Has anyone else noticed their bay trees slowly declining in health? Mine were all perfectly healthy up until mid March, now one standard bay and three smaller bay's are slowly developing darker crunchier leaves, and slowly turning brown! I protected them through the harsh winter conditions, and they starting sprouting new growth at the end of Feb/beginning of March. Does anyone now what it could be, or have you experienced a similar problem? ...and more importantly is there anything that I can do to revive my beloved bays?! Thank you
