I've got a little greenhouse to get seedlings started and to protect potted vegetables until a bigger, albeit temporary hoop greenhouse can be built (happening now...).
Last night I lost a dozen seedlings...the green, seed leaves were eaten. I spent hours looking at the bottom of the flats, pots...nothing. Only the seedlings on top of my potting bench were accosted so far...weird.
I am in a hostile place for gardens...have been here for only 6 months but see that a greenhouse is the ONLY way to grow anything. I am in the same zone as most of Alaska!
My first thought was slugs...baby ones, yet no sign. No slime trails...cleaned up debris under and around my seedling flats and put in bucket with water to see if anything crawls out. So looked up the millipedes, no sign, and now I think maybe tiny 'army worms'?
I live in Central Oregon. Freezing every night getting up to 70 degrees or more in the daytime. Also, finding lots of tiny chunks of recently eaten seedling leaves in the debris. Confusing. I am very high in the gardening professional arena...but this is new, this place is new and I want to find the culprit before I decide how to deal with this. Bought expensive, non-gmo seed and get attached to my 'babies'. Any ideas?
