I bought 2 Agapanthus plants at a garden centre 4 years ago and I planted them in garden and had 1 flower on each the 1st year but only had green leaves and no flowers since,could you tell me reason for this and what I should do to get flowers on them as they are lovely plants.

Agapanthus took a knock of frost two years ago and plants have taken time to recover so this is a possibility.
The plant needs well-drained fertile soil in full sunshine and, ideally, some shelter to increase summer temperature levels.
A light top-dressing of general fertiliser in spring or feeding with liquid plant food in early summer can help to boost growth and flowering.
