My mother has a 5ft standard drooping willow in a large pot, she has had it about a year and has watered it reliably.
Last month it suddenly developed a lot of brown leaves, all went totally brown. It now has lots of fat buds and new leaves starting to shoot ot, and more worryingly, quite a few 'girl thingy willow' catkins, at this time of the year! She says she has been watering it regularly (she uses a moisture meter so I have no reason to doubt this!) and fed it once last month with growmore granules...any idea what might be wrong? Should we be worried it is flowring now? ???
