Depends on how well draining your soil is
You might still see some loses, you want the plant to have a fair few tubers, just in case.
Mulch heavily if you are leaving it in the ground and don’t stress.
It`s going to be standing in the wet that`ll do for it as well as cold. I`m on heavy clay so I`d be digging it up and storing it. YMMV
Last year, first time ever I dug up the dahlias bar 2 . Treated, wood shaping dry and cool.. all moulded and rotted. The 2 left was wet and cold.. they made it..
I leave them in and as long as I remember to put a deep mulch on them, I would only expect to lose some in a terrible winter. But I have well-drained soil, if not, I would lift them.
I grow mine in pots so I dig them out for winter.
If they were in the ground I still think I’d dig them out as I’ve got heavy clay.
I mostly leave in grown apart from the wet areas. But also grown some every year from seed so I don’t worry at all.
Collect seed off them, they are so easy to grow from seed and flower the first year. That way it doesn’t matter if the parent plant dies off
Dig them up and store upside under cover.
Thanks for asking. OP. Does anyone know if molluscs are more likely to eat roots over autumn before spring if the dahlia are left in the ground?
Lift not so much for the frost
But the next year I can start them again in pots and keep them away from the army of snails/slugs
Also gives you an opportunity to divide them and end up with four times as many plants next year
Don’t have time to do either, slugs have mine before they even flower. Next year is going to be the last time I try dahlias in my garden, if they fail then that’s it. Shame, because they are lovely flowers.
I mulch mine. I did have 5 originally and only have 2 left.
We mulch our main ones and they always boom back – smaller ones that are originally part of a summer bedding display we often preserve but have a lower success rate with (we lack facilities to keep them properly dry is the issue I suspect)
I’ve always overwintered in the ground and never had an issue. Though I have two very unhappy ones im going to dig up tomorrow and winter in pots this year
The last time I tried dahlias the snails got them before flowering too.
I lift and store them mainly because the slugs would eat all new spring growth. I pot them in spring and grow them to a good size is pots on racks off the ground before planting them out.
Neither, just leave the ones in pots as they are. Might chop down the above soil growth if I want to stick in some winter bedding.
If it’s a wet winter though? 🥴 it’s the wet that will rot em! Mine are in pots, I got a non hardy fushia through last winter in a pot, in a sheltered spot that was covered and I wrapped with bubble wrap around its pot. I might just do the same with the dahlias!
My first time with dahlias. I swore I wouldn’t get any because I have nowhere to lift and store, but I got 4 big sorry looking plants from B&M for £1.50 each and they are now massive and beautiful dahlias that I would be gutted to lose. 🥴
