And now.... vine weevil

[Lardman]

I'll admit to wondering why I bother more than a couple of times lately.

One of the potted blueberry bushes has been getting progressively sicker despite my best efforts. I've tipped the pot out this afternoon only to find it a teaming mass of vine weevil grubs.

I've cleaned what was left of the roots off with the hose and repotted in multipurp (nothing else handy) but I don't give much for its chances, annoying as this was the first year it would have given berries.

I swear I think I've got just about every pest known to man.

vine weevils are a real bugger - sorry to hear about the problem.

I feel your pain - I lost loads of young cuttings this year.
Does sinking the pot in the ground deter them?

I feel for you. Not only are vine weevils a pita, but they seem to know which plant to go for that will hurt you the most.

For me, vine weevils usually become a problem in the third season after planting in a pot.
So I suggest repotting every third year when the plant is dormant.

For your prize plants in pots try sticking a fine mesh over the bottom of the pot as the adults don't fly. I hate them as they munch on my heuchera and begonias, every year. I've not had them in blueberry pots so will need to keep an eye on that.

This is my first encounter with them as I tend not to grow in pots for any real length of time, normally I've killed the plants myself by now. I'm not stumping up for nematodes, so covering the surface or repotting looks to be the only way.... either that or grass seed.

Insect barrier glue around the pots would stop the adults crawling up. Or raise the pot up on stilts resting in saucers of water.

best advice is to check nearby pots and to replant with clean compost in a different place - weevils don't travel far, but can be a a bugger to remove.

Usually turns out the infestation came from a plant bought in a pot which already had them.

At the end of the growing season I have been scraping off as much of the compost as possible and leaving the roots in a bucket of water for a couple of days and then repotting. Do not know if this is good for the plant but the white grubs have disappeared [so far]

12 hours is probably enough time submerged.
This is probably speaking to soon, but I haven't had them for some years now.

Anybody had any sucess with the ideas on this thread as they are a pain here. Have a couple of (below link) trough saucers sat together on a stool in greenhouse and have found they like it ie find about 1 weevil per day underneath for sending to the weevil pearly gates. As such would think there must be some forms of traps that would work

Why a mesh over the bottom of the pot mcdood? Would the adults not get in over the top?

Trap trial below page 26 -30. I cant find the commercial vine weevil trap for sale on line

Interesting link it-never-rains. Those other weevils would be toast if I found them in my garden- they look to much like the baddy for their own good.
