I planted my first ever Dahlia's this year but they were too tall for the boarder i put them in. Well next year i'm building a big boarder in my back garden but won't be ready for the start of next year to replant. Can i store dahlia tubers or do they have to be replanted every year?.
Also 2 kinds of dahlia's i planted this year had 1 or 2 flowers that didn't look like the other flowers, does this happen.
