QuestionsHow to growFlowersBulbsDahlias 0 Vote Up Vote Down Don Foley asked 9 years ago Is it too late for me to plant Dahlia tubers in pots? Those I planted directly in the ground have been destroyed by slugs/snails. I thought I might grow new tubers in pots and plant them out when they are mature.

It is too late to start tubers off and they are probably gone from the shops.
