I bought a large 'Elaine' Agapanthus and divided it into 4 plants. All four survived the winter in an open unprotected, unmulched full sun location. I realize this was a mild winter so I transplanted them to a more sheltered location in the spring and they have grown very well but no blooms this year. I have since been told that the roots like to be crowded and they will often bloom better if potted or even buried in the ground pot and all. I may dig a couple up, put them in a pot & re-bury them as an experiment for next year. This past weekend I purchased 'Peter Pan' & 'Lilliput' Agapanthus which I think are smaller varieties, so we'll see how they do and if they survive this coming winter. Squirrellypete

From much further south: on the nearby Agapanthus there are yellowing leaves and old flower stalks. Deep in the leaf clumps there are snail casts. However, there are no white deposits at all. We have had a couple of mild 1-2degree frosts and it's been hosing down for all of June. The plants in question are on a clay-loam that was pasture. They're competing with a variety of tree roots and are trapped by a fence. The clumps are very congested. They get half-day sun and flower reliably. They are the evergreen kind of Agapanthus, not deciduous. If you're in the NSW drought zone the plants may be feeling the pinch and have become host to something like mealy bugs. First shot at eradication - Lux flakes melted in water and poured on with a jug. Some cayenne pepper mixed in could be useful, too. If the edges of your clump are still healthy you might want to take some pieces and pot them up, as insurance. If you think they could be droughted and you're on water restriction, you could use the rinsing water from your washing machine to really soak the area. You should get about 60 litres from one wash load - enough to improve the water availability for the plants.

I'm living in New Delhi too. I brought an Agapanthus from South Africa in December 2017. I planted it in a pot and it flowered in a couple of months. There are no flowers presently, but it continues to look fine in the pot. I will be happy to communicate with you on this. My email address is pulse.abhay@gmail.com

None, other then there being more plants surrounding the one that is doing well. I am worried maybe the one that is dying needs more soil?
