Propagation Techniques
Russian sage can be propagated through several techniques. Dividing the plant is one of the easiest ways to propagate Russian sage. It is best to divide the plant in early spring before new growth appears. Carefully dig up the plant and separate the clumps into smaller sections, making sure that each section has a healthy root system. Replant the sections in well-draining soil and water thoroughly.
Another way to propagate Russian sage is through basal cuttings. Basal cuttings are taken from the base of the plant in early spring before new growth appears. Cut a 3-4 inch stem from the base of the plant and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a pot with well-draining soil. Keep the soil moist and place the pot in a warm, bright location. In a few weeks, the cutting should develop roots and can be transplanted into the garden.
Russian sage can also be propagated from seeds. Collect the seeds from the plant in the fall and store them in a cool, dry place until spring. In early spring, sow the seeds in a pot with well-draining soil. Keep the soil moist and place the pot in a warm, bright location. In a few weeks, the seeds should germinate and can be transplanted into the garden.
Finally, Russian sage is a subshrub, which means that it can be propagated through layering. Layering is a technique where a stem is bent down and buried in the soil, allowing it to develop roots. To propagate Russian sage through layering, select a healthy stem and bend it down to the ground. Make a small cut on the stem where it touches the ground and bury it in the soil. Keep the soil moist and in a few weeks, the stem should develop roots. Cut the stem from the parent plant and transplant it into the garden.
Companion Planting
Russian sage is a great addition to any garden, and it can be even better when planted alongside certain other plants. Companion planting can help to create a beautiful and harmonious garden, and it can also help to improve the health of your plants. Here are some plants that can be great companions for Russian sage:

Common Pruning Mistakes and Solutions
Improper pruning can lead to a number of problems with Russian Sage, including reduced flowering, weak growth, and a lack of overall vigor. Here are some common mistakes to avoid when pruning and solutions to help you achieve optimal results.
1. Pruning at the wrong time
Russian Sage should be pruned in the early spring, just as new growth begins to emerge. Pruning at any other time can result in reduced flowering and weakened growth. If you accidentally prune your Russian Sage at the wrong time, don’t worry – it will likely recover, but it may take a season or two to do so.
2. Over-pruning
Over-pruning can be just as harmful as under-pruning. Removing too much of the plant can lead to a lack of vigor and reduced flowering. When pruning, it’s important to never remove more than one-third of the plant at a time. If you need to remove more than that, do it over the course of several seasons.
3. Using dull or dirty pruning tools
Using dull or dirty pruning tools can damage the plant and make it more susceptible to disease. Make sure to use sharp, clean pruning shears or loppers when pruning. If your tools are dull, have them sharpened before you begin.
4. Failing to encourage new growth
Pruning is an important part of encouraging new growth in Russian Sage. When pruning, make sure to cut back to a healthy bud or branch. This will encourage new growth and help to keep the plant looking full and healthy.
5. Ignoring texture
Russian Sage is prized for its airy, wispy texture. When pruning, make sure to preserve this texture by only removing dead or damaged branches. Avoid pruning too heavily, as this can result in a dense, bushy appearance that detracts from the plant’s natural beauty.
By avoiding these common pruning mistakes and following the solutions provided, you can ensure that your Russian Sage stays healthy, vibrant, and full of fresh flushes of flowers year after year.
