Replanting strechy stems

How to fix the stretch
Now, after you took care of the cause of the problem it is time to fix the rest. Now the usual method would be to place to plant into a pot or bucket that is big enough to bury the entire overstretched part of the plant – but this brings a new problem. Your babies will then not fully use the soil surrounding it, so not root thru it but rather build only roots around the walls and bottom of the bucket. Now this can cause things from simply wasted volume to the roots can not supported the weight from the soil if you lift your plant at the stem – causing it to rip off and die.

If the strech is very severe:

I just cut off the lower leaves, where there's stretch, and cover it up with soil to the first set of leaves that doesn't have major stretch.

Of course that was when I had stretch. If you have stretch, you're gonna keep on having it until you get more light.
