Hi. I planted 20 emerald greens in the spring. All went well, no browning watered adequately seemed to be thriving. In August and September we had lots of rain here in New Jersey. (Lots) Now it's early October had all of them are turning brown from the inside out. There hasn't been much rain last couple weeks but I haven't watered them because soil is still moist. Please help, I don't want to lose them.
