I have left a large healthy Morning Glory (not sure if Ipomoea macrantha or Ipomoea violacea) slip in a cup of mineral water for it to take root. But I delayed to plant it for many days and now it is pale and burnt, but roots still looking pretty healthy and one big leaf still enduring. It seems able to survive, if properly taken care.
Now I have just planted it in a pot and my question is: is there anything I can do from now on to increase its chances of survival and/or to speed its health's recovery?
It took long for it to take root an I have cut it during a special occasion and from a dangerous place, so keeping it alive is highly preferable to simply trying again.
