I have tree lilies in both pink and yellow. The pink ones have bloomed perfectly but the yellow ones have started to flower but never bloomed. Any idea what I can do for next year.

hi and welcome to goy.
you could give them a foliar feed every 2 weeks until they start to lose their foliage.
you said they started to flower, did they fail to fully open? that could be due to lack of water.
