Hi @kimbibong99 and  to the site. I'm afraid you've commented on an article, so your question was easy to miss. I'll ask for this thread to be moved to the Orchids forum, where it will get more visibility (even as a Plant Admin I cannot move comment threads on article).@Ursula, @BigBill, @sugarcane, @hawkarica - perhaps one of you can help with this question?

| The white fuzz you see is actually scale insects, white scale known as Boisduval scale. If left untreated, these little sucking insects could suck the life right out of your plant! Easiest treatment is to use a little rubbing alcohol, 70% Isoprpyl, on a Q-tip. Dip the cotton swab in alcohol dabbing it on the scale insects. Let us sit a couple of minutes then thoroughly rinse the alcohol off the plant. Those insects will be dead. Keep watch on the plant, and other plants, because these "buggers" spread easily and rapidly. Re-treat as needed. Always rinse off the alcohol!!! There are other ways to treat outbreaks of white scale but in my experience this control is the easiest and most effective treatment. Good luck! The key to orchid growing is to match the orchid to your conditions. |

| We would be happy to diagnose the black spot issue with images and a description of the problem. Include information such as watering practices, are the spots getting bigger, etc. since several "black spot" problems can occur, the more information that you can provide, the more accurate our diagnosis can be! It is always a pleasure to help. Don't hesitate to ask. Hey Australis!!!  The key to orchid growing is to match the orchid to your conditions. |
