Absolutely. If you can protect them from freezing (probably not too much of a problem in Southern California) and rotting from too much moisture (again, probably not a problem for you), they should be just fine. I live in Portland, Oregon and have had some dahlias in the ground for -- I think -- 5 years now. They're underneath the overhang from my porch, ...


I did a similar thing with tiger lilies that were taking over my garden, although this is more accidental an anecdotal than it is scientific. I was digging up the tiger lilies and I threw them all into a black trash bag. I kept the trash bag in my tool shed, where it would certainly get very cold in the winter, and the next year I discovered them, so I ...


To confirm (check) your growing zone, plug your details in here: What is my arborday.org hardiness zone? Then read some top quality information from the Missouri Botanical Gardens: Dahlia (group) With both of those bits of information you should then be in a good position to make a well informed decision.


As far as I'm aware, Dahlias are perennials in USDA Hardiness Zone 7 and higher. In zone 6 and below they are treated as an annual. Instead of collecting seeds (which can be done, see below), it's generally recommended to dig up the tubers (roots) in the Autumn (Fall), clean them, store them, then replant them in the Spring a week or two before the average ...


I have dahlias in the ground here in ground in Chapel Hill, NC. They have been there for several years. If the ground does not freeze and if you have decent drainage (mine are in raised beds) they seem to be very reliable returners.


Your profile reports your location as Portland, Oregon, so I'll assume that's where the dahlias we want to overwinter are located. Let Dahlia tubers remind you of Goldilocks and the Three Bears--we don't want things "too" anything, we want things just right. Don't dig too soon, don't dig too late. Dig them up ten days or so after the first freeze or, if ...


Hmm, well I'm in two minds on this one. You've said its only one stem that's produced this sport, so I think I'd be inclined to leave the plant alone this year, then wait and see what it produces next year, which should give more time for the tuber which has produced these to get bigger and have more eyes (from which growth comes). You can take cuttings from ...
