hi am getting cuttings rooting but some of them are getting the roots in the middle.
well its ot comfortable to get them planted to soil like that
can i cut the lower part down, below the roots?

just plant it deeper and leave one node above the soil.

So if I understand roots are pushing out in the middle of cutting not at the "bottom" where you like them to?  It's probably not a good idea to cut-off part of the cutting when it is in such a fragile state.  I would pot the cutting up in a deep enough pot/cup so that the rooted portion is well below the soil line.  I have one cutting where roots are coming out near to the top where a green bud is swelling so I will need to do this as well, except in a more extreme way, and will probably end up with the green bud just barely visible above the soil line.

problem is branches were about 12 inches long so.....
my initial pots are plastic cups 5 inches long.

Bury as much as you can in the soil, any left above the soil line will wither off. If need be lay at an angle. The entire stem has nutrients for those roots so cutting it after the roots have formed may cut off too much of the internal fluid flow.  You cannot assume that the section below the roots is not suppling resources for the middle roots. If the end looks dry and dead, then you may do  ok to cut off some, but generally its best to leave it alone.

ok i guess ill have to find taller cups

OK, 12" cutting is fairly long, depends on the activity of the nodes

I've used the long slender water bottles, with the top cut-off and holes introduced in bottom and sides, in such situations before.

   I've always found the longer cuttings to be more troublesome...so now I always cut them down to two 6" cuttings or three 4" cuttings(depending on how many nodes are showing)...lot less trouble for me, and the bonus is more trees from the same number of original cuttings...win-win for me.  :)

If you have a Starbucks near you, go there and ask if you can buy a few  of their  Venti cold beverage clear cups from them. They will probably ask how many, you say "like 4 or 5" with a slightly questioning look on your face. And chances are they usually just give them to you, then you tip them something.

They also have one larger called a Trenta, but it isn't too much taller than the Venti, just fatter(which is how we become if we were to have one of their iced treats in that tanker). They wouldn't sell me the Trenta, my guess is they don't stock a lot of those cups.

The Venti cup is 6.5 inches tall. If you really needed, you could do some fancy cutting and tape work of a second cup onto the first cup; basically adding an extension and making it taller. Do what you have to do to get those roots under the medium at least an inch or two. And in the future, cut your cutting to a manageable size before you initiate your rooting process.

Hope that helps and good luck.

Calvin, I tried that but probably made the mistake of speaking to the manager and he said he couldn't sell them.  So now I have a co-worker saving the venti cups for me.  Maybe I'll try again when the shop is slow and the manager isn't around.

I would not recommend cutting any live tissue off the cutting just to make it fit into a cup.  I've done this in the past and my observation is that it tends to weaken the cutting and slow later growth.  It could work, but I don't see any advantage.

Where there is a will there is a way, though, and you've got a couple options that don't require cutting it:
1.  Plant it horizontally in a cheap (about $1 at home depot) plastic shoe box thing.  Put it maybe 1/2 inch below the surface.  Try to take any nodes that look promising for a main stem and face them towards the surface (approximately). 
2.  Use a 2 or 3 liter soda bottle.  Make sure you prepare it properly and think it through before you put the cutting in.  Cut a few holes in the bottom for drainage.  I've even gone so far as to slice the thing lengthwise, and then tape it up so that when it's time to pot it up, it's easy to get the cutting out without damaging any roots. 
3.  If you have a 1 to 3 gallon pot, go ahead and plant it, with the topmost root about 1/2 or 1 inch below the surface.  You won't be able to see the root activity, but just plant it and leave it alone and you'll be fine.

Best of luck

Here in the US every gas station sells 52 Oz drink cups which work well.  Straight sided water bottles as Rewton mentioned are also good and easier to tape together than drink cups.

i have lots of from the tree so i dont care.. its just that the big branch gave realy nice roots  and i wanted to take advantage of that.
anyhow i cut it one node below for extra safety.
thanks

NEVER argue with roots. Figure out some way to use them where they grow.

OPPS, a day late. I cut a couple last night. I am having the same problem on a few of my cuttings.

i hope the boat stays steady :)
