    Fert,s that have urea based nitrogen are normally not reccomended for orchids.I haven,t tried any so can,t say if it,s just "popular myth" or true.

    There is no problem in using high in nitrogen fertilizer in orchids as long as they are in their "active" stage. mostly young orchids

    supposedly urea takes a while to be broken down into usable nitrogen (bacteria do this). for many orchids, the urea is theoretically flushed out of the pot way before this process can happen. that is the reasoning why people say to avoid urea-containing fertilizers. not so much that it causes harm, but that it doesn't produce usable nitrogen.

    then again I see people growing perfectly good plants with peters 20-20-20.

    I personally use dynagro, which does not contain urea. I bought a stash a while ago and haven't purchased fertilizer in like 8 years.

    Jason is correct. I don't think that it is because it will hurt the plants. The issue is just as Jason said the urea will not be able to be used by the plant because the nature of the growing media moast orchids are gorwn in does not contain the proper nitrogen fixxing batceria to process the urea and turn it into usefull nitrogen for the plant. Those tyles of bacteria are found in soil based potting mixxes. So for them to be effective you want to use a urea free firt to have a benefit from the nitrogen.
