I recently received some cuttings from a member, and did my usual method of rooting. Yesterday I noticed one with a lot of leaves and quite a few roots, so I took it out of it's baggie and was amazed at the lenghth of it! The roots were at the bottom and the leaves were coming from the tip. I had no choice. Couldn't cut it. Too late for that!
It wouldn't fit into a regular 20 oz plastic cup with another on top. Too tall already!!
JD helped me figure out a way. We sliced up 3 tall bottles, and used one for the middle section. Call it creative, but it took a long time! There were so many leaves, I did spray inside the bottle to help those leaves stay moist until the roots can support them.
I have several cuttings showing root initials and green shoots, so I went through them all, and made sure they are all short enough to fit into my two cup system!
Here's what we ended up with!
