What happend to my bulbs, gross! & questions.
So I planted over a 200 bulbs 1/2 which were Iris bulbs, not rizhomes. They didn't flower last year and nothing but a couple of gladiolas came up this year. So I dug it all up. In the area where the iris was I only found about 6 bulbs which had rooted but nothing else. No evidence of infestation, moles etc... only a few grubs but nothing overly concerning. Then I dug up over by my deck, this area that had the majority of gladiolas, lillies, and several other bulbs. The few bulbs I found were very mushy and when opened covered in hundreds of tiny white bugs that look like tiny grains of fast moving rice. I have reseached every bug I could find and nothing quite looks like what I found. Not grubs, whitefly, bulb mites, and several other varieties. When I described them to my local nursery he said thrips but when I looked those up, not those either. This area was so infested I couldn't believe it. I used a bayer grub plus and its been sitting for over a week. I planted morning glory seeds right next to this patch and its thriving. I was going to replace the dirt and replant this weekend. But I am wonderign if I need to treat under my deck and what should I use so this area does not become infested again.
