I
think you might have some success tranplanting the way I have been doing it this year. I have moved about 35 volunteer tomatoes and I just removed, reBEDDED and put back 4 geraniums, 4 petunias and 4 lobellas--I have a red (geranium), white (petunia) and blue (lobella) theme--next to my front walk. THIS is how I did it with no damage.
1) Dig around the plants carefully so you don't touch the roots, just the dirt around them.
2) Carefully place the plants in a bucket or big pot that holds the plants and is 1/2-full of water. This keeps the roots moist.
3) Till (hand or other) the new planting area thoroughly so there is room for easy new root growth.
4) Dig with a spade a hole bigger than needed to replant.
5) Place the plant in the hole and hand-fill the dirt around it.
6) Water thoroughly afterwards, until you see new growth.
In MY case I have to avoid over-watering the geraniums bc they like it dryer and have deeper roots--These are the ones I over-wintered in my upstairs windows--than the annuals that I bought.
Hope this helps!
