    I have some large cymbidiums that need repotting. It will cost me a fortune to buy the orchid bard in small bags at the garden center. Does anyone know if mulch would work just as well? I can buy that in bulk.

    A cymbid mix includes bark, but using the bulk stuff like you use on your garden usually comes with bugs. A good mix includes some sand, bark, perlite and peat moss. You can throw a handful or two of plain old dirt and some time release food also. It must be a very open humousy mix...think of the junk at the edge of a pond or underneath the trees in a woods. The top layer is made of decaying bark, some dirt, some mossy stuff, leaves, etc. Try to replicate that sort of thing in your mix.
    Good Luck

    Very good. This spring I'll get the wheel barrow out and make a mix rather than just use the bark in the bags sold at the garden center. Thanks for the advice!

    I just finished repotting some of my cymbidiums. I went with s/h and used Aliflor clay pellots in 2 quart lemonade pitchers and 1 gallon lemonade pitchers depending on the size of the cym. The koolaid pitchers have handles to make carrying the plants in and out a bit easier!

    Some growers here even add some styrofoam peanuts to make the mix more "breathable".

    i had the same thought! after going through 6 bags of bark and several bags of phal mix, i noticed the huge landscaping bags of bark. i've learned that you should soak your bark for a day before using it, so that should take care of any bug problem. note: i am just starting out so have no super expensive or rare orchids. i figure it's worth a shot. i grow my orchids on a semi enclosed patio, so it's not like a bug won't find them if it wants. i've also seen the packing peanut thing and used them in the bottom of most of my pots. styrafoam floats, so if i try to soak the orchids all the potting mix wants to float out. another thing, lots of growers mount orchids on a tree branch. i doubt it was sterilized!

    Not so sure using landscaping bark for orchids is a good idea. I *think* I read on here someone said that there is some chemical(s) or dye that will not be good for orchids. I would do a bit more research since orchids can be quite expensive sometimes.

    Cheers,
