Hi there, help,! Nerine lillies..?. The picture you see could have been taken in 2013 and it still looks the same now in 2015 they have never flowered. I know about adding the right feed for flowers , still no luck. The question is should I cut the leaves right back or leave them alone .yours in anticipation jp.

One should never cut back the leaves of any bulb, until they are brown and dried.
Non-flowering of Nerines is all down to ripening of the bulb. They need the top half of the bulb to be out in full sun and baked in Summer to initiate bud formation.
