Mary Beth,
The suckers will perk up and loose their droopiness. After a month or so in the bag try tugging lightly on one of them. If roots are being formed they should resist the pull. If the suckers droop more and start to turn brown they're probably gone. Just don't be in too much of a rush to get rid of them. Sometimes they seem to rise from the ashes like a phoenix. Check them weekly to make sure the mix is not dry.

Hi Mary Beth

Dont forget light, plants , even suckers need light. I agree with fred pretty much on everything. Personally I tend to unbag them after 2 and 1/2 to 3wks and you can give them the tug test as Fred has said. Some people like to leave them in the bag , i dont. Still keep them moist with light, either good sunlight or artificial. I lost some before because of lack of good light. Good luck
