Sweet Caroline Ipomoea cuttings growing in peatmoss based growth medium in greenhouse that are supposed to be chartreuse have reddish tinge and some reddish veining, but otherwise seem healthy. What fertilizer or other supplement do they need? They are for use in hanging baskets.

    If they are in a peat mixture, then it is likely that they do not have any nutrients at all. Any well balanced fertilizer will be fine. If you were to replace the peat with potting soil, then you will not need to fertilize at all. They are not heavy feeders, as they have edible root storage for nutrients. (These are sweet potatoes, essentially!) If you choose to leave them in the peat, then they will need a weekly half strength liquid fertilizer. Any 10-10-10 will be fine
