To my surprise Monty Don said on last Friday's GW to throw shrivelled dahlia tubers away!? Can't understand why he said that, because my tubers overwinter in the cellar in a box all by themselves (no compost or newspaper, etc.) and are shrivelled every Spring. In April/beg. May I soak them in a bucket of water for a day and then plant as usual. Haven't had a failure yet, they always come up beautifully.
