Do dahlias come back every year?
At the end of the growing season, you can either treat your dahlias as annuals and plant a fresh batch of tubers next spring, or save the tubers from the varieties you really like and grow them again next year. They will start growing again in spring.
How long does it take dahlia tubers to sprout?
When you are planting dahlia tubers, you may or may not see a sprout. Often, the tubers don’t sprout until they have been in the ground (or in a pot) for 4 to 6 weeks. It takes tubers longer to come out of dormancy when they are planted early in the season and the weather is cool.
How do you wake up dahlia tubers?

How can I tell if my dahlia tubers are dead?
It’s easy to tell if the tuber is rotten to the point of ‘death’ since you’ll be able to feel a soft spot. You may also notice visible mould growing on the end of the tuber; by squeezing it gently, you’ll be able to tell whether this is just surface mould, or something that runs deeper.
Can I plant dahlia tubers without eyes?

What is the difference between dahlia tubers and bulbs?
First, there is no difference between what people commonly call dahlia tubers and dahlia bulbs.

They are made of undifferentiated tissue.
