Hi all.. have lost a pot of primrose already and now a second is going. Noticed this one earlier and have washed off the soil and repotted and hope that i got the little devils out! I brought the plants at great expense and the seeds aren't cheap (and i can never seem to grow them!!!)
My question is.. 1) whats the best thing to use at this time of the year to kill the grubs.. and 2) Do primroses suffer as much when planted in the ground and not a pot?
I have had problems with vine weevil in my greenhouse pot plants for the past few years, there are a couple of vine weevil killer water on drenches you can use (Not for use on edible plants) . There is also a safe nematode control available through mail order which can be used in the garden soil or in pots when the temperature starts to warm up , I going to try this solution this year as I am not too keen on using chemicals. I have never found the grubs in the garden soil only in pots with peat in them.
