Hello to you all, apart from digging out the tubers, last fall I tried something else with a group of not so worthy dahlias ( we all have some with which one can try out new "perhaps" techniques). I lifted and repotted them in dryish sandy soil in 15 cm x 25 cm black polythene plastic bags and left them inside my cool greenhouse in a shaded end. The soil was kept almost dry. This spring ( about three weeks ago) this group of about 14 , timidly first and then quite vigorously later, sprouted . I moved them to a very sunny warm greenhouse and are probably going to be the first to go out. In my scheduling, potting tubers is part of my chores. Doing this in fall may save precious spring time, specially since there is little pressure in fall as everything gradually goes dormant. Of course this means that the clumps are lifted in one piece. I'll try out this with division included next fall on larger clumps. Once again we'll see.! Probably if this has good survival chances, then it may well serve for smaller tubers ( i.e Bishop's Children cvs.) or those that are more difficult to handle, once they are out of the ground. Thanks Arturo
