Dead Heading advice

This question was asked by
Lynda W – 

My neighbour never dead heads her lilies. They come back every year strong and fabulous.
I DO dead head but often my lilies seem to get weaker and disappear over a few years.
Do you have any idea why this should happen? We have the same soil. The only difference is her garden gets more sun.

Hi there,

We always advise on removing the flower heads but to leave plenty of stem and foliage to die back naturally to feed the lily bulbs for the following year.
