I am thinking that the sweet potato might put out some more growth, but not sure where. All the Goji’s are putting out new leaves from the bottom except 1.
Obviously, I am just a newbie on sunflowers, so I don’t know.
As long as you have 3 or 4 regular leaves on the tomatoes(most plants in fact), you can transplant. Why not do some now, and some later to see what works best for you?
