Growing Dahlias from tubers and excitedly daydreaming about how many flowers you might get come summer? You will want to know how many dahlia flowers you get per tuber? let’s have a look and find out.
How Many Dahlia Flowers Per Tuber?
To start with different varieties of Dahlia produce more or fewer flowers than other types, this is one factor that is completely beyond your control.
Then you have the weather conditions that particular year if we have a really sunny hot summer then you can expect many more flowers than if we have a cold wet summer.
So now I have talked about the factors outside of your control let’s have a look at what the gardener can do in order to get more flowers per tuber.
The main thing is regular deadheading or cutting of flowers. If you are growing your dahlias to use as cut flowers and are regularly cutting them off the plant then you will end up with many more flowers than when they are left to grow naturally.
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.
Another factor that will greatly affect how many flowers you get off a single dahlia tuber is how often you feed them.
If you can give your dahlias a good feed once per week throughout their growing season then you will get many more flowers off a single plant than you would if you left them to their own devices.
This is the feed I use for everything in my garden and allotment, just dilute it down in a watering can and away you go.

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 being unable to survive winter outdoors in most of the UK, they 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.
