How do you prune salvias?

Answered by Randy McIntyre

Pruning salvias is a relatively easy task that can help promote healthier growth and encourage more blooms. Here is a step-by-step guide on how to prune salvias effectively:

1. Timing: The best time to prune salvias is after the flower spikes have faded, which generally occurs in early summer. By waiting until this point, you allow the plant to fully utilize its energy for blooming before trimming it back.

2. Cutting back the stems: Once the flower spikes have faded, it’s time to cut the stems right back down to the base. This means trimming the stems all the way to the point where they emerge from the main plant. Use clean and sharp pruning shears to make clean cuts, as this minimizes damage to the plant and reduces the risk of disease.

3. Encouraging a second flush of blooms: Pruning salvias in this manner actually encourages a second flush of blooms. By cutting the stems down, you stimulate new growth from the base of the plant, resulting in additional flower spikes later in the season. This can prolong the blooming period and enhance the overall appearance of the plant.

4. Winter protection: After you have pruned the salvias, leave the second lot of stems over winter. These remaining stems can provide protection for the new growth that will emerge in the following spring. They act as a natural barrier against frost, shielding the base of the plant and helping it survive the colder months.

5. Maintenance pruning: In addition to the initial pruning after flowering, you may need to perform maintenance pruning throughout the growing season. This involves removing any dead or diseased stems, as well as cutting back any excessive growth that may occur. Regular maintenance pruning helps keep the plant healthy and aesthetically pleasing.

Personal experience: I have been pruning salvias in my garden for several years now, and I have found this method to be highly effective. By cutting the stems back to the base after the first round of flowering, I have consistently witnessed a second flush of beautiful blooms later in the season. It not only extends the blooming period but also adds vibrancy to my garden during the summer months.

Pruning salvias is a simple task that involves cutting back the stems after the flower spikes have faded. This promotes a second round of blooms and protects new growth from winter frosts. By following these steps, you can ensure healthier and more abundant growth in your salvias.
