I have just converted part of my garden (Former lawn) into two raised beds and planted a variety of vegetables.
However my transplanted lettuces appeared to have their low lying leaves attacked/ate by something over the first couple of nights. The main stems appeared to be intack but the leaves were cut off with some leaf debris left lying on the soil surface. I had thought this maybe bird or slug, so I covered with a net and used some slug pellets (even though no slime was visable).
However the attacks have continued and I have since dug up one of the worst affected lettuces which revealed a few greyish/brown grubs which I think look like leatherjackets. Following this discovery it appears the other lettuces are been pulled into the soil and one has been cut off at soil level.
Is this the work of leatherjackets? and what other vegetables do leatherbacks attack?
I have rows of peas, red onions and carrots which appear to be growing well and wonder if these will be attacked now that the lettuce has gone. However I am looking to replace the lost lettuce crop and plant some cabbage and potatoes within the raised bed however this time I will be lining the beds with plastic sheet and using riddled soil/compost which should hopefully prevent this issue.
Any ideas/advice most appreciated.
