Russian sage (Perovskia atriplicifolia) is a popular perennial plant known for its aromatic foliage and beautiful purple flowers. However, if you notice that your Russian sage plant is growing sideways instead of upright, there are a few possible reasons for this issue. In this article, we will explore these reasons and provide some tips on how to encourage your Russian sage plant to grow upright.

Insufficient Sunlight

One of the main reasons why your Russian sage plant may be growing sideways is due to insufficient sunlight. Russian sage is a sun-loving plant that requires at least six to eight hours of direct sunlight daily to thrive. If your plant is not receiving enough sunlight, it will start to lean towards the direction where it can get more light.

To rectify this issue, consider relocating your Russian sage plant to a sunnier spot in your garden. Choose a location that receives full sun throughout the day. If you have limited sunny areas in your garden, consider pruning nearby trees or shrubs that may be casting shade on your Russian sage plant.

Improper Soil Conditions

Another factor that may contribute to the sideways growth of your Russian sage plant is improper soil conditions. Russian sage prefers well-draining soil with a pH level between 6.5 and 7.5. If the soil in which your plant is growing is heavy and retains too much moisture, it can lead to weak root development and ultimately cause the plant to lean or grow sideways.

To ensure proper soil conditions for your Russian sage, amend the soil with organic matter such as compost or well-rotted manure to improve drainage. Additionally, avoid overwatering your plant as excessive moisture can be detrimental to its growth. Water your Russian sage deeply but infrequently, allowing the soil to dry out between waterings.

Lack of Support

Like many tall perennials, Russian sage can benefit from some form of support to help it grow upright. Without proper support, the weight of the foliage and flowers can cause the plant to bend or lean sideways. This is especially common in windy areas where the plant may be more prone to bending.

To provide support for your Russian sage, consider using stakes or a trellis. Place the stakes around the plant, ensuring they are firmly inserted into the ground. Gently tie the stems of the plant to the stakes using soft garden twine or plant ties. This will help keep the plant upright and prevent it from growing sideways.

Overcrowding

Overcrowding can also contribute to the sideways growth of your Russian sage plant. When plants are too close together, they tend to compete for resources such as sunlight and nutrients, resulting in weak and spindly growth. If your Russian sage is growing sideways due to overcrowding, it is important to give it more space to grow.

To address this issue, consider thinning out nearby plants or transplanting your Russian sage to a location where it has more room to spread out. Giving your Russian sage enough space will allow it to grow properly and prevent its tendency to lean or grow sideways.

Pruning Techniques

Lastly, improper pruning techniques can also cause your Russian sage plant to grow sideways. Russian sage should be pruned in early spring before new growth emerges. If you prune your plant too late in the season or cut it back too severely, it can lead to weak and floppy growth.

When pruning your Russian sage, make sure to remove only about one-third of the plant’s overall height. Focus on removing dead or damaged wood and cutting back any overly long or leggy stems. By following proper pruning techniques, you can promote a more compact and upright growth habit in your Russian sage.

In conclusion, if your Russian sage plant is growing sideways instead of upright, there are several possible reasons for this issue. Insufficient sunlight, improper soil conditions, lack of support, overcrowding, and improper pruning techniques can all contribute to the sideways growth of your plant. By addressing these factors and providing the necessary care, you can encourage your Russian sage to grow upright and enjoy its beautiful flowers in all their glory.
