Can anyone help me identify these pests?
I got a beautiful white orchid about a month and a half ago and within the first week all the flowers had fallen off. No big deal, the plant still appeared healthy so I followed advice found on the Internet to cut the stem above the first knot or future bulb and continued to feed and water it and give to plenty of sun. The leaves still appear bright green and healthy, but now the stem has turned dark at the top and is yellowing all the way down toward the base of the plant. I've also observed tiny light brown bugs at the top of the stem, but they crawled back into the stem before I could get a good photo. Can anyone help me?
