I only have 3 orchids at this time. All 3 for phal's. I am limited on space at home so I do not have a lot of plants but most of mine fall under the category of cacti and succulents. Last year I bought my first orchid at Aldi's. It started to rebloom but then I lost the buds. Still a live though. My other two I bought about 2 months ago from Lowe's after they had bloomed out. The one has rebloomed for me. (Yay!) and has a 2nd bud I hope will open soon. The 2nd one is why I joined because it has black spots growing in the underside of a leaf and I am trying to find out what it is.
You should be able to post pictures now you have mode over 5 posts, so it might be a good idea to post one in either the beginner section, or in the Pests & Diseases section which shows the leaf you are worried about and asks for help (if you haven't already). Pictures are always good when looking at problems.
