Red Star Hypericum Inodorum Komarest Has Dry Leaves And No New Ones Appearing

Question From: Plainfield, Illinois, United States
Q: Last summer I planted a Red Star Hypericum inodorum Kolmarest. It was lovely all summer and fall. However, now it has dry leaves and no new ones appearing. I did give it a little trim. However, I think it is dead. I am not sure why. Perhaps it died this winter. I have searched the internet for more info but cannot find any reasons. Can you give me any ideas? Thank you.

A: Later season fertilizing, too much fertilizer, lack of water, too much water may be reasons. Those would be my guesses. Best And Happy Yardening, Nancy
