also when can i move dahlia and gladiola bulbs to abetter position for next year

leave until autumn when the foliage has died down. The bulbs need the nourishment from the leaves to produce good flowers net year

Do you normally lift your Dahlias tubers for the winter? After the first frost is the right time, when you can still tell where they are!

Then in the spring you can start them off again in trays or pots and plant them where you want them.
