I have never attempted to grow dahlias before. At rose garden plant swap, I contributed many stalks of rhubarb and was given 4 tubers by one of our members.
He suggested I plant them close together, 2 x 2, so they would have support and as yet have not had to stake them.
I asked what colours and was told..."just wait and see, they are mixed colours".
These 2 are between the apricot tree and a standard rose.
These 2 are on the other side of the apricot tree next to the dwarf orange.
This stem has 3 buds.
It will be a trial and error theory, like Bill said, just wait and see.
So far so good.
