"In the spring when the Lilies are 1" to 6" tall you put down Beyers Grub Killer around all lily bulbs .
I did it once in April and again in May i only saw about 7 or 8 in April and i got rid of them by hand.
All of my lilies have come up this year and are just wonderful and really big."
I have to point out that grub killer is not available throughout much of Canada, including all of Ontario and Quebec, due to a cosmetics pesticide ban. Where they are available, pesticides should be used with caution, following the instructions on the label.
