, especially for cutting, might result in a high failure rate. Within a few weeks, pale whitish shoots should start to appear as an indication of successful germination.
When the seedlings are at least a foot tall, plant them outside in the garden. Before winter, seeds sown in the spring and cuttings prepared in the summer should have enough time to establish and harden off. In order to prevent the sensitive young plants from being destroyed by winter temperatures, the indoor housing period may need to be extended if they are propagated later in the season.
