Hi,

is there a way to help a plant with fertilizer burn to recover?

The plants in question are agapanthus, and I know I over fertilized. The
leaves turned yellow and it;s not looking very happy at the moment.
Is fungus something I need to worry about? Should I continue watering? I
have cut the yellow parts of the leaves already.

Please tell me how else I can save them there is a whole row at the front of
my house, and I like them there.

Thanks in advance,
