How to divide dahlia tubers
It’s so satisfying to see your plants finally in bloom!
We know it can be a bit scary when you’re first learning to divide your dahlia tubers, but have no fear! Once you learn a few key tips, you’ll be ready to get started working on your own clumps. The only way to gain confidence is to just dig in and start practicing. After doing a few clumps you’ll feel more comfortable and will be ready to tackle the project head on!
We made a short video that you can watch here to show you our process for dividing dahlia clumps. Remember for a tuber to be viable for planting next season it needs to have both an eye and a strong neck. The eyes will only be found at the top of the tuber, on the crown, where the tuber connects to the stem. Keep in mind some tubers will not have an eye, so those can either be left connected to an adjoining tuber, or can simply be cut off and composted.
Remember that you don’t need to divide your clump into individual tubers, you don’t even need to divide it at all if you really don’t want to. But I do recommend that you at least half or quarter it to keep your dahlias more vigorous and the clumps more manageable. You can simply cut the entire clump right down the center and plant it like that. You may lose a tuber, but it’s nothing to worry about.
Let me know if you have any questions- I know it can be a daunting task at first!
