Tracey, sorry to seem over pedantic but they are corms not tubers. Ok, who cares? We all know what we mean
Dahlia tubers. Begonia corms. And yes, you can keep them from year to year and they will produce bigger and better plants. Keep vine weevils away and keep warm and dry over winter though.
Yes, delay planting for a while yet. The corms are started into growth in trays...for me anyway....and when shoots appear I pot them up.
Hope this helps
