Joking aside, I don’t know about Dahlias, but I know there are many plants that you have to take extra precautions when transplanting, such as waiting till after bloom or during a certain season. Could be over/under watering. Like I said, I don’t know Dahlias, but those are some starting points till someone with the knowledge shows up.
You got $30? Some of us are so poor that even $30 has to be planned and budgeted for. And most places want all $30 for the year up front and won’t split it up into monthly payments. Not everyone can just plop down $30 at a moment’s notice.
