Digging, Dividing & Storing Dahlia Tubers

By frankrichards16

In the colder climate zones, dahlias have to be dug up in the fall and stored for the winter. I have been digging and storing tubers for many years. I have tried many different methods. Here is what works best for me.

Thank you for making this simple
I just had my first frost last night and expect a freeze tonight.

One question what if we head into very cold weather ? can I mulch heavy to leave them in the ground for 2 weeks? or do I risk freezing the tubers?

I would just dig them up. Waiting for a couple of weeks just makes it easier to see next years buds, makes dividing easier.

Hello Cinda, perhaps you might consider that the chances for your tubers freeze in the ground are very low when the first frosts arrive. The soil is quite warm from the summer temperatures. In soil temperature graphs the peaks in the upper foot or so, are surprisingly in fall rather than summer, because soil temperature keeps building up.. the coldest temps only in early spring. The idea of helping the tuber develop their next years buds in the ground as they probably did originally in nature in their high altitude native Mexico, is something I had overlooked and I'm very grateful for Frank's advice. I also lift my tubers although I tend to have milder winters., but some may be unexpectedly cold and if I left my tubers in the ground I learnt by the hard way, they are gone. Here in the southern hemisphere we are planting our dahlias. I start them indoors in pots and move them out in about a month's time. Yesterday I finished potting all of mine. All the best Arturo

Wonderful!
Thank you Frank!
For the first time I have a dahlia that I like so much I was wondering how to go about trying to save it--perfect timing indeed!
I'll give it a try Smiling

Thank you, Frank.

This is my first year growing dahlias and I want to save the tubers. Your instructional article has step-by-step details and photos that visual learners need.

I would like to store mine in the craw space, and I need to know how warm will tubers tailorate without sprouting. I know that the space stays under 60° and above 40°.

@profesora

a crawl space works great for tuber storage.
