Arum Lilly Leaves Browning From The Edges And Not Flowering
Hi I have a few Arum Lilly plants in pots on my balcony. This year I'm having a huge problem as the two flowers that did emerge didn't even open and just died on the stalk. Just about all of the leaves are slowly dying - turning brown from the edges. I've been removing all of those as they started but I'm left with only a couple of leaves. Even the unopened leaves show signs of dying on the tips. I don't see any sign of insect infestation. What could it be?

There are a few causes for this, but usually it is due to lack of phosphorus and potassium, or too much nitrogen.
Other causes can include low humidity, low temperature, and dry soils.
