I apologize for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Either the roots are drowning from too much water, or the plants suffered some root damage in the planting process, such as the roots of drying out or being injured physically. Hopefully they have pulled out of the by now but if you end up having to replace some take care to firm the soil around the roots went planting and water than in well immediately. Then only water as needed to keep the soil moist.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
