Hi i am completly new to the orchid species i dont know much about them at all. at first this didnt seem to matter because i bought an orchid over the summer on sale and brought it home and it was doing fine. I planted it in peat moss and sphagnum moss becasue i didnt know any better. now my orchid is acting wierd. it flowered and had 6 or so buds and 3 of them bloomed and then they all fell off about 2 days later. All except for one flower and that died a day later. That was just one orchid, for christmas my couson sent me a Cattleya from Kauai and i decided that i should find out a little more on these plants, so i read up on them. This is a very hard species to look up information on because there are so many different things said i dont know what to go by. Well what i wanted to know was i read the back of the bag of this orchid mix that i brought from wal mart how to plant the plant and use the mix. i used it today to replant the two orchids. Now i just read on a websie that i should have mixed that with bark. Do i have to have bark in the mix. This mix says it is made of, Western Fur bark, horticultral charcoal and a natural mineral that has been kiln fired to allow permanent ceramic nuggets containing thousands of pore spaces, that hold water and oxygen for improved moisture and nutrient retention. Now do you think that, that sounds good and that i wouldnt need anything else to go in with them. Im just trying to keep them alive hear...and thats doing fine they just arent blooming. Also about the first orchid which is a dendrobium i was moving fro the window the one day to clean and the flower stalk broke. about half way down. A new one grew from the side of that one right underneath where the old had been is that bad or going to harm the plant in the future. One other thing, do i need to prune my orchids? If so how would i go about doing that?
