I had lily beetle for the first time last year and grow lily's in pots. At the weekend the lily's were repotted which left a couple of bags of spent compost which I was thinking of taking to the allotment to help fill a raised bed. I don't plan to grow lily's on the plot.
Silly Q time, does the lily beetle infect any other plants as it's possible their eggs are in the spent compost and I don't want to introduce a pest to the allotment. The neighbouring sites just grow veg and no flowers.
