Hello everyone, Just bought this St. John's Wort last year. Ever since then it hasn't grown an inch. It just stayed the same size like in the picture. I planted it in front of the hydrangea, it gets full sun at least 5 - 6 hours. I also noticed that some of the leaves are turning yellow. Is this part of the problem? I water it every 5 - 7 days if it doesn't rain that much. Your suggestions would greatly be appreciated. Edmond.
