Why has your agapanthus not bloomed this year?

Answer 1

If planted indoors in a pot:

Needs to be somewhat root bound to bloom. Feed it once per week with a fertilizer high in phosphorus. Soil should not be soggy. Needs plenty of sunshine.

If planted in the ground:

Feed with a fertilizer high in phosphorus. Make sure the soil is well drained. Agapanthus do not like to be disturbed. If you planted them recently then it may take a year or two for them to get adjusted to the new environment. The larger the foliage clump the heavier the blooms. Once adjusted they will thrive in most conditions...but never below 20 degrees.

Answer 2

It is likely because it's lacking light or the plant has been left in draught after previous flowering and didn't have enough energy to build flower buds for next year.

Answer 3

One reason why an Agapanthus may not flower is because it is getting too much water. Try letting the plant dry out between watering to see if that helps.

Answer 4

The most likely reason is too little light. Agapanthus will flower when the soil is quite poor, so it is unlikely to be lack of nutrients.
