Whilst checking my pots of Sempervivums, I found that quite a few of them
had lost their roots and looked very unhappy indeed. On closer inspection, I
found two white grubs had burrowed into the centre of one rosette, and worse
still, the soil in all four pots was infested with the blighters. This has
annoyed me greatly as I always use fresh, sterilised compost for my
plantings. No doubt the grubs must be the dreaded vine weevil, and I must be
more vigilant. What is the best method of getting rid of them these days?
