Here is a link that might be useful: Plastic grow bags

Dave, thanks for the links, and pardon my possible error, but I do not find the tall bags I am looking for on either of those links. I don't need the most common sizes; I need TALL bags, like a Pringles can but a little wider so the tap roots have room to grow. If they sell what I'm looking for, please give me specific directions.

Thanks,
John

Well there is Tubex http://www.arborday.org/shopping/trees/TreeDetail.cfm?ID=271

and Rootmaker http://www.arborday.org/shopping/trees/TreeDetail.cfm?ID=269

but they are quite a bit more expensive. The easiest and least costly I know of are the ones I linked above. You just roll them into a tube of whatever size you want depending on the size of your cuttings, stand it up, separate the sides into one chamber with a bottom, and fill 1 chamber of the tube. For example the 1 gallon bags are 10" tall so rolled in 1/2 you end up with 3" in diameter, 10" tall tube.

You can also make your own rooting tubes out of any 3-4mil thick roll of plastic. Just cut a piece in the dimensions you want (height x finished diameter), turn it into a tube, overlap and tape the edges with duct tape, fold in the bottom like and envelope to seal it off, and melt in drain holes with any hot metal object - I use a soldering iron.

Hope this helps.

Dave
