I've been de-potting and planting things up in ground a lot lately, pretty much all cacti. Had some loads of soil delivered too for the landscaping.
I've noticed a lot of curl grubs in some of my pots as I depot them and am teasing out the roots.... I bin the soil and grubs when I find them.
Seeing small numbers of grubs in the fresh delivered soil also worries me a bit. Google tells me they are the larvae of the Christmas beetle... We get Christmas beetle here prolifically in summer.
Apparantly they don't like deep moist soil, dry top layer is where they lay there eggs. Google says they fuck sections of lawn easily, and can devastate pot plants.
I haven't noticed any huge reduction of growth or damage as a result (not that I'm hugely experienced). They shit me none the less...
Any stories of curl grubs from any SABers? are they a terrible menace, or relatively harmless?
Any decent organic methods of getting rid of them? Or even chemical methods that aren't too harmful to the cacti etc?
