Removing Siberian Iris Flowers – Does Siberian Iris Need Deadheading?

Siberian irises are beautiful flowers with long stems and white petals. They have a very unique appearance, which makes them look so appealing. However, they are not easy to grow. If you want to enjoy these flowers, then it is essential that you learn how to remove their flower heads before they wither away completely!

The problem with most people is that they don’t even know what to do when it comes to removing the flowers from their plants. There are many different methods and techniques out there, but none of them work for everyone. So, I decided to write this article, which will hopefully provide some useful information on how to remove the flowers without damaging your plant or causing any harm at all!

What Is A Sibilant Flower Head?

A sibilant flower head (also known as a “dead” flower) is a type of plant stem that doesn’t produce new growth. Instead, it simply dies down and eventually falls off completely. When you see the dried up husk left behind, it’s because the plant has died due to lack of nutrients. That’s why you’ll often see sibilant flowers in nurseries where they’re used to make fertilizer!

How To Deadhead Siberian Iris?

There are many different ways to deadhead Siberian irises. The best way for you really depends on what options you have available to you (as well as your desired end-result). These are the most common types of deadheading that people do:

1. Use A Scissors

This is the simplest way and all you need is a pair of scissors. You can use these to cut off all the dried up pieces of the stem right down to the base of it. It’s important that you don’t try to cut anything above the top of the soil, or you could damage the roots.

2. Use A Knife

You can also use a knife instead of scissors. Just be careful when using something sharp around plants; otherwise, you might hurt yourself in the process! If you do decide to use a knife, it’s best to wipe it off before handling your plant again.

3. Use Drought Grown Technique

This is a slightly more complex way of doing things. For this, you need to make sure there are no flowers or buds on your iris before the springtime. After that, you have to water the plant a lot less than what it usually requires.

The plant might wilt a lot, but it will re-sprout! Eventually, the plant will go into a type of hibernation and produce a large number of leaves. The next springtime, you should be able to see flowers again.

4. Use A Root Cap

This is one of the best ways to remove the dead parts of your plant without damaging anything else. You can buy these online or even at your local garden store. Just follow the instructions that come with your root cap and everything should turn out great!

Are There Any Other Methods?

There are many other ways to remove dead flowers from your siberian iris without causing any damage to it! One of the most common ones is to simply wait until it is completely dead, at which point you can cut it off at the base. However, if you do this too early then you run the risk of damaging new growth that’s forming. If it’s too late then you’ll have to wait a while for everything to “settle in” before you can divide the clump.

Another common way is to use an ice cream scoop; just push it into the soil and wiggle it around. This will either break off the stem or simply scoop it out without harming anything else. If you aren’t able to do either of those, then your last resort is to pull it out by hand (this isn’t recommended due to the risk of damaging the roots).

What Is Divided?

Siberian irises are able to reproduce both by dividing the clump as well as seed. Once you have deadheaded them, and they have gone dormant, you can either separate the bulbs or divide the clump. To do this, use a shovel or spade to cut through the middle of it. Try to make each piece as equal in size as you can. After this, dig a hole for each piece and drop it in, covering it with soil. Water each one to help them settle in and then leave them for the winter. This is all you need to do if you want more siberian irises, otherwise, come springtime you can plant something else in its place.

As for seed, the flowers will naturally scatter these when the weather is right (usually early summer). Just make sure you don’t deadhead them before this, otherwise you won’t have flowers and seeds. Once the flowers have gone, you can cut them off at the base of the stem.

The remaining capsule (seedpod) will then open up to release the seeds which can be sown in early autumn.

In conclusion, deadheading your siberian irises is an important part of their life cycle. They do not like to produce seed if they haven’t got enough energy to survive, so removing the dead flowers helps to ensure that they live long and healthy lives.

Happy gardening!
