Dahlia tuber

Zone 97267 | Crystal B added on April 3, 2018 | Answered

I used a dahlia tuber to propagate shoots in a box, then cut the new shoot and plant it in a pot. I wonder if the used tuber should be just disposed? Or is it still useful?

It is necessary to have, both roots and shoots on each division. If you are not able to do this, then the tuber is best left alone. This is a nutrient storage organ that is necessary for feeding the plants. If there is none left on the shoot, then it will likely die. Could you send a picture of what you are referring to so that I may help you to divide this correctly?
