Also known as a form of pruning, deadheading is an important action that can ultimately help to remove aging flowers on your Liatris spicata. In this guide, we’re going to thoroughly cover the concept of deadheading and why it is important to consider when maintaining your Liatris. 

How To Deadhead Liatris

Once a Liatris nears the end of its blooming cycle, it might be time to consider deadheading the flowers. Simply cut the stem below the flower and ensure that the new healthy leaves that are emerging are not harmed during this process. All of the dying flowers on your Liatris should be cut and pruned, if possible. 

Deadheading your Liatris plants can help boost your plant’s growth in the future and may even provide an important boost to your plant’s flowering in the next cycle of growth. Since Liatris varieties are perennial plants, this cycle is important to monitor and deadheading or pruning will surely be beneficial in the long run when done properly.

The process of deadheading should begin as soon as your flowers begin to fade out of their blooming season. The weeks immediately after their blooming season ends is usually a good time to consider starting the deadheading process for your Liatris plants.

Why is ‘Deadheading’ Important for Liatris?

While it may not be absolutely required for your Liatris to grow properly, it’s generally a pretty good idea to consider deadheading your Liatris after the blooming season comes to an end.

The reason that it is important to prune and cut dying flowers off of your plant is that it can help with re-flowering in the next cycle of growth. Many people believe that a routine that includes deadheading for Liatris plants will ultimately end up with higher-quality growth in your Liatris and healthier plants overall.

Perennial plants, like Liatris, will go through phases every single year. After blooming, they will start to deteriorate in visual appearance. This is generally a signal to you that it’s almost time to deadhead your plants by cutting off the dying flowers. If you choose to deadhead your plants and remove the expired flowers from your Liatris, you’re basically giving your plants an energy boost that will help them reflower in their annual cycle. 

While it’s not a mandatory step of maintenance, it is definitely recommended and should be strongly considered if you are trying to maintain your Liatris plants within your garden.

How Should You ‘Deadhead’ Liatris?

Now that you understand why it’s important to consider deadheading your dying Liatris flowers, let’s talk about how you should go about it. The truth is that it sounds a lot harder than it actually is. While you still may be stressed out about it if you have never done it before, consider this simple guide to help you. 

Before you begin, you need to know when it is appropriate to deadhead Liatris. Understanding the timing of this process is almost more challenging than actually doing it.  As previously mentioned, a clear signal will be sent to you from the plant when the blooming season ends and its appearance starts to degrade in the following weeks. 

Once the visual appearance of your Liatris starts to deteriorate, it’s going to most likely be a great time to start the deadheading process. Approach your Liatris plant and make a simple cut of the dying flowers by removing the stem just below the expired flower. Make sure not to cut any of the new healthy growths below it, or you might accidentally harm your plant’s growth in the future.
