Question: Two years ago I rooted cuttings of Hoya carnosa and put them in a pot. They’ve sat in an east window for two years without making any growth. What can I do to make them grow? RB, Mass.
Answer: I have waited two years for leaf cuttings of Hoya carnosa to grow after rooting but stem cuttings usually grow quicker. Perhaps if you shook them out of the soil and potted them singly in small pots, they might start after a while if kept in a warm humid atmosphere.
