Q.Primrose
Will the plant die if exposed to direct sunlight all day? I have them in my garden which is part shade and part sun, I have tried to plant them around my front light post which is sun all day but they die after about a month. I have tried doing this for the last two years with no success. I use the very best potting soil. I even removed all the soil and replaced it with fresh soil but they still died after a couple of months.

Full sun would not be a good location. A dappled sunlit area of a garden is best.
