Major lilly problems

Hi everyone, I have some garden Lilly's that I've had for around 10years. Their foilidge is green, lush and healthy. However the flower buds that have developed are brown in colour, shrivelled and a lot smaller than usual, the same happend last year, the flower does not grow nor does it open and just falls off eventually. There is no sign of pests on the plants lilly beetle etc, nothing. However I have sprayed it with insecticide and gave them a good feed and doesn't seem to have helped, exactly the same as last year. Anyone got any advice for me??? Help image

    I think I'd dig up one of them and have a look at the bulb firstly, see if it looks ok. There are a number of things which can affect lillies, but your description doesn't seem to fit any of them. I'm no lilly expert but like most plants they have a life span. It maybe they are getting old and have had their time.

  • Cheers Dave. Maybe they have had their time image if you can think if anything else I could at least try then let me know!
  • are they lilies or hemerocallis - day lillies?

    if the latter, mine grow fairly dry and like to be in the sun

    It might be lack of nutrition and they may have exhausted the soil around them.  That happened to a large container of my lilies one year and when I re-potted them into new compost with extra fish, blood and bone, they gave a magnificent show the next year.

    If they are in the ground, a good 3 to 4 inch deep mulch of well-rotted farmyard manure this Autumn should get worked down by the worms in time to help for next year and may fix the problem.

    A trowel in the hand is worth a thousand lost under a bush.
  • Not sure what type of Lillie's they are I'm afraid. They are in full sun in South facing garden and I don't over water them. They're in the ground not in pots. Cheers Bob I will try that in the autumn then. I did put a top dressing of organic manure in the spring but it hasn't helped.

    If they're Day Lilies rather than 'real' lilies then they might have Hemerocallis Gall Midge which affects the buds - see this thread
