vine weevil

Just what is 'vine weevil compost'? Vine weevil seem to prefer compost with peat but will thrive in anything!

vine wweevil is something you dont want surley

If you mean Vine Weevil treated compost I don't know if that exists but there are very good V.W treatments available I used to have a great problem with them but for two seasons sprayed my pots with the treatment I purchased and have no problem now. If you grow Begonias, when you take them from the pots put your glasses on!!!! and go through the peat systematically and kill every maggot you see, thats where my odd ones hang out
Also check by running your fingers around under the rims of any pots you have during the summer, if the Vine beetle is in residence that is where you will find them.
