When to dig Dahlia bulbs

Hi,

My neighbour wants to know when can she did her Dahlia bulbs. They are still blooming and look lovely.

Thanks,
Millie

I seem to remember that you wait for the first frost to hit and damage the growth. Once that happens dig up the bulbs and store.

C/P from Dahliabarn.com :

Digging Dahlias

WAIT FOR YOUR DAHLIAS TO FREEZE IN THE FALL !! Then wait at least 1-2 weeks before you dig them up. Leave them intact and don't cut them down. Wait until the foliage has turned black and have completely died back. During this time, the dahlia is 'ripening' and preparing itself for winter. Dahlias dug too early will not store over winter. After the foliage has died back, cut the stems to a height of 6"-8". Use a shovel or pitchfork to gently loosen the soil and lift the clump out of the soil. Tap off the soil from the clumps and allow the clumps to dry in an area above freezing for at least 3-5 days. You can divide then or leave in a clump and divide in the spring. Then store for winter.
Do I really need to dig up my dahlias?
Digging and dividing will keep your dahlias returning year after year when they are dug and stored properly. Dahlias left in the ground will create a massive tuber clump underground that will send up many weak, unproductive stalks that have small blooms. Eventually, if left undug year after year, they won't come back at all. You can treat your dahlias as annuals and purchase new tuber stock each year.

If you live in an area that does not have harsh, freezing winters, your dahlias may survive winter without digging. In the fall, wait at least 1 week after a freeze and after your dahlia stalks have died back completely. Then cut the stalks down to the ground and place a 10"-12" layer of mulch such as grass clippings, leaves, straw or compost. This will protect your dahlias over winter. In March, remove the layer of mulch so that the soil can begin to warm up. Dig up the tubers, divide, let dry for 3-5 days, and replant them when it's the correct planting time for your area.

Although, we do recommend digging, dividing and storing in the fall, you should have success with this method as well.

Hi Millie, nice to see you are back. About the Dahlias,,I agree with most of Dave's comment but I dig mine a couple days after frost. We had a frost that killed the Dahlia foilage about ten days ago. I dug them 3 days later and cut off the stems. The tubers are still in the garage , I might leave then there for the winter as it doesn't freeze in our garage. I also don't wash the tubers, I leave some soil on it helps to not dry out the tubers. I have good luck in keeping any Bulbs, Tubers or Corms over the winter.

Gee Brenda, didn't see your post until I went to print this. That's actually what I told her but both Dave and Clara have supplied plenty of info.
Thanks for your response.

My 3 dahlia bulbs were dug up and dried out about 3 weeks ago, as we had killing frost in mid September here in PG. They are now sitting in a shallow tub with some vermiculite spread around them. I have 3 enormous Skaugum begonia bulbs drying under my dining room table, and they will get put into the basement in a similar fashion.

I don't have a good safe cold zone in the house which has a finished basement (no garage), but I put them in the space under my stairs which is the coolest. I use the vermiculite to control the moisture which has worked better than just leaving the bulbs in the tubs on their own.

Bye the way, it is currently snowing in PG, and my tire change appointment is tomorrow! I don't think it will stay on the ground, but it startled me to look out the window while cleaning house and see the white stuff!
