That is my favourite dahlia, growing in the chair in the picture above! It's a 'Keri Blue', called that because of the slight blue tint in the very center. It's beautiful and I take no chances with these during their winter rest in my cold cellar. Also wintered over in the cellar are other dahlias, cannas, glad, 4 O'clocks and geraniums (pelargoniums). Many winters, if left alone, the small dahlias will dry up. Some of the other ones do too. This has always been a great disapppointment to me in the spring!
This year I decided to take steps to make sure that didn't happen! I read that it helps to take them out of storage in early January and soak them for a day or so, then dry well again and pack in cold storage for another couple of months.
I did that this past week. I took out the small dahlia divisions and small new dahlia bulbs, as well as the 4 o'clock roots and soaked them in room temp water for a few hours. I then laid them out on the kitchen floor on newspapers to dry for a few days. Today I repacked them in wood chips in plastic bags in the basement.
I had planned to leave them for a few more days but our wonky male cat, Shadow, who has cabin fever in the snowy winter, spent his morning attacking them and shredding the papers. lol! Since they were dry again, I put them away. It won't help him. He just attacks the little rugs and the furniture, rolling around on the floor and killing them with all four feet and teeth! lol! Abby, the female cat, prefers to play with and carry off any little hard things she finds around. Anything is fair game. Hubby swears that she has stolen a couple of his tiny wrenches from the desk. I have seen her batting other things to the floor and knocking them around, as well as finding wood pellets scattered all over the house in the morning! (I won't be the only one glad when spring comes! lol! We love them both dearly!)
I only soaked the small and new dahlias that would, in past years, be dried up in the spring. In past years I have tossed them down there to be completely forgotten until spring. This year I have new ones that are important to me, so I am tending them carefully, checking on them whenever I am down there and making sure they are not getting shrivelled.
The geranium roots are hanging up, dry. This is the first year I have wintered them over in this fashion. Usually I pot them up and grow them as houseplants all winter, and I did do a few like that, also. Geraniums love spending their winter growing in a sunny window and bloom continuously, right up until they go outside in the spring. I didn't have room for all of them this year. I am considering soaking the bare geranium roots hanging in the basement, too. Has anyone done this and does it help or will they be fine hanging bare root in the cold cellar until spring without intervention?
I had calla lilies and some dwarf white cannas last year, but neither survived last winter in storage. I grew them all from seed and was very disappointed when they didn't make it.
