We just did a half dozen mixed Dahlias along with a handful of other bulbs, and they are by far the most vigorous. They have leaves out and are reaching up more by the day.
I wasent expecting a bloom this year, but watching them go, we might get one.
They are stunning, and we're the last thing to die last year. Once they get going, they are fantastic. Be sure to pinch the tops off the young plants to get even more growth as well
I love me some dahlias, but removing the tubers every year isn’t easy and risk them dieing easier as well. I’ve just been buying new bulbs every spring, I’ve still got some from last year to plant with them though.
It was surprisingly easy and pain-free for me, I didn't do anything special other than dig them up and throw the clumps in a storage bin full of vermiculite in my basement. The only hard part is dividing them because I had no idea what I was doing this year. It would much less work of anyone who lived somewhere warmer, but I am in Alberta, and it's too cold to overwinter them
