I'd suggest starting with the Swan Island Dahlias site. It where I bought my first tubers and has lots of good info on growing them. If you have specific questions you can run searches on this forum, there is a huge amount of information here, you just have to sift through it.

People grow Dahlias everywhere in the US, the Pacific northwest seems to be where most of the professional growers are, but I have seen great Dahlias everywhere from Alaska to Florida.

Here is a link that might be useful: Swan Island - how to growâ¦.

Mark,

One issue to be aware of is that while dahlias are technically perennials, the tuber they grow from cannot be allowed to freeze. In your climate you should plan to either dig the tubers up at the end of the season or just let them freeze and plan to buy new tubers next season. Also they don't like intense heat (it will cause deformed flowers) so if you can plant them in a location where they will get afternoon shade in midsummer that would be beneficial.

Thnx for the information.....

Last fall I wrapped my dahlia tubers in newspapers and put them in paper bags. I checked them in January and they looked okay. Yesterday I checked three of the tubers (I have 16) and they seemed dried up. I put the three in water overnight. They appeared a bit better this morning. I have them drying off before I wrap them again. I have to take a look at the remainder. Should I do what I did or something else. Any help would be appreciated. Maxyck

Maxyck, I don't think that wrapping tubers in newspaper is such a good idea. As you have observed they will lose too much moisture.

There is excellent information about digging, dividing and storing dahlias on the web at the following link:

Another storage method that I have used successfully is to dig the entire clump and pack it into a 5 gallon bucket surrounded by regular garden soil. It is fine for the soil to have a little bit of moisture but you certainly don't want it to be water logged. I store the bucket somewhere where the temperature will stay cold but not freezing during the winter. You can divide the clump in the spring or replant the whole thing.
