Hi,

I planted three lilium flowers some time ago and they have grown into nice plants with flowers waiting to bloom. A couple of weeks ago, the leaves on one of them started turning brown at the edges and curving a bit downwards instead of staying firm as they used to be (as shown in image Plant 2). Last week, the second one started showing the same symptoms. Any idea what could be the cause please? I did not change their location or anything - only thing that changed is that it got hotter but I am watering them as required. The first one which was showing the symptoms has now died completely (as shown in image Plant 1). Any idea what could be the problem please? Thanks.
