As soon as you notice the blooms looking untidy or dying back then you can deadhead them. This will promote the growth of new flowers, allowing your dahlias to bloom even longer.

Deadheading Dahlias

As you should with pretty much all flowers, deadheading Dahlias is essential to getting the most out of these plants.

Deadhead spent blooms by removing the full stem with a pair of sharp secateurs or scissors. It can be tricky to tell the difference between a flower that has finished and a bud that hasn’t opened yet.

Buds that are going to flower tend to be nice and round, leave these well alone, spent blooms tend to be more shrivelled and have uneven shapes.

Here is a Dahlia bud that has not opened yet, you can see that it is fairly round. I picked one that isn’t perfectly round just to show you how if you are not paying full attention you could easily deadhead buds which were about to open.

Spent blooms will be a lot more uneven than this and usually have bumps and ridges in them.

More on Dahlias

Dahlias are simply stunning summer flowers, the pop pop head produces amazing displays. The plant is a member of the Asteraceae family along with daisies, asters and marigolds.

Usually grown from a tuber but they can also be grown from seed. The tubers require special care over winter here in the UK and many growers end up with an almost fanatical devotion to their dahlias.

Despite not being able to survive winter outdoors in most of the UK they actually thrive in our summer conditions. The moderate but wet climate we have is absolutely perfect for them.

Dahlias make the perfect container flower and are commonly grown this way. Growing them in containers also makes preserving the tuber over winter a lot easier.
