I have a large flower garden which gets shade 80% of the day. I have had this garden for about 5 years. I have begonias, hostas, other shade plants and impatiens. This year my impatiens are not growing very much and have yellow leaves with brown spots. I have tried miracle grow and they seem to be worse. Other flowers and plants are doing well. I also have some hanging baskets in same garden with impatiens and they look great. Any suggestions would be appreciated...........thanks
