Answer: Ipomoea, or Moonflower seedlings don't like to be disturbed so the act of transplanting may have set them back a bit. But, this should be just a temporary situation as the seedlings adjust and recover. Moonflower plants need full sunshine to perform well. That usually translates into 8-10 hours of sun each day. The spot they're in sounds like it gets less than half that amount, which could account for the lack of growth and bloom. Moist soil is a requirement, and you're taking good care of that. So, unless you want to move them, they probably won't grow as vigorously as they might under different circumstances. Try pinching out the tips of the stems to encourage new growth and don't fertilize (plants do not require it and they may sulk even more!). Hope this helps!
