i understand that jeyes fluid is effective to kill the vine weevil grubs. nobody seems prepared to suggest a dosage though. budleigh in bloom have many troughs, one of which i recently discovered was riddled with grubs.i don't want to overdose.
Jeyes Fluid will kill your plants as well as the grubs. You can buy products that will only kill the grubs in any garden centre but they are more expensive. You could try taking the plants out of the pots, rinsing off the compost and planting up in fresh material. Put the old compost outside and the birds will recycle the grubs.
we have several hundred begonia corms. . when i was removing the compost by hand, i noticed the grubs were in the crown of the corms. i removed all those that i saw, planted them shallow in fresh compost in polystyrene boxes to winter in my greenhouse. i note that some of them are sprouting already. i don't want have my greenhouse invaded by vine weevils. it was recommended to me that i should drench them with a solution of jeyes, but don' know what strength to use. years ago, i found it quite successful to dust with green sulphur . that would be very labout intensive. as we are an 'in bloom' group, i obviously want to keeps costs down.
I certainly wouldn't use Jeyes Fluid - it's completely indiscriminate and kills everything good as well as bad, leading to an imbalance.
Posy's advice is correct - use a specialist product but also remove the infested compost and leave it out for the birds to eat the grubs. Nature's way of dealing with it, and the birds will be thrilled at some extras at this time of year
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
